Introduction
Electric vehicles will generate electromagnetic interference during conductive charging, which has a potential impact on radio service and power supply network. At the same time, electric vehicles may also be interfered by a variety of electromagnetic phenomena in the environment during conductive charging, resulting in charging failure and vehicle safety risk. This document gives the limits for electromagnetic interference, requirements of immunity and corresponding test methods during conductive charging of electric vehicles, which can promote the good control of electromagnetic environment and ensure the function and safety of conductive charging.
Electromagnetic compatibility requirements and test methods of electric vehicles in driving state have been specified in relevant standards. See GB/T 18387 (150kHz-30MHz) and GB 34660 (30MHz-1GHz) for radiation disturbance under driving conditions, and see GB 34660 for radiation immunity under driving conditions.
