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.

Abstract: A method and device for wireless power transfer. The device includes a first sensor, a second sensor, and an electronic controller. The method includes determining, by the electronic controller, whether the first sensor senses a magnetic field. The method further includes determining, by the electronic controller, whether the second sensor senses the magnetic field. The method further includes determining, by the electronic controller, that the portable electronic device is in use when only the first sensor senses the magnetic field. The method further includes determining, by the electronic controller, that the portable electronic device is in storage when both the first and second sensors sense the magnetic field.
