摘要： The present disclosure provides a battery module, which comprises: a harness isolation board provided with a mounting groove; an output pole connection sheet; and a fixing assembly. The fixing assembly comprises: a connecting member placed in the mounting groove to be fixed on the harness isolation board; and a fastening member securely connected to the connecting member and fixing the output pole connection sheet. The connecting member and the fastening member are separately formed and securely connected together, the fastening member is fixed on the harness isolation board via the connecting member, thus the fixing manner between the connecting member and the harness isolation board is not related to the fastening member, and in turn it only needs to improve the structure of the connecting member and the harness isolation board to enhance the connecting strength and the anti-torque effect between the fixing assembly and the harness isolation board.
