ABSTRACT:
A rechargeable battery pack that includes a controller, a temperature monitoring circuit, a rechargeable battery, and a heating circuit, can sense when the battery pack is exposed to a harmful low temperature and cause the heating circuit to heat the battery pack, particularly the battery pack's controller, so that it remains in a temperature regime compatible with normal operation. The rechargeable battery has a positive terminal and a negative terminal. The heater circuit is coupled to the rechargeable battery and the controller is coupled to the heater circuit. The temperature monitoring circuit is coupled to the controller. The temperature monitoring circuit is capable of measuring a temperature of the battery pack and providing a temperature indication. Based upon the indication, the controller causes the heater circuit to heat the controller.
