Description
BACKGROUND
Technical Field
[0001] This disclosure relates to system cabinets, and in
particular, to a power cabinet.
Related Art
[0002] Power cabinets, as backup power supply systems or
electricity recycle systems, are widely applied in many electrical
fields.
[0003] An existing power cabinet generally includes a cabinet body
having a housing and a battery module installed or fixed in the
cabinet body. When the power cabinet is produced, the cabinet body
is first produced, and then the battery module is inserted into the
cabinet body in a manner of pulling a drawer, for installation and
fixing. In the foregoing solution, in one aspect, the battery
module needs to be pushed into the cabinet body, and is then fixed
in another manner such as by using a screw. This increases
installation procedures and manual costs in an installation
process. In another aspect, cable wiring in the cabinet body is
messed up. Besides, cables and the cabinet body are customized
according to a quantity of battery modules, which is unhelpful for
extension and is inflexible in usage. In addition, production of
the cabinet body also requires costs and time.
SUMMARY
[0004] This disclosure aims to resolve at least one of the
foregoing technical problems to some extent, and provides a power
cabinet having a simple installation procedure, low costs, and tidy
wiring.
[0005] In view of this, this disclosure provides a power cabinet,
including: M modules, where the M modules are sequentially stacked
from top to bottom; N hot swappable components, configured to lead
out a power line and/or a signal line; and N locking apparatuses,
where a p.sup.th module and a (p+1).sup.th module are electrically
connected by using a p.sup.th hot swappable component, the p.sup.th
module and the (p+1).sup.th module are connected by using a
p.sup.th locking apparatus, M, N, and p are all integers,
M.gtoreq.3, N=M-1, 1.ltoreq.p.ltoreq.M-1, at least one of the M
modules is a battery management module, and remaining modules of
the M modules are battery modules.
[0006] In the power cabinet provided in this disclosure, a cabinet
body of a traditional power cabinet does not need to be customized,
the M modules are directly stacked from top to bottom to form the
cabinet body, the N locking apparatuses are used to assemble and
fix the modules, a battery module does not need to be installed and
fixed in the cabinet body, an installation procedure is simpler,
and costs required to produce the cabinet body are reduced.
Besides, the power cabinet provided in this disclosure may be
extended according to a requirement, and battery modules may be
increased. This is implemented very easily, and more layers may be
stacked. However, if the power cabinet having the cabinet body in
the prior art needs to be extended, the cabinet body needs to be
changed. This results in high costs and a complex procedure.
Besides, the N hot swappable components lead out the power line or
the signal line of the battery module from the battery module, and
electrically connect neighboring modules. This reduces cable use
complexity and facilitates installation, and cable wiring is tidy
and is safer.

DETAILED DESCRIPTION
[0028] The following describes embodiments of this disclosure in
detail. Examples of the embodiments are shown in the accompanying
drawings, and same or similar reference numerals throughout the
accompanying drawings indicate same or similar components or
components having same or similar functions. The following
embodiments described with reference to the accompanying drawings
are exemplary, aim to explain this disclosure, and shall not be
understood as limiting this disclosure.
[0029] In descriptions of this disclosure, it should be understood
that direction or position relationships indicated by terms such as
"length", "width", "thickness", "above", "below", "front", "back",
"left", "right", "vertical", "horizontal", "top", "bottom",
"inside", and "outside" are direction or position relationships
based on the accompanying drawings, and are used only for
conveniently describing this disclosure and simplifying
descriptions, instead of indicating or suggesting that a
represented apparatus or component needs to have a particular
direction or is constructed and operated in a particular direction,
and therefore shall not be understood as limiting this disclosure.
In addition, terms "first" and "second" are used only for
description purposes, and shall not be understood as indicating or
suggesting relative importance or implicitly indicating a quantity
of indicated technical features. Therefore, features modified by
"first" and "second" may explicitly or implicitly include one or
more features. In descriptions of this disclosure, "multiple" means
two or more, unless otherwise defined clearly and specifically.
[0030] In this disclosure, unless otherwise clearly specified and
defined, terms such as "installation", "interconnection",
"connection", and "fixing" shall be understood in a broad sense,
for example, may be a fixing connection, a detachable connection,
an integral connection, a mechanical connection, an electrical
connection, a direct connection, an indirect connection by using an
intermediate medium, and communication between interiors of two
components. A person of ordinary skill in the art may understand
specific meanings of the foregoing terms in this disclosure
according to a specific situation.
[0031] The power cabinet provided in this disclosure includes M
modules. The M modules may include a first module, a second module,
. . . , an (M-1).sup.th module, and an M.sup.th module. The first
module, the second module, . . . , the (M-1).sup.th module, and the
M.sup.th module are sequentially stacked from top to bottom. The
first module is located at the top, and the second module is
disposed below the first module. Similarly, a penultimate module is
the (M-1).sup.th module, and the M.sup.th module is located at the
bottom. In this disclosure, M may be any integer greater than or
equal to 3. For example, in FIG. 1, M is 10.
[0032] In this disclosure, to facilitate assembly and tidy
appearance of the entire power cabinet, the first module, the
second module, . . . , the (M-1).sup.th module, and the M.sup.th
module are generally all produced as modules having same
appearances and sizes. This can avoid distinguishing the modules in
an installation process, and any module may be directly used and
stacked without distinguishing whether the selected module
satisfies an installation requirement. In this way, assembly and
tidy appearance of the entire power cabinet can be desirably
controlled.
[0033] In the foregoing, the first module, the second module, . . .
, the (M-1).sup.th module, and the M.sup.th module are sequentially
stacked from top to bottom. In this disclosure, it indicates that
the first module, the second module, . . . , the (M-1).sup.th
module, and the M.sup.th module are directly stacked and
interconnected. The modules are not only interconnected but also in
communication connection with each other, including a power
connection and/or a signal connection, and the like. As can be
predicted, this disclosure provides a power cabinet formed by
stacking and interconnecting modules, and a person skilled in the
art may add a housing outside the power cabinet, or place the power
cabinet in another installation space based on this disclosure
without departing from the protection scope of this disclosure.
[0034] The power cabinet provided in this disclosure further
includes N hot swappable components used to lead out the power line
and/or the signal line. The N hot swappable components include a
first hot swappable component, . . . , and an N.sup.th hot
swappable component. N may be any integer greater than or equal to
2. Each hot swappable component includes a hot swappable female end
and a hot swappable male end. A person skilled in the art easily
understands that the power line and/or the signal line in each
module is led out to a hot swappable component corresponding to the
module, and then the power lines and/or the signal lines in two
neighboring modules are connected by using the hot swappable
component.
[0035] In an embodiment of this disclosure, a module of the power
cabinet may be a battery module, including a housing and a battery
pack disposed in the housing. The battery pack leads out a leading
wire, the leading wire is the power line and/or the signal line,
and the leading wire is connected to the hot swappable component
after passing through a line plate. Furthermore, the first hot
swappable component includes a first hot swappable female end and a
first hot swappable male end. Similarly, the N.sup.th hot swappable
component includes an N.sup.th hot swappable female end and an
N.sup.th hot swappable male end. In this disclosure, in any case,
battery modules used as the second module to the (M-1).sup.th
module except the first module and the M.sup.th module include two
hot swappable terminals. In this case, a positive pigtail and a
negative pigtail of the leading wire of the battery module
separately lead out to the two different hot swappable terminals.
Certainly, the foregoing configuration is only an embodiment of
this disclosure. In an actual solution, the first module and the
M.sup.th module may also include two hot swappable terminals, and a
specific structure is very easily understood by a person skilled in
the art. In an embodiment, all battery modules of the power cabinet
have same structures, a hot swappable female end is disposed above
each battery module, and a hot swappable male end is disposed below
each battery module. In this way, the power cabinet may be
assembled more easily, and extension of the power cabinet is better
facilitated.
[0036] The leading wire (the power line and/or the signal line) led
out from the battery pack is connected to the line plate, and the
line plate leads out an output line to electrically connect to a
hot swappable female end or a hot swappable male end above or below
the battery module, and to be led out by the hot swappable female
end or the hot swappable male end.
[0037] In the power cabinet, a p.sup.th module and a (p+1).sup.th
module are electrically connected by using a p.sup.th hot swappable
component, where p is an integer and 1.ltoreq.p.ltoreq.M-1. That
is, the first module and the second module are electrically
connected by using the first hot swappable component. That is, the
first hot swappable component is disposed between the first module
and the second module. In the power cabinet shown in FIG. 1, the
first hot swappable component is located between the first module
and the second module. The first hot swappable component implements
a communication and/or electrical connection between the first
module and the second module. Similarly, the power cabinet further
includes the second hot swappable component, . . . , and an (N-1)th
hot swappable component sequentially disposed from top to bottom.
The second hot swappable component is located between the second
module and the third module. Similarly, a person skilled in the art
may very easily understand locations, effects, and functions of the
hot swappable components. The (M-1).sup.th module and the M.sup.th
module of the power cabinet are electrically connected by using the
N.sup.th hot swappable component. That is, the N.sup.th hot
swappable component is disposed between the (M-1).sup.th module and
the M.sup.th module. The N.sup.th hot swappable component
implements a communication and/or electrical connection between the
(M-1).sup.th module and the M.sup.th module.
[0038] In the power cabinet, the first hot swappable component, . .
. , and the N.sup.th hot swappable component are used, so that the
first module, the second module, . . . , the (M-1).sup.th module,
and the M.sup.th module can implement a signal connection and/or an
electrical connection more orderly and easily. This can avoid
messed wiring in the cabinet body of the power cabinet in the prior
art, and improve wiring safety of the power cabinet.
[0039] In an embodiment, the power cabinet further includes N
locking apparatuses. Each locking apparatus may include a locking
female end and a locking male end, and N may be any integer greater

is the second module 12 in FIG. 1, the hot swappable male end 31 is
the first hot swappable male end, the protection bracket 81 is the
first protection bracket, and the locking male end 41 is the first
locking male end.
[0080] Besides, as shown in FIG. 4, based on FIG. 3, a hot
swappable female end 32, a protection groove 82, and a locking
female end 42 are disposed below the battery module. The battery
module may be any one of the second module to the tenth module in
FIG. 1. When the battery module is the second module in FIG. 1, the
hot swappable female end 32 is the second hot swappable female end,
the protection groove 82 is the second protection groove, and the
locking female end 42 is the second locking female end.
[0081] Similarly, in this disclosure, the battery modules are
sequentially disposed in FIG. 1, and all battery modules have same
shapes and designs, that is, all battery modules have same upper
sides and lower sides.
[0082] In addition, in the power cabinet shown in FIG. 1, the base
20 is disposed at the bottom. As shown in FIG. 5, a hot swappable
male end 31, a locking male end 41, and a protection bracket 81 are
disposed above the base 20. Based on the embodiment shown in FIG.
1, as shown in FIG. 5, the hot swappable male end 31 is a tenth hot
swappable male end, the locking male end 41 is a tenth locking male
end, and the protection bracket 81 is a tenth protection
bracket.
[0083] As shown in FIG. 1 to FIG. 4, in the embodiments, a handle
70 is further disposed on each module of the power cabinet, and the
handle 70 facilitates installation and usage of each module.
[0084] As shown in FIG. 2, the battery management module is
provided with a power interface 51 and a signal interface 52. The
power interface 51 is configured to lead out a positive electrode
and a negative electrode of the power cabinet, and the signal
interface 52 is configured to lead out a sampling line.
[0085] As shown in FIG. 6, an example in which wiring of the
battery module is led out to the hot swappable male end 31 is used
to describe composition and wiring of the battery module. A leading
wire 62 of a battery pack 63 is connected to a line plate 61, and
is connected to the hot swappable male end 31 by using the line
plate 61, to lead out a power line and/or a signal line in the
battery module to the hot swappable male end. Certainly, design of
a hot swappable female end is also similar to that shown in the
figure, and details are not described herein again.
