Abstract (en)

[origin: FR2848033A1] The system has a primary network (7) of high voltage and a secondary network (10) of low voltage providing supply to a primary (8) and secondary electrical systems (11), respectively. The primary and secondary networks are coupled to respective batteries (6,9) of high and low voltage, respectively. A control unit (5) controls an average conversion electronic (12) that transfers energy between the networks, based on the states of the electric systems. An Independent claim is also included for a process for supplying two levels of voltages to the vehicle.
