This system for supplying (2) electrical energy to a motor vehicle comprises a grid (4), a first battery (8) connected to the grid (4) and having a first maximum no-load voltage, a second battery (10) connected to the grid (4) and having a second maximum no-load voltage strictly greater than the first maximum no-load voltage, a controllable alternator (6) connected to the grid (4) and capable of delivering an electrical energy, an electronic management unit (12) controlling a voltage of the electrical energy delivered by the alternator (6) during travel of the vehicle. The electronic management unit (12) successively imposes a first setpoint voltage strictly between the maximum no-load voltages, a second setpoint voltage strictly between the first maximum no-load voltage and the first setpoint voltage and a third setpoint voltage strictly less than the first maximum no-load voltage.
