Patent Images
1. A driving apparatus supplying electric power to a starter motor coupled to a crankshaft of an engine mounted on a motor vehicle for driving the starter motor, and starting the engine with the starter motor, said driving apparatus comprising:
- a battery;
an engine starter for starting an engine with electric power from said battery;
boost control means connected to said battery for boosting electric power from said battery;
a large-capacitance capacitor connected to said boost control mean sand chargeable by the boosted electric power from said boost control means;
a starter switch connected to said battery parallel to said capacitor; and
energizing means for energizing said engine starter with electric energy stored in said capacitor when said starter switch is closed.

Abstract
An engine starter system for driving an engine starter with electric power from a battery mounted on a motor vehicle has a boost controller for boosting electric power from the battery and a large-capacitance capacitor which is charged by the electric power which is boosted by the boost controller. The engine starter is driven by the electric energy which is stored in the capacitor at a voltage higher than the voltage of the battery.
