Abstract
A battery module includes a first battery cell and a neighboring second battery cell. The battery module also includes a heat sink in contact with and configured to absorb thermal energy from each of the first battery cell and the second battery cell. The battery module additionally includes a module enclosure surrounded by ambient environment and configured to house each of the first battery cell, the second battery cell, and the heat sink. The battery module further includes a heat transfer mechanism having a first switch configured to detect temperature of the first battery cell exceeding a predetermined value indicative of a thermal runaway event. The heat transfer mechanism is also configured to transfer thermal energy from the first battery cell to the module enclosure to thereby control propagation of the thermal runaway event to the second battery cell.
