Abstract: A battery module is provided, including: a battery group, including a plurality of batteries that is stacked; two end plates, respectively disposed at two ends of the battery group along a direction in which the plurality of batteries is stacked; and a connecting member, connecting the two end plates. Each of the two end plates has a middle section and thinned sections respectively located at two sides of the middle section in a length direction Y. A thickness of each of the thinned sections is smaller than a thickness of the middle section. Each of the thinned sections is provided with at least one strengthened portion protruding from an outer side surface of the thinned section. In the present disclosure, an overall weight of the battery module can be reduced when the thinned section has a smaller thickness than the middle section.
