Method for controlling a battery (20)-charging device (10), comprising a rectifier stage (11) with two DC power supply buses, at the output of each of which is connected a capacitor (C1, C2), each capacitor being coupled to an LLC resonant converter circuit (14, 16) of a DC-to-DC converter stage (12), each LLC circuit comprising a set of switches (140, 160) connected at input to one of the output capacitors and at output in series with a resonant circuit and with the first winding of a transformer, the second winding of the transformer being linked to a diode bridge (141, 161) linked to the battery (20). According to the method, for each LLC circuit: - a measurement of the voltage across the terminals of the capacitor is compared to a setpoint voltage; - the switching frequency of said set of switches is set according to the sign of the difference between the voltage across the terminals of the capacitor and the setpoint voltage.
