In the present invention, when charging both a high-voltage battery and a low-voltage battery by means of electrical power obtained by means of solar generation, by means of prioritizing the charging of the low-voltage battery over the charging of the high-voltage battery, a decrease in charging efficiency of the battery overall is suppressed. The vehicle-mounted power source device charges batteries by means of electrical power obtained by means of solar generation. A solar panel converts sunlight into electrical power. A DC/DC boost converter boosts the power converted by the solar panel. A control unit causes switching in a manner so that the high-voltage battery is charged by the electrical power boosted by the DC/DC boost converter when charging the low-voltage battery by means of the power converted by the solar panel and the amount of accumulated electrical power accumulated at the low-voltage battery is at least a predetermined value.
