Regardless of the size of solar lamps, a charge and discharge control circuit with good performance is essential. In order to prolong the service life of the battery, its charging and discharging conditions must be limited to prevent the battery from being overcharged and deeply discharged. In addition, because the input energy of the solar photovoltaic power generation system is extremely unstable, the control of the battery charging in the photovoltaic power generation system is more complicated than the control of the ordinary battery charging. For the design of solar lamps, success and failure often depend on the success and failure of the charge and discharge control circuit. Without a well-performing charge-discharge control circuit, it is impossible to have a well-performing solar luminaire. The charge and discharge controller must have the following characteristics:
1. Anti-reverse charging control
2. Anti-overcharge control
3. Anti-overdischarge control
4. Temperature compensation
