[0034] Specifically, one side of the PCB (Printed Circuit Board) is provided with a wire to realize the electrical connection between the BMS control board and the positive connection module 110, the negative connection module 120, the sampling module 130, the current control module 140 and the current limiting module 150. The BMS control board 200 is the core part of the battery management assembly, and the BMS control board 200 can monitor the voltage, current and temperature and other information of the battery through the devices such as the sampling module 130, the current control module 140 and the current limiting module 150 connected thereto. The current flowing through the sampling module 130, the current control module 140 and the current limiting module 150 directly connected with the positive or negative electrode of the battery is large, and the temperature and the heat emitted are high, while the current flowing through the BMS control board 200 body is small, which will not cause high temperature and heat.

One end of the current limiting module 150 is connected to the positive connection module 110 through the wiring on the PCB board 100, and the other end is connected to the second end of the BMS control board 200 through the wiring. The current limiting module 150 can be a fuse, which can cut off the current when the current in the battery abnormally rises to a certain height and heat, to protect the components on the PCB board 100 from being burned out. The current limiting module 150 can be arranged at the part of the PCB board 100 close to the BMS control board 200, to reduce the influence of heat dissipation between the positive connection module 110 and the current limiting module 150.
