摘要
提出通过测量电动汽车直流系统正负母线对电底盘的电压来实时监测绝缘状况的方法。对影响测量精度的主要因素进行相应分析,并提出了提高精度的措施。设计了在线监测系统,并进行了实际装车试验。试验结果表明系统符合预期的设计精度要求,对故障情况可以及时报警,能够较好地完成实时监测电动汽车绝缘性能的任务。
An approach to on-line monitoring on insulation resistance in electric vehicle by measuring insulation voltage is proposed. The factors affecting measuring accuracy are analyzed and the measures for raising accuracy are put forward. The on-line monitoring system is designed and put on real vehicle for testing. Test results show that the system meets the expected requirements in design accuracy
