Abstract: Embodiments of this application provide a battery module, to improve consistency of cooling effects of battery cells, so that a battery cell group has a better states of health (SOH). The battery module includes: a heat dissipation mechanical part, which includes a first heat dissipation region and a second heat dissipation region. When an average distance between a heat dissipation pipe in the first heat dissipation region and a cooling medium outflow region is longer than an average distance between a heat dissipation pipe in the second heat dissipation region and the cooling medium outflow region, density of heat dissipation pipes in the first heat dissipation region is greater than density of heat dissipation pipes in the second heat dissipation region.
