Abstract
Systems and methods that provide improved cooling for batteries are disclosed. A battery system according to the present disclosure may include a cooling plate, one or more battery cells coupled to one surface of the cooling plate, and one or more battery cells coupled to the opposite surface of the cooling plate. The cooling plate and corresponding batteries may be included in a battery module, and multiple battery modules electrically connected may make up a battery pack. The cooling plates may comprise channels for cooling fluid, which may be provided to the plates in parallel from a cooling fluid source. Cooling the battery cells at the ends of the cells, where they are coupled to the cooling plate, may advantageously provide one or more of improved energy density, thermal management, and safety.
