摘　　要：无线电能传输技术被广泛应用于电动汽车无线充电领域。该文建立了无线电能传输系统、人体及体内植入器件的仿真模型,完成了电动汽车无线充电系统对人体及体内植入器件的电磁安全研究。研究表明,人体在位于电动汽车无线充电系统三种不同位置处的人体平均比吸收率分别为1.7×10-3W·kg-1、0.067×10-3W·kg-1和6.2×10-3W·kg-1,均满足国际非电离辐射防护委员会导则的安全指标。人体器官与植入器件由于电磁热效应所导致的温升均低于人体正常自我调节阈值,说明人体在电动汽车无线充电过程中是安全的。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 selfregulation threshold,indicating that the human body is safe during wireless charging of electric vehicle.
