Sistem Pengaturan Pengisian Baterai dengan Arduino Nano untuk Pembangkit Listrik Tenaga Bayu dan Panel Surya

Abstract

Research has been carried out on the design of a battery charging control device using wind and solar energy sources. The purpose of this research is to design a battery charging plan for PLTB and solar panels. By implementing a combination of renewable energy using wind turbines and solar panels with battery storage, this system is also known as a hybrid power plant. Then the electrical energy generated by the wind power generator and solar panels must be stored in the battery so that the energy can be used stably. In terms of charging the battery sometimes the battery is full but still connected to the battery charger. This will have a direct impact on the battery which will result in decreased battery performance. To prevent this, a system is created that automatically cuts off the flow of current to the battery when the battery is fully charged. Likewise, when the battery voltage is below the nominal, it is hoped that there will be a system that works automatically to charge the battery. In this research, a charging device was designed and a battery charging experiment was carried out on the 4th floor of the Department of Electrical Engineering, University of North Sumatra. The results showed that within 70 minutes charging the battery by the turbine reached 10.42 Volts, charging by the panel reached 11.02 Volts, and charging by the control sensor reached 12 Volts. Charging the battery using a panel or turbine takes longer when compared to charging using a control sensor. This is because the current value on the panel and turbine is smaller than the control sensor. On the panel it can be seen that the highest current is 0.78A, 0.06A for the turbine, and 1.03A for the control sensor.
