The Research and Safety Discussion of Electromagnetic Radiation in Electric Vehicles

To study the electromagnetic radiation in electric vehicles for human exposure, the electric field (6 Hz to 3 GHz) and magnetic field (6 Hz to 30 MHz) strengths in electric vehicles of driving mode, charging mode and stationary mode are measured, and the characteristics of the electric and magnetic field in electric vehicles are analysed and studied here. The studies show that the electromagnetic radiation of electric vehicles is mainly consisted of electromagnetic wave from 6 Hz to 500 Hz, and it might be higher in driving mode than that of charging mode and stationary mode. The abnormal values of electromagnetic radiation in electric vehicles often occur in driving mode, and usually appear in the front of the electric vehicles.
