[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-6 The stacked energy storage battery module structure shown includes a lower housing 1, and a single module 2 is provided on the top left and right sides of the lower housing 1.

[0031] Each of the single modules 2 includes two end plates 21 located at the top of the lower housing 1. The outer sides of the two end plates 21 are surrounded by packing straps 22. Several parallel batteries 23 are placed inside the packing straps 22. Each pair of adjacent batteries 23 are connected by connecting aluminum busbars 24 for connecting the batteries 23 in series.

[0032] A bridging aluminum busbar 3 is also provided on the rear side of the lower housing 1. The two ends of the bridging aluminum busbar 3 are respectively connected to the connecting aluminum busbar 24 on the two batteries 23 located on the rear side, for connecting the two single modules 2 in series.

[0033] The upper housing 4 is connected to the top of the lower housing 1 to accommodate two single modules 2, and together with the two single modules 2, they are assembled into an energy storage battery 23 module.

[0034] In one embodiment, the lower housing 1 is generally L-shaped, and tabs 5 are installed on both the left and right sides of the front wall. The two tabs 5 are respectively connected to the connecting aluminum busbars 24 on the two batteries 23 located on the front side for the output of the batteries 23. A data acquisition board 6 is also installed between the front side of one of the single modules 2 and the front wall of the lower housing 1 for collecting the power information of the battery 23 to meet the user's needs.

[0035] In one embodiment, the upper housing 4 is adapted to the lower housing 1 and is used to assemble with the lower housing 1 into a complete high-voltage box, which not only allows multiple batteries 23 to be installed together for use, but also protects the internal batteries 23.

[0036] In one embodiment, two wiring ports 7 are installed on the outer side of the front wall of the lower housing 1. The two wiring ports 7 are respectively connected to two tabs 5. The wiring ports 7 are positive and negative terminals, so that the battery 23 can be connected to the outside and the energy storage battery 23 module can be used normally.

[0037] In one embodiment, two sampling ports 8 are arranged side by side on the outer side of the front wall of the lower housing 1 to facilitate the user's use of the energy storage battery 23 module. A cooling fan 9 is also installed on the outer side of the front wall of the lower housing 1 between the two sampling ports 8 so that the heat generated by the battery 23 during use can be dissipated quickly, ensuring the service life of the energy storage battery 23 module.

[0038] The specific implementation method is as follows: During assembly, this utility model, such as... Figure 1-5 As shown, according to the installation requirements, the staff will arrange a certain number of batteries 23 in a longitudinal row on the bottom wall of the lower box 1. Then, they will use packing straps 22 to tie the batteries 23 in a uniform manner, and fix an end plate 21 on the outside of the batteries 23 located at the front and rear ends respectively. The batteries 23 are electrically connected to each other through connecting aluminum strips 24, thereby completing the assembly of a single module 2.

[0039] In the same manner described above, another single module 2 is assembled side by side on the other side of the bottom wall of the lower housing 1. Then, the two batteries 23 located behind the two single modules 2 are electrically connected using a cross-connecting aluminum busbar 3. Then, the housing 4 is installed on the top of the lower housing 1, so that the two single modules 2 are fixed in the high-voltage box assembled from the upper housing 4 and the lower housing 1, thereby producing an energy storage battery 23 module.

[0040] like Figure 6 As shown, when using the energy storage battery 23 module, several energy storage battery 23 modules can be stacked from bottom to top on the base plate 10. The base plate 10 is equipped with casters at the bottom for movement. When the number of energy storage battery 23 modules is greater than two, the adjacent energy storage battery 23 modules and the bottom energy storage battery 23 module are connected by connecting plates 11, so that multiple energy storage battery 23 modules can be stacked together for use. This assembly method is relatively simple, and the number of batteries 23 side by side and the number of energy storage battery 23 modules stacked vertically can be determined by the user according to the user's needs. The number of batteries 23 used is controllable, so the assembly of batteries 23 is not limited to one method. The battery 23 assembly method is flexible and versatile, which greatly reduces the space occupied by the batteries 23, can adapt to various complex installation environments, and is flexible in assembly and use, making it convenient for later maintenance and repair.

[0041] This implementation method specifically solves the problem that existing energy storage battery modules 23 in the prior art are all designed with standard size, have a single assembly method between batteries 23, occupy a large space volume, are easily restricted by the space environment during installation and use, have low flexibility, and are inconvenient to use.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
