Modeling of the Lead-Acid Battery with Different Load Current Profiles

This paper presents the idea of modeling the Lead-acid battery for the changing Load current profile. A 12 V Lead-Acid battery was tested using the two different load profiles having amplitude 10 A. The small charging window was also kept to see the effect on the Sate of Charge (SoC) of the battery. The parameters of the battery like voltage variation, State of Charge –SoC, Depth of Charge (DoC) and Temperature in degree centigrade were also given the due consideration. The complete battery model was simulated in MATLAB/Simulink®. The total simulation time was 36000 second or 10 hours. The two different load profiles are considered to see the parameter variations.
