Claim 18:
19. A method for a wireless power transfer across an airgap by inductive coupling for charging an energy storage of an electric vehicle, the method including the steps of
a) inducing a magnetic field into the airgap with a primary pad of a primary unit,
b) receiving the power transferred through the magnetic field with a secondary pad of a secondary unit comprised by the vehicle,
c) providing a wireless communication link between the primary unit and the secondary unit,
d) providing the wireless communication link with a communication range that is less than twice a largest spatial extent of the primary pad and controlling the wireless power transfer by transmitting data through the wireless communication link during the power transfer, and
e) establishing a closed control loop for a closed-loop control of the power transfer, the closed-loop control comprising controlling the inducing of the magnetic field by the primary unit based on parameters of the energy storage, wherein the closed control loop includes the wireless communication link.
