Solar PV Charge Controller With Battery Management System Using Voltage Reference Control

Solar power is a great alternative to existing power sources. Global warming will lead to a lack of power sources soon. With the rapid increase of electrical power in the atmosphere, it is necessary to take strong steps to manage it. Solar power is affected by the weather. The development of solar charge controllers is therefore necessary. The solar charge controller connects the load between the photovoltaic panel and the battery. During the day, the PV panel supplies the load as well as charges the battery, and during the night, the battery supplies the load. By using the solar charge controller, the PV panel will operate at MPPT (Maximum Power Point Tracking), and the battery will be protected from damage (undercharging and overcharging) by checking its state of charge. Variable and constant DC supplies can be supported by the charge controller. DC nano grids, solar-powered electric vehicles, and thermoelectric modules for heating and cooling can benefit from this technology.
