Battery pack with multi-layered thermal energy transfer assembly and thermal energy transfer method

Abstract

A battery pack assembly includes a cell stack having a plurality of battery cells distributed along an axis and a plurality of thermal energy transfer assemblies distributed along the axis. Each thermal energy transfer assembly is disposed between axially adjacent battery cells within the plurality of battery cells. Each thermal energy transfer assembly includes a first sheet and a second sheet that sandwich an insulation layer. The battery pack assembly further includes a coolant plate assembly and a base sheet sandwiched between the coolant plate assembly and the cell stack. The base sheet is configured to communicate thermal energy from the first sheet and the second sheet to the coolant plate assembly.
