連続中継送電コイルを利用した EV 用走行中非接触給電システムに関する検討

In recent years, the shift to electric vehicles (EVs) has become more prominent in many countries around the world. In line with this trend, research on systems that provide wireless power to running EVs is also underway in many countries. In order to realize this system, it is important to make the infrastructure easy and inexpensive, and one of the most important issues to be solved is to reduce the number of power sources used. We have proposed a repeater coil system as a power transmission method that can be expected to extend the power supply section per power source. In this paper, we discuss the usefulness of a series of repeater coils in a running wireless power transfer system, as well as their coil geometry and power supply characteristics.
