Abstract

In this paper, an optimal charging strategy for lithiumion batteries is proposed to minimize the charging loss. In order to reach this target, a one-RC electric model is employed to model the loss for the battery, and an efficiency map is measured for the charger considering different charging currents and voltages. Dynamic programming (DP) algorithm is applied to determine the optimal charging current profiles for minimizing the losses of battery and charger separately and collectively. Experiment results prove that the proposed method is more efficient compared with constant current (CC) charging method without influencing the charging time.
