Abstract:
1. A method for managing a power supply system ( 1 ) with a variable voltage (U), especially of a motor vehicle, said system ( 1 ) including, connected in parallel: at least one regulator ( at least one electrical energy storage element ( at least one load ( said method comprising, depending on the desired mode of functioning of said system ( setting, depending on said instantaneous rotational speed (N) of said machine ( setting, when said instantaneous rotational speed (N) is slower than said nominal rotational speed, said output voltage (U) to a first value substantially equal to said first service voltage and charging said storage element ( setting, when said instantaneous rotational speed (N) is faster than said nominal rotational speed, said output voltage (U) to a second value substantially equal to said second service voltage and charging said storage element (
