Claim 0:
1. A wireless power transfer arrangement used by an electric vehicle for a wireless power transfer across an airgap by inductive coupling for charging an energy storage used by the electric vehicle, wherein
a) the wireless power transfer arrangement includes a primary unit, a secondary unit and a controller for controlling the power transfer, wherein
b) the primary unit includes a wireless transceiver and a primary pad for inducing a magnetic field into the airgap, wherein
c) the secondary unit includes a wireless transceiver and a secondary pad for receiving the power transferred through the magnetic field, wherein
d) the wireless transceivers include an antenna for transmitting and receiving a communication signal via a wireless communication link between the primary unit and the secondary unit, wherein
e) the wireless communication link has a communication range that is less than twice a largest spatial extent of the primary pad, wherein the controller is adapted to control the power transfer based on data transmitted through the wireless communication link during the power transfer, wherein the controller is adapted to establish a closed control loop for a closed-loop control of the power transfer, wherein the controller is adapted to control the inducing of the magnetic field by the primary unit based on parameters of the energy storage, and wherein the closed control loop includes the wireless communications link.
