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.

A battery pack assembly, comprising:
- a cell stack including 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 disposed between axially adjacent battery cells within the plurality of battery cells, each thermal energy transfer assembly including a first sheet and a second sheet that sandwich an insulation layer;
- a coolant plate assembly;
- and
- a base sheet sandwiched between the coolant plate assembly and the cell stack, the base sheet configured to communicate thermal energy from the first sheet and the second sheet to the coolant plate assembly.
A method of thermal transfer within a battery pack, comprising:
- communicating thermal energy from a battery cell in a cell stack to a first sheet of a thermal energy transfer assembly;
- insulating the first sheet from a second sheet of the thermal energy transfer assembly using an insulation layer of the thermal energy transfer assembly;
- communicating thermal energy from the first sheet to a base sheet that is sandwiched between a coolant plate assembly and the cell stack;
- and
- communicating thermal energy from the base sheet to the coolant plate assembly.
