Abstract
A power storage device includes a housing case, a stack, a thermally conductive material, and support members. Each of the support members includes a first support portion extending in an up-down direction, a second support portion extending in a stacking direction, and a bending portion where the first support portion intersects the second support portion. Each of the support members is fixed to the stack at the first support portion and to the housing case at the second support portion. The bending portion is in contact with the stack on a side farther away from the thermally conductive material than a center of the stack in a height direction. The first support portion extends from the bending portion toward the thermally conductive material.
Claims5
A power storage device comprising:
- a housing case;
- a stack including a plurality of stacked battery cells housed in the housing case;
- a thermally conductive material configured to transfer heat of the battery cells upward or downward from the stack;
- and
- support members that fix the housing case and the stack at positions where the support members sandwich the stack in a stacking direction, wherein
- each of the support members includes a first support portion extending in an up-down direction, a second support portion extending in the stacking direction, and a bending portion where the first support portion intersects the second support portion,
- each of the support members is fixed to the stack at the first support portion and to the housing case at the second support portion,
- the bending portion is in contact with the stack on a side farther away from the thermally conductive material than a center of the stack in a height direction, and
- the first support portion extends from the bending portion toward the thermally conductive material.
