摘要 近来,无线电能传输技术受到了越来越广泛的关注,同时,该技术也被尝试应用于电动汽车以实现电动汽车的无线充电。与能量在自由空间传播相比,电动汽车无线充电时的电磁环境有很大不同,而电磁安全问题也变得日益突出。基于上述问题,首先分析了该领域的安全限制与标准问题;其次通过仿真分析了电动汽车充电时的参数变化、电磁环境以及对人体的影响;最后通过电动汽车试验来验证仿真结果,系统实现了约为3.5 kW的能量传输。该研究可为无线充电电动汽车的优化设计提供理论依据。

Abstract:Nowadays,wireless power transfer increasingly catches a wide range of eyes and thus has been introduced into the area of electric vehicle(EV) so as to realize the wireless charging of EV batteries.Compared to the power transmission in free space,there are several differences in the electromagnetic environment when EV is charging and the electromagnetic security problem is becoming prominent.In this work,the margin of safety and the related standards are discussed first.In addition,the simulation is carried out to analyze the parametric variation,electromagnetic environment and their corresponding influences on human bodies.Finally,an experimental platform is built to verify the simulation results.The system realizes a wireless charging of EV with 3.5 kW power.The research can provide the theoretical basis for the optimization design of wireless charging electric cars.
