Abstract:
1. A battery module, comprising: a plurality of adjoining battery cells; heat conductive sheets, a heat conductive sheet among the heat conductive sheets between adjacent battery cells, the heat conductive sheets being in thermal co-operation with the battery cells; a heat dispersion member coupled with the heat conductive sheets and in thermal co-operation therewith; a heat dissipation member coupled with the heat dispersion member and in thermal co-operation therewith; and one or more heat conductive subsidiary sheets between adjacent battery cells in a center portion of the battery module; a housing accommodating the battery cells, wherein: the battery cells are arranged in a stack that extends in a first direction, the heat dispersion member is between the heat dissipation member and the battery cells, the heat dispersion member including a coolant path for a coolant to flow therethrough, the coolant path including a plurality of heat pipes, each of the heat conductive sheets includes a heat absorption part and a heat radiation part, the heat absorption part being between the adjacent battery cells and in thermal co-operation with a wide side surface of the battery cells, the heat radiation part being bent to extend away from the heat absorption part and being between the battery cells and the heat dispersion member, the heat conductive sheets are installed through a bottom of the housing, and the heat radiation part is in thermal cooperation with an exterior of the bottom.
