Abstract
A charging station for an electrically powered vehicle has a connection for an electrical energy source, an inverter and an electronic coil connected to the inverter for wireless energy-transferring coupling of the electrically powered vehicle. The inverter is configured to apply an alternating electric voltage to the electronic coil in resonant operation. The electronic coil is connected to the inverter by way of a compensating circuit with a settable passive electronic energy storage device. The compensating circuit is configured to set a frequency of the alternating voltage by means of the settable passive electronic energy storage device.
Claims10
A charging station for an electrically powered vehicle, the charging station comprising:
- a connection for an electrical energy source and an inverter connected to said connection for the electrical energy source;
- an electronic coil configured for wireless energy-transfer coupling of the electrically powered vehicle;
- said inverter being configured to apply an alternating electric voltage to said electronic coil in resonant operation;
- and
- a compensating circuit having a settable passive electronic energy storage device, said compensating circuit connecting said electronic coil to said inverter, and said compensating circuit being configured to set a frequency of the alternating voltage by way of the said settable passive electronic energy storage device.
A method of operating a charging station for an electrically powered vehicle, wherein the charging station draws electrical energy via an inverter from an electrical energy source connected to the charging station, the method comprising:
- generating, with an inverter and an electronic coil connected to the inverter, an alternating voltage in resonant operation, to thereby provide with the electronic coil an alternating magnetic field for wireless energy-transfer coupling of the electrically powered vehicle;
- operating the electronic coil by way of a compensating circuit with a settable passive electronic energy storage device at the inverter for setting a frequency of the alternating voltage by way of the compensating circuit.
