摘　　要：为满足电动汽车日益发展的需要,其动力能源—蓄电池的充电技术必须能够实现快速、高效、无损的充电,采用变电流最优频率控制的脉冲充电方法,实现电动汽车动力蓄电池的智能充电。针对最优频率做了交流阻抗的实验,再现脉冲充电过程蓄电池阻抗—频率关系,实现蓄电池的内部阻抗在充电过程中与充电系统的输出阻抗匹配,找到电动汽车动力电池充电过程阻抗最小对应的频率段,即:脉冲充电过程的最优频率段,为脉冲充电过程的频率控制提供基本策略。The rechargeable technology of battery which is the dynamic energy of electric vehicles （EV）must be able to achievc last, efficient and non-destructive charge in order to meet the growing needs of electric vehicles. Based on the analysis and summary of a variety of charging methods and principles in the present, a charging method of a combination of optimal variable frequency contr,.! of the pulse charge is used to realize the charging of smart battery. In order to make internal impedance of the battery be matched with the output impedance of the charging system, impedance-frequency relationship of the battery in the process of pulse charging is reproduced in this paper by the experiment of AC impedance, and the frequency bands corresponding to minimum impedance in the charging process are found for the power batteries of electric vehicles. It is named as the optimal frequency bands of pulse charging process, and it can provide a basic controlling strategy of frequency control for the pulse charging process of system.
