  • Patent number: 11936017
    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.

  • Publication number: 20200031242
    Abstract: A thermoelectric module assembly for thermally conditioning a component includes first and second heat spreaders that are spaced apart from one another and configured to respectively provide cold and hot sides. An insulator plate is arranged between the first and second heat spreaders. The insulator plate has a compression limiter. A thermoelectric device is arranged with—in the insulator plate and operatively engaged with the first and second heat spreaders. A fastening element secures the first and second heat spreaders to one another about the insulator plate in an assembled condition. The compression limiters are configured to maintain a predetermined spacing between the first and second heat spreaders in the assembled condition.
