Abstract:
1. A battery module having a plurality of interconnected electrochemical cells disposed within a cooling plate assembly comprising two non-contiguous cooling plates, each cooling plate comprising a side panel contiguous with a base panel, the cooling plates disposed opposite one another such that the base panels are coplanar and separated by a gap, each side panel comprising an inlet duct running across the battery module from front to back along an upper edge of the side panel, and a manifold comprising coolant channels in fluid communication with the inlet duct, and each base panel comprising an outlet duct in fluid communication with a manifold; each cell having a top portion, a bottom portion, and two side portions, the cells being in parallel alignment in the cooling plate assembly such that the side portions are in heat-transfer contact with the manifolds, the bottom portions are in heat-transfer contact with the outlet ducts, and the upper edges of the side panels extend above the top portions of the cells; each inlet duct comprising at least one inlet port at the front, and each outlet duct comprising at least one outlet port at the front; wherein the coolant channels and ducts are configured to reduce operational temperature variation in the cells across the battery module from front to back, and within each battery cell from top to bottom.
