Abstract
An electric power supply system for a starter comprises a capacitor. This capacitor is charged by a battery through a charging circuit including resistors that charges the capacitor by dividing a voltage of the battery by the resistors. This capacitor is discharged to the starter through a discharge circuit that applies to the starter a charged voltage of the capacitor in addition to the voltage of the battery. When the starter is driven, the connection of the capacitor is switched from the charging circuit to the discharging circuit by an ECU and switching relays.
Claims5
An electric power supply system for an electric load of a vehicle having a battery, comprising:
- a capacitor;
- a charging circuit including resistors that charges the capacitor by dividing a voltage of the battery by the resistors;
- a discharge circuit that applies to the electric load a charged voltage of the capacitor in addition to the voltage of the battery, wherein the discharge circuit is composed of a series circuit of the battery, the capacitor and the electric load;
- and
- control means that switches connection of the capacitor from the charging circuit to the discharging circuit.
