Abstract
An engine starting system for a vehicle includes a starter, a lead battery, an electric double layer capacitor which is connected in parallel with the lead battery, a starter switch and a control circuit for controlling current to the starter. The electric double layer capacitor is charged by the lead battery and discharge a large current to the starter when an engine is started. According to the construction of the control circuit, it is possible to control current discharged from the electric double layer capacitor so as to reduce damages on switches in the engine starting system. By using the electric double layer capacitor for the engine starting system, not only the burden on the lead battery at the engine starting can be reduced, but also the startingability of the engine can be improved.
