Abstract: This paper aims to explore the optimal charging frequency of the LiFePO4 battery by the analysis of the AC impedance. The experiments show that the optimal charging frequency is at the minimum AC impedance frequency fZmin . In such a condition, the LiFePO4 battery charging time and charging efficiency are improved about 5.6% and 6.8%, respectively. In addition, the increased temperature of the battery can be slowed down about 6.3℃, the aging phenomenon of the LiFePO4 battery can be reduced, and then the battery life cycle can be prolonged.
