Manufacturer-independent positioning system for inductive charging

摘要

The invention relates to a method and a corresponding device for positioning a vehicle over the ground unit of an inductive charging system. In particular, a charging station (110, 111, 311) for the wireless transmission of electrical energy to a vehicle (100, 300) is described. The charging station (110, 111, 311) comprises a ground unit (111) which is arranged to generate an electromagnetic charging field for the transmission of electrical energy to the vehicle (100, 300). Furthermore, the charging station (110, 111, 311) comprises a receiving unit (323) arranged to receive a request signal from a transmitting unit (201) of a vehicle (100, 300), the request signal being in any one of a plurality of different ones Frequency ranges lies. The receiving unit (323) is further configured to determine a signal strength of the received request signal.
