Investigation of the electromagnetic field in electric and hybrid cars

Abstract

Electric and magnetic fields are present everywhere electricity flows. In electric vehicles, passengers sit very close to electrical system with significant power, usually for significant period of time. The relatively high currents achieved in these systems and the short distance between power devices and passengers mean that the latter are exposed to the relevant magnetic fields. In view of this, it is important to study the values of electromagnetic field parameters on board electric vehicles to ensure compatibility with international standards. The measurements were performed inside the four conventional vehicles under the standard condition. Data of international and Bulgarian standards for safe levels of electromagnetic fields are given. After the measurements, it was established that these levels were not exceeded.

Electromagnetic field in electric and hybrid cars

“…In the hybrid car, the magnetic induction values did not exceed 1.5 µT. In the next study, electromagnetic fields were measured in three electric and one hybrid vehicles [12]. The highest values of magnetic induction in an electric car were recorded in the Kia e-Soul.…”
