摘要
为了确保电动汽车动力的安全运行并提高其故障管理的能力,设计了电动汽车动力电池信息服务系统,通过3G网络实现动力电池系统数据的远程交互,利用网络技术优势,提升系统安全监管水平并降低事故隐患.经试验验证,系统实现了远程数据交换、电池状态预估及历史数据后期处理等功能,传输过程中的丢包率不足2‰.系统在实现动力电池系统实时安全监管的同时,也有利于电动汽车的产品升级及运营管理.
In order to improve the fault management ability of the power battery system of electric vehicles and to ensure its safe running,a telematics system is proposed for the power battery system. In the telematics system,3G network is adopted to realize the remote interaction of the power battery system data,and the advantages of the network technology are utilized to improve safety supervision and reduce accident potentials. Experimental results show that（ 1） the proposed system has such functions as the remote data exchange,the battery state estimation and the history data processing;（ 2） the packet lost rate in the transmission is less than 2‰; and（ 3） the proposed system not only achieves the safety supervision of the power battery system but also benefits the product upgrade and operation management of electric vehicles.
