[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] Please see Figure 1 and Figure 2 An energy storage battery module 10 includes: a first housing 100, a second housing 200, a battery cell 300, an integrated board 400, and a busbar 500. The first housing 100 is connected to the second housing 200. The battery cell 300 is disposed between the first housing 100 and the second housing 200. The integrated board 400 is connected to the side of the first housing 100 away from the battery cell 300. The busbar 500 is connected to the electrodes of the battery cell 300 and the integrated board 400 respectively.

[0024] It should be noted that the first housing 100 is connected to the second housing 200, thereby fixing the battery cell 300 between the two housings. The integrated board 400 is connected to the side of the first housing 100 away from the battery cell 300, facilitating manual installation of the integrated board 400. The area of ​​the side of the first housing 100 away from the battery cell 300 is larger than the area of ​​the end of the battery cell, meeting the installation requirements of electronic components. The integrated board 400 is fixed to the first housing 100 and integrates protection, inverter, and MPPT functions to ensure the safe and efficient operation of the battery module 10. By using busbars to connect the battery cell 300 to the integrated board 400, a reliable fixing structure is formed between the battery cell 300 and the integrated board 400. This fixing structure reduces the number of busbars used to fix the battery cell 300, improves the space utilization within the battery module 10, and increases the energy density of the battery module 10. At the same time, the reduced number and size of busbars can reduce the complexity of battery module 10 assembly and facilitate manual installation of battery module 10.

[0025] Please refer to it again. Figure 1 In one embodiment, the first housing 100 includes a first support plate 110 and two first connecting plates 120, which are respectively disposed on both sides of the first support plate 110. The first connecting plate 120 is provided with a first connecting portion 121. The second housing 200 includes a second support plate 210 and two second connecting plates 220, which are respectively disposed on both sides of the second support plate 210. The second connecting plate 220 is provided with a second connecting portion 221. The first connecting portion 121 and the second connecting portion 221 are connected by fasteners. The fastener connection method has the characteristics of high reliability and easy disassembly, which facilitates manual disassembly of the first housing 100 and the second housing 200, and further facilitates manual maintenance of the battery module 10. At the same time, the first connecting plate 120 and the second connecting plate 220 work together to provide support for the battery cell 300, and prevent the first support plate 110 and the second support plate 210 from squeezing the battery cell 300.

[0026] Please refer to it again. Figure 1 In one embodiment, the first housing 100 is provided with a plurality of first limiting parts 130, and the second housing 200 is provided with a plurality of second limiting parts 140. The first limiting parts 130 and the second limiting parts 140 are used to fix the wiring of the integrated board 400 and the cell 300, so that the wiring is neat and orderly, and avoids the inconvenience caused to the workers by messy wiring when the battery module 10 is being repaired.

[0027] In one embodiment, the first support plate 110 has a rectangular structure, and a plurality of first reinforcing parts 111 are evenly distributed on the first support plate 110, thereby increasing the strength of the first housing 100 to resist the expansion and deformation of the battery cell 300, thereby extending the service life of the battery module 10. The second support plate 210 has a rectangular structure, and a plurality of second reinforcing parts 121 are evenly distributed on the second support plate 210, thereby increasing the strength of the second housing 200 to resist the expansion and deformation of the battery cell 300, thereby further extending the service life of the battery module 10.

[0028] In one embodiment, the first support plate 110 includes a first side 112 and a second side. The first side 112 is disposed on the side of the first support plate 110 away from the battery cell 300, and the second side is disposed on the side of the first support plate 110 close to the battery cell 300. The area of ​​the first side 112 is larger than the area of ​​the second side. The integrated board 400 is disposed on the first side 112. By disposing of the integrated board 400 on the side of the first support plate 110 with the larger area, it is convenient for manual installation of the integrated board 400 and at the same time meets the installation requirements of electronic components.

[0029] Please refer to it again. Figure 1 In one embodiment, the first support plate 110 is provided with a plurality of studs 113, and the integrated plate 400 is provided with a plurality of first connection holes 410. Each stud 113 and each first connection hole 410 are connected by fasteners, so that the integrated plate 400 and the first support plate 110 are firmly connected, and at the same time, it is convenient for manual removal of the integrated plate 400 from the first housing 100 when the battery module 10 needs maintenance.

[0030] Please refer to it again. Figure 1 In one embodiment, an insulating plate 600 is also included. In order to enhance the structural strength of the first housing 100, the first housing 100 is made of metal. The insulating plate 600 is disposed between the first housing 100 and the integrated plate 400, thereby improving the safety and reliability of the first housing 100 and the integrated plate 400.

[0031] Please refer to it again. Figure 1In one embodiment, the busbar 500 includes a positive busbar 510, which includes a first fixing part 511 and a second fixing part 512. The first fixing part 511 and the second fixing part 512 are respectively disposed on both sides of the positive busbar 510. The first fixing part 511 is welded to the positive electrode of the battery cell 300, thereby fixing the battery cell 300 to the positive busbar 510. The integrated board 400 is provided with a third connecting part 420, which is connected to the second fixing part 512 by fasteners, thereby fixing the integrated board 400 to the positive busbar 510. With this configuration, the positive busbar 510 not only provides current transmission but also serves to fix the battery cell 300, reducing the use of other fixing components and improving the space utilization of the battery module 10.

[0032] Please refer to it again. Figure 1 In one embodiment, the busbar further includes a negative busbar 520, which includes a third fixing part 521 and a fourth fixing part 522. The third fixing part 521 and the fourth fixing part 522 are respectively disposed on both sides of the negative busbar 520. The third fixing part 521 is welded to the negative electrode of the battery cell 300, thereby fixing the battery cell 300 to the negative busbar 520. A fourth connecting part 430 is provided on the integrated plate 400. The fourth connecting part 430 and the fourth fixing part 522 are connected by fasteners, thereby fixing the integrated plate 400 to the negative busbar 520. With this configuration, the negative busbar 520 not only provides current transmission but also further fixes the battery cell 300, further reducing the use of other fasteners and thus further improving the space utilization of the battery module 10.

[0033] Please refer to it again. Figure 1 In one embodiment, a plurality of buffer foams 310 are evenly distributed on the surface of the battery cell 300 to prevent the battery cell 300 from being damaged by impact, thereby improving the service life of the battery module 10.
