摘　　要：针对锂离子电池在充放电过程中的不同阶段以不同极化反应为主的特点,提出一种基于锂离子电池简单改进的等效电路模型的多级脉冲充电方式。同时,通过分析消除电池极化反应的机制,结合电池快速充电的基本原理,提出计算锂离子电池多级脉冲充电方式的最优充电模式的方法,为多级脉冲充电方式的科学合理性提供了理论依据和实验基础。与传统的多级恒流充电方式相比,锂离子电池的充电时间缩短13.3%,并有效提高了充电容量,减小充电能量。实验结果验证了所提出方法的有效性。In view of the fact that the lithium⁃ion battery has different polarization reactions in different stages of the process of charging and discharging,a multi⁃stage pulse charging method based on a simple and improved equivalent circuit model of lithium⁃ion battery is proposed.At the same time,the method of calculating the optimal charging mode of the multi⁃stage pulse charging for the lithium⁃ion battery is proposed by analyzing the mechanism of eliminating polarization reaction of the battery and combining the basic principle of battery quick charging.The theoretical and experimental basis for the scientificity and rationality of the multi⁃stage pulse charging mode is provided.Compared with the traditional multi⁃stage constant current charging method,the charging period of lithium⁃ion battery is shortened by 13.3%,the charging capacity is effectively increased,and the charging energy is reduced.The experimental results show that the proposed method is effective.
