Perancangan Dan Pembuatan SOC Balancing Batterai Pada Sistem DC MICROGRID

Batteries are utilized as energy storage media in DC Microgrid systems to store and distribute electrical energy that can be reused. However, issues such as overcharge and overdischarge can cause damage to the batteries. Therefore, monitoring and balancing the State of Charge (SoC) of the batteries is necessary to prevent imbalances that can be detrimental to the batteries. In this context, the reliable use of SMT125 VRLA 12V 5Ah batteries as the supply in DC Microgrid systems has been proven. Centralized control strategies and the use of balancing devices (balancers) are required to maintain the SoC balance of the batteries. Additionally, testing the converters and discharging the batteries result in graphs that illustrate the relationship between voltage, SoC, and time. Valuable information regarding discharge curves and optimal voltage levels to preserve battery performance is obtained from the test results. The findings also indicate that excessive discharge currents can significantly reduce battery capacity. Hence, operating the batteries within specific voltage intervals is necessary to maintain a constant current value. The importance of monitoring, SoC balancing, and proper operation in preserving battery performance and lifespan as energy storage media in DC Microgrid systems contributes to extended usage time and reliable power supply. Future developments could involve exploring other components and testing batteries on a larger scale than the DC Microgrid system.
