Abstract
A wireless power transfer arrangement () for a wireless power transfer across an airgap () by inductive coupling, for example for charging the battery () of an electric vehicle, includes a primary side () with a primary pad () for generating a magnetic field () into the airgap () and a secondary side () arranged on the other side of the airgap () that picks up the magnetic field () and provides the energy received through the magnetic field () to the battery (). The primary side () is for example installed at a charging station and the secondary side () is comprised by the electric vehicle. In order to control the charging process during the power transfer, a wireless communication channel () is provided between the primary () and the secondary () by means of two wireless transceivers (). According to the invention, the wireless transceivers () are adapted such that their communication range is less than twice a largest spatial extent of the primary pad. In this way, the communication between the charging station and the vehicle may not be received by other charging stations or vehicles located at the same charging area. And if the other vehicles and other charging stations of the same charging area are adapted according to the invention as well, their communication does not interfere with each other or otherwise disturb each other such that a complex and laborious pairing process may be avoided.
