PROBLEM TO BE SOLVED: To output power to a main battery Bm side by operating a booster circuit 32a while avoiding excessive reduction of a charging rate of an auxiliary battery Ba under a situation in which generation power Psp of a solar panel 50 is determined in the course of events by a maximum power point tracking control being performed by an operation of a step-down converter 34.SOLUTION: A main battery Bm is charged by controlling output power Pbc of a booster circuit 32a at a command value Pbc* by a total amount of generation power Psp charged to a sub-battery Bsb being brought to a predetermined value or over. It is avoided that a charging rate of an auxiliary battery Ba is excessively reduced by controlling an output voltage Vdc of a DC/DC converter 70 at a command value Vdc*. |
