Abstract
A power storage device includes: a power storage module in which a plurality of power storage cells are stacked along a stacking direction; and a case that accommodates the power storage module, wherein each of the power storage cells in the power storage module has a main surface extending in a direction substantially orthogonal to the stacking direction, and the case includes a supporting portion that supports, along the stacking direction, the power storage module accommodated in the case, and the case is provided with a recess that is provided at a position different from the supporting portion and that opens toward the main surface.
Claims12
A power storage device comprising:
- a power storage module in which a plurality of power storage cells are stacked along a stacking direction;
- and
- a case that accommodates the power storage module, wherein
- each of the power storage cells in the power storage module has a main surface extending in a direction substantially orthogonal to the stacking direction, and
- the case includes a supporting portion that supports, along the stacking direction, the power storage module accommodated in the case, and the case is provided with a recess that is provided at a position different from the supporting portion and that opens toward the main surface.
A method of manufacturing a power storage device, the method comprising:
- forming a power storage module by stacking a plurality of power storage cells along a stacking direction;
- sandwiching, using a jig, the power storage module in the stacking direction;
- inserting the jig and the power storage module into a case with the power storage module being sandwiched by the jig;
- and
- supporting the power storage module by the case along the stacking direction, wherein
- the inserting of the jig and the power storage module into the case includes inserting the jig into a recess provided in the case, and
- the supporting of the power storage module by the case includes restraining the power storage module by a supporting portion provided at a position different from the recess in the case.
