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. |
