Abstract

This paper proposes a robust, intelligent constant current-constant voltage (CC-CV) charger for fast charging an aging Lithium-ion battery. Increasing the charging current in the CC regime cannot guarantee the short charging time, so an optimal charging current exists in the CC-CV method. The optimal charging current changes with battery degradation, so this paper figures out a way to find the optimal charging current by applying direct current internal resistance (DCIR) tests before the CC-CV charging method. The experiment results show that the proposed charger can adjust the optimal current based on battery state-of-health (SOH). The charging time has a 6.5% improvement when it is compared to a standard CC-CV fast charger.
