Abstract :
This paper presents a method for diagnosing the degradation of the lead-acid battery unit. This method can diagnose the degradation of the lead-acid battery unit caused by internal short, opening of internal short or cell reversal. The salient feature of the proposed method is that the state-of-health (SOH) of the battery unit is estimated automatically at the end of each discharge cycle by measuring the battery voltage and current of a battery unit, so that no complicated measurement is required. To verify the proposed method, aging experiments for lead-acid battery are developed. Experimental results show that the proposed method can achieve expected performance.
