[0002] With the rapid development of the energy storage industry and the increasing demand for home energy storage batteries, the applications of energy storage batteries are becoming more diversified, with home energy storage being one example. For manufacturers of energy storage power batteries, continuous improvement in design is necessary. Currently available energy storage batteries have low energy capacity, do not meet the requirements for wall-mounted installation, have low waterproof ratings, and insufficient strength. The method of fixing multiple battery packs by stacking is simplistic, and when the number of stacked modules exceeds a certain limit, the strength requirements for the battery pack shell in the bottom area are high, easily leading to shell deformation and posing risks of compression and battery safety. The low waterproof rating of the shell limits its application to indoor environments and cannot meet outdoor needs; the multi-part design and assembly are complex and result in an unsightly appearance.

[0026] Example:

[0027] A wall-mounted energy storage battery pack includes a support frame 200; the support frame 200 includes a mounting bracket 210 for supporting a cell module 300 and a hanging bracket 220 perpendicular to the mounting bracket 210; in one embodiment, the mounting bracket 210 and the hanging bracket 220 are connected in an L-shape, which ensures support for the cell module 300 and facilitates wall-mounted installation; the mounting bracket 210 is mainly used to provide support for the cell module 300; since the mounting bracket 210 is ultimately located inside the outer casing 100, the mounting bracket 210 may include multiple hollow holes to facilitate heat dissipation and save costs and reduce weight; the hanging bracket 220 needs to be connected to the outer casing 100 to achieve a seal. In one embodiment, the hanging bracket 220 should typically include a plate-like structure to facilitate a sealed connection, and in this case, the weight of the hanging bracket 220 can also be reduced as much as possible.

[0028] In one embodiment, a plurality of battery cell modules 300 are stacked on the mounting frame 210. It should be noted that the stacking can be understood as a connection layer by layer, that is, the weight of the battery cell module 300 at the top will be transferred to the battery cell module 300 at the bottom. It can also be understood that the battery cell modules 300 are not directly connected when stacked, and the weight of the battery cell module 300 is transferred to the mounting frame 210 and will not act on the adjacent battery cell module 300. In this case, the battery cell module 300 can be prevented from being compressed, its safety can be improved, and the battery pack can achieve a larger capacity.

[0029] In one embodiment, a support spacing component 310 is provided between adjacent cell modules 300 and / or between a cell module 300 and a mounting frame 210. The support spacing component 310 can provide support and directly transfer the pressure to the mounting frame 210, thereby avoiding additional pressure on the lower cell module 300 when stacked. The support spacing component 310 provided between the cell module 300 and the mounting frame 210 can provide a better installation position for the cell module 300 and avoid the impact of the mounting frame 210 on the cell module 300. It can be understood that the mounting frame 210 itself is a structural support component, and the precision requirements during processing are not high. There may be protrusions in the weld area that have not been cleaned properly during welding, and the installation platform of the mounting frame 210 may not be flat. If the bracket is used to install the cell module 300 on it, there may be a risk of damage to the cell module 300. The support spacing component 310 can effectively avoid these problems. In one embodiment In this embodiment, the support spacing component 310 includes a first support block 311 disposed between the mounting frame 210 and the battery cell module 300; at least two first support blocks 311 are provided; a first pad 312 is provided between the first support blocks 311; the first pad 312 is at least one of an insulating layer, a thermally conductive layer, and a foam layer; the first pad 312 can provide an isolation layer between the battery cell module 300 and the mounting frame 210 to ensure the safety of the battery cell module 300, and the pad structure itself has a certain deformation capability to compensate for some defects on the surface of the mounting frame 210; in one embodiment, the first support block 311 is strip-shaped, and two first support blocks 311 are provided, which are respectively connected to the two sides of the bottom of the battery cell module 300; in one embodiment, a groove 301 is provided at the connection between the battery cell module 300 and the battery cell support block, so as to ensure that the spacing between the battery cell module 300 and the mounting frame 210 is as small as possible when they are spaced apart, thereby reducing the size in the height direction.

[0030] In one embodiment of this utility model, the battery cell module 300 is provided with a housing 100 that is sealed and connected to the support frame 200; the housing 100 is provided with a control circuit board 330 connected to the battery cell module 300; and the support frame 200 is connected to the wall-mounted assembly 400.

[0031] In one embodiment of this utility model, a reinforcing member 211 connects the mounting frame 210 and the hanging frame 220; the hanging frame 220 is provided with several crossbeams 221. The reinforcing member 211 can be a reinforcing plate or a reinforcing rib, both of which can achieve structural reinforcement when the mounting frame 210 and the hanging frame 220 are connected; when the reinforcing member 211 is a reinforcing plate, it can be... Figure 2 The triangular structure in it.

[0032] In one embodiment of this utility model, the support spacing component 310 includes a second support block 313 disposed between adjacent cell modules 300; at least two second support blocks 313 are provided; a second padding layer 314 is provided between the second support blocks 313; the second padding layer 314 is at least one of an insulating layer, a thermally conductive layer, and a foam layer. In this embodiment, the support spacing component 310 can effectively ensure the stacking arrangement between the cell modules 300 and avoid the cell modules 300 from bearing additional pressure. It can be understood that although the cell modules 300 are stacked, they are actually spaced apart and not directly connected, so there is no direct force transmission.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, two battery cell modules 300 are stacked on the mounting frame 210; one end of the second support block 313 is connected to a support member 315 for fixed connection with the mounting frame 210, and the other end is fixedly connected to a crossbeam 221 provided on the hanger 220, so that the second support blocks 313 are spaced apart on the battery cell modules 300 fixedly connected to the mounting frame 210. In this structure, the weight of the top battery cell module 300 is directly transferred to the mounting frame 210, thereby avoiding the influence on the lower battery cell modules 300; when more battery cell modules 300 are provided, this structure can also be used, which can be understood as stacking multiple second support blocks 313 and support members 315. In one embodiment, the support member 315 can be a plate-like structure or multiple support rods.

[0034] In one embodiment of this utility model, the control circuit board 330 is disposed on top of the battery cell module 300 furthest from the mounting bracket 210; the control circuit board 330 is spaced apart from the battery cell module 300 via a second connecting bracket 320; the control circuit board 330 is a BMS protection board. This spaced arrangement can reduce the impact of heat generated by the battery cell module 300; in another embodiment, the control circuit board 330 can also be disposed on the support member 315.

[0035] In one embodiment of the present invention, the outer shell 100 is sealed to the support frame 200 by a sealing ring 120; the mounting frame 210 is disposed in the accommodating space inside the outer shell 100; the outer shell 100 is sealed to the hanging bracket 220; and a connector 110 is provided on the outer shell 100.

[0036] In one embodiment of this utility model, the wall-mounted assembly 400 includes a first connecting frame 420 and a plurality of hanging parts 410 that are snapped into the first connecting frame 420; the hanging parts 410 are fixedly connected to the hanging bracket 220. In one embodiment, three hanging parts 410 are provided and arranged parallel to each other.

[0037] like Figure 4 As shown, in one embodiment of this utility model, the hanging member 410 includes a snap-fit ​​groove 411 and a clearance groove 412 located below the snap-fit ​​groove 411 and communicating with the snap-fit ​​groove 411; the top of the first connecting frame 420 is provided with a snap-fit ​​plate 421 that cooperates with the snap-fit ​​groove 411. The clearance groove 412 allows the hanging member 410 to be closer to the snap-fit ​​plate 421, when the snap-fit ​​plate 421 abuts against the inner wall of the clearance groove 412 ( Figure 4 When the middle relief groove 412 is located on the left side wall, the snap-fit ​​groove 411 and the snap-fit ​​plate 421 can be snapped together by moving the hanging piece 410 downward.

[0038] like Figure 4 As shown, in one embodiment of this utility model, the bottom of the hanging member 410 is provided with a limiting plate 413 extending away from the snap-fit ​​groove 411; the first connecting frame 420 is provided with a limiting hole 422 that cooperates with the limiting plate 413; when the snap-fit ​​groove 411 cooperates with the snap-fit ​​plate 421, it can limit the displacement of the top of the hanging member 410. By further increasing the cooperation between the limiting plate 413 and the limiting hole 422, the displacement of the bottom of the hanging member 410 can also be limited, achieving a better limiting effect and preventing the battery pack from detaching from the first connecting frame 420; the hanging member 410 is provided with a plurality of fixing holes 414; the snap-fit ​​plate 421 is provided with a through hole 423 that cooperates with the fixing hole 414 when the hanging member 410 is snapped with the first connecting frame 420; the hanging member 410 is fixedly connected to the first connecting frame 420 by a fixing screw 424 passing through the through hole 423 and threadedly connected to the fixing hole 414. In one embodiment, the size of the through hole 423 is larger than the size of the fixing hole 414, which facilitates the installation of the fixing screw 424.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
