VEHICLE-MOUNTED POWER SOURCE DEVICE
First Claim
1. A vehicle-mounted power source apparatus that charges a battery with electrical power obtained by solar power generation, the apparatus comprising:
- a low voltage battery;
a high voltage battery that stores electrical power having a voltage higher than the low voltage battery;
a boost section that boosts the voltage of the electrical power for charging the high voltage battery;
a solar panel that converts sunlight into electrical power;
a bidirectional buck-boost section that boosts or steps down the voltage of the electrical power obtained through the conversion by the solar panel; and
a control section that makes a control so as to charge the low voltage battery with the electrical power transformed by the bidirectional buck-boost section, wherein,when the amount of electrical power stored in the low voltage battery is equal to or greater than a predetermined value, the control section makes a control so as to boost the electrical power stored in the low voltage battery, by the bidirectional buck-boost section and the boost section, and to charge the high voltage battery with the boosted electrical power.

Abstract
The vehicle-mounted power source device comprising: a low-voltage battery; a high-voltage battery; a boost unit that boosts electrical power for charging the high-voltage battery; a solar panel that converts solar light to electrical power; a bi-directional buck-boost unit that boosts/bucks the electrical power converted by the solar panel; and a control unit that performs control in a manner so as to charge the low-voltage battery by means of electrical power of which the voltage has been altered by the buck-boost unit. When the amount of stored electrical power at the low-voltage battery is at least a predetermined value, the control unit performs control in a manner so that the electrical power stored at the low-voltage battery is boosted by the boost unit and the bi-directional buck-boost unit, and the high-voltage battery is charged by means of the boosted electrical power.
