Solar energy is one kind of green clean energy, and non-environmental pollution. Recent year, how to use solar energy is very important also is the most active research area.
This topic introduces a kind of battery charger which use solar energy. The solar energy battery charger is use solar energy to charge electric energy. In this design, use CN3063 chip to control the process of charge. And in the system designed the protection circuit to avoid charging the tank depth surcharge to create own permanent injury.
