Abstract
A battery pack is disclosed. The battery pack includes angular-shaped battery cells stacked in a stack direction and a battery holder device. The battery holder device presses side surfaces of the battery cells with a load acting along the stack direction. The battery holder device integrally includes multiple surface pressing members each interposed between adjacent battery cells and multiple connection members each connecting adjacent surface pressing members. Rigidity of each connection member against the load acting along the stack direction is smaller than rigidity of each surface pressing member against the load acing along the stack direction.
Claims9
A battery pack comprising:
- a plurality of angular-shaped battery cells that is stacked in a stack direction;
- and
- a battery holder device that presses side surfaces, which are normal to the stack direction, of the plurality of battery cells with a load acting along the stack direction to integrate the battery pack,
- wherein:
- the battery holder device integrally includes
- a plurality of surface pressing members each interposed between adjacent battery cells so that the plurality of surface pressing members presses the side surfaces, which are normal to the stack direction, of the plurality of battery cells, and
- a plurality of connection members each connecting adjacent surface pressing members, which are adjacent to each other in the stack direction;
- and
- rigidity of each connection member against the load acting along the stack direction is smaller than rigidity of each surface pressing member against the load acing along the stack direction.
