Abstract

The growing population along with the socio-economic development has led to increased global electricity demand. Accordingly, there is a growing interest in PV systems as a viable solution to address this electricity shortage. Batteries play an important role not only in PV systems but also in the electrical and hybrid electric vehicle industries. Efficient power control and management of batteries are essential for ensuring the safety and optimal performance of PV systems and automotive industries. This paper has provided valuable insight into the charging process of lead-acid batteries across a wide range of states of charge (SOC%) to achieve significant improvements in battery technology and develop more efficient charging methods via the validation of the modified Thévenin model. The electric characteristics for the models were assessed as a function of SOC% to accurately represent battery performance while maintaining model simplicity, and enhancing model topology by establishing an accurate relationship between battery capacity or SOC% and voltage. Additionally, efforts were made to enhance the model topology by establishing an accurate relationship between battery capacity or SOC and voltage. The modified Thévenin model was experimentally validated on a 200 Ah lead acid battery at full charge (at approximately 100% SOC), resulting in a Root Mean Square Error (RMSE) of around 1%. This validates that the model effectively captures battery behavior across its entire operating range.
