Abstract
A new solar cell charging system with fuzzy logic design is proposed in this study. This kind of solar energy storage system is
composed of a solar cell, a charger, batteries, a buck converter and a digital signal processor. In other words, it mainly
applies a low-voltage level translator to control the pulse charging current of a lead-acid battery and also combines the fuzzy
control method to improve the charging efficiency, suppress the abnormal temperature rise in the battery, lengthen the
battery life-time, reduce the additional waste, etc. Finally, the experimental and simulated results are shown to demonstrate
the validity of the system and verify the effectiveness with each other.
