1. 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.
