摘要
为增强电动汽车(EV)电池管理系统功能,提出一种基于无线射频(RF)网络的电池组在线监测和管理设计方案,通过无线网络的分布式控制,实现了对磷酸铁锂电池参数精确监测及数据传输等功能,并采用多种算法相结合对电池荷电状态(SOC)进行估算,提高了估算精度。实验结果表明:本系统能很好地对电池组进行实时动态监控和有效管理,为设计新型电动汽车电池管理系统提供了重要依据。
To improve the performance of battery management system for EV(electric vehicle),a distributed battery management system was developed on the basis of wireless transmission network of radio frequency(RF).The system functions for lithium iron phosphate battery included parameters accuracy monitoring,state of charge(SOC) estimation,data transmission as well as other extended components.Many SOC estimation methods were applied to improve the estimation precision.The experiment results prove that the system can fulfill the real-time requirement of both dynamic monitoring and high effective battery management,so that a major reference can be achieved for the design of EV battery management system.
