RANCANG BANGUN DAN PENGUJIAN SISTEM PENGISIAN SERTA PENGOSONGAN BATERAI JENIS LI – ION DAN LEAD – ACID DENGAN SUMBER PLTS

Abstract

As global energy demand increases and awareness of the environmental impacts of fossil fuels grows, the development of renewable energy sources such as Solar Power Plants (PLTS) becomes crucial. However, the intermittent nature of solar energy requires efficient energy storage systems. Batteries, specifically LithiumIon (Li-Ion) and Lead Acid types, become vital components in optimizing the utilization of solar energy. This research aims to design, build, and test the charging and discharging systems for Li-Ion and Lead Acid batteries using PLTS as the source, to gain a deep understanding of the characteristics of both types of batteries and to develop a system that can optimize their performance. The integration of power electronics technology and control systems will be implemented to enhance system efficiency. Based on testing and analysis, Li-Ion batteries show significant advantages over Lead Acid batteries for PLTS applications. Li-Ion has higher charging efficiency, greater depth of discharge, longer cycle life, faster charging times, and higher energy density. Li-Ion also performs more stably at high temperatures and, despite the higher initial cost, offers better economic value in the long term due to lower cost per cycle. This research is expected to make a significant contribution to the development of renewable energy storage technology, particularly in PLTS applications. The findings from this study can serve as a reference for practitioners and researchers in selecting and optimizing battery systems for future renewable energy applications.
