ABSTRACT:
A battery warmer for warming the battery set of an electrically powered vehicle is disclosed. A resistive heating battery warmer is provided that increases the temperature around the batteries during down time and during charging. The batteries maintain the warmth generated by the warmer in an insulated battery compartment even during operation at cooler temperatures. Also, during operation, warmth is restored to the battery compartment by ducting from the electric motors or by using a generator to drive a small engine to power heating coils to maintain the battery temperature.
