Autonomous power supply system

摘要

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.

1. An autonomous power supply system for supplying electric power generated by a power generation element to a loading device, comprising:
a generation control circuit which controls power generation efficiency of the power generation element; a storage element group which charges the 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, wherein the storage element group includes a primary storage element for supplying electric power to the generation control circuit and the charging control circuit, and a secondary storage element for supplying electric power to the loading device; and the primary storage element is first charged with the electric power generated by the power generation element until a voltage of the primary storage element reaches a first predetermined threshold value, and when the first predetermined threshold value is reached, the secondary storage element is subsequently charged by charge supplied from the primary storage element until the voltage of the primary storage element reaches a second predetermined threshold value.
