A method for contactless charging of the battery of an electric automobile by magnetic induction using a transmitter coil of a charging device and a receiver coil of the vehicle, the method including: controlling a power supply of a converter, at terminals of which the transmitter coil is connected, according to a variable frequency; measuring, in an analog circuit, a value of a current and of a voltage at the terminals of the transmission coil; calculating a phase shift between the current and the voltage; converting the phase shift into a digital value; and locking the variable frequency of the converter to the phase-shift value by digital processing.
