Abstract

The invention discloses a method and a system for testing the EMC (Electro-Magnetic Compatibility) of new energy vehicles. The test method comprises the following steps: A, presetting test condition parameters and receiver state; B, reading external noise, and saving noise obtained by spectrum scanning as basic external noise; and C, opening tested equipment, setting an object under test accordingto test conditions, reading current noise obtained by spectrum scanning, and performing operation on the current noise and the basic external noise to get the disturbance noise of the tested equipment. The aim of the invention is to test and rectify new energy vehicle products failing to pass EMC certification in the open field. As the background noise in the open field is extremely high, the background noise should be removed during vehicle EMC test and rectification in the open field. Therefore, the EMC of new energy vehicles can be tested accurately, EMC test and rectification in a vehicleplant is facilitated, economic waste is avoided, the cost is reduced, the certification cycle is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of EMC testing, in particular to a new energy vehicle EMC testing method and system. Background technique [0002] In order to reduce dependence on oil, promote energy conservation and emission reduction, promote the leapfrog development of the automobile industry and enhance international competitiveness, my country has classified the development of new energy vehicles as one of the major measures in the transportation field. At the same time, the compliance of new energy vehicles with relevant standards has also become a major focus of attention. In April 2016, the state mandated that newly declared new energy vehicles must comply with national standards for EMC (electromagnetic compatibility testing). Therefore, EMC testing and solutions for new energy vehicles have become an urgent problem for major automobile manufacturers and component suppliers. [0003] Many parts suppliers of OEMs attach great importance to...
