- Abstract
Institut Teknologi PLN or IT-PLN in Jakarta has a solar power plant with capacity of 28.8 kW, which is operated only for research and teching. Due to limited access to the facility only two observation points of data have been collected. One in 2018 and one in 2020. The data are state-of-charge (SoC) and state-of-health (SoH) of the battery with type of DB BSB 12-100 produced by BSB Power Co. Ltd. In 2018 the SoC is about 98.4% while the SoH is about 99%. In 2020 both parameters are 89% and 99%, respectively. Using a simple model consisted only of bulk capacitance Cbulk, surface capacitance Csurf, internal resistance Rint, and polarization resistance Rpol, we try to understand the obtained measurement values and use them to predict the working life of the battery. Since only two points of measurement, there could be a lot of solution will be obtained.
