ELECTRICAL ENERGY STORAGE MODULE, ASSOCIATED SYSTEM AND METHOD

An electrical energy storage module is provided. The storage module includes a reversible electrical energy conversion device intended to be connected to an electrical energy source and an electrical energy storage device. The storage device includes a first branch including two filter capacitors in series, and a second branch including two identical electrical energy storage means connected in series. A node common to the two capacitors and a node common to the two energy storage means are coupled by an impedance. A first end of the first and second branches is connected to the electrical energy conversion device, and a second end of the first and second branches is connected to the electrical energy conversion device.
