An ignition switch or starter PB initiates operation of the starter (5) through a control device (6). This energizes the starter relay (3) coil (11) through a diode (17). Should the drop in voltage due to the starter current reduce the voltage below a leve...

A capacitor system suitable for charging and discharging of a vehicle such as discharging due to starting of an engine, charging by an alternator, and recharging upon braking. The capacitor system can be a vehicle power source having several connected cell...

The starting system drives a starter motor (20) engaged to start an engine by using a (lithium) secondary battery (1) as a power source. A voltage sensor (9) detects a voltage at the secondary battery (1). A control device (10) allows power to be discharge...
