ABSTRACT:
An inductive coupler for use in a battery charging system for an electric vehicle has a primary device having a primary coil and a core and a secondary device having a secondary coil and core. The primary and secondary devices are coupleable together with the primary coil placed within an open space defined by the secondary coil. The secondary coil is formed and sized so as to have a greater dimension than the primary coil as measured in the longitudinal direction of an electric vehicle parked for battery charging so that a space interval between the two coils in the longitudinal direction of the vehicle is greater than that in the lateral direction of the vehicle.
