Abstract
A battery module including an array of cooling fins having different thicknesses is provided. The battery module includes: a plurality of battery units arranged in one direction; a plurality of cooling fins between adjacent battery units; and a heat sink coupled to ends of the plurality of cooling fins, wherein each cooling fin has a structure in which a pair of sub-cooling fins are face-to-face coupled to each other, and thicknesses of the plurality of cooling fins are reduced toward the side region from the central region due to a difference in a thickness of at least one of the pair of sub-cooling fins. Since heat is not accumulated at the central region, the battery module has uniform temperature distribution while being charged or discharged.
