BATTERY MODULE

Abstract:

Provided is a battery module in which torsion residual stress in a rod-shaped connecting member that fastens end plates is minimized so that looseness of the end plate fastening member can be prevented during use. A battery module in which a stacked body of a plurality of battery cells is pinched and held by two end plates from both end sides in a stacking direction, includes a rod-shaped connecting member. The rod-shaped connecting member applies tension in directions opposite to each other to the two end plates on both the end sides. The rod-shaped connecting member includes fastening portions adjacent to one end plate, and includes a detent mechanism part in the vicinity of the fastening portions.
