摘　　要：针对大容量锂离子动力电池充电过程要快速高效同时保证电池寿命的要求,提出将大电流脉冲充电作为锂离子动力电池的快速充电方式。通过对电池大电流脉冲充电过程的大量试验,将其充电效果和恒流充电方式进行比较,证实了大电流脉冲充电是一种能有效减小极化现象、高效快速的充电方式。同时试验了不同脉冲时间、不同充电电流对脉冲充电效果的影响,得出最佳脉冲充电参数。The high-current pulse charging method is introduced as one of the quick and high efficiency charging methods. Through a great number of tests, the Li-ion battery can be charged faster and the charging efficiency improved observably compared to the constant-current charging method. In addition, on the basis of experiments, the effects of different pulse time and charging current on charge result were analyzed, thus the optimal pulse charging parameters were proposed.
