摘要
阐述了一种电动汽车用的动力蓄电池参数监控系统设计过程,详细讨论了其系统构成、工作过程以及蓄电池状态估计算法的实现。并结合台架试验对系统的实用性和准确性进行了验证。结果表明,应用本系统电池状态估计精度高,符合电动汽车对电池管理的要求。
A kind of battery parameter monitoring system(BPMS) used for electric vehicle(EV) is presented in this paper.The BPMS' construction and its working process are analyzed in detail as well as the realization of the state of charge(SOC) estimate algorithm.Finally,the serviceability and validity of the BPMS are proved via experiment.The result shows great accuracy of SOC estimated by BPMS,which is fit for the request of the electric vehicle well.
