  • Electrical power system for an automobile vehicle
    Patent number: 6798166
    Abstract: The invention relates to an electrical power supply system for an automobile vehicle comprising an alternator, a first battery with a voltage less than the electromotive force of the alternator, and a second battery with a higher voltage. The first battery is charged while the inductance internal to the alternator is being charged and the second battery is charged while this internal inductance is being discharged. This system comprises for each alternator phase, a controlled switch in series with the first battery, and a diode to charge the second battery, and control means for each controlled switch such that the first battery is charged when this controlled switch is closed, and when the controlled switch is opened after the inductance has been charged, the inductance discharges into the second battery.
