CIRCUIT BOARD, USE METHOD FOR CIRCUIT BOARD, BATTERY MODULE, AND VEHICLE

WIPO Patent Application WO/2020/134981

A1

A circuit board, a use method for the circuit board, a battery module, and a vehicle. A circuit board (1) comprises a conductive layer, a first bonding pad (12), and a second bonding pad (13). A sampling circuit (11) is formed on the conductive layer; the sampling circuit (11) is provided with a sampling end portion (111); an output end portion (112); a first branch (113) in which a first fuse region (S11) is formed; and a second branch (114) in which a second fuse region (S12) is formed. The first bonding pad (12) is provided at the sampling end portion (111), and the second bonding pad (13) is provided at the second branch (114). In the process of sampling, the first bonding pad (12) transfers the collected signal to an external controller by means of the sampling end portion (111) of the sampling circuit (11), the first branch (113), and the output end portion (112); after fusing occurs in the first fuse region (S11) of the first branch (113), because the second branch (114) is further provided in the sampling circuit (11), the second branch (114) and the second bonding pad (13) can be used for rapid repair to conduct the electrical connection between the sampling end portion (111) and the output end portion (112) when the circuit board (1) is returned to the factory for repair, thereby achieving the purpose of reusing the circuit board (1), so that the whole battery module is not scrapped and the utilization rate of the battery module is improved.
