Claims
- 1. A vehicular power supply apparatus for driving an engine starter by electrical power, said vehicular power supply apparatus being operatively connected to a battery for providing electrical power, said apparatus comprising:
- a large-capacity capacitor operatively connected to the battery;
- a starter switch operatively connected to the battery and in parallel with said large-capacity capacitor; and
- energizing means for delivering electric charge from said large-capacity capacitor to the engine starter in response to closure of said starter switch, said energizing means including a first electromagnetic relay including:
- a coil having first and second ends, the first end being operatively connected to said starter switch;
- first and second main contacts, the first main contact being operatively connected to said large-capacity capacitor and the second main contact being operatively connected to the engine starter; and
- a movable contact for connecting said first and second main contacts by energization of said coil.
- 2. The apparatus according to claim 1, wherein the second end of said coil is operatively connected to said second main contact.
- 3. The apparatus according to claim 1, wherein said large-capacity capacitor is connected in parallel with the battery.
- 4. The apparatus according to claim 1, further comprising:
- normally closed contacts operatively connecting the battery to the engine starter, and
- a second electromagnetic relay operatively connected to said first electromagnetic relay for opening said normally closed contacts.
- 5. The apparatus according to claim 4, wherein said large-capacity capacitor is connected in parallel with the battery.
- 6. A method for driving a motor with a vehicular power supply apparatus coupled to a battery and including a large-capacity capacitor, a starter switch having first and second positions, and a starter motor said method comprising the steps of:
- (a) switching the starter switch form the first position to the second position for starting of the motor;
- (b) supplying electric charge from the large-capacity capacitor to the starter motor when the starter switch is in the second position;
- (c) disconnecting the battery from the starter motor and the large-capacity capacitor when the starter switch is in the second position; and
- (d) charging the large-capacity capacitor using the battery when the starter switch is in the first position.
- 7. A vehicular power supply apparatus for driving an engine starter by electrical power, said vehicular power supply apparatus being operatively connected to a battery for providing electrical power, said apparatus comprising:
- a large-capacity capacitor operatively connected to the battery, said large-capacity capacitor being an electrical double layer capacitor;
- a starter switch operatively connected to the battery and in parallel with said large-capacity capacitor; and
- energizing means for delivering electric charge form said large-capacity capacitor to the engine starter in response to closure of said starter switch.
