Abstract:
This invention relates to a wireless vehicle recharging apparatus for an energy storage element of a vehicle. The apparatus has at least one drive unit arrangement coupled to at least one drive coil arrangement disposed for generating a magnetic field extending from the drive coil arrangement, and includes a corresponding vehicle-mounted pickup coil arrangement coupled to a power conditioning circuit arrangement for receiving the extending magnetic field. The drive unit arrangement is operable to excite the drive coil arrangement at a fundamental frequency and the drive coil arrangement is implemented to be substantially devoid of ferromagnetic components for providing a path for the extending magnetic field. Additional aspects of the invention relate to vehicle power coupling apparatus including pickup coil arrangements.
