Abstract
A battery assembly is provided that utilizes electrically isolated heat sinks to enhance battery pack thermal management and safety. The battery assembly is divided into groups of batteries, where the batteries within each group are of the same voltage, and where each battery group is serially coupled to the other battery groups. The heat sink is segmented, where each heat sink segment is thermally coupled to the batteries within a single battery group, and where each heat sink segment is electrically isolated from the adjacent heat sink segments. The heat sink segments are thermally coupled to a cold plate, and electrically isolated from the cold plate by a layer of a thermal interface material.
