<p>PROBLEM TO BE SOLVED: To provide an automotive power supply system, which is employed in vehicles, such as route buses, etc., on which an idling-stop device is mounted, has a general-use battery (sub-battery) in addition to a starter battery, and enables a stable operation of a one-man-operated apparatus, while employing a simple construction. SOLUTION: A diode 8 (isolator) is provided between the connection point of an alternator 3 and a starting accumulator 1 to block a current from the battery 2 when a starter 4 is started, an electromagnetic switch 9 (bypass means) which makes the diode 8 (isolator) invalid is provided. The electromagnetic switch 9 is controlled by a control means 10, including a 1st electromagnetic relay 11, a 2nd electromagnetic relay 12, and an alternator build-up detection circuit 13, and the states of the starter 4 and the alternator 3 are decided.</p> |
