CHARGING STATION FOR AN ELECTRICALLY POWERED VEHICLE AND CHARGING METHOD
First Claim
1. A charging station for transferring energy from the charging station to a wirelessly power-coupled electrically powered vehicle, the charging station comprising:
- a terminal for an electrical energy source;
an inverter connected to said terminal;
an electronic coil connected to said inverter and configured for providing energy by wireless energy-transfer coupling via an alternating magnetic field, said inverter being configured to apply an alternating electric voltage to said electronic coil in a resonance mode;
a detection unit configured to detect a malfunction relating to the transfer of energy during the wireless energy-transfer coupling of the electrically powered vehicle and to generate a malfunction signal; and
a control unit connected to said detection unit and configured to terminate an energy transfer by way of the alternating magnetic field based on the malfunction signal.

Abstract
A charging station transfers energy to an electrically powered vehicle which is wirelessly power-coupled to the charging station. The station has terminal for an electrical energy source, an inverter and an electronic coil connected to the inverter for providing energy for the wireless energy-transferring coupling by way of an alternating magnetic field. For that purpose the inverter is configured to apply an alternating electric voltage to the electronic coil in a resonance mode. The charging station has a detection unit and a control unit, the detection unit detects a malfunction relating to the transfer of energy during the wireless energy-transferring coupling of the electrically powered vehicle and to provide a fault signal. The control unit terminates the transfer of energy by way of the alternating magnetic field on the basis of the malfunction signal.
