Abstract
A method includes: receiving vehicle information from a wireless charging-capable vehicle via a wireless communication means; calculating an air gap between a primary coil of a wireless charging system that is operable to wirelessly charge the vehicle and a secondary coil of the vehicle based on the received vehicle information; and causing electric current to flow only through a portion of the primary coil having a size that is less than or equal to a size of the entire primary coil. The size of the portion of the primary coil through which the electric current flows is determined based on the calculated air gap between the primary coil and the secondary coil.
Claims23
A method comprising:
- receiving vehicle information from a wireless charging-capable vehicle via a wireless communication means;
- calculating an air gap between a primary coil of a wireless charging system that is operable to wirelessly charge the vehicle and a secondary coil of the vehicle based on the received vehicle information;
- and
- causing electric current to flow only through a portion of the primary coil having a size that is less than or equal to a size of the entire primary coil,
- wherein the size of the portion of the primary coil through which the electric current flows is determined based on the calculated air gap between the primary coil and the secondary coil.
A wireless charging system comprising:
- wireless communication means wirelessly receiving vehicle information from a wireless charging-capable vehicle;
- a controller calculating an air gap between a primary coil of the wireless charging system that is operable to wirelessly charge the vehicle and a secondary coil of the vehicle based on the received vehicle information;
- and
- an LC circuit causing electric current to flow only through a portion of the primary coil having a size that is less than or equal to a size of the entire primary coil,
- wherein size of the portion of the primary coil through which the electric current flows is determined based on the calculated air gap between the primary coil and the secondary coil.
