Abstract

A charging device for providing power to 12-Volt circuits of an electric vehicle. The charging device comprises a cylindrical fan having a plurality of blades extending radially from an outer surface thereof, a winding connected to an inner surface of the fan and wrapped around an armature. The fan spins when the vehicle is in motion enabling the winding and armature to generate electricity. The electricity is provided to a vehicle's 12-Volt battery or directly to 12-Volt circuits of the vehicle. The charging device can be positioned at any appropriate position on the vehicle and can be integrated or retrofitted.
