Abstract

The invention relates to a method for charging a vehicle battery by induction from a charging device including a charge transmitter including a primary coil Land an inverter capable of supplying the primary coil Lwith an AC supply voltage E. Said device also includes a charge receiver including a secondary coil Larranged in a vehicle. Said method consists of adjusting a frequency f of the power supply voltage (E) to the resonance frequency fo, when a motor vehicle is located in a parking space. Said method comprises the following steps: setting a first power-transmission parameter (E, f); starting an iterative test which consists of: setting a value of a second power-transmission parameter (E, f); varying the second power-transmission parameter (E, f) in a second authorized adjustment range; measuring the power (Pbat) transmitted between the charge transmitter and the charge receiver; determining if the power (Pbat) is no lower than a predetermined operating threshold (PObj); determining if the power (Pbat) increases; ending the iterative test if the transmitted power (Pbat) is higher than the predetermined operating threshold (PObj); setting the power supply voltage (E) in order to reach the measured transmitted power (Pbat), said first and second transmission parameters being set to the previously established value thereof.
