磷酸铁锂电池带负脉冲的快速充电方法的研究

摘要

Aimed at the slow charging speed of lithium iron phosphate battery with conventional charging methods, we propose a fast charging method with negative pulse discharge. Based on the feasibility analysis of charging with negative pulse,the size and time of positive and negative pulses are calculated and simulated. The experiment re-sults indicate that the charging method reduces the charging time compared with the conventional charging method.%以磷酸铁锂电池为研究对象,针对其在传统充电方法下充电速度慢的问题开展研究,提出了一种带负脉冲放电的快速充电方法.在分析了带负脉冲充电可行性的基础上,对其正脉冲和负脉冲的大小以及时间进行了具体的计算与仿真分析,结合实验测试数据证实该充电方法相比传统的充电方法确实缩短了充电时间.
