An equalization system for batteries has two series-connected accumulator stages connected, each including an accumulator, a voltage generator including positive and negative poles, for each stage, an associated charging device supplied by the voltage generator. The charging device includes an inductor having a first and second ends, and a capacitor having first and second ends. The capacitor's first end connects to the generator's positive pole. It also has a diode whose anode connects to a negative pole of the accumulator stage and whose cathode connects to the inductor's first end. It also has a switch whose first end connects to the inductor. And it also has a control device that controls the generator and closes a switch of a charging device associated with an accumulator stage to be charged so that the inductor stores energy, and causes its transfer to that accumulator stage.
