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