摘　　要：介绍了锂离子电池的工作原理和快速充电基本原理,对锂离子电池的传统充电方法——五阶恒流充电方法和快速充电方法——五阶恒流快速充电方法进行了分析。按照连续正交技术确定了五阶恒流充电的最优充电模式,在此基础上确定了五阶恒流快速充电的充电模式,并对两种充电方法进行了仿真,结果表明两种充电方法都能够完成对锂离子电池的充电,加入放电脉冲可以增大充电电流的大小,增长大电流持续时间,从而实现了快速充电。The operating principle of lithium ion battery and the basic principle of fast charge were introduced.The traditional charging way of five-stage constant current method and the fast charge method of the five-stage constant current with negative pulse method in fact were analyzed.An optimal charging pattern of five-stage constant current method using consecutive orthogonal arrays was determined,which was the basis of the five-stage constant current fast charge method.Two charging methods were simulated,and the results show the methods are appropriate for lithium ion battery.In addition,the way with negative pulse can increase charge current,grow large current duration time,and thus realize the fast charge.
