With the development of wireless power transmission technology, it was widely tried to apply in electric vehicle wireless charging field. This paper established the simulation model of wireless charging device, human organs and implanted devices, and completed the research on electromagnetic safety of human body and implanted devices in wireless system of electric vehicle. This paper show that the average specific absorption rate (SAR) of human body in three different positions of the electric vehicle wireless charging system is 1.7×10-3W·kg-1, 0.067×10-3W·kg-1 and 6.2×10-3W·kg-1, which meet the safety index of the ICNIRP guidelines. And the temperature rise of human organs and implanted devices due to the thermal effect of electromagnetic waves is lower than the human body's normal self-regulation threshold, indicating that the human body is safe during wireless charging of electric vehicle.
