To study the testing methods and issue diagnosis of high-voltage systems in new energy vehicles, this paper examines high-voltage electrical safety from two levels: equipment-level and vehicle-level and analyzes existing the high-voltage electrical safety regulations, standards, and the current technological status of new energy vehicles. The study also investigates the high-voltage insulation condition of new energy vehicles and corresponding protective measures, including the principles and testing methods of high-voltage insulation systems and monitoring systems. Finally, comprehensive solution for high-voltage electrical safety analysis, protection, design, and testing has been developed. This solution can perform exhaustive verification across various operating scenarios of new energy vehicles, enabling precise identification of system safety threshold violations and validation of operational safety, thereby simplifying the difficulty of issue diagnosis.

为研究新能源汽车高压系统的试验方法和问题的定位分析,从设备级和整车级2个层面研究了新能源汽车的高压电安全问题,分析了现有的新能源汽车高压电安全法规、标准以及技术现状,对新能源汽车的高压绝缘状态及相应的防护措施进行分析,包括高压绝缘系统的测试和监控系统的原理和测试方法。开发了一套高压电安全分析、防护及设计的方案和测试解决方案,可对新能源汽车的各个运行场景进行遍历验证,实现系统安全阈值超标问题的准确定位和操作过程安全性验证,简化问题定位难度。

To study the testing methods and issue diagnosis of high-voltage systems in new energy vehicles, this paper examines high-voltage electrical safety from two levels: equipment-level and vehicle-level and analyzes existing the high-voltage electrical safety regulations, standards, and the current technological status of new energy vehicles. The study also investigates the high-voltage insulation condition of new energy vehicles and corresponding protective measures, including the principles and testing methods of high-voltage insulation systems and monitoring systems. Finally, comprehensive solution for high-voltage electrical safety analysis, protection, design, and testing has been developed. This solution can perform exhaustive verification across various operating scenarios of new energy vehicles, enabling precise identification of system safety threshold violations and validation of operational safety, thereby simplifying the difficulty of issue diagnosis.
