Abstract
A battery pack for an electric vehicle or a hybrid vehicle may include a housing, a stack of battery cells disposed within the housing, and a cooling subassembly. The housing typically holds the cell stack together, and the cooling subassembly typically cools the cell stack to prevent damage to the battery cells and to maintain the performance of the battery cells. The cooling subassembly may include a cold plate defining a liquid flow channel and one or more thermoelectric devices (TEDs) that are operable to cool the cell stack when current is supplied thereto. Heat spreaders may be employed within the battery pack, and exemplary configurations of components to thermally and mechanically couple the cooling subassembly are described.
