ABSTRACT:
An inductive charging coupler for use in an inductive charging apparatus used to charge a battery. The charging coupler is insertable into a charge port that is coupled to the battery. The charge port comprises a housing, an opening into which the charging coupler is inserted, and a ferrite core surrounded by secondary windings. The charging coupler comprises a housing having a hollow disk-shaped section with substantially flat opposed surfaces and a tapered handle extending therefrom. An opening is disposed through each of the flat opposed surfaces. A center magnetic core is disposed in the opening and has opposed flat surfaces that are substantially coplanar with the substantially flat opposed surfaces of the housing. A primary winding is disposed in the hollow disk-shaped section around the center magnetic core. The coupler has the shape of a paddle and is designed to give a vehicle operator a sense of safety when transferring electric power to the battery of an electric vehicle, for example.
