Abstract In recent years, the issue concerning electromagnetic radiation safety arising from the application of wireless power transmission system in charging electric vehicles has attracted wide attention. This paper constructed an electromagnetic simulation model of both the wireless power transmission system and the cardiac pacemaker and calculated the minimum safety distance under different power levels of the electric vehicle wireless charging system. The electromagnetic compatibility and thermal effect of the wireless power transmission system on the cardiac pacemaker was studied and analyzed. The simulation results show that,at different power levels and at their corresponding minimum safety distances, values of the cardiac pacemaker magnetic field strength are all less than the limit of 150 A/m, indicating that the wireless charging system of electric vehicles will not produce electromagnetic interference to the cardiac pacemaker. In addition, the maximum temperature rise of human body organs is all less than the 1℃. Thus, the electromagnetic thermal effect generated by the system will not cause harm to human body. Meanwhile, since the maximum temperature rise of the cardiac pacemaker is less than the prescribed 2℃, the thermal effect of the pacemaker generated under the electromagnetic radiation environment will not affect the system either.
