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.

Claims

1. An electric vehicle comprising a non-metallic body portion, magnetic flux barrier means, attached to said non-metallic body portion and encompassing a passenger compartment of the electric vehicle, for resisting penetration of magnetic flux, and inductive coil means, mounted on said electric vehicle outside of said magnetic flux barrier, for producing an induced electromotive force.

2. The apparatus of claim 1 wherein said magnetic flux barrier comprises a layer of anti-magnetic paint.

3. The apparatus of claim 1 wherein said magnetic flux barrier comprises a metal conduction layer.

4. The apparatus of claim 1 wherein said inductive coil means comprises wire wound around a body of said electric vehicle.

5. The apparatus of claim 1 wherein said inductive coil means comprises stripes etched on a body surface of said electric car.

6. The apparatus of claim 1 wherein said inductive coil means comprises flexible adhesive conductor means.
