Abstract: The present invention relates to a method for transferring a charge from an electricity source to a battery means (21) of an electric device of a motor vehicle, said electric device including: a voltage converter (13) connected to the battery means (21), a capacitor connected to the voltage converter (13), a means for connecting the electric device, intended for being connected to the electricity source, a second voltage converter (14) connected between the first battery means (21) and the first converter (13) as well as to a second battery means (22). The method includes a step of connecting a means for connecting to the electricity source in order to enable a charge transfer towards the battery means (21). The method also includes a step of precharging the capacitor with a predetermined voltage from the voltage provided by the battery means (21) via the voltage converter (13), said precharging step being prior to the transfer of the charge from the electricity source to the battery means (21).
