PROBLEM TO BE SOLVED: To provide a charger system capable of suppressing consumption of electric power as thermal energy when the electric power from a solar energy generator is charged into a storage battery, and suppressing wasting of electric power generated by the solar energy generator.SOLUTION: A charger system 1 includes a solar energy generator 10, a DC/AC converter 60 which converts the electric power from the solar energy generator 10 into an AC power, batteries 20, 30 for accumulating electric power from the solar energy generator 10, and a DC/DC converter 80 for converting a voltage of the electric power from the batteries 20, 30. The battery includes a main battery 20 and a sub battery 30 whose internal resistance is higher than the main battery 20.SELECTED DRAWING: Figure 1 |
