With the development of the domestic electromagnetic compatibility research on automobiles and their parts, major automobile research institutions, testing institutions, and automobile manufacturers’ automotive electromagnetic compatibility laboratories have also been completed one after another, as shown in Figure 1.11. Among them, in March 2001, the Electromagnetic Compatibility Testing Laboratory of the China Automotive Technology Research Center was formally certified and put into use, which marked that China’s automotive electromagnetic compatibility research has entered a new stage. The laboratory has a 10m electromagnetic anechoic chamber. (30.1 m×21.4 m×10.5 m) is the largest automotive anechoic chamber in China, a 3m method anechoic chamber, in addition to the open field, conduction shielding room, etc., the equipment conditions of the laboratory can meet most of the company’s research and development and testing Requirements ; In December 2004, the National Passenger Car Quality Supervision and Inspection Center (Chongqing) Electromagnetic Compatibility Laboratory officially

Completed, the laboratory is composed of 10m method and 5m method half/full anechoic chamber, shielding conduction room, power amplifier room and control room. It can complete related electromagnetic compatibility tests of motorcycles and parts and automobile parts and parts. And has carried out the EMC test of a number of 18m long articulated passenger cars and other large vehicles [49]; In 2010, the National Automobile Quality Supervision and Inspection Center (Xiangyang) Electromagnetic Compatibility Laboratory was formally established, which consists of a 10-meter full-vehicle anechoic chamber (22m× 15m×8m), 3m method parts test room, hub room, power amplifier room and control room, which can complete the conduction emission, radiation emission, conduction immunity and radiation immunity of the entire automobile and electronic and electrical parts And other related tests [50]; In January 2012, the electromagnetic compatibility laboratory of the National Automobile Quality Supervision and Inspection Center (Changchun) was officially put into use, mainly including a 10-meter anechoic chamber (26 m×19 m×8 m). ), 1 3m method component test darkroom, 1 shielding room, 2 amplifier rooms, 1 drum room and 2 control rooms, used for heavy, medium and light trucks, buses, cars and other automobiles and various electric The electromagnetic compatibility test of the whole vehicle and hybrid electric vehicle can also complete the electromagnetic emission (EMI) and immunity (EMS) measurement of automotive electronics and electrical components. It not only meets the automotive standard test requirements, but also meets the military standards and civil standards. Target test requirements [51]. In addition, such as Chongqing Changan Automobile Group, SAIC Motor, FAW Volkswagen, Shenzhen BYD Automobile and other large-scale automobile manufacturers’ automotive electromagnetic compatibility laboratory and Shanghai Tianxiang, Guangdong Rheinland, Kaiwei and other third-party testing institutions for electromagnetic compatibility Laboratories have also been built and put into use one after another. It can be found that the continuous improvement of laboratories and experimental equipment is also promoting the development of my country’s automotive electromagnetic compatibility research, and automotive electromagnetic compatibility practitioners have gradually acquired the ability of automotive electromagnetic compatibility design, analysis and rectification.
