摘要

分析了近端金属物体对基于磁共振耦合的电动汽车无线充电系统能量传递效率的影响。实验和模拟结果表明，在接收线圈附近有金属铜片存在时，最佳能量传递效率发生了显著变化。这种对效率的影响也被认为是不同的物理间距之间的发射和接收线圈。结果表明，为了保持良好的能量传递效率，在每个可能的使用场景中，必须仔细考虑接收线圈附近金属物体的存在。

Effect of proximal metallic objects on the performance of wireless charging systems for electric vehicles

This paper analyzes the effect of proximal metallic objects on the energy transfer efficiency of magnetic resonance coupling based wireless charging systems for electric vehicles. It is observed from both the experiment and simulation that the optimum energy transfer efficiency changes dramatically in the presence of a metallic copper sheet in close proximity to the receiving coil. This effect on the efficiency is also seen to be different for different physical spacing between the transmitting and receiving coils. The results show that the presence of metallic objects in the vicinity of the receiving coil have to be carefully considered for each possible usage scenario in order to maintain good energy transfer efficiencies.
