某纯电动汽车行车EMC问题分析与整改

Analysis and Rectifi cation of EMC Problems in a Certain Pure Electric Vehicle

在汽车电子电器化占比持续上升的趋势下,汽车EMC(电磁兼容性)问题研究越来越成为汽车行业的一大重要方向。本文通过对某纯电动汽车研发过程中一个EMC问题进行逐层分析,定位到根本原因为零件传导发射问题,说明了汽车EMC问题研究的重要性。

As the proportion of automotive electronics and electrical appliances continues to rise,research on automotive EMC(electromagnetic compatibility)issues has increasingly become an important direction in the automotive industry.This paper analyzes an EMC problem layer by layer in the research and development process of a pure electric vehicle,and locates the root cause of the conduction emission problem of the parts,which explains the importance of the research on the automotive EMC problem.
