Abstract :
An independent solar cell control system operates without supply from an external commercial power source. The system usually consists of solar cells, a storage battery, a DC load and a control circuit. For systems of this kind, it is very important to equip them with a recharge and discharge function that can work efficiently in all seasons and a function with which to tell the battery operation status. This paper is to report on our study of battery recharge and discharge characteristics for designing a circuit that indicates remaining power in the solar-cell battery. The study also includes the developing of a method to design the said circuit, as well as primary performance and field tests on a trial product of the circuit we designed using that method
