Abstract
Battery cells are disposed apart from each other in a housing of a battery module included in a power storage device. In the battery module, a partition member is provided that divides a space in the housing into a high temperature region, which contains battery cells located centrally in a disposal direction of the battery cells, and a low temperature region, which contains battery cells located at end portions in the disposal direction of the battery cells. The cooling air flow supplied from a fan passes between the battery cells in the high temperature region, passes through ventilation holes provided in the partition members, enters the low temperature region, passes between the battery cells in the low temperature region, passes through a discharge hole, and flows outside of the housing.
