Patent ID: 8114539

Claim:
A battery module configured in a structure in which battery cartridges are sequentially stacked in a state in which battery cells are mounted in the battery cartridges, and a heat dissipation member is disposed in at least one interface between the battery cartridges, wherein each of the battery cartridges are configured in a frame structure to mount a plate-shaped battery cell therein, each of the battery cartridges comprising a pair of plate-shaped frames configured to fix an outer circumference of the battery cell in a state in which at least one side of the battery cell is open, wherein each of the frames is provided at an outside thereof with an elastic pressing member configured to fix a heat dissipation member to the open side of the battery cell in a tight contact manner upon manufacture of the battery module, wherein the elastic pressing member is mounted to at least one selected from a group consisting of an upper side region, a lower side region, a left side region, and a right side region of the outside of each of the frames, wherein the heat dissipation member comprises a first heat dissipation member and a second heat dissipation member, the first heat dissipation member extends such that one side of the first heat dissipation member covers at least a portion of outermost battery cartridge (a) of the battery module, wherein outermost battery cartridge (a) is one of the outermost battery cartridges of the battery module, and the other side of the first heat dissipation member is disposed between the inner battery cartridges, and the second heat dissipation member extends such that one side of the second heat dissipation member covers at least a portion of the outermost battery cartridge (a) of the battery module in a state in which the second heat dissipation member does not overlap with the first heat dissipation member, and the other side of the second heat dissipation member is disposed between the inner battery cartridges, and the second heat dissipation member does not occupy the space between the same inner battery cartridges as the first heat dissipation member.
