Abstract
A method for determining the position of a charging station for wirelessly transferring electric energy to a vehicle, wherein the charging station comprises a ground unit with a primary coil configured to generate an electromagnetic charging field for transferring electric energy to the vehicle, and wherein the vehicle comprises a receiving unit of a satellite positioning system and a secondary coil in the vehicle underbody, comprises performing, by the receiving unit of the vehicle, a plurality of position determination operations for at least part of the duration of a charging process during which the vehicle is arranged with respect to the ground unit such that the secondary coil of the vehicle has a predefined positional relationship with respect to the primary coil of the ground unit. The method also includes determining spatial coordinates of the receiving unit of the vehicle from the plurality of position determination operations, and inferring spatial coordinates of the primary coil of the ground unit from the known position of the receiving unit relative to the secondary coil in the vehicle.
