Abstract: A battery pack includes a battery assembly including battery cells and spacers that are alternately arrayed, a side plate extending across a side of the battery assembly, and a motion prevention unit protruding from the side plate toward the battery assembly so as to cover a portion of the battery assembly, the motion prevention unit being arrayed on the spacers.

Abstract: A battery pack including a plurality of battery cells; a case frame having an opened end, the case frame receiving the plurality of battery cells; and a finishing plate coupled with the opened end of the case frame, wherein the case frame includes a pair of side plates extending in an arrangement direction of the battery cells to cover lateral sides of the battery cells; and an end plate between the side plates, the end plate closing an end of the case frame, and wherein the side plates and the end plate are a one piece structure.

Abstract: A battery pack assembly including: an inner pack accommodating a plurality of secondary cells; an outer pack accommodating the inner pack; a first shock absorbing member between a first surface of the inner pack and a first surface of the outer pack, the first shock absorbing member configured to absorb a shock between the inner pack and the outer pack; and a second shock absorbing member between at least a side surface of the inner pack and a side surface of the outer pack among surfaces of the inner pack and the outer pack other than the first surfaces, the second shock absorbing member configured to absorb a shock between the inner pack and the outer pack.
