Abstract
Recently, the deterioration of lead-acid battery for the automobile is one of the problems. Because, the electrical load increases in the recent automobile. In this paper, on-line SOH (State Of Health) estimation is proposed. The equivalent circuit constants vary by deterioration of the battery. The equivalent circuit constant can be estimated by using terminal voltage and current. Therefore, SOH can be estimated on-line.
