摘要： A battery module includes a first guard and a plurality of battery cells. The plurality of battery cells are arranged along a first direction. One end of the battery cell in a second direction is provided with a pressure relief mechanism. The second direction is perpendicular to the first direction. The pressure relief mechanism is configured to release the internal pressure of the battery cell when the internal pressure or temperature of the battery cell reaches a threshold value. The first guard includes a first guarding portion covering the end of the plurality of battery cells provided with the pressure relief mechanism. A plurality of venting ports are provided on the first guarding portion, and the venting port and the pressure relief mechanism are provided in a staggered manner in the second direction.
