  • Patent number: 8343650
    Abstract: A modular assembly for housing battery cells. The modular assembly includes a plurality of U-shaped members having cooling fluid channels, where the U-shaped members are mounted together in a stacked manner. Each cooling fluid channel includes an inlet and outlet orifice, where the orifices in the stacked U-shaped members align with each other. The modular assembly also includes a plurality of thermally conductive carrier plates, where a battery cell is mounted to and between opposing carrier plates. Side edges of the carrier plates are mounted in opposing retention slots in opposing U-shaped members where a cooling fluid channel in the U-shaped member is provided within the retention slot so that a cooling fluid flowing through the cooling fluid channel and the U-shaped members contacts the carrier plates and draws heat therefrom.
