Patent ID: 8413439

Claim:
A combination, in a motor vehicle, of a micro-hybrid system and equipment on board the vehicle, the micro-hybrid system being able to function in recuperative braking mode, and comprising: at least one reversible rotary electric machine ( 1 ), an AC/DC converter ( 2 ), an auxiliary energy storage unit ( 4 ), a DC/DC converter ( 5 ), and one of an electrically assisted turbo-compressor ( 9 ) and a supercharger associated with the engine of the motor vehicle and supplied in pulse mode by a chopper ( 8 ); the one of the electrically assisted turbo-compressor ( 9 ) and the supercharger consuming for its dynamic functioning electric currents for periods of time; the micro-hybrid system being able, during phases of recuperative braking of the motor vehicle, to supply the auxiliary energy storage unit ( 4 ) so as to generate a dual voltage network which has a low voltage (Vb) to supply a battery ( 3 ) of the vehicle, and, at terminals of the auxiliary energy storage unit ( 4 ), a floating voltage (Vb+X) higher than the low voltage; the one of the electrically assisted turbo-compressor ( 9 ) and the supercharger is provided with response times by the floating voltage (Vb+X); the chopper ( 8 ) being supplied by the floating voltage (Vb+X).
