<p>A vehicle power-supply system includes a main power storage device that supplies power to a load circuit; a sub power storage device that outputs a voltage different from a voltage of the main power storage device and supplies power to an auxiliary device load circuit of the vehicle; a charging circuit that is connected between the main power storage device and the sub power storage device and charges the sub power storage device using power supplied from the main power storage device; and a control device that controls the charging circuit. The control device charges the sub power storage device via the charging circuit when a predetermined time elapses after a stop command for the vehicle power-supply system is entered, and stops the charging of the sub power storage device when a starting preparation for the vehicle power-supply system is detected.</p> |
