Zusammenfassung:	A battery module (30) for use in an electric vehicle includes a housing (41) and a member (32) provided within the housing (41) that contains a plurality of electrochemical cells (40). The member (32) includes apertures (36) in an outer surface of the member (32) that allow a thermal management fluid to exit the member (32) after passing adjacent outer surfaces of the plurality of the electrochemical cells (40) within the member (32). The apertures (36) include apertures of a first size (36c) near a first end of the member (32) and apertures of a second size (36a) larger than the first size near a second opposite end of the member (32) to provide relatively even thermal regulation among the plurality of electrochemical cells (40).
