Abstract
A heat transfer system includes first and second battery cells, a heat sink, and a plurality of sheets of a thermally conductive material arranged in a stack. The first and second battery cells are arranged adjacent to each other. The heat sink is arranged adjacent to the first and second battery cells. A first portion of the stack is disposed between the first and second battery cells. A second portion of the stack is disposed adjacent to and in thermal communication with the heat sink. The first portion of the stack conducts heat from the first battery cell while limiting heat conducted to the second battery cell. The second portion of the stack transfers the heat to the heat sink.
