The present disclosure relates to a casing for a battery pack and a battery pack. The casing has a receiving space and an opening in communication with the receiving space, the receiving space is formed by a wall portion of the casing, and the wall portion is formed from two or more stacked base plates, between which a plurality of cavities are formed. By forming a plurality of cavities in the wall portion, the casing for a battery pack provided by the present disclosure not only can improve the bearing capacity and the impact resistance of the casing, but also can achieve a thermal management of the battery assembly by filling the plurality of cavities with a phase change material or cooling liquid, which can further improve the mechanical property of the casing with a relatively light weight and relatively high reliability.

Power supply device includes battery stack in which a plurality of prismatic battery cells are stacked, end plate having a rectangular shape in plan view and having a pressing surface that covers an end surface of battery stack, and fastening member that fastens battery stack. End plate has, on a pressing surface, flat pressing regions respectively formed on end edge sides in the up-down direction, and bead region formed on the middle side in the up-down direction and bent in a shape protruding toward the back surface side of the pressing surface. Thus, strength can be improved by changing a shape in which bead region is formed in the middle while pressing regions that presses battery stack remains on end plate, which enables end plate having high strength to be provided at low cost.
