Abstract: Provided are a battery module information collection and connection system and a powered device. The system includes an insulating bracket, flexible circuit boards, a battery control member, a first conductive portion, a collection member and a battery module. The insulating bracket is disposed on the battery module. The flexible circuit boards include a first flexible circuit board and a second flexible circuit board. The flexible circuit board is connected to the battery control member, and the cell is connected to a flexible circuit board. The battery control member is connected to the battery module. The first conductive portion is disposed on a side of the insulating bracket. One end of the first conductive portion is connected to the battery control member, and the other end of the first conductive portion is connected to a high-voltage interface, and the high-voltage interface is communicatively connected to the battery control member.
