To suppress a decrease in energy density while increasing the rigidity of a battery module.SOLUTION: A battery module 1 includes a cell stack 2 in which a plurality of battery cells 2a are stacked in a predetermined stacking direction Do, a pair of end plates 3 arranged on both end faces of the cell stack 2 in the stacking direction Do, and an intermediate plate 4 arranged in the intermediate portion of the cell stack 2 in the stacking direction. The intermediate plate 4 includes a pair of main surfaces 4a facing the battery cell 2a, a plurality of side surfaces 4b connecting outer edges of the main surface 4a, and a recessed portion 4d extending in an intersecting direction Dw that intersects with the stacking direction Do on at least one of the plurality of side surfaces 4b.SELECTED DRAWING: Figure 2
【課題】バッテリモジュールの剛性を高めつつ、エネルギー密度の低下を抑制する。【解決手段】バッテリモジュール1は、複数のバッテリセル2aが所定の積層方向Doに積層されたセル積層体2と、セル積層体2の積層方向Doの両端面に配置された一対のエンドプレート3と、セル積層体2の積層方向Doの中間部に配置された中間プレート4とを含む。中間プレート4は、バッテリセル2aに対向する一対の主面4aと、主面4aの外縁どうしを繋ぐ複数の側面4bと、複数の側面4bの少なくとも一つにおいて積層方向Doと交差する交差方向Dwに延びる凹部4dとを有する。【選択図】図2
