Patent ID: 8628872

Claim:
A battery cell assembly, comprising: a first battery cell having a first side and a second side opposite the first side; a first panel member configured to contact at least a portion of the first side of the first battery cell; and a heat exchanger having a rectangular ring-shaped plastic frame and first and second thermally conductive layers, the rectangular ring-shaped plastic frame having an interior space extending therethrough, the rectangular ring-shaped plastic frame having a third side and a fourth side opposite the third side, the first thermally conductive layer being disposed on the third side of the rectangular ring-shaped plastic frame and covering the interior space, the second thermally conductive layer being disposed on the fourth side of the rectangular ring-shaped plastic frame and covering the interior space, the first thermally conductive layer being disposed adjacent the second side of the first battery cell, such that when a liquid is disposed in the interior space, heat energy is transferred from the first battery cell through the first thermally conductive layer to the liquid.
