Abstract
The present invention provides a battery case comprising: a side frame; longitudinal members which are arranged in the side frame and extend in the longitudinal direction; width-direction members which are arranged in the side frame and extend in the width-direction so as to be connected crosswise with the longitudinal members, and which each include a first lower width-direction unit and a second lower width-direction unit that are arranged overlapping in the height direction; and a cooling panel which is arranged above the first lower width-direction units and cools a battery module.
Claims19
A battery case, comprising:
- a side frame;
- a longitudinal member disposed in the side frame and extending in a length direction;
- a width-direction member disposed in the side frame, extending in a width direction, connected to intersect with the longitudinal member, and including a first lower width-direction unit and a second lower width-direction unit disposed to overlap each other in a height direction;
- and
- a cooling panel disposed on an upper side of the first lower width-direction unit and cooling the battery module.
A battery case, comprising:
- a side frame;
- a longitudinal member extending in the side frame in a length direction;
- and
- a width-direction member extending in the side frame in a width direction and connected to intersect with the longitudinal member,
- wherein the longitudinal member includes:
- a lower longitudinal unit disposed on a lower side;
- and
- an upper longitudinal unit including a plurality of first variable units having different heights, wherein at least one of the plurality of first variable units is coupled to an upper side of the lower longitudinal unit.
