Abstract

Recently, the number of electric vehicles (EVs) is increasing due to the declining of oil resources and rising of greenhouse gas emission. However, EVs have not received wide acceptance by consumers due to the limitations of the stored energy and charging problems in batteries. The dynamic or in motion charging solution becomes a suitable choice to solve the battery related issues. Many researchers and vehicle manufacturers are working to develop an efficient charging system for EVs which is based on magnetic emissions to transfer power. These emissions must be evaluated and compared to limits specified by standards (in and outside the vehicle) in order to not cause harmful effects on their environment (humans, pets, electronic devices...). This paper presents an efficient method for modeling electromagnetic emission in near field and sizing a magnetic shield for a wireless power transfer (WPT) system for EVs. A model based on elementary magnetic dipoles is developed in order to obtain the same radiation as the real WPT coil. This model is used to size a magnetic shield which will be placed under the vehicle to protect human body from magnetic emissions. The obtained shielding plate allows to respect the standards of magnetic emission by bringing a decrease of 43 dB to the levels of magnetic fields. This approach is experimentally validated.

感应电动汽车充电系统磁屏蔽尺寸确定的有效方法

近年来，由于石油资源的减少和温室气体排放的增加，电动汽车的数量不断增加。然而，由于电池存储能量的限制和充电问题，电动汽车并没有得到消费者的广泛接受。动态或运动充电方案成为解决电池相关问题的合适选择。许多研究人员和汽车制造商正致力于开发一种基于磁发射传输电力的高效电动汽车充电系统。必须对这些排放物进行评估，并与标准规定的限值(车内和车外)进行比较，以免对环境(人类、宠物、电子设备……)造成有害影响。针对电动汽车无线电力传输系统，提出了一种有效的近场电磁发射建模和电磁屏蔽尺寸确定方法。为了获得与实际线圈相同的辐射，建立了基于初等磁偶极子的模型。该模型用于确定将放置在车辆下方的磁屏蔽的大小，以保护人体免受磁辐射的影响。所获得的屏蔽板允许通过使磁场水平降低43 dB来尊重磁发射标准。该方法经实验验证。
