To provide a battery module in which cell reaction force on an end plate caused by expansion of a battery is reduced using a simple structure and the weight of the end plate is reduced.SOLUTION: A battery module includes: a battery stack 2 obtained by stacking a plurality of rectangular battery cells 1 in the thickness direction; a pair of end plates 3 provided to the two end surfaces of the battery stack 2 in the stacking direction; and binder bars which are connected to the pair of end plates 3. The end plates 3 have, on surfaces thereof which face the battery stack 2, recesses 11 which allow expansion of the battery stack 2, and which become deeper towards central portions.SELECTED DRAWING: Figure 2
【課題】簡単な構造で電池の膨張に起因するエンドプレートのセル反力を減少してエンドプレートを軽量化する。【解決手段】電池モジュールは、複数の角形電池セル1を厚さ方向に積層してなる電池積層体2と、電池積層体2の積層方向の両端面に配置してなる一対のエンドプレート3と、一対のエンドプレート3に連結されるバインドバーとを備え、エンドプレート3は、電池積層体2との対向面に、中央部に向かって深くなる電池積層体2の膨張許容凹部11を設けている。【選択図】図2
