Specific implementation

[0036] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be described clearly and completely below in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0037] As Figure 1 shown, one specific implementation of the battery module provided in the embodiment comprises: a cell group, an end plate 2 and a side plate.

[0038] Specifically, the battery cell group has a plurality of battery cells 1 arranged side by side; the end plate 2 has at least two end plates arranged at the two ends of the length direction of the battery cell group and covering the end face of the battery cell group; the side plate has a plurality of side plates arranged in parallel and spaced apart along the length direction of the battery cell group, and the two ends of the side plate are connected with the end plate 2. The end plate 2 has a first flange 3 and a second flange 4 extending away from the battery cell group and perpendicular to each other, the first flange 3 is parallel to the two side faces of the battery cell group, and the second flange 4 is parallel to the top face and the bottom face of the battery cell group, the first flange 3 has a first mounting hole 5 for passing through a fastener to connect with the side plate, and the first flange 3 or the second flange 4 has a second mounting hole 6 for passing through a fastener to connect with the box 15.

[0039] In this embodiment, the end plate 2 is arranged at the two ends of the length direction of the battery cell group and covers the end face, which can effectively protect the end of the battery cell group and prevent the battery cell 1 from being damaged by external force in this direction, and also helps to maintain the structural integrity of the battery cell group in the length direction. In order to connect the end plate 2 with the side plate and install the subsequent battery module, the end plate 2 is provided with a first flange 3 parallel to the two side faces of the battery cell group and a second flange 4 parallel to the top face and the bottom face of the battery cell group, the first flange 3 is provided with a first mounting hole 5 for connecting with the side plate, and the first flange 3 or the second flange 4 is provided with a second mounting hole 6 for connecting with the box 15. The side plate is arranged in parallel and spaced apart along the length direction of the battery cell group and the two ends are connected with the end plate 2, which provides additional support and protection for the battery cell group from the side, enhances the rigidity of the overall structure of the battery module, reduces the possibility of deformation or damage of the battery cell group due to lateral force, and through the combined design of the end plate 2 and the side plate, it provides a larger fixing and supporting effect while using fewer frames, solving the problem of large weight and high cost of the battery module frame in the prior art.

[0040] That is, as shown in Figure 1 , Figure 2 , whether it is fixed with the box 15 through the first mounting hole 5 on the first flange 3 or the second mounting hole 6 on the second flange 4, it belongs to the protection scope of this embodiment. The mounting hole arranged on different flanges can adjust the installation direction according to the needs in the later installation process.

[0041] It should be noted that this embodiment does not limit the fixed connection mode of the side plate and the end plate 2, because as long as it can be fixedly connected to form a stable frame structure, it can play a role in packaging and fixing the battery cell 1 module.

[0042] As shown in Figure 2 , Figure 3As shown, this is a specific implementation of the battery module provided in this embodiment. The side plate includes two upper side plates 7 and one lower side plate 8. The upper side plates 7 are attached to the top surface and side surface of the battery cell assembly, and the lower side plate 8 is attached to the bottom surface and side surface of the battery cell assembly. There are gaps between the two upper side plates 7 and between the upper side plate 7 and the lower side plate 8.

[0043] Specifically, the two upper side plates 7 are attached to the top and sides of the battery cell assembly, tightly wrapping the contact area of ​​multiple battery cells 1 within the assembly, providing structural support to the top of the battery cell assembly. The lower side plate 8 is attached to the bottom and both sides of the battery cell assembly, wrapping the bottom of the assembly and reducing the likelihood of the bottom of the battery cell assembly shifting due to gravity. The spacing design between the two upper side plates 7 and between the upper side plate 7 and the lower side plate 8 reduces the amount of material used without compromising protective performance, lowering costs, and also facilitates heat dissipation during operation, preventing problems such as performance degradation and shortened lifespan of the battery cells 1 due to heat accumulation.

[0044] like Figure 2 As shown, this is a specific implementation of the battery module provided in this embodiment. The lower side plate 8 has a web plate 9 that is attached to the bottom surface of the cell assembly. The web plate 9 has upwardly turned wing plates 10 on both sides, and the wing plates 10 are attached to the side surface of the cell assembly.

[0045] Specifically, the web plate 9 is attached to the bottom surface of the battery cell assembly, which can evenly distribute the weight and stabilize the position of the battery cell assembly. The wing plate 10 is attached to the side surface, which works with the web plate 9 to limit the horizontal swaying of the battery cell assembly, enhance the structural stability, and block the impact from the bottom and sides to protect the battery cell assembly.

[0046] Additionally, in other embodiments, such as Figure 1 As shown, the side plate can also be configured to include: two upper side plates 7 and two lower side plates 8. The upper side plates 7 are attached to the top and side surfaces of the battery cell assembly, and the lower side plates 8 are attached to the bottom and side surfaces of the battery cell assembly. The upper side plates 7 have a first bonding plate 13 and a second bonding plate 14 that are perpendicular to each other. The first bonding plate 13 is parallel to the side surface of the battery cell assembly, and the second bonding plate 14 is parallel to the top surface of the battery cell assembly. The two ends of the first bonding plate 13 are connected to the first flange 3 of the end plate 2 by fasteners. The lower side plates 8 have a third bonding plate 11 and a fourth bonding plate 12 that are perpendicular to each other. The third bonding plate 11 is parallel to the side surface of the battery cell assembly, and the fourth bonding plate 12 is parallel to the bottom surface of the battery cell assembly. The two ends of the third bonding plate 11 are connected to the first flange 3 of the end plate 2 by fasteners, and the two ends of the fourth bonding plate 12 are connected to the second flange 4 of the end plate 2 by fasteners. There are gaps between the two upper side plates 7, between the two lower side plates 8, and between the upper side plate 7 and the lower side plate 8.

[0047] That is to say, no matter whether the lower side plate 8 is two symmetrically arranged plates or one plate wrapping the two side surfaces and the bottom surface of the battery cell group at the same time, it belongs to the protection scope of the embodiment, that is, the lower side plate 8 can be connected with the end plate 2 to effectively fix the two side edges of the bottom of the battery module.

[0048] As shown in Figure 4 , the embodiment also provides an energy storage battery mounting device, which comprises a battery module and a mounting box, and the battery module is fixedly connected to the inside of the mounting box.

[0049] Specifically, the battery module is fixedly connected to the inside of the mounting box, thereby creating a relatively closed and stable working environment for the battery module. The mounting box can block dust, moisture, foreign matters and the like in the outside from entering the inside of the battery module, thereby avoiding damage of these impurities to the battery cell 1 and the like, and prolonging the service life of the battery module.

[0050] It should be noted that the embodiment does not limit the specific mounting direction of the battery module inside the box body 15, because the top surface of the battery module can face the opening direction of the box body 15, or can be arranged to face the inside side wall of the box body 15, and these mounting modes of the battery module all belong to the protection scope of the embodiment.

[0051] As shown in Figure 4 , a specific embodiment of the energy storage battery mounting device provided by the embodiment is shown, the mounting box comprises a box body 15 having an opening on one side, a plurality of battery cells 1 of the battery module are arranged in sequence in the box body 15, the inside side wall opposite to the opening in the box body 15 is provided with a cross beam 16, and the end plate 2 of the battery module is fixedly connected to the cross beam 16.

[0052] Specifically, the box body 15 is provided with an opening on one side, thereby facilitating the mounting and dismounting operation of the battery module and improving the work efficiency. The inside side wall opposite to the opening in the box body 15 is provided with the cross beam 16, thereby providing a stable mounting basis for the end plate 2 of the battery module. The battery module is fixed in the box body 15 by fasteners, thereby effectively preventing the displacement or shaking of the battery module in the box body 15, and further ensuring the reliable operation of the entire energy storage battery mounting device.

[0053] As shown in Figure 5 , a specific embodiment of the energy storage battery mounting device provided by the embodiment is shown, the inside bottom surface of the box body 15 is provided with a limiting block 17 for abutting against the side surface or the bottom surface of the battery module, and / or the cross beam 16 is provided with a limiting hole 18 for embedding a limiting member.

[0054] Specifically, the limiting block 17 on the inner bottom surface of the box 15 can accurately position the position of the battery module in the box 15, ensuring the accuracy and stability of the installation of the battery module. The fastener used by the limiting member, i.e., the first flange 3, is embedded in the limiting hole 18 to further limit the displacement of the fastener in the vertical direction. This double limiting design greatly improves the installation accuracy of the battery module in the box 15, ensuring the reliability of the entire energy storage battery installation device.

[0055] In addition, in other embodiments, as shown in Figure 6 The limiting hole 18 for limiting can be omitted, and when the battery module is installed in the box 15, the fastener for connecting the end plate 2 and the side plate and the reserved hole on the cross beam 16 are fixedly connected, which can also play a limiting and fixing role on the battery module.

[0056] As shown in Figure 4 A specific embodiment of the energy storage battery installation device provided by the present embodiment is shown. The box 15 has two groups of battery modules arranged side by side, and the electrode surfaces of the two groups of battery modules are arranged towards the two sides of the opening, respectively.

[0057] Specifically, arranging two groups of battery modules side by side in the box 15 increases the energy storage capacity. Arranging the electrode surfaces of the two groups of battery modules towards the two sides of the opening, respectively, can better balance the electric field distribution inside the device, reduce electric field interference, and improve the working efficiency and stability of the battery module.

[0058] In addition, in other embodiments, as shown in Figure 7 The electrode surfaces of the two groups of battery modules are arranged towards the opening direction. That is, the installation direction of the battery module in the installation device can be selected according to actual needs, improving the applicability of the energy storage battery installation device.

[0059] Working principle:

[0060] The battery module is composed of a cell group, an end plate 2, and a side plate. The plurality of cells 1 of the cell group are arranged side by side to meet the power demand. The end plate 2 is arranged at both ends of the cell group to protect the end portion and maintain the integrity of the structure. The side plate provides support and protection from the side to enhance the structural rigidity. The end plate 2 and the side plate cooperatively form a frame structure that reliably fixes and wraps the cell group. The energy storage battery installation device includes such a battery module and an installation box. The box 15 of the installation box is open on one side, and the inner cells 1 are stacked vertically. The box 15 is connected to the end plate 2 of the battery module through the cross beam 16. The bottom surface of the box 15 is provided with a limiting block 17, and the cross beam 16 is provided with a limiting hole 18. Two groups of battery modules can be installed side by side, and the electrode surfaces can be arranged in different directions. These designs ensure the performance of the battery while solving the problems of large frame weight and high cost in the prior art.

[0061] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the present application.
