摘要
为响应电动汽车快速充电要求，介绍了目前常用的几种充电方法，基于此提出了分段恒流结合脉冲充电的方法，并在Matlab／Simulink中对分段恒流结合脉冲充电方式进行仿真。实验表明：分段恒流结合脉冲充电方法能够极大削弱电池极化效应，在不损伤电池的前提下，缩短电池充电时间，提高充电效率。本实验结论可为锂电池快速充电技术提供理论依据。
In order to respond to the fast charging requirements of electric vehicles, several charging methods are introduced. Based on this, the method of segmented constant current combined with pulse charging is proposed, and the method is simulated in Matlab / Simulink. Experiments show that the method of segmented constant current combined with pulse charging can greatly weaken the polarization effect of the battery, shorten the charging time and improve the charging efficiency without damaging the battery. The conclusion of this experiment can provide the theoretical basis for the rapid charging technology of lithium battery.
