ELECTRIC VEHICLE THERMAL MANAGEMENT SYSTEM WITH THERMAL CONTROL POUCHES

One aspect provides a battery cooling pouch including a first thin film sheet defined as a first cooling fin having a first major surface to contact a battery cell, a second thin film sheet defined as a second cooling fin having a first major surface, and a panel insert of a polymeric material, wherein perimeter edges of the first and second thin film sheets are sealed to confine the panel insert between the first and second thin film sheets, the panel insert having a major surface defining coolant flow grooves exposed to the first thin film sheet to form coolant flow channels. The cooling pouch includes at least one interior seal between at least a portion of the first thin film sheet and the major surface of the panel insert to direct a coolant fluid through the coolant flow channels.
