| 摘 要： | 为降低电动汽车锂离子电池的充电损耗,提出了一种基于实时内阻测试的锂电池自适应电流充电策略。针对该充电策略中电池的实时内阻测试和最优电流集的求解问题,提出了一种电化学阻抗谱(EIS)检测法和随机进化算法。通过在MATLAB/Simulink中进行仿真实验,验证了算法的可行性。在不改变充电时间的情况下,文章所提出的充电策略比传统的恒流充电方法的减损效果更加显著。

| Abstract: | In order to reduce the charging loss of lithium-ion battery,an adaptive current charging strategy based on real-time internal resistance test is proposed.To solve the problems of real-time internal resistance test and optimal current set of the battery in the charging strategy,an electrochemical impedance spectroscopy(EIS)detection method and a random evolution algorithm are proposed.Through the simulation experiment in Matlab/Simulink,the feasibility of the algorithm is verified.Without changing the charging time,the loss reduction effect of the proposed charging strategy is more significant than that of the traditional constant current charging method. |
