摘　　要：介绍了电动汽车高压电系统的集成结构,分析了安全管理中所需解决的问题,重点讨论了连接状态检测和绝缘状态检测。基于同步采样提出了连接状态在线检测方案以及绝缘状态在线检测方案,并进行了实验验证,给出了实验的测试结果,证明方案的有效性。The integrated structure and problems needed to be solved in high voltage system in electric vehicles were introduced. Great emphasis was placed on discussing connection state and insulation state, which were basic functions of high voltage management system. Methods of online monitoring of connection state and insulation state based on AD synchronous sampling were proposed. These methods were verified by experiments.
