[0054] In addition, multiple FPC boards 32 are connected to the first bus group 21 and the second bus group 22, so that multiple battery cells can be connected to the multiple FPC boards 32 through the first bus group 21 and the second bus group 22 respectively. It is more convenient to collect information on multiple battery cells through multiple FPC boards 32, and the collection component 30 is simpler to process, which is convenient for collecting signals from the battery cells and helps to improve the collection efficiency.

[0055] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the FPC board 32 includes a plurality of branches, and the plurality of branches are arranged at intervals in the width direction of the bracket body 10. One end of the plurality of branches is connected to the plug-in 31, and the other end of the plurality of branches extends along the length direction of the bracket body 10. The plurality of branches are connected to the plurality of sub-busbars 23 of the first busbar group 21 or the plurality of sub-busbars 23 of the second busbar group 22. Thus, the information on the plurality of cells can be collected through the plurality of sub-busbars 23 respectively through the plurality of branches, making the collection more convenient, and the collection component 30 is simpler to process, which is convenient for collecting signals of the cells and is conducive to improving the collection efficiency. In addition, the FPC board 32 has a simple structure and is easy to process and manufacture.

[0056] In some embodiments of the present invention, Figure 1-Figure 4As shown, the multiple branches include a first branch 321 and a second branch 322, one end of the first branch 321 is connected to the plug-in 31, and the second branch 322 includes an extension portion 41, a bending portion 42 and a connecting portion 43, one end of the extension portion 41 is connected to the plug-in 31, and the extension portion 41 extends along the length direction of the bracket body 10, and the extension portion 41 and the first branch 321 are spaced apart in the width direction of the bracket body 10 to facilitate the placement of the first branch 321 and the second branch 322 on the bracket body 10.

[0057] In addition, if Figure 1-Figure 4 As shown, the bending portion 42 and the end of the extension portion 41 away from the plug 31 (for example Figure 3 The connecting portion 43 is located on the same side of the first branch 321, and the connecting portion 43 and the first branch 321 are spaced apart in the length direction of the bracket body 10, and one end of the connecting portion 43 facing the first branch 321 is connected to one end of the bending portion 42 away from the extending portion 41, the first branch 321 is connected to part of the sub-bus 23 of the first bus group 21 or the second bus group 22, and the connecting portion 43 is connected to the remaining sub-bus 23 of the first bus group 21 or the second bus group 22.

[0058] In this way, the connection requirements of the first branch 321 and the second branch 322 with the sub-bus 23 on the same side can be realized, and the required information collection needs can be met.

When thermal runaway occurs in the battery cell, the battery cell can be depressurized and exhausted through the explosion-proof valve, and the gas can be discharged through the exhaust hole 11 to release the internal pressure of the battery cell and ensure the safety of the battery cell.

[0060] In the related art, due to insufficient space in the battery module, the FPC board will be opposite to the explosion-proof valve, so that the FPC board blocks the exhaust of the explosion-proof valve, which is not conducive to the discharge of high-temperature and high-pressure gas, and the FPC board is easily damaged during the exhaust process of the explosion-proof valve.

[0061] Therefore, in the present invention, multiple FPC boards 32 are arranged around the exhaust hole 11, and multiple FPC boards 32 are arranged at intervals in the thickness direction of the bracket body 10, which can effectively reduce the space in the width direction of the battery module occupied by the FPC boards 32, reduce the shielding area of ​​the explosion-proof valve by the FPC boards 32, and effectively make the FPC boards 32 avoid the explosion-proof valve.
