This paper investigates discrepancies between the conducted emission test results of the On-Board Charger (OBC) and those of the vehicle-level alternating current charging system. Starting from the testing mechanisms, the paper systematically analyzes the correlation between the OBC’s electromagnetic interference characteristics and the vehicle-level test conditions. Through combined simulation and experimental validation, the paper proposes a component-level conducted emission interference control scheme. By ensuring component-level electromagnetic compatibility performance, the scheme enables pre-validation of vehicle-level standard requirements, thereby provides support for the forward development of electromagnetic compatibility in new energy vehicles.
