Analyzing DC and AC Magnetic Field Intensity, Distribution, and Relationship in a Hyundai IONIQ 2016 Electric Vehicle

Abstract

This study aimed to evaluate the direct current (DC) and alternating current (AC) electromagnetic field (EMF) intensity and distribution of an electric vehicle (EV). The results revealed that the EV generated DC and AC EMFs, which differed depending on the operation (resting, idling, and driving at speeds of 40 and 80 km/h). A correlation was established between the AC and DC components of the EMF, which was approximately 0.5 when idling and 0.8 at speeds of 40 and 80 km/h. The results obtained were below the harmful limit set by regulatory agencies, specifically the International Commission on Non‐Ionizing Radiation Protection (ICNIRP) and the Institute of Electrical and Electronics Engineers (IEEE). To further contribute to this field of study, the various measurement equipment used in the literature are summarized according to their parameters.

Radiated Emission Prediction of a BLDC Motor Using High-Frequency Simulations

“…The electromagnetic compatibility (EMC) problems in electric motors and electronics of automobiles are getting increasingly noticed along with the rapid development of electric vehicles and self-driving technologies [1][2][3][4]. They include violated conducted emission (CE) and radiated emission (RE) levels over the CISPR-25 regulations, mostly caused by the faster switching speed of the motor driver as well as the increased number of electric motors.…”
