This paper aims to explore the optimal Li-ion battery charging frequency by using AC impedance technique. The experiment proves that the optimal charging frequency is the point of the minimum AC impedance. In such a situation of the battery charged by the optimal charging frequency, the charging time and charging efficiency are improved above 30.68% and 30.6%.
