ABSTRACT
The article discusses electromagnetic compatibility (EMC) requirements for motor vehicles and their equipment and electromagnetic radiation (EMR) testing methods based on the normative documents that provide grounds for approving specific vehicle types for production and operation (type approval). The normative documents are UN ECE Regulation No 10 and Directive 72/245/EEC. Three groups of methods (line methods, area-related methods, and parameter estimation methods) have been proposed and described for the EMR assessment of vehicles. Based on the EMR tests carried out at PIMOT on a few electric vehicles (EV), the EMR of the vehicles was analysed and assessed with using some of the said methods. The following vehicles were used for the analyses and calculations: OPEL Ampera, RENAULT Fluence, CITROEN C-Zero, and MEGA e-City. The analysis and calculations carried out have revealed a close similarity between the usability of the proposed methods of EMR assessment of motor vehicles. The qualitative optimization of the parameters that can influence the assessment, primarily a reduction in the electromagnetic radiation (EMR) of the vehicle under consideration, will not only result in correct functioning of the vehicle, especially if it is electrically driven, but also will help to avoid possible harmful impact of EMR on vehicle occupants’ health. The work outputs may be utilized and disseminated, especially by the designers and researchers who are involved in work on motor vehicles, in particular EVs, where lots of electronic systems and modules are present.
