Abstract
A vehicle-mounted power supply system that multiplexes power supplies in a vehicle and reliably supplies power of a voltage varying from a high voltage to a low voltage. The vehicle-mounted power supply system includes a primary power storage device, a secondary power storage device, and a power generation device. The primary power storage device has a high-voltage output terminal and a low-voltage output terminal. The power generation device supplies power to the primary power storage device and the secondary power storage device. The power supply system further includes: a first switch disposed between the power generation device and the primary power storage device; a second switch disposed between the power generation device and the secondary power storage device; and a third switch disposed between the low-voltage output terminal of the primary power storage device and the output terminal of the secondary power storage device.
