Abstract
Abstract An electric vehicle having a non-metallic body portion and equipped with an inductive charging coil for charging the vehicle's battery while the electric vehicle is moving includes a magnetic flux barrier attached to the non-metallic body portion and encompassing a passenger compartment of the electric vehicle for resisting penetration of magnetic flux into the passenger compartment. The inductive charging coil may be formed of wire wound around the body of the electric vehicle or, alternatively, may be formed of stripes etched on the body surface or of flexible adhesive conductors.
