BATTERY MODULE

The present disclosure relates to a battery module, including two or more battery cells (1), each including an electrode terminal (11); a connecting member (2), wherein the electrode terminals (11) of adjacent battery cells (1) are connected by the connecting member (2); and a clamping-sampling member (3), including a wire connection portion (37) for fixing a wire harness (4) and a clamping portion, wherein one end of the clamping portion is connected with the wire connection portion (37) and the other end of the clamping portion clamps the connecting member (2). The wire harness for information collection in the battery module is connected to the connecting member by clamping the connecting member to the clamping-sampling member, instead of directly welding the wire harness with the connecting member. The information collection is achieved by directly fixing the wire harness on the wire connection portion and then clamping the connecting member to the clamping portion, which can effectively improve connection strength between the wire harness for information collection and the connecting member.
