Electrically powered vehicle and method of charging an electrical energy storage device of an electrically powered vehicle

A method of operating a charging device of an electrically powered vehicle, the vehicle having a drive apparatus with an electric machine and an electrical energy storage device connected to the electric machine, the method comprising:

• receiving with the charging device energy from an alternating magnetic field by way of an electronic coil disposed to interact with the alternating magnetic field and to feed the energy to the electrical energy storage device in the form of electrical energy;
• setting the charging device with a settable compensating circuit connected to the electronic coil by the following steps:
• setting a power transferred to the charging device by the alternating magnetic field by adjusting a first adjustable capacitor of the compensating circuit connected in series with the electronic coil;
• and
• setting an efficiency level in relation to a power transferred by adjusting a second adjustable capacitor of the compensating circuit connected in parallel with a series connection formed of the electronic coil and the first capacitor.
