Title:
Independence electric power system
Document Type and Number:
Japanese Patent JP6018980
Kind Code:
B2
Abstract:
An autonomous power supply system includes a generation control circuit which controls power generation efficiency of a power generation element, a group of storage elements for charging electric power generated by the power generation element, and a charging control circuit which controls a charging operation and a discharging operation of the storage element group. The storage element group includes a primary storage element for supplying electric power to the generation control circuit and the charging control circuit, and secondary storage elements for supplying electric power to a loading device. The electric power generated by the power generation element charges the primary storage element preferentially, and the secondary storage elements subsequent to the primary storage element. A capacity value of the primary storage element is set to be smaller than a capacity value of the secondary storage elements.
