continuation of U.S. patent application Ser. No. 16/443,266, filed

Application No. 62/693,230, filed Jul. 2, 2018; the contents of
each of which are incorporated herein by reference in their
entirety.
BACKGROUND
[0002] Most households rely on the municipal power grid to supply
their home energy needs. Municipal power grids typically utilize
hydroelectric, nuclear, or fossil fuel power generation in order to
supply a substantially constant and reliable source of electricity
for homes, businesses, and public buildings.
[0003] In spite of the general reliability of municipal power
grids, there are instances in which the municipal power grid is
unable to supply electricity. For example, storms, earthquakes,
accidents, maintenance, and equipment failure can all result in the
interruption of the municipal power supply. In these situations,
individuals and organizations may seek to implement backup or
alternative power supply options.
[0004] Many individuals and organizations own combustion generators
as a backup power supply or as a portable power supply solution.
When the municipal power grid is interrupted, combustion generators
can be used to generate electricity by burning fossil fuels.
Individuals and organizations also use portable combustion
generators to power electronic appliances at locations such as
campsites, parks, and construction sites.
[0005] While combustion generators can be an effective solution in
some instances, combustion generators also suffer from many
drawbacks. For example, combustion generators are often very
inefficient. When activated, they typically burn a fixed amount of
fuel, regardless of the needs of the appliances that they are
powering.
[0006] Furthermore, many appliances need to receive electrical
power only intermittently. Combustion generators will continue to
use fuel and generate electricity even during the periods when an
electronic appliance does not need electricity. Although some
generators have a low power mode, the low power mode still burns
fuel continuously regardless of load. As an example, if a remote
application requires 5 V, the combustion generator will maintain a
minimum operating output that may greatly exceed the actual need,
thereby wasting energy. Also, generators often have fixed amounts
of fuel and therefore a fixed amount of time they can operate
without receiving additional fuel.
[0007] Additionally, campsites and parks typically restrict the
hours during which combustion generators can be operated. Other
venues, such as trade shows or convention halls, may prohibit the
use of generators entirely. Noise and fumes that are created often
mean that combustion generators are placed at a distance, which
creates power transmission problems.
[0008] While the municipal power grid is typically a reliable
source of electricity for appliances, light fixtures, and other
stationary electrical devices, the municipal power grid has serious
limitations when it comes to providing electricity for devices that
are not stationary. For example, electrical yard work tools such as
leaf blowers, weed whackers, hedge trimmers require long extension
cords if they are to receive power from the municipal power grid.
This leads to serious drawbacks such as the high cost of
sufficiently long extension cords and the hassle of extension cords
become entangled and unplugged.
[0009] To deal with such drawbacks, manufacturers of power
intensive portable electronic appliances have made battery-powered
portable electronic devices. However, due to limited capacity, the
batteries often drain before work is completed. The batteries must
be recharged before the batteries can be utilized again.
Additionally, charging these batteries requires specific cords and
adapters that become lost or mixed among several cords and
adapters.
[0010] What is needed is a system and method that solves the
long-standing technical problem of providing alternative energy
supply and storage solutions that are efficient, flexible, and
simple in both stationary and portable situations.
SUMMARY
[0011] Embodiments of the preset disclosure provide a system of
power cell modules that is effective in stationary and portable
situations and that is effective for both large-scale and
small-scale energy supply requirements. The power cell modules can
be stacked together in a bank of power cells to jointly power
electronic appliances. Individual power cell modules can be removed
from the bank of power cells in order to provide power to portable
electronic appliances, without interrupting the power provided by
the bank of power cells to other electronic appliances.
[0012] In one embodiment, each individual power cell module
provides multiple voltages to a multi-voltage bus. When the power
cells are connected together in a bank or stack, the multi-voltage
bus is connected across all of the power cells and receives the
multiple voltages from each power cell. Each power cell includes
user power outputs that carry the multiple available voltages and
enable users to connect to any of the available voltages without
operating any switches.
[0013] Accordingly, embodiments of the present disclosure provide a
power source and energy supply solution that is robust enough to
power a home, flexible enough to conveniently power portable
equipment, and simple enough that users can easily implement the
solution without risk and without involving a professional
electrician.
[0014] In one embodiment, the system provides stackable,
interchangeable, reconfigurable, independent, portable power and
energy devices for the purposes of power generation, energy capture
and storage solutions. The advantages of flexibility in the size,
both physical and in feature and function, are numerous. System
priorities can now become the primary driver in the decision
process of stacking a system or choosing an individual module for
the specific task. Some of the priorities that can be taken into
account with such a system include but are not limited to physical
strength of an individual user, available size and space at an
intended destination, and need to capture/store energy at the
location, the location itself. For example, a vehicle may simply
need assurance to power a dead starter battery. A relatively low
output power cell module may be connected to run an application for
a short period of time or may be used with multiple power cell
modules to run for a longer duration. A power cell module or stack
of power cell modules will provide energy to a device with
intermittent power needs only when needed, unlike a combustion
generator that will continue burning fuel to generate electricity
regardless of the need.
[0015] In one embodiment, the power cell modules are safe and
movable by a person. Regardless of the size of the total system,
the power cell modules can be transported, stored, recharged, and
used for the purposes of providing, storing or capturing
energy.
[0016] In one embodiment, because the system can be made up of one
or more power cell modules, the system is a better design,
holistically, situationally, economically, sustainably, and with a
more utilitarian approach than other designed systems. The system
has the advantage of scaling up or down depending on the specific
application.
[0017] Embodiments of the present disclosure address some of the
shortcomings associated with traditional stationary and portable
energy solutions. The various embodiments of the disclosure can be
implemented to improve the technical fields of energy storage,
off-grid energy solutions, emergency energy solutions, and portable
power supplies.

DETAILED DESCRIPTION
[0032] Embodiments will now be discussed with reference to the
accompanying FIG.s, which depict one or more exemplary embodiments.
Embodiments may be implemented in many different forms and should
not be construed as limited to the embodiments set forth herein,
shown in the FIG.s, and/or described below. Rather, these exemplary
embodiments are provided to allow a complete disclosure that
conveys the principles of the invention, as set forth in the
claims, to those of skill in the art.
[0033] FIG. 1 is a block diagram of a power cell module 102,
according to an embodiment. The power cell module 102 includes a
plurality of batteries 104, voltage combination circuitry 106, a
multi-voltage bus 108, control circuitry 110, inter-module
multi-voltage bus connectors 112, user power outputs 114, voltage
conversion circuitry 113, inter-module communication circuitry 117,
sensors 116, and a display 118, according to various embodiments.
The components of the power cell module 102 enable the power cell
module 102 to function as a standalone power supply or to connect
with other power cell modules as part of a bank or stack of power
cell modules that collectively provide electricity to one or more
electronic appliances.
[0034] In one embodiment, the power cell module 102 includes a
plurality of batteries 104. The batteries 104 can include one or
more of lead acid batteries, lithium-ion batteries, Nickel-Zinc
batteries, Nickel-Cadmium batteries, Nickel-metal-hydride
batteries, and Zinc-Magnesium oxide batteries. In one embodiment,
each of the batteries 104 within a given power cell module 102 is a
same type of battery. Alternatively, in some embodiments, the
batteries 104 in a given power cell module 102 can include multiple
types of batteries.
[0035] In one example, in accordance with one embodiment, the power
cell module 102 includes four individual batteries 104. The
individual batteries 104 include 12 V lead acid batteries. The
power cell module 102 utilizes the 12 V lead acid batteries to
provide electricity to one more electronic appliances either as a
standalone power cell module 102, or as part of a bank or stack of
power cell modules 102 that collectively provide electricity to one
or more electronic appliances.
[0036] In one embodiment, the power cell module 102 includes
voltage combination circuitry 106. The voltage combination
circuitry 106 is coupled to the terminals of the batteries 104 in
order to provide, simultaneously, multiple output voltages from the
batteries 104. The output voltages provided by the voltage
combination circuitry 106 correspond to various series and parallel
connections of the batteries 104. Thus, each output voltage
provided by the voltage combination circuitry 106 corresponds to a
parallel connection of multiple of the batteries 104, a series
connection of multiple of the batteries 104, or a combination of
series and parallel connections of multiple of the batteries
104.
[0037] In one embodiment, the voltage combination circuitry 106
provides the multiple output voltages simultaneously. For example,
the voltage combination circuitry 106 can include one set of
terminals that provide an output voltage that is a series
connection of all the batteries 104, one set of terminals that
provides an output voltage that is a parallel connection of all of
the batteries 104, and a set of terminals that provides an output
voltage that is a parallel connection of two sets of batteries
wherein each set of batteries is a series connection of two or more
of the batteries 104.
[0038] In one embodiment, the voltage combination circuitry 106
includes circuit components among the various connections that
prohibit short-circuits among the various output voltages. For
example, the connection between two terminals of two of the
batteries 104 can include one or more diodes configured to prohibit
the flow of current in an undesired direction. This can ensure that
the voltage combination circuitry 106 can provide various
combinations of voltages without short-circuiting and without the
need of a multiplexer, according to one embodiment.
[0039] In one embodiment, the voltage combination circuitry 106
provides all the output voltages simultaneously. The voltage
combination circuitry 106 does not generate the various output
voltages via transformers, voltage multipliers, or charge pumps,
according to an embodiment. Instead, the voltage combination
circuitry 106 provides each output voltage as series, parallel, or
series and parallel connections between the various terminals of
the batteries 104, according to one embodiment.
[0040] In one embodiment, the power cell module 102 includes a
multi-voltage bus 108. The multi-voltage bus 108 receives the
output voltages from the voltage combination circuitry 106. The
multi-voltage bus 108 includes a plurality of voltage lines, one
for each output voltage of the multi-voltage bus 108. Thus, each
voltage line of the multi-voltage bus 108 carries a voltage
corresponding to one of the respective output voltages from the
voltage combination circuitry 106. Accordingly, the multi-voltage
bus 108 simultaneously carries all output voltages from the voltage
combination circuitry 106, according to an embodiment.
[0041] In one embodiment, the multi-voltage bus 108 is designed so
that when the power cell module 102 is connected in a bank of power
cell modules, the multi-voltage bus 108 connects to a corresponding
multi-voltage bus from all of the power cell modules of the bank of
power cell modules. Accordingly, when the power cell module 102 is
connected in a bank of power cell modules, the bank of power cell
modules has a collective multi-voltage bus that is the continuation
of each of the multi-voltage buses of the various power cell
modules of the bank of power cell modules.
[0042] In one embodiment, when the power cell module 102 is
connected to a second power cell module, each line of the
multi-voltage bus 108 is electrically connected to a corresponding
line of a multi-voltage bus of the second power cell module. If the
multi-voltage bus 108 includes three lines each carrying either a
respective output voltage V1, V2, or V3, when the power cell module
102 is connected to the second power cell module, the V1 line of
the multi-voltage bus 108 is connected to the V1 line of the
multi-voltage bus of the second power cell module, the V2 line of
the multi-voltage bus 108 is connected to the V2 line of the
multi-voltage bus of the second power cell module, and the V3 line
of the multi-voltage bus 108 is connected to the V3 line of the
multi-voltage bus of the second power cell module. Accordingly, the
multi-voltage bus 108 of the modular battery power cell 102 and the
multi-voltage bus of the second power cell module form a collective
multi-voltage bus including the V1 line, the V2 line, and V3 line.
Each additional power cell module connected into the bank of power
cell modules joins the collective multi-voltage bus. Each power
cell module provides V1, V2, and V3 to the collective multi-voltage
bus.
[0043] In one embodiment, the advantage of the multi-voltage bus is
that users do not need to manually control the power cell modules
to provide a particular desired voltage. If this were not the case,
then it is possible that each power cell module would need to be
manually or electronically configured by the user in the exact same
way to avoid short-circuits or other electrical problems that can
come with mismatched voltage connections between the various power
cell modules. Instead, each power cell module, in accordance with
one embodiment, provides all voltages and contributes to the
collective multi-voltage bus. As will be set forth in greater
detail below, this enables a very simple set up that requires
little or no electrical knowledge from users before they can safely
and effectively use the power cell modules either individually or
in a bank of power cell modules.
[0044] In one embodiment, the power cell module 102 includes
control circuitry 110. The control circuitry 110 can include one or
more processors or microcontrollers that control the operation of
the power cell module 102. The one or more processors can execute
software instructions stored in one or more memories in order to
control the functionality of the various aspects of the power cell
module 102. The one or more processors can also be controlled via
manual interaction or wireless communication controlled inputs. The
control circuitry 110 can operate in accordance with firmware
stored in the one or more memories.
[0045] In one embodiment, the control circuitry 110 is able to
selectively connect or disconnect the voltage combination circuitry
106 from the multi-voltage bus 108. For example, if the batteries
104 are depleted, or in a fault state, that the control circuitry
110 can operate switches are circuit breakers that disconnect the
output voltages of the voltage combination circuitry 106 from the
multi-voltage bus 108.
[0046] In one embodiment, the power cell module 102 includes
sensors 116. The sensors 116 sense various aspects of the power
cell module 102. The sensors 116 provides sensor signals to the
control circuitry 110. The control circuitry 110 can control the
components and functionalities of the power cell module 102
responsive to the sensor signals from the sensors 116 and in
accordance with internal logic of the control circuitry 110. For
example, the control circuitry 110 can disconnect the voltage
combination circuitry 106 from the multi-voltage bus 108 responsive
to the sensor signals.
[0047] In one embodiment, the sensors 116 can include multiple
sensors that sense the voltages output by each battery 104. The
voltage sensors can output sensor signals to the control circuitry
110 indicative of the voltage outputs of each battery. The voltage
sensors can also sense the output voltages provided by the voltage
combination circuitry 106 and can provide sensor signals to the
control circuitry 110 indicative of the output voltages provided by
the voltage combination circuitry 106. The control circuitry 110
can control components and functionality of the power cell module
102 responsive to the sensed voltages. In one embodiment, the
voltage sensors are part of the control circuitry 110.
Alternatively, the voltage sensors can be external to the control
circuitry 110.
[0048] In one embodiment, the sensors 116 can include current
sensors. The current sensors can sense the current flowing from
each of the batteries 104. The current sensors can sense the total
current flowing from the power cell module 102. The current sensors
can also sense the current flowing from the batteries 104 through
each line of the multi-voltage bus 108. The current sensors output
sensor signals to the control circuitry 110 indicative of the
various currents flowing in and from the power cell module 102. The
control circuitry 110 can control components and functionality of
the power cell module 102 responsive to the sensed currents. In one
embodiment, the current sensors are part of the control circuitry
110. Alternatively, the current sensors can be external to the
control circuitry 110.
[0049] In one embodiment, the sensors 116 can include temperature
sensors. The temperature sensors can sense the temperatures of the
batteries 104. The temperature sensors can sense a temperature
within the power cell module 102. The temperature sensors can also
sense the temperature of various components within the power cell
module 102. The temperature sensors can output sensor signals
indicative of the various temperatures to the control circuitry
110. The control circuitry 110 can then take action responsive to
the temperatures. For example, the control circuitry 110 can
disconnect the voltage combination circuitry 106 from the
multi-voltage bus 108 to stop the flow of current in response to an
indication that the batteries 104 overheating.
[0050] In one embodiment, the power cell module 102 includes user
power outputs 114. The user power outputs 114 include various ports
each outputting a particular voltage. For example, the user power
outputs 114 can include one or more output ports for each voltage
carried by the multi-voltage bus 108. A user can connect an
electronic appliance to one of the output ports in order to provide
power to the electronic appliance. The user can connect the
electronic appliance to the output port that carries the correct
voltage for the electronic appliance. The power cell module 102 can
also include user power inputs that can receive electrical
connections to provide power to the power cell module 102.
[0051] If the multi-voltage bus 108 includes three output voltages
V1, V2, and V3, the user power outputs 114 can include multiple
output ports for each output voltage. Each output port can
correspondence to a particular type of connection. Accordingly,
there may be multiple types of output ports for a single output
voltage to fit multiple types of electrical connectors for
electronic appliances. In one embodiment, the user power outputs
114 can receive dongles or adaptors that fit the output ports to
particular common connection schemes. In one embodiment, if an
electronic appliance requires a DC voltage other than those carried
by the multi-voltage bus 108, then an adapter can be plugged into
one of the output ports, receive the voltage from the output port,
and step the voltage up or down in order to achieve the voltage
required by the electronic appliance.
[0052] In one embodiment, when the power cell module 102 is
connected in a bank of power cell modules, if a user plugs an
electronic appliance into one of the user power outputs 114, power
is provided to the electronic appliance from each power cell module
connected to the multi-voltage bus 108. Thus, when an electronic
appliance is plugged into the power output of one power cell module
in a bank of power cell modules, the electronic appliance draws a
portion of the overall current from each power cell module
connected to the multi-voltage bus 108. Thus, large numbers of
power cell modules can be connected in a bank so that a particular
electronic appliance, or several electronic appliances, can be
powered for a long time by the bank of power cell modules.
[0053] In one embodiment, the power cell module 102 includes
voltage conversion circuitry 113. The voltage conversion circuitry
113 is connected to one or more of the voltage lines of the
multi-voltage bus 108. The voltage conversion circuitry 113
receives one or more output voltages from the multi-voltage bus 108
and generates other voltages. The other voltages can include DC
voltages intermediate to the output voltages of the multi-voltage
bus 108, greater than the highest voltage carried by the
multi-voltage bus 108, less than the smallest voltage carried by
the multi-voltage bus 108, and voltages of a different type than
the voltages carried by the multi-voltage bus 108. The user power
outputs 114 can include one or more output ports for each voltage
generated by the voltage conversion circuitry 113. This enables
users to plug electronic appliances into output ports that carry
voltages other than those carried by the multi-voltage bus 108.
[0054] In one embodiment, because the voltages generated by the
voltage conversion circuitry 113 are generated from the
multi-voltage bus 108, electronic appliances that receive voltages
generated by the voltage conversion circuitry 113 draw power from
each of the power cell modules connected to the multi-voltage bus
108.
[0055] In one embodiment, the voltage conversion circuitry 113
receives a DC voltage from the multi-voltage bus 108 and generates
an AC voltage. The AC voltage is then provided to one or more of
the user power outputs 114. Accordingly, the voltage conversion
circuitry 113 can include one or more inverters to generate one or
more AC voltages. In one embodiment, one of the AC voltages has an
amplitude and frequency corresponding to the amplitude and
frequency of a local municipal power grid. For example, one of the
AC voltages can include 110 V AC at 60 Hz, corresponding to
standard wall voltage in North America and many other areas.
Another AC voltage can include 220 V AC at 60 Hz, corresponding to
the increased voltage at which some electronic appliances operate
in North America and many other areas.
[0056] In one embodiment, in the event of a failure of the
municipal power grid, electronic appliances that normally plug into
the wall voltage, or into the higher than wall voltage, can be
plugged into the power cell module 102 or can otherwise receive
power from the power cell module 102. If the power cell module 102
is connected in a bank of a large number of power cell modules,
then the AC powered electronic appliances can draw power from all
of the power cell modules that are connected to the multi-voltage
bus 108. In one embodiment, the system can be plugged into a
standard wall outlet of a house when the municipal power grid is
interrupted and is not supplying power. A power chord can be
plugged into the wall outlet from one of the power cell modules.
The power cell module converts one of the DC output voltages from
the multi-voltage bus into an AC voltage having the correct
frequency and amplitude for the wall outlet. The AC voltage is then
supplied to the wall outlet. All of the wall outlets that are on
the same circuit can now be powered by the AC voltage supplied from
the power cell module or bank of power cell modules. Before doing
this, the user will need to access the circuit box and trip the
circuit breaker to that circuit so that if the municipal power grid
comes back online there will not be a short circuit. The power cell
module can include protective circuitry to protect the power cell
module in the event of a short circuit. The power can be supplied
via a bank of power cell modules.
[0057] In one embodiment, the voltage conversion circuitry 113 can
receive a voltage from the multi-voltage bus 108 and can convert
the voltage to one or more voltages associated with typical
personal electronic device connectors. For example, many electronic
devices are powered by a specified small voltage, such as 3.1 V or
5 V. Many electronic devices are adapted to receive voltages from
standardized output ports such as USB 2.0, USB 3.0, micro USB, USB
C, or other types of charging ports. The voltage conversion
circuitry 113 can generate the voltages associated with these types
of charging ports. The user power outputs 114 can include multiple
charging ports that fit the various standard ports and that receive
the proper voltages from the voltage conversion circuitry 113.
Users can then plug their personal electronic devices, such as
mobile phones, tablets, ear phones, game controllers, wearable
electronic devices, drones, and other kinds of personal electronic
devices that can be charged from a standard output port, into the
corresponding output ports of the user power outputs 114 in order
to charge their personal electronic devices.
[0058] In one embodiment, the power cell module 102 includes a
display 118. The display 118 can output data or other messages
indicating a current state of the power cell module 102. The
display 118 can indicate the number of power cell modules connected
in a bank of power cell modules. The display 118 can indicate the
current level of charge in the batteries 104, an indication of the
current or power being output by the power cell module 102, or a
length of time until the batteries 104 need to be recharged at the
current power draw. The display 118 can indicate whether there is a
fault condition associated with the power cell module 102. The
display 118 can provide instructions to a user for initializing,
utilizing, or troubleshooting the power cell module 102. The
display 118 can provide data indicating which of the user power
outputs 114 is currently in use. The display 118 can provide
information such as the temperature within the power cell module
102 or the voltage levels of the batteries 104.
[0059] In one embodiment, the control circuitry 110 can control the
display 118. The control circuitry 110 can output messages to the
user via the display 118. The control circuitry 110 can output
instructions to the user for operating the power cell module 102 or
for providing the current status of the power cell module 102 to
the user. The display can also display information pushed to other
power cell modules or connected electronic devices.
[0060] In one embodiment, the power cell module 102 includes
inter-module multi-voltage bus connectors 112. The inter-module
multi-voltage bus connectors 112 electrically connect the voltage
lines of the multi-voltage bus 108 to the corresponding voltage
lines of a second power cell module. The inter-module multi-voltage
bus connectors 112 can include Anderson connectors or other types
of standard or unique connectors that can couple the voltage lines
of the multi-voltage bus 108 to the corresponding voltage lines of
the multi-voltage bus of a second power cell module.
[0061] In one embodiment, the inter-module multi-voltage bus
connectors 112 automatically connect the voltage lines of the
multi-voltage bus 108 to the corresponding voltage lines of a
second power cell module when the power cell module 102 is attached
to the second power cell module. Accordingly, the inter-module
multi-voltage bus connectors 112 can include fasteners that assist
in securely fastening the power cell module 102 to a second power
cell module when stacked together.
[0062] In one embodiment, the power cell module 102 includes
inter-module multi-voltage bus connectors 112 on top and bottom
surfaces of the power cell module 102. Thus, when the power cell
module 102 is connected in a bank of power cell modules 102, the
power cell module 102 can be connected to a second power cell
module below the power cell module 102, and a third power cell
module can be connected to the top of the power cell module 102. In
one embodiment, the power cell module 102 can include latches,
releases, and other connection hardware that enables the power cell
module 102 to quickly attach to other power cell modules and to
quickly be released from other power cell modules.
[0063] In one embodiment, the power cell module 102 includes
inter-module communication circuitry 117. The inter-module
communication circuitry 117 enables the power cell module 102 to
communicate with other power cell modules in a bank of power cell
modules in which the power cell module 102 is connected. The
inter-module communication circuitry 117 can share the status or
condition of each power cell module. In one embodiment, the
inter-module communication circuitry 117 includes wireless
transceivers enabling the power cell modules to communicate with
each other wirelessly. In one embodiment, the inter-module
communication circuitry 117 includes wired connections that enable
the power cell modules to communicate with each other across wired
connections. In one embodiment, the inter-module communication
circuitry can enable the power cell module 102 to establish which
power cell module in a bank of connected power cell modules is the
master or controlling power cell module.
[0064] In one embodiment, the inter-module communication circuitry
can communicate with one or more users. For example, the
inter-module communication circuitry 117 can send alerts to the
user regarding the current state of the inter-power cell module
102, or the bank of inter-power cell modules. The inter-module
communication circuitry 117 can alert the user when the overall
capacity of the bank of power cell modules is low so that the user
can recharge power cell modules or make other provisions for
powering electronic appliances. In one embodiment, the users can
install a dedicated power cell module system application on a
personal computing device, such as a smart phone. The power cell
module system application can enable the user to control or
otherwise communicate with the power cell modules.
[0065] In one embodiment, when the power cell modules are connected
in a bank of power cell modules, one of the power cell modules can
be designated as the master power cell module. Users can be
directed to connect electronic appliances to the master power cell
module, the electronic appliances can then be powered by the entire
bank of power cells via the master power cell. In one embodiment,
the master power cell is substantially the same as the other power
cell modules in the bank power cells. Alternatively, the master
power cells can be a different type of power cell that includes
additional connections and functionality.
[0066] In one embodiment, the power cell module 102 includes a
casing. The components of the power cell module one 102 are
positioned primarily within the casing. The display 118 and the
user power outputs 114 can be positioned on an outer surface of the
casing. The inter-module multi-voltage bus connectors 112 can also
be positioned, at least partially, and an outer surface of the
casing. Inter-module data connection ports and other I/O ports can
be positioned on the outer surface of the casing.
[0067] Those of skill in the art will recognize, in light of the
present disclosure, that a power cell module 102 in accordance with
the present disclosure can include additional components, fewer
components, or different combinations of components than are shown
in FIG. 1, without departing from the scope of the present
disclosure.
[0068] FIG. 2 is a block diagram of circuitry of the power cell
module 102 of FIG. 1, according to one embodiment. With reference
to FIGS. 1-2 and the description of FIG. 1 above, the power cell
module 102 includes four batteries 104a-104d, voltage combination
circuitry 106, circuit breakers 119, a multi-voltage bus 108,
voltage conversion circuitry 113, user power outputs 114, control
circuitry 110, sensors 116, and a display 118, according to various
embodiments.
[0069] In one embodiment, the four batteries 104a-104d are
connected to the voltage combination circuitry 106. In particular,
both the positive and negative terminal of each battery are
connected to the voltage combination circuitry 106.
[0070] In one embodiment, the voltage combination circuitry 106
receives the voltages from the batteries 104a-104d and generates
voltage output voltages V1-V3. In one embodiment, each of the
output voltages V1-V3 corresponds to a series connection of the
batteries 104a-104d, a parallel connection of the batteries
104a-104d, or a combination of series and parallel connections of
the batteries 104a-104d. While the example of FIG. 2 illustrates
three output voltages V1-V3, the voltage combination circuitry 106
can provide more or fewer output voltages than three, according to
various embodiments.
[0071] In one embodiment, the voltage combination circuitry 106
provides the output voltages V1-V3 to the multi-voltage bus 108. In
particular, the voltage combination circuitry 106 provides all
three output voltages V1-V3 to the multi-voltage bus 108
simultaneously.
[0072] In one embodiment, circuit breakers 119 are positioned
between the voltage combination circuitry 106 and the multi-voltage
bus 108. The circuit breakers 119 can break the connection between
the voltage combination circuitry 106 and the multi-voltage bus 108
such that the multi-voltage bus 108 does not receive the output
voltages V1-V3 from the voltage combination circuitry 106.
[0073] In one embodiment, the control circuitry 110 controls the
circuit breakers 119. The control circuitry 110 can selectively
cause the circuit breakers 119 to break the circuit between the
voltage combination circuitry 106 and the multi-voltage bus 108.
The control circuitry 110 can control the circuit breakers 119
responsive to conditions within the power cell module 102. For
example, the control circuitry 110 can receive the sensor signals
from the sensors 116. If the sensor signals indicate a fault
condition within the power cell module 119, then the control
circuitry 110 can cause the circuit breakers 119 to break the
circuit. Additionally, if the sensor signals indicate that the
voltage of one or more of the batteries 104a-104d is too low to
supply power to the multi-voltage bus 108, then the control
circuitry 110 can cause the circuit breakers 119 to break the
circuit. In one embodiment, the circuit breakers 119 include
switches that can be operated by the control circuitry 110 to
selectively disconnect or connect the voltage combination circuitry
106 to the multi-voltage bus 108.
[0074] In one embodiment, the multi-voltage bus 108 includes
voltage lines 121. Each voltage line carries a respective output
voltage provided by the voltage combination circuitry 106.
Accordingly, the multi-voltage bus 108 simultaneously carries all
of the output voltages provided by the voltage combination
circuitry 106. As set forth above, when the power cell module 102
is connected in a bank of power cell modules, the multi-voltage bus
108 and the voltage lines 121 are part of a collective
multi-voltage bus in which all connected power cell modules provide
the output voltages V1-V3 to the collective multi-voltage bus. An
electronic appliance connected to one of the power cell modules in
the bank receives power from each power cell module that is
connected to the collective multi-voltage bus.
[0075] In one embodiment, the user power outputs 114 include, for
each output voltage V1-V3, one or more output ports that carry the
respective output voltage and enable an electronic appliance to be
connected to receive that output voltage.
[0076] In one embodiment, the voltage conversion circuitry 113
receives one or more of the output voltages V1-V3 and generates
converted voltages from the output voltages V1-V3. The converted
voltages can include AC voltages, DC voltages intermediate to the
output voltages V1-V3, DC voltages greater than any of the output
voltages V1-V3, and DC voltages less than any of the output
voltages V1-V3. The voltage conversion circuitry 113 provides these
converted voltages to the user power outputs 114. The user power
outputs 114 include, for each converted voltage, one or more output
ports to which an electronic appliance can be connected to receive
that voltage.
[0077] In one embodiment, the control circuitry 110 is connected to
the voltage combination circuitry 106, circuit breakers 119, the
user power outputs 114, the voltage conversion circuitry 113, the
display 118, and the sensors 116, according to various embodiments.
The control circuitry 110 can control aspects of the functionality
of these components, according to various embodiments.
[0078] FIG. 3 is a schematic diagram of the batteries 104a-104d and
the voltage combination circuitry 106 of FIGS. 1-2, according to an
embodiment. With reference to FIGS. 1-3, and the descriptions of
FIGS. 1-2 above, FIG. 3 illustrates four batteries 104a-104d. Each
of the batteries 104a-104d includes a positive and the negative
terminal with 12 V between the positive and the negative
terminal.
[0079] In one embodiment, the voltage combination circuitry 106
includes wired connections to each of the terminals of the
batteries 104a-104d. The voltage combination circuitry 106 includes
diodes D1-D6 connected between various terminals of the batteries
104a-104d. The voltage combination circuitry 106 provides output
voltages V1-V3.
[0080] In one embodiment, the output voltage V1 is 12 V. The output
voltage V1 corresponds to each of the batteries 104a-104d connected
in parallel. Because each battery provides 12 V, the parallel
connection of all the batteries 104a-104d provides 12 V. The
negative terminal of V1 is connected to the negative terminal of
each of the batteries 104a-104d. The positive terminal of V1 is
connected to the positive terminal of each of the batteries
104a-104d.
[0081] In one embodiment, the output voltage V2 is 24 V. The output
voltage V2 corresponds to the series connection of batteries 104a
and 104b connected in parallel with the series connection of
batteries 104c, 104d, resulting in a total voltage of 24 V. The
positive terminal of V2 is connected to the positive terminals of
the batteries 104b and 104d. The negative terminal of V2 is
connected to the negative terminals of the batteries 104a and
104c.
[0082] In one embodiment, the output voltage V3 is 48 V. The output
voltage V3 corresponds to the series connection of all four
batteries 104a-104d, resulting in a total voltage of 48 V. The
positive terminal of V3 is connected to the positive terminal of
the battery 104d. The negative terminal of V3 is connected to the
negative terminal of the battery 104a.
[0083] In one embodiment, the diode D1 is connected between the
positive terminal of the battery 104a and the negative terminal of
the battery 104b. The diode D2 is connected between the positive
terminal of battery 104b and the negative terminal a battery 104c.
The diode the three is connected between the positive terminal of
the battery 104c and the negative terminal of the battery 104d. The
diode D4 is connected between the positive terminal of the battery
104 a and the positive terminal of the battery 104b. The diode D5
is connected between the positive terminal of the battery 104b and
the negative terminal of the battery 104c. The diode D6 is
connected between the positive terminal of the battery 104b and the
positive terminal of the battery 104d. The connection of the diodes
D1-D6 ensure that the voltage combination circuitry 106 can safely
output all three output voltages V1-V3 without short-circuits.
Those of skill in the art will recognize, in light of the present
disclosure, that other circuit schematics can be implemented to
provide the multiple output voltages while preventing
short-circuits, without departing from the scope of the present
disclosure.
[0084] In one embodiment, the diodes D1-D6 include Schottky diodes.
In one embodiment, the diodes D1-D6 includes 102a-102cener diodes
with a high enough Zener voltage to withstand the highest DC
voltages that could be applied as a reverse bias within the power
cell module 102. In one embodiment, the diodes D1-D6 include p-n
diodes.
[0085] FIG. 4 is a block diagram of a wiring harness 128, according
to one embodiment. With reference to FIGS. 1-4 and the descriptions
of FIGS. 1-3 above, the wiring harness 128 is part of the voltage
combination circuitry 106. The wiring harness 128 facilitates the
connections by which the output voltages V1-V3 are generated.
[0086] In one embodiment, each of the batteries 104a-104d takes
part in generating each of the output voltages V1-V3. The wiring
board includes, for each combination of battery and output voltage,
a pair of wiring slots 130 and a pair of screw slots 132. In each
pair of wiring slots 130, one wiring slot is connected to the
positive terminal of the corresponding battery and the other slot
is connected to the negative terminal of the corresponding battery.
The screw holes 132 are each configured to receive a screw. When a
wire is placed in the wiring slot 130 below a screw hole 132, and a
screw is screwed into the screw hole 132, the wire is forced into
electrical contact with the corresponding battery terminal.
[0087] In one embodiment, wires are placed in each wiring slot 130
and screws are fastened into each of the corresponding screw holes
132. The wires can then be connected in the series and parallel
connections to generate the output voltages V1-V3. The wires
plugged into the screw holes 130 in the column V1 are used to
generate the output voltage V1. The wires plugged into the screw
holes 130 in the column V2 are used to generate the output voltage
V2. The wires plugged into the screw holes in the column V3 are
used to generate the output voltage V3.
[0088] FIG. 5 is a side view of a portion of the wiring harness 128
of FIG. 4, according to an embodiment. With reference to FIGS. 1-5
and the descriptions of FIGS. 1-4 above, a wire 136 is positioned
in the wiring slot 130. An exposed end of the wire 136 is in
contact with a busbar 142. The busbar 142 is electrically connected
to one of the terminals of one of the batteries. A screw 138 is
screwed into the screw hole 132. The end of the screw 138 contacts
a contact member 140. As the screw 138 is screwed further into the
screw hole and 32, the end of the screw 138 forces the contact
member 142 pressed downward on the wire 136. The downward pressure
on the wire 136 forces the wire 136 into stable electrical contact
with the busbar 142.
[0089] In one embodiment, the control circuitry 110 can force the
voltage combination circuitry to generate only one of the output
voltages V1-V3. In this case, the control circuitry 110 controls
one or more switches 144 that decouple the busbars 142 for the
deselected output voltages from the terminals of the batteries. The
result is that only the busbars 142 associated with the selected
output voltage will be electrically connected to the terminals of
the batteries, thereby ensuring that only the selected output
voltage will be generated by the voltage combination circuitry
106.
[0090] FIG. 6 is an illustration of a power cell module 102,
according to an embodiment. With reference to FIGS. 1-6 and the
descriptions of FIGS. 1-5 above, the power cell module 102 includes
a casing 122. The casing 122 houses the batteries 104a-104d, the
voltage combination circuitry 106, the control circuitry 110, the
sensors 116, the multi-voltage bus 108, and other internal
components of the power cell module 102.
[0091] In one embodiment, the casing 122 is formed of a durable
material that can withstand the weight of several power cell module
stacked on top of it. The material of the casing is also selected
to withstand portable use of the power cell module 102. The casing
122 can include a hard and durable plastic, according to an
embodiment.
[0092] In one embodiment, the inter-module multi-voltage bus
connectors 112 are positioned on the top surface of the power cell
module 102. Though not shown in FIG. 6, inter-module multi-voltage
bus connectors 112 are also positioned on a bottom surface of the
power cell module 102.
[0093] In one embodiment, when a power cell module is stacked on
top of the power cell module 102, the inter-module multi-voltage
bus connectors 112 on the top surface of the power cell module 102
connect with inter-module multi-voltage bus connectors on a bottom
surface of the other power cell module. The inter-module
multi-voltage bus connectors 112 ensure a secure electrical
connection of the voltage lines of the output voltages of the
multi-voltage bus 108 of each of the power cell modules, forming a
collective multi-voltage bus from all of the power cell modules in
a stack. Additionally, though not shown, inter-module multi-voltage
bus connectors 112 can also be positioned on lateral surfaces of
the power cell module 102 to facilitate stacking or connecting
power cell modules laterally as well as vertically.
[0094] In one embodiment, the inter-module multi-voltage bus
connectors 112 can include Anderson connectors. Additionally, or
alternatively, the inter-module multi-voltage bus connectors 112
can include other types of electrical connectors. Each inter-module
multi-voltage bus connector 112 can include a positive and a
negative terminal for the corresponding output voltage. In one
embodiment, the inter-module multi-voltage bus connectors 112 can
also include fasteners that securely fasten power cell module 102
to the power cell module that is placed on top of the power cell
module 102, or on top of which the power cell module 102 is placed,
as the case may be.
[0095] In one embodiment, the power cell module 102 also includes
fasteners 124 on the top and bottom surfaces of the power cell
module 102. The fasteners 124 can assist in fastening the power
cell module 102 to a power cell module placed on top of the power
cell module 102 the fasteners 124 can assist in fastening the power
cell module to a power cell module placed on the bottom of the
power cell module 102.
[0096] In one embodiment, the power cell module 102 also includes
user power outputs 114 on a front face of the power cell module
102. User power outputs 114 can also be positioned on other faces
of the power cell module 102. Users can connect electronic
appliances to the user power outputs 114 in order to power
electronic appliances with the power cell module 102, or with a
stack of power cell modules.
[0097] In one embodiment, the power cell module 102 can also
include user input devices, not shown in FIG. 6. The user input
devices can enable the user to input commands or otherwise control
features of the power cell module 102. The user input devices can
include buttons, switches, sliders, knobs, keypads, touchscreens,
or other devices by which users can input commands or control
features of the power cell module 102. In one embodiment, the user
input devices include a power button that enables the user to turn
the power cell module 102 on or off.
[0098] In one embodiment, the power cell module can also include
data ports, not shown in FIG. 6. The data ports can include
connectors for reading data from or writing data to a memory within
the power cell module 102.
[0099] In one embodiment, the power cell module 102 includes a
display 118. The display 118 can display text, images, or
animations. The user can read or view the text, images, or
animations displayed by the display 118.
[0100] Those of skill in the art will recognize, in light of the
present disclosure, that the power cell module in accordance with
principles of the present disclosure can have other shapes and
configurations than that which is shown in FIG. 6, without
departing from the scope of the present disclosure.
[0101] FIG. 7 illustrates a energy storage and supply system 100
including a bank of power cell modules 102a-102c, according to one
embodiment. With reference to FIGS. 1-7 and the descriptions of
FIGS. 1-6 above, FIG. 7 illustrates three power cell modules
102a-102c. However, more or fewer power cell modules can be
connected in a bank of power cell modules in accordance with
principles of the present disclosure.
[0102] In one embodiment, each power cell module the bank of power
cell modules is connected in such a manner that a collective
multi-voltage bus 108 is formed. The collective multi-voltage bus
108 includes a voltage line for each output voltage V1-V3. The
collective multi-voltage bus 108 simultaneously carries each of the
output voltages V1-V3.
[0103] In one embodiment, when an electronic appliance is connected
to one of the user power outputs 114 of one of the power cell
modules 102a-102c, power is provided to the electronic appliance
from each of the power cell modules 102a-102c. The voltage lines of
the multi-voltage bus 108 are shown as dashed lines internal to the
casings 122a-122c of the power cell modules 102a-102c. While each
output voltage is shown as having a single line, in practice, each
output voltage has both a positive and a negative line defining the
output voltage.
[0104] In one embodiment, each power cell in the system 100 is
substantially identical, having the same user power outputs 114,
the same display 118, and possibly other identical features such as
user inputs and data ports. In this case, power can be supplied by
plugging an electronic appliance into the user power outputs 114 of
any of the connected power cell modules 102a-102c. Alternatively,
one of the power cell modules can act as a master to the other
power cell modules in the stack. In this case, the electronic
appliances are connected to the user power outputs 114 of the
master power cell module. The master power cell module can be the
top power cell module, as one example, or the bottom power cell
module, as another example.
[0105] In one embodiment, the power cell modules 102a-102c are not
identical to each other. Instead, some power cell modules may have
more or fewer features, different arrangements of components,
different numbers of components, different sizes, different power
storage and supply capacities, or other types of differences. In
this case, the inter-module multi-voltage bus connectors 112 still
ensure that each power cell module 102a-102c joins the
multi-voltage bus 108. In one embodiment, one of the multi-voltage
power cells is a controlling or master multi-voltage power cell
having additional features compared to the other power cell modules
in the stack. Some power cell modules in the stack may be
relatively featureless in that they do not have user power outputs
114 and are only used to connected into the stack to provide
additional energy capacity to the system 100. Thus, the stack may
include one or master or controlling power cell modules, and one or
more simple or slave power cell modules that serve only to provide
additional capacity the system 100, according to one
embodiment.
[0106] FIG. 8 is an illustration of an energy storage and supply
system 100 including a bank of power cell modules 102a-102d,
according to one embodiment. With reference to FIGS. 1-8 and the
descriptions of FIGS. 1-7 above, the power cell modules 102a-102d
provide power to an electronic appliance 150.
[0107] In one embodiment, the bank of power cell modules 102a-102d
provides power to multiple electronic appliances 150. For example,
the bank of power cell modules can be configured to provide
electricity to an entire home when the municipal power grid fails.
In this case, the electronic appliances 150 can include lights,
washing machines, dishwashers, computers, televisions, set-top
boxes, DVD players, clothes dryers, ovens, toasters, garage door
openers, videogame consoles, microwave ovens, or anything else in a
home that typically receives power from the municipal power grid.
The larger the number of power cell modules in the bank, the larger
the capacity of the system 100 is to provide electricity to the
home. More power cell modules means that a given appliance can be
powered for a longer time, or that more electronic appliances can
be powered for a particular amount of time.
[0108] In one embodiment, the bank of power cell modules 102a-102d
is located at a business and is configured to provide electricity
to electronic appliances at the business location.
[0109] In one embodiment, the bank of power cell modules is
portable system that be taken to various locations to provide
electricity to electronic appliances 150. For example, the bank of
power cell modules 102a-102d can be taken camping, can be taken
outdoors to power outdoor yard equipment or power tools, or can be
taken to outdoor gatherings such as barbecues or parties to power
electronic equipment.
[0110] In one embodiment, the energy storage and supply system 100
includes one or more alternate power sources 152. The one or more
alternate power sources 152 can be coupled to the bank of power
cell modules to provide power to the power cell modules or to be
joined with the power cell modules in providing power to one or
more electronic appliances.
[0111] In one embodiment, the power cell modules may include a
charging bus. When the alternate power source 152 is connected to a
charging connection of one of the power cell modules 102a-102d, the
alternate power source 152 is connected to a charging bus that
enables the alternate power source 152 to charge the batteries
within each of the power cell modules 102a-102d.
[0112] In one embodiment, the alternate power source 152 can
provide power to the multi-voltage bus 108. In this way, the
alternate power source 152 supplements the power provided by the
power cell modules 102a-102d in powering the electronic appliances
150. Additionally, or alternatively, the alternate power source 102
can power the electronic appliances 150 in parallel to the power
cell modules 102.
[0113] In one embodiment, when the alternate power source 152 is
connected into one of the power cell modules 102a-102d, the power
cell module converts the voltage provided by the action power
source 150 to the output voltages carried by the multi-voltage bus
108. These output voltages generated from the alternate power
source 152 are connected to the corresponding lines of the
multi-voltage bus 108 so that the alternate power source 152 can
supplement the power provided to electronic appliances 150.
Accordingly, the power cell modules 102a-102d can include dedicated
ports for receiving energy from alternate power sources 152 to
either charge one or more of the power cell modules or to join in
the multi-voltage bus 108.
[0114] In one embodiment, the alternate power source 152 includes a
generator. The generator can be a conventional combustion generator
that generates electricity by combusting a fossil fuel in order to
provide backup power to a location when the municipal power grid
fails, or for other situations. The generator can be used to charge
the power cell modules 102a-102d, or to supplement the power
provided by the power cell modules 102a-102d. Utilization of a
combustion fuel-based system for some portion of power output or
energy storage effectively creates a "hybrid" system. Power may
flow in a serialized manner or in parallel to the modules in their
operation, depending on the system, the application and the
component modules.
[0115] In one embodiment, the alternate power source 152 includes
one or more of solar panels, wind turbines, hydropower generators,
flywheels, batteries, or super capacitors. All of these power
sources can be used to charge the power cell modules or to
supplement the energy provided by the modular powers.
[0116] In one embodiment, the alternate power source 152 is the
municipal grid. When the municipal grid is functioning properly and
the bank of power cells are connected to municipal grid, the
municipal power grid recharges the batteries within the power cell
modules 102a-102d.
[0117] In one embodiment, the system can be plugged into a standard
wall outlet of a house when the municipal power grid is interrupted
and is not supplying power. A power cord can be plugged into the
wall outlet from one of the power cell modules. The power cell
module converts one of the DC output voltages from the
multi-voltage bus into an AC voltage having the correct frequency
and amplitude for the wall outlet. The AC voltage is then supplied
to the wall outlet. All of the wall outlets that are on the same
circuit can now be powered by the AC voltage supplied from the
power cell module or bank of power cell modules. Before doing this,
the user will need to access the circuit box and trip the circuit
breaker to that circuit so that if the municipal power grid comes
back online there will not be a short circuit. The power cell
module can include protective circuitry to protect the power cell
module in the event of a short circuit. The power can be supplied
via a bank of power cell modules.
[0118] FIG. 9 is an illustration of an energy storage and supply
system 100, according to an embodiment. With reference to FIGS.
1-10 and the descriptions of FIGS. 1-8 above, the system 100
includes a plurality of power cell modules 102a-102g. The power
cell modules 102a-102g. are connected in the bank such that they
collectively provide power to one or more electronic appliances 150
as described previously.
[0119] In one embodiment, power cell modules can be removed from a
bank of power cells without interrupting the power provided by the
bank of power cells to the electronic appliances 150. This is due
in part to the multi-voltage bus that receives power from all of
the power cell modules connected in a bank of power cell modules.
Removing one or more power cell modules from the bank of power cell
modules does not interrupt the voltage provided by the
multi-voltage bus. Thus, the power provided to the electronic
appliances 150 is not interrupted when one or more of the power
cell modules are removed from the bank of power cell modules.
Furthermore, the inter-module multi-voltage bus connectors 112 are
configured such that the user can easily detach one or more of the
power cell modules without the risk of receiving an electrical
shock. The power cell modules may include decoupling switches or
latches that the couple the power cell modules from the collective
multi-voltage bus when the user operates the state decoupling
switches or latches. The user may then freely remove the desired
power cell modules from the bank of power cell modules.
[0120] In one embodiment, the electronic appliances 150 were being
powered by the power cell modules 102a-102j. when a user 153
detached the power cell modules 102f and 102g from the bank of
power cell modules. The user 153 connects an electronic yardwork
tool 154 to the power cell modules 102g. The power cell modules
102f and 102g collectively power the electronic yardwork tool 154.
The power cell modules 102f and 102g can be conveniently placed in
a backpack worn by the user 153. The power supplied to the
electronic appliances 150 is not interrupted when the user removes
the power cell modules 102g and 102g.
[0121] In one embodiment, because the module or system can be made
up of one or more modules the system 100 is an advantageous design;
holistically, situationally, economically, sustainably, and with a
more utilitarian approach than any typical systems. The system 100
has the advantage of scaling up or down depending on the specific
application.
[0122] In one embodiment, the system 100 provides a plurality of
energy and power cell modules comprised of a transformative power
coupling bus, or multi-voltage bus, wherein the addition of any
module into the system fundamentally changes the nature and
functionality of the system as a whole as well as the modular
components that make up the system. While each independent module
serves its own function or functions with features that may be
specific or shared across groups and families of similar or
dissimilar modules, when combined with one or more modules a new
system is created that provides greater features and function than
each of the modules would have independently.
[0123] In one example, consumers can purchase batteries, but they
will not be the versatile and scalable system provided in
accordance with the present disclosure. The hurdle of being a
battery expert limits the general population from accessing power
remotely or limits them to just generators. The modular system
described in accordance with principles of the present disclosure
does not need to be identified at the initial purchase. Consumers
can mix and match and purchase power cell systems and modules over
several purchases, making a system ideal for each unique
application or deployment.
[0124] In one embodiment, the system 100 utilizes energy storage
and generation technologies coupled with power output devices and
systems including but not limited to the following: batteries
including various chemistries and configurations, capacitors, solar
panels, thermal heat capture devices, wind and/or water turbines
and wheels, direct DC input from motors or combustion engines
linked to DC generating alternators; integrated circuits,
transistors, and transformers, that may convert the stored or
generated energy into DC or AC power at various voltages and
frequencies; electronics intended to drive magnetic audio devices,
such as speakers, monitors, tweeters; thermocoupling devices to
generate or reduce heat; photon-emitting electromechanical and
direct electrical photon emitting devices such as LEDs and the
drivers to power similar devices. In one embodiment, the act of
connecting the power cell modules creates a power system wherein
the system's sum is greater than the individual modules. In one
embodiment, the system 100 designed to be user friendly so anyone
can take advantage of it. The components easily snap together.
There is no need for specific knowledge in electricity. Unlike
other electrical systems, the system 100 can be easily used by
anyone. This is done by simplifying the user interface to something
as easy as using a power outlet in your home. Inverters, chargers,
controllers, and everything are internal to the system.
[0125] In one embodiment, the modules and the system are capable of
supporting non-stackable components, either made by a same
manufacturer or by disparate manufacturers and provides clear
industry standard connections to assist. This is done by using
industry standard plugs and connectors. In one embodiment, there
are no proprietary connectors on the system.
[0126] In one embodiment, the system eliminates the need for the
end user to understand power systems, proper wiring; parallel or
series connection, pairing correct voltages, balancing uneven
potential energies across storage and generation components and
systems. The system also protects the user from accidents that may
result in a failed attempt to wire other power and energy
devices.
[0127] In one embodiment, the system uses many available
components. It is the use and arrangement of these components that
has not be done in this manner and not been done to create a
battery module with multiple voltages let alone a system of various
modules that are now enabled because of the invention, and can be
done so without the use of switching ICs, or other power conversion
components that only add cost, and energy loss. A traditional
battery will have a set amount of energy with a set voltage output,
it may be comprised of multiple cells arranged together but the
output and interaction remain the same. This system allows for
simple methods for multiple energy levels and voltages depending on
the specific application. This system solves many different
portable power problems within one system. Different voltages and
energy levels can easily be selected. This is done by a unique
wiring connection system inside the casing of the power cell
module. The battery case has 4 or more separate batteries inside
it. If a higher voltage is needed, select batteries are wired in
series. If a lower voltage is needed the wiring configuration would
be wired in parallel. In one embodiment, the selection of voltage
is safely decided on the outside of the case with a manual selector
switch that will change the wiring architecture inside the
case.
[0128] In one embodiment, the system provides information to the
user about the state of the modules and the system. Independent
modules may also display relevant information regarding the state
or condition of the module. In some embodiments, the information
systems may be capable of supporting some of the following while
not being limited to wired (canbus, SCADA), wi-fi, radio, mobile
(cellular, ZigBee, Bluetooth). The easiest option would be to plug
a cellular air card to the battery through the USB port. This would
allow the system to be uploaded to any cloud database or Internet
of Things database. The system would be capable of incorporating
these communication protocols to make for integrated TOT power
devices and remote monitoring.
[0129] In one embodiment, modules with more energy may be safely
added during operation or in a powered off setting. Modules may be
safely removed during operation or in a powered off setting. No
wires are touched. No safety equipment is required to add or remove
modules. It is as simple as unlatching the module and lifting the
top from the bottom. The voltages and the connections used mean
this can be done safely and per code even when powered up.
[0130] In one embodiment, modules from a small system powering a
light, speaker, television, recharging a mobile phone can be used
together to provide the energy to power larger appliances, and in
turn can be used with larger modules intended to power multiple
large appliances can be used together with similar or smaller
units.
[0131] In one embodiment, power cell modules can be used
independently to provide direct DC power to handheld or fixed power
requirements/devices. These modules can in some instances be
mounted to backpack or similar personal harness to allow the user
to power DC devices while maintaining the use of their hands. Such
a harness or backpack could also support an energy or battery
module that is also connected to another power generation or output
device. Such a power output device which is not limited to, but may
provide AC power if connected to an energy or battery module, would
be capable of powering a multitude of household appliances. This
apparatus would thereby make these household appliances operate
beyond their standard constraints of the length of a cord, and
therefore transforming the nature of these appliances from grid
tethered to mobile. A power module, and perhaps, a control/head
unit would be attached to a backpack assembly. This will free up
both hands but allow the battery power to be there for immediate
access. No need for any cords.
[0132] In one embodiment, some modules may be DC power modules and
others may be AC power modules.
[0133] In one embodiment, a power cell module, and thereby the
system it may be connected to, with either event driven or remotely
"triggered" operation is described: The event might be a
temperature threshold, for example if the module detects that the
temperature it is monitoring has changed such that it triggers the
module to begin an action or series of actions. Unlike a typical
combustion fueled generator the system may use very little to no
energy "waiting" for an event to occur at which point energy can
flow to the module as it is needed, not wasting energy. The system
could also utilize a remote start function to trigger a generator,
for many purposes. Remote start switches are readily available in
the market. Installing one of these with our battery systems will
allow us to install our systems in remote applications with
intermittent power draw. The switch would allow power to be
discharged only exactly when it is called upon.
[0134] In one embodiment, a power output module is capable of
delivering the power from different modules composed of different
chemistries, fuel sources, and in series with power capture
technologies. A system that can utilize two or more different types
of chemistries would be a system that is called `chemistry
agnostic` to those with industry knowledge, a power module may or
may not have the ability to utilize energy modules of one or more
different type of chemistry, but also fuel composition, and not
only stored "potential" energy resources but real-time captured or
captured stored and then transmitted energy.
[0135] In one embodiment, the modules may provide multiple voltages
in various currents and frequencies. Traditionally multiple
voltages can be accomplished utilizing integrated circuits to
switch voltage or other electromechanical or electrochemical
components to transform voltage, similarly with the current and if
required, frequency. The modules utilize an advanced connection
scheme called the multi-voltage bus. In one embodiment, the
multi-voltage bus is present on all modules and provides the
primary means for modules to electrically connect to each other and
is one of several mechanisms that physically guide the user to
correctly orient the module to another for the desired output
voltage.
[0136] In one embodiment, there are many ways to achieve multiple
voltages, one method is detailed in a wiring schematic showing 4
traditional batteries arranged in 3 configurations with 3 different
voltages available on the multi-voltage bus. By arranging the
traditional batteries in this configuration, other modules
connected to the battery may provide only one operating voltage,
but the energy is thus transformed throughout the entirety of the
system.
[0137] In one embodiment, a power cell module may utilize one or
all of the multi-voltage bus lines available depending on the
purpose of the module. Regardless of the module utilizing one or
all of the multi-voltage bus lines subsequent modules can
interconnect and electrical flow between modules is maintained. In
one embodiment, a first power cell module is capable of utilizing
all multi-voltage lines. Second, third, and fourth power cell
modules are energy storage modules each with different total
capacity providing access to energy on each line of the
multi-voltage bus without the need for (although it may utilize)
transformers, switching circuits or similar components.
[0138] In one embodiment, a power capture module can be added
anywhere to the system. The power capture module can be a "solar"
capture device, whose panels produce a voltage that fits
multi-voltage bus line 3. While the power capture module may be
capable of providing various voltages, utilizing such switching
electronics described above, and it may or may not need these to
deliver at least one voltage compatible with the multi-voltage bus,
it is more common, simple, and cost effective for the solar system
to provide one voltage out, in this example line 3 on the
multi-voltage bus line. Because there are power cell modules
capable of accepting the multi-voltage bus line the power generated
from the power capture module transformed through the system to
provide power on all the multi-voltage bus lines, the electrons
that went out on multi-voltage bus line 3 are now capable of
flowing through all lines without requiring the common transforming
technologies.
[0139] In one embodiment, the multi-voltage bus may employ several
means by which to detect or become `aware` of operational
parameters of the various multi-voltage bus lines, allowing a
module with a smart multi-voltage bus to drop in or out. The smart
multi-voltage bus makes it so the electron flow may continue
uninterrupted between modules even if the module with a smart
multi-voltage bus determines it should drop out of one or all of
the possible multi-voltage bus lines. There may or may not be the
availability of an override trigger either physical or electrically
controlled allowing a user to momentarily reset the Smart
multi-voltage bus.
[0140] In one embodiment, electrical protection between modules and
across the system for components, the user and the environmental
safety can be important. Safety components such as fuses, breakers,
shunts and diodes may be used to buffer and protect the module and
its components from unplanned events internal or external.
[0141] There may be additional function achieved when multiple
modules are capable of sharing one or more of the multi-voltage bus
lines in parallel and one or more multi-voltage bus lines in
series. In one embodiment, the multi-voltage bus line system may
support multiplexing one or more lines in a series connection,
adding the voltage between modules. This serial multiplexing
adjusts the physical connection between modules operating on the
multi-voltage bus. The physical shift can occur in multiple ways,
exclusively within the electro-mechanics, outside of the
multi-voltage bus mechanics or a combination of the two. This
serial connection can be achieved utilizing contactors, IGBTs, and
relays as one embodiment.
[0142] In one embodiment, the need for portable power can occur in
unplanned non-ideal events, many of which may take place during or
involving automotive or similar vehicular transportation. Power
cell modules may be capable of capturing power from a vehicle's
alternator or other cabin power system. The module may direct wire
or use standard connections such as the "cigarette" plug to capture
power. Depending on the wiring configuration this may occur when
the alternator or cabin power is running, or it may be on
constantly. Such a module or system if properly charged or
maintained by the vehicle's cabin power can provide energy back to
the vehicle if the vehicle's starter battery is not capable of
providing the necessary power. A module or system is thereby also
available to provide its other power and energy functions in an
emergency or non-emergency event.
[0143] In one embodiment, a power cell module or series of power
cell modules in a system, that may or may not be utilizing a
multiplexing serial multi-voltage bus, may have enough energy to
power a traction motor or integrated circuits and systems capable
to drive a motor. The module or modules would also be capable of
capturing energy through regenerative braking or other kinetic
energy harvesting methods.
[0144] In one embodiment, each module is enclosed in an external
shell to protect the components from common or if specifically
listed harsh environments. These enclosures may differ from one
another in appearance and function if so required of the enclosure.
The differing functions include but are not limited to some of the
following: easy opening to remove, expand, access parts or
components that may be inside or may adjust. The enclosure may
contain additional smaller modules that may or may not act
independently from the module itself and from the system but when
recombined in various, purposely designed methods and connections
result in new or similar features and functions.
[0145] In one embodiment, while the appearance of a power cell
module may or may not differ between similar or dissimilar modules
there are several features that may or may not be present in all or
some modules these include but are not limited to; devices to
securely and physically latch or connect one module to
another/depending on the module there may not be a means to latch
or secure other than the tension connection made with the
multi-voltage bus, a device or method to protect or to limit
physical damage to the module, system or specific components or
parts of the module or system, devices and methods to assist an
individual in aligning modules for simple and easy connection, a
device to carry/wheel or otherwise move a single or multiple
modules, a means and method to add a further
shell/housing/protective covering that may have a specific intended
purpose beyond the protections of the enclosure this purpose may be
for physical, aesthetic, transportational, electrical or another
function not described.
[0146] In one embodiment, while combustion fuels may have limited
appeal in what is generally envisioned and described often as a
`battery` based system, combustion fuels can be used in such a
stackable system. The motor or other means of converting the fuel
source into electrical energy may be triggered in some fashion,
remotely, event-driven or by other means of interaction. The energy
storage and supply system may have the ability to stop or restart
the process. Utilization of a combustion fuel-based system for some
portion of power output or energy storage effectively creates a
"hybrid" system. Power may flow in a serialized manner or in
parallel to the modules in their operation, depending on the
system, the application and the component modules.

batteries 104a-d are 12 V batteries and the output voltage V3 is 48
V. While FIG. 10B shows two sets of output terminals each
outputting the output voltage V3, in practice the output voltage V3

160a3-d3 all coupled to the batteries 104a-d. The 160a1-d1, the
relays 160a2-d2, and the relays 160a3-d3 can simultaneously provide
the output voltages V1, V2, and V3 to the multi-voltage bus 108.
Additionally, the control circuitry 110 can control the relays to
selectively provide any, all, or none of the voltages V1, V2, and
V3.
