Dynamic Behavior of a Lead-Acid Battery based on State of Charge Estimation

Abstract

This paper presents a dynamic behavior of a Lead-Acid battery in order to achieve an accurate modeling which can be used for estimating the State Of Charge (SOC). On the basis of the high integration of the energy source for a variety of application, an experimental test- bench is developed and presented which contributes to well achieve a more comprehensive write-up of the studied problem. Then, based on Luenberger estimator, the SOC of the studied battery is well demonstrated in accordance with their real data. Taking into account the impact of the association of the battery under the global system in order to control the output power by meeting the needs of consumers, the dynamic behavior of the battery model is tested. Obtained results show a high level of accordance in terms of voltage and SOC of the battery with the lowest error value.
