摘要
提出一种最优频率控制的脉冲充电技术,用来改善电动汽车用动力电池的充电回应.建立了基本的数学模型,分析其工作原理,当用最优频率控制脉冲充电时电源与电池相匹配,输出的功率最大.通过分析可知:该方法不仅提高了充电效率,同时加快了充电速度.
This paper presents an optimal frequency control of the pulse charging technology to improve response to the electric vehicle battery charge, builds the basic mathematical model and analyzes its working principles. Results show that the output power reaches its peak and power supply matches battery. There fore, compared with the traditional method of charging, this method not only improves the efficiency of the
