Abstract：To achieve the highefficient and fast charge of a power lithiumion battery， a nondissipative charging method called as Reflex TM is adopted to remove the polarization phenomenon in the charging process. Based on the analysis of the optimizatio
n function of different charging current parameters on the charging process， the variablecurrent and variablefrequency control strategy is presented， and then a bidirectional DCDC converter and its control circuit are designed to implement the strategy. The feasibility and availability of the strategy is proved through the experiment where the positive and negative pulse amplitudes and the dutycycle are changed.
