随着中国电动汽车产业的快速普及与规模化发展，其电磁辐射骚扰问题日益凸显，且相较于传统燃油车更为突出，直接影响车辆运行的安全性与可靠性。为明确电动汽车电磁辐射骚扰的主要来源，本研究采用文献调研与实验室测试相结合的技术手段，对电动汽车关键电子器件及核心系统开展电磁兼容性（Electromagnetic Compatibility，EMC）专项研究与系统测试分析，进而提出针对性强、可落地的电磁辐射骚扰控制措施。研究结果可为电动汽车 EMC 设计优化提供可靠技术依据，对降低电磁辐射对车辆自身及周边环境的不利影响具有重要意义。

With the rapid popularization and large-scale development of China's electric vehicle industry, the problem of electromagnetic radiation interference from electric vehicles has become increasingly prominent, and it is more severe compared to traditional fuel vehicles, directly threatening the safety and reliability of vehicle operation. To clarify the main sources of electromagnetic radiation interference from electric vehicles, this study adopts a combination of literature research and laboratory testing techniques to conduct special research on Electromagnetic Compatibility (EMC) and system testing analysis on key electronic components and core systems of electric vehicles, and then proposes targeted and implementable measures for electromagnetic radiation interference control. The research results can provide reliable technical basis for the optimization of EMC design of electric vehicles and are of great significance for reducing the adverse effects of electromagnetic radiation on the vehicle itself and the surrounding environment.
