Comparison of EMF Exposure Limits and Assessment for Electric Vehicle Wireless Power Transfer*

Abstract

The electric and magnetic fields (EMF) generated by electric vehicle wireless power transfer might have health effects on the human inside and around the electric vehicle, including persons with active implantable medical devices. The comparative analysis on the EMF limits, measurement methods and assessment methods in the relevant EMF exposure standards were conducted, and the similarities and differences between domestic and foreign EMF standards and the international mainstream view were obtained. These provide the reference for the measurement and environmental impact assessment of electric vehicle wireless power transfer, as well as for revising Chinese national standard. The simulation and test research will be required with respect to the issues in the future, including assessment method of basic restrictions.
