Lead-acid battery system identification using experimental data

Resumo

© CSP - Cambridge, UK; I&S - Florida, USA, 2025.The goal of this research is to develop a battery model using experimental data gathered during the discharge of a lead-acid battery. It is essential to develop a mathematical model that accurately depicts the system in order to precisely describe the electrical characteristics of the battery and examine its discharge behavior while it is operating. The identification of an electrical model for a lead-acid battery using the data gathered in this manner is presented in this study. Jackey’s model was selected to depict the battery dynamics due to its resistive and capacitive properties, as well as the fact that it fits the experimental data well and has the advantage of being reasonably complex. The objective is to identify Jackey’s model parameters by using optimization techniques. In the end, the findings show that the selected mathematical model fairly depicts the system, which makes it a good substitute for lead-acid battery mathematical modeling.
