ABSTRACT:
The present invention relates to a battery powered thermal garment that is provided with a battery recharging circuit that is designed to recharge a battery package associated with said thermal garment approximately 30-40 times as fast as conventional recharging devices. In addition, the recharging circuit of the present invention is provided with a separate and direct power source for energizing the heating elements within said garment independently of said battery package. With respect to the recharging circuit, a transformer is provided for stepping down a AC voltage source and the transformer includes a dual tap, one for providing the independent power source to the garment and the other providing a recharging current. The recharging current is rectified and then directed through a silicon control rectifier to the battery package for recharging. The recharging circuit is designed to cease charging in response to the battery package having a certain level of charge or where the temperature within the battery package exceeds a selected temperature.
