Comparison of magnetic induction emissions in electric, hybrid and conventional cars

The article analyses magnetic induction levels in vehicles with three different drive types: electric, hybrid, and conventional. The aim of the research was to determine the intensity of low-frequency magnetic fields generated by the drive systems and their effect on the driver and passengers of the vehicle. The paper describes methods for measuring magnetic induction at various locations within the vehicle, including the engine compartment and the power supply system. Measurements of magnetic induction were also performed during the charging of an electric car. The research results indicate that the highest magnetic induction occurs in electric cars and in the charging area during charging. In conventional drive cars, magnetic induction is mainly limited to the operation of the alternator. The power of the drive system significantly affects magnetic induction. In the case of measurements of magnetic flux density emitted by the power supply system and drive systems of fully electric and hybrid cars, the studies also showed that the location of elements such as the DC/AC converter and the cables connecting the converter to the electric motor and their distance from the driver's and passenger seats significantly affect their exposure level.
