Abstract

Systems, methods and a cooling module are described. The cooling module is configured to directly cool the plurality of battery cell tabs. The cooling module includes a generally prismatic isolation sheet contacting the battery cell tabs along a common plane and a heat exchanger. The heat exchanger includes a metallic portion defining an open cavity and a lightweight portion joined to the metallic portion to define a unitary flow assembly. The metallic portion includes an outer planar surface engaging the second planar surface. The lightweight portion is formed from a thermally conductive plastic material and includes baffles integrally formed with and extending therefrom. The plurality of baffles engage an interior surface of the metallic portion to thereby define a serpentine path for the cooling fluid.
