Abstract
A battery module has aligned battery cells, two plate members provided on the opposite ends in the aligning direction of the battery cells, fasteners joined to the plate members to integrate the battery cells, at least one connection bus bar, which connects terminals of adjacent battery cells in the aligning direction, and an elastic member, which absorbs expansion of the battery cells in the aligning direction. Each connection bus bar includes two connection portions connected to the terminals and a bend portion located between the two connection portions. In response to expansion in the aligning direction of the battery cells, the bend portion is extendable in the aligning direction. A total allowed deformation amount, which is based on the allowed deformation amount of the bend portions in the aligning direction, is set to be greater than or equal to the thickness in the aligning direction of the elastic member.
