Abstract
A support structure for a battery pack and a battery pack including the support structure and battery cells, the support structure including a base plate; a thermal plate positioned between the battery cell and the base plate; a thermally conductive material between the battery cell and the thermal plate; and a compressible support between the thermal plate and the base plate.
Claims23
A battery pack including:
- battery cells and a support structure, the support structure comprising:
- a base plate;
- a thermal plate positioned between the battery cells and the base plate, the thermal plate receiving a flow of fluid that adjusts a temperature of the battery cells;
- a thermally conductive material, comprising a thermal gap pad, between the battery cell and the thermal plate;
- and
- a compressible support, comprising compressible foam, between the thermal plate and the base plate and configured to support the thermal plate and the thermal gap pad against the battery cells with a constant force.

A method of making a battery pack, comprising:
- providing a base plate;
- providing a cooling plate;
- positioning a compressible support, comprising compressible foam, between the cooling plate and the base plate;
- positioning a thermal gap pad on the cooling plate;
- and
- positioning a battery cell in contact with the thermal gap pad, the battery pack supported by the base plate and pressed against the thermal gap pad with a predetermined force provided by the compressible support and the thermal gap pad, the cooling plate receiving a flow of fluid that adjusts a temperature of the battery cell.
