Abstract: With the increasing of national infrastructure such as substations, power transmission networks, broadcast base stations and communication base stations in the natural environment, the electromagnetic environment is becoming more and more complex, and the rapid development of automobiles to electrification, intelligence and network connection requires more and more electronic and electrical support. Based on the fault case of an intelligent networked vehicle with power loss in a complex electromagnetic environment, the electromagnetic environment of the fault location is collected for playback simulation test in the vehicle electromagnetic magnetic compatibility, and the problem is accurately located because the static current of the vehicle exceeded the standard due to the influence of the electromagnetic environment on the air conditioning controller. The ignition circuit of the air conditioner controller is rectified through the electromagnetic magnetic compatibility test of the parts and the vehicle, so that the air conditioner controller passed the electromagnetic magnetic compatibility test certification of the parts and the vehicle. After the air conditioner controller passed the rectification test, it is repeatedly verified at the fault site after loading the vehicle, and the static current would not fluctuate abnormally, effectively solving the power loss problem of the vehicle affected by the electromagnetic environment.
