The present disclosure claims priority to Chinese Patent Disclosure No. 202320644845.9, titled “POWER CABINET”, filed on Mar. 28, 2023 with the China National Intellectual Property Administration, which is incorporated herein by reference in its entirety
The present disclosure relates to the technical field of energy storage, and in particular to a stacked power supply modules.
Power supply modules are usually stacked vertically or horizontally. Since the power supply modules are electrically connected by means of hot-plugging, due to the influence of an external force, relative displacement inevitably occurs between the power supply modules during the stacking process and post-installation, which in turn leads to arcing or toppling. Therefore, it is required to limit or fix the power supply modules.
In the conventional fixing method, each power supply module needs to be fixed after the installation, which results in a complex fixing structure of the power supply modules and a cumbersome installation process.
In view of the above, a stacked power supply modules is provided according to the present disclosure, to solve the problems of complex fixing structure of power supply modules and cumbersome installation process in the conventional technology.
In order to achieve the above object, the following technical solutions are provided according to the present disclosure.
A stacked power supply modules is provided according to the present disclosure. The stacked power supply modules includes: at least two power supply modules, at least one first structural member and at least one second structural member, where
In an embodiment, each of the first structural members includes a concave-convex matched fitting structure or a shaft-hole matched fitting structure.
In an embodiment, a part, provided on a corresponding one of the power supply modules, of each of the first structural members is in an integral structure with the power supply module or in a discrete structure interconnected with the power supply module.

In an embodiment, the at least two power supply modules share all the second structural members;
In an embodiment, in a case that the at least two power supply modules share the second structural members, the second structural members are provided at one end or both ends of the power supply modules in a stacking direction, and/or,
In an embodiment, each of the second structural members is in an integral structure with a corresponding power supply module or in a discrete structure interconnected with the power supply module.
In an embodiment, the other end of each of the second structural members is mechanically connected to a support structure; and
In an embodiment, electrical connection between the at least two power supply modules includes: connection for electric energy flow and connection for signal flow;
In an embodiment, the at least two power supply modules are stacked in a vertical or horizontal direction.
The at least two power supply modules are stacked according to the present disclosure, and two adjacent power supply modules are limited and/or fixed in at least one direction through a corresponding first structural members, which in turn reduces the relative displacement between the power supply modules in a corresponding direction during installation, reduces the risk of arcing or tipping, improves safety while reduces the installation steps and reduces the complexity of a fixing structure. Furthermore, the power supply modules are limited and fixed in three directions by the first structural member together with the second structural member, thereby enabling the securing and fixation of the stacked power supply modules in the three directions after the installation and avoiding displacement after the installation.

Referring to
Each of the power supply modules 10 is a minimum power supply unit, which can be configured to perform the function of power supply storage and charging and discharging, such as battery packs.
The power supply modules 10 are stacked, and the number of the power supply modules 10 is at least two. In actual disclosure, the power supply modules 10 may be stacked in a vertical direction (as shown in
Furthermore, two adjacent power supply modules 10 are limited and/or fixed in at least one direction with each other through a corresponding first structural member 20. In actual disclosure, two adjacent power supply modules 10 may be limited and/or fixed in one or two directions through the corresponding first structural member 20, such as the X and/or Y directions of a three-dimensional coordinate system, i.e., at least one of a front-to-back direction and a left-to-right direction shown in
The power supply modules 10 are limited and/or fixed in at least one another direction through the second structural members 40, such as the Z-direction of the three-dimensional coordinate system, i.e., the vertical direction shown in
That is, the stacked power supply modules includes multiple power supply modules 10 and two structural members for limiting and fixing, the power supply modules 10 are placed in a stacking direction, two adjacent power supply modules 10 are limited and/or fixed in at least one direction through the corresponding first structural member 20, and all of the power supply modules 10 are limited and/or fixed through the second structural members 40.
During installation, the stacked power supply modules is firstly stacked quickly by means of the structural members, (i.e., the first structural member 20) provided on the power supply modules 10 for limiting and/or fixing in at least one direction. Then, after the last power supply module 10 has been stacked, the entire stacked power supply modules is secured and fixed by means of the second structural members 40, thereby realizing the secure fixation and easy installation through the second structural members 40.
In actual disclosure, the position-limiting between adjacent power supply modules 10 can be obtained in a corresponding direction through the corresponding first structural member 20, and all of the power supply modules 10 can be fixed through the second structural members 40. As shown in
In the stacked power supply modules according to the embodiment, the power supply modules 10 are limited and/or fixed to each other in at least one direction through the corresponding first structural member 20 during the installation, which in turn reduces the relative displacement between the power supply modules 10 in a corresponding direction during the installation, reduces the risk of arc pulling or tipping, improves safety while reduces the installation steps and reduces the complexity of a fixing structure. Furthermore, the power supply modules 10 are limited and fixed in three directions by the first structural members 20 together with the second structural members 40, thereby enabling the securing and fixing of the stacked power supply modules in the three directions in post-installation and avoiding displacement after the installation. In the above embodiment, it is not necessary to perform a process of fixation of the power supply module at every time of installation, thereby avoiding the problems of the complex fixing structure and the cumbersome installation process in the conventional technology.
On the basis of the above embodiment, in the stacked power supply modules according to the present embodiment, the first structural member 20 may be a concave-convex matched fitting structure.
It should be noted that the power supply modules 10 at two ends after being stacked may have the same structure as that of the power supply modules 10 in the middle (as shown in
and an lower surface of the power supply module 10 located at the bottom may be provided with a corresponding slot (as shown in
Alternatively, a part, provided on the power supply module 10, of the first structural member 20 may be in an integral structure with the corresponding power supply module 10, that is, the part is provided on a body of the power supply module 10; or, the part and the power supply module 10 may be discrete structures connected to each other, i.e., the part is provided separately.
In actual disclosure, at least two (shown as two in
On the basis of the above embodiments, in the stacked power supply modules according to the embodiment, the power supply modules 10 may share all of the second structural members 40, as shown in
Alternatively, the power supply modules 10 may be divided in groups and the power supply modules in one group share the corresponding second structural members 40. For example, every two or more power supply modules 10 are divided in one group together and share at least one corresponding second structural member 40. Alternatively, each of the power supply module 10 is provided with a corresponding second structural member 40, that is, each power supply module 10 may be provided with a corresponding second structural member 40 for fixing the power supply module 10. In this case, although the number of the second structural members 40 is relatively greater, the installation of the second structural members 40 can still be performed after all the power supply modules 10 have been stacked, which can still avoid the fact of having to fix each power supply module after the installation thereof, thereby avoiding the problems of the complex fixing structure and the cumbersome installation process in the conventional technology.
Specifically, in a case that the power supply modules 10 share the second structural members 40, the second structural members 40 may be provided at one end (as shown in
In addition, similar to the first structural member 20, the second structural member 40 may be in an integral structure with a corresponding one of the power supply modules 10, or, in a discrete structure connected to each other, depending on specific disclosure situations, which fall within the scope of protection of the present disclosure.
In actual disclosure, one end of the second structural member 40 is connected to the
corresponding power supply module 10 and the other end of the second structural member 40 may be mechanically connected to a support structure so as to limit and fix all the power supply modules 10. The support structure may be an external structural member, a wall, or the like, which is not limited here.
In the stacked power supply modules according to the embodiment, the power supply modules 10 are stacked in a horizontal or vertical direction, and two adjacent power supply modules 10 are limited or fixed in one or two directions through the first structural members 20. The second structural member 40 is provided on the outermost power supply module 10 of the stacked power supply modules so as to limit and fix all the power supply modules 10 in a second and/or third direction. In other words, the power supply modules 10 can be limited and fixed in three directions through the second structural members 40 together with the first structural members 20.
On the basis of the above embodiments, electrical connection between the power supply modules 10 in the stacked power supply modules according to the present embodiment includes: connection for electric energy flow and connection for signal flow.
Referring specifically to
It should be noted that end surfaces of the power supply modules 10 at two ends after being stacked, such as the upper surface of the top power supply module 10 and the lower surface of the bottom power supply module 10 when being stacked vertically, can be not provided with the corresponding electrical connection interface structural member 30, or, a corresponding electrical connection cover plate may be used to form a corresponding electric path between the power supply modules 10, which is not limited, depending on specific disclosure situations.
In actual disclosure, the electrical connection between the power supply modules 10 may be achieved by means of hot-plugging or cold-plugging, depending on disclosure situations, which fall within the scope of protection of the present disclosure.
Alternatively, the electrical connection between the power supply modules 10 may be sequential, i.e., adjacent power supply modules 10 are electrically connected to each other. For example, a first power supply module 10 is electrically connected to a second power supply module 10, and the second power supply module 10 is electrically connected to a third power supply module 10. Alternatively, the power supply modules 10 may be electrically connected in a spanning manner, i.e., the power supply modules are electrically connected at intervals, for example, the first power supply module 10 is electrically connected to the third power supply module 10, and the second power supply module 10 is electrically connected to a fourth power supply module 10. It is sufficient to provide each of the power supply modules 10 with a corresponding electrical connection interface structural member, which is not limited here and may be determined according to actual disclosure situations.
Some specific examples of the electrical connection between the power supply modules 10 are provided in this embodiment, which are not limited. It is sufficient to realize the connection of the energy flow and the signal flow between the power supply modules 10, which fall within the scope of protection of the present disclosure.
By means of the above principles, the stacked power supply modules enables the structural connection and the electrical connection between the power supply modules 10 to enable to perform corresponding storage function as well as charging and discharging functions. Furthermore, the module structure of the stacked power supply modules is simplified and the waterproofing requirements are significantly reduced. In addition, the stacked power supply modules have fewer fixing connection points for module installation compared to the conventional technology, allowing for reliable connection and fewer installation steps.
