Beschreibung
Zusammenfassung:	A method for contactless charging of a battery of an electric motor vehicle by magnetic induction using a transmitter coil of a charging device and a receiver coil of the vehicle, the method including: controlling electrical power supply and instructions of an inverter at terminals of which the transmitter coil is connected, according to a variable frequency; measuring, in an analog circuit, at least one analog signal relative to a current or to a voltage at terminals of the transmitter coil; digitally processing at least two incoming digital signals by a control board, a first incoming signal being relative to the voltage and a second incoming signal being relative to the current; transmitting output signals from the control board to the inverter to lock the inverter to a value of a phase difference calculated between the current and the voltage.
