This paper proposes a real-time algorithm is proposed for estimating the state-of-health (SOH) of lithiumion batteries based on current integration and constant-voltage (CV) charging time reset. The proposed method estimates SOH by comparing measured CV charging time with a reference value derived from the total cycle life specified by the battery manufacturer. The performance of the algorithm is validated through aging experiments conducted on LiFePO4 batteries.
