Metal object detection for wireless charging of electric vehicles using planar coil array
针对电动汽车无线充电,有效检测充电区域内的金属异物对保障电动汽车的充电安全和充电效率具有重要意义.因此,文中提出了一种基于平面线圈阵列的金属异物检测新方法.利用4×4结构的平面线圈阵列作为主要感测元件,结合电磁层析成像技术重建充电区域的电导率分布图像,对重建图像进行后处理获得金属异物的轮廓、位置和数量信息.有限元仿真与实物实验结果表明,此方法能有效检测数种常见金属异物.
For the wireless charging of electric vehicles,metal object detection in the charging area is of great im-portance to ensure the charging safety and charging efficiency of electric vehicles.Therefore,a novel method is pro-posed for the metal object detection using the planar coil array.A planar array with 4×4 coils is designed as the main sensing element and images of the conductivity distribution in the charging area are reconstructed using the e-lectromagn…查看全部>>
