A method for discharging an electrical energy storage unit of an electrical circuit includes a first switching system defining a DC/AC voltage converter and interposed between a first electrical sub-circuit, which includes the electrical energy storage unit and the electrical winding of the stator of a rotary electric machine. A second switching system defines a DC/DC voltage converter interposed between the first electrical sub-circuit and a second electrical sub-circuit. At least one electrical consumer forms part of the first electrical sub-circuit. The method includes detecting that the voltage across the terminals of the electrical energy storage unit exceeds a predefined threshold, and controlling at least one of the first switching system, the second switching system and the electrical consumer so as to reduce the voltage across the terminals of the electrical energy storage unit by circulating an additional current in the stator electrical winding, second switching system, or electrical consumer.
