摘　　要：近年来,无线电能传输系统应用于电动汽车充电过程中所产生的电磁辐射安全问题引起了广泛关注。该文构建了无线电能传输系统及心脏起搏器电磁仿真模型,并且计算了电动汽车无线充电系统不同功率等级下的最小安全距离,研究分析了无线电能传输系统对心脏起搏器的电磁兼容与热效应影响。仿真结果显示,不同功率等级下在其相应的最小安全距离处,心脏起搏器磁场强度值均小于磁场强度限值150A/m,说明电动汽车无线充电系统不会对心脏起搏器产生电磁干扰。人体各器官最大温升值均小于1℃,因此该系统所产生的电磁热效应不会对人体造成伤害,同时心脏起搏器的最大温升小于规定的2℃,因此心脏起搏器在该系统电磁辐射环境下所产生的热效应不会对其造成影响。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.
