Title: CHARGING STATION DEVICE WITH ONE OR MORE CHARGING STATIONS FOR AN INDUCTIVE CHARGING PROCESS
Abstract:
The invention relates to a charging station device with one or more charging stations (110, 111, 311) for wirelessly transmitting electric energy to a vehicle (100, 300). Each charging station (110, 111, 311) comprises a base unit (111) which is designed to generate an electromagnetic charging field during a charging process in order to transmit electric energy to the vehicle (100, 300) and a transmitting and/or receiving unit (323) which is designed to receive a request signal from a transmission unit (201) of a vehicle (100, 300) or to transmit the request signal to a receiving unit of the vehicle (100). The request signal lies in any range of a plurality of different frequency ranges. The receiving unit (323) is additionally designed to ascertain a signal strength of the received request signal. The charging station device additionally comprises a control and communication unit which is designed to transmit a message to a control unit of the vehicle (100, 300) and to a control unit of the receiving unit (323) of the charging station (110, 111, 311) selected for the charging process, wherein the message comprises information on which selected frequency range the request signal is to be transmitted in.
