Loss-Minimization-Based Charging Strategy for Lithium-Ion Battery

In this paper, an optimal charging strategy for lithium-ion batteries is proposed to minimize charging loss. 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. A dynamic programming algorithm is applied to determine the optimal charging current profiles for minimizing the losses of the battery and the charger separately and collectively. Experiment results prove that the proposed method is more efficient compared with a constant-current charging method without influencing the charging time.
