Battery pack

Abstract

A battery pack has a plurality of cell laminates in which battery cells are stacked, a battery case accommodating the cell laminates, and a water jacket provided below the cell laminates and configured to allow a refrigerant for adjusting a temperature of the cell laminates to flow therethrough. The plurality of cell laminates include a first cell laminates group provided on one side in a predetermined direction and a second cell laminates group provided on the other side in the predetermined direction. The water jacket has a branch that branches into at least a first flow path and a second flow path from an inlet. The refrigerant flows through the first flow path in order of the first cell laminates group and the second cell laminates group. The refrigerant flows through the second flow path in order of the second cell laminates group and the first cell laminates group.
