Determination of lead-acid battery capacity via mathematical modeling techniques

The evaluation of the ampere-hour capacity of a lead-acid battery using a mathematical modeling technique is presented. The battery model was used to simulate a battery cycle at different temperatures, at different rates of charge and discharge, and at different end voltages to determine how the battery parameter of ampere-hour capacity was affected. The parameter obtained from the model simulation was compared with experimental results for verification. It is shown that the mathematical model accurately depicts ampere-hour capacity under various operating conditions
