中文摘要：

传统燃油汽车的车载通讯网络管理方法己不能完全满足电动汽车需要，提出一种适用于电动汽车网络拓扑结构，它是由主网关、分网关和它们的子网络构成，子网络通过网关进行信息交互；划分了电动汽车的四种工作模式，网关根据当前工作模式分别控制各网络子模块的通讯状态，从而实现了局部式网络管理．这样既保证了电动汽车无间断安全监控，又最大限度降低了能耗．

英文摘要：

The network management of traditional vehicles cannot meet the requirement of Electrical Vehicles（EVs）. The paper proposes a network structure of EVs which compose of main gateway, sub-gateway and their sub network segments. Each network segments communicated with another by at least one gateway. 4 working mode of EVs are defined in this paper for the reason that gateway can separately control the state of its network segments, which reduce power consumption and increase the safety monitoring.
