Abstract:
A method and apparatus for a self-heating battery pack uses a battery cells of a first battery cell circuit to power a device. However these battery cells become substantially inoperative below a very cold temperature, so a second battery cell circuit, having a second type of battery cells which can operate at the cold temperature, is used to power a heating element to warm up the first battery cells to a temperature at which they can operate.
