  • Patent number: 5821728
    Abstract: Batteries of a moving electric vehicle are charged using an electromagnetic field extended along the centerline of a driving lane and a level controlled armature mounted on the underside of an electric vehicle by having the moving coils of the armature lowered to optimum proximity of the magnetic field as the moving vehicle straddles and traveress over the magnetic field. Current will be induced into the armature coils by the relative motion between the armature coils and the primary inductive coils. For billing purposes a vehicle is identified and timed as it enters and leaves the charging lane by means of a vehicle mounted bar code and scanners located at the entrance and exit of the charging lane. The billing information is relayed to a data storage and process center.
