Abstract
Electromagnetic coupled resonant radio energy transmission is a new type of wireless power supply technology,which has the characteristics of high efficiency and long distance.An electromagnetic coupling resonant wireless charging system for electric vehicles is designed and its performance is analyzed experimentally.One to one coil transmission experiment shows that increasing the coil diameter and resonance frequency is helpful to obtain more transmitting power and reach a larger transmitting distance.The multi-direction electric energy receiving experiment shows that the optimized coil can make the receiving end receive energy from different directions,and provide the required electric energy for the electric vehicle sensor through the three-dimensional coil.The research is helpful to improve the long-distance endurance of electric vehicles and thus improve the driving efficiency.
