  • Chair: Masahiro Hanazawa (TAISEI)
Contents
In recent years, Wireless Power Transfer (WPT) technology has been rapidly moving toward practical use, particularly in applications for electric vehicles. At the same time, its potential applications are becoming increasingly diverse. In addition to high-efficiency power transfer circuits, magnetic field control, and EMC countermeasures, WPT is expanding into areas such as dynamic charging, mobile systems, industrial automation, and medical applications. This session will explore the latest trends in WPT technology, advancements in key components, and ongoing challenges and prospects toward social implementation and international standardization. Through presentations from both academia and industry, we aim to facilitate the exchange of knowledge that will contribute to the future expansion and application of WPT technologies.

Standardization and Regulation and System of WPT for e-mobility

Yukio Yokoi (Takushoku University)

Standaradization and Regulations and System for WPT of e-mobility(EV) should be mainly considered on wireless energy transfer via air-gap. Related organizations such as Radio Act in Japan, International organizations of ISO/IEC for IS, ITU of frequency management and CISPR on unnessesary radiation and others should be considered. This report pointed out current tasks and expected direction for Static and Dynamic WPT.

Potential of Aluminum Replacement in Wireless Power Transfer Sheet Type Coils

Sohma Hasegawa･Hitoshi Miyagawa･Hiroyuki Hase (Dai Nippon Printing)

This presentation will introduce the initiative to replace the material of sheet-type coils from copper to aluminum, considering the advantages of mass production, thinness, and lightweight design. It will examine the impact of this change on transmission performance and leakage magnetic fields, and present the findings of this investigation. The goal is to explore how this material substitution can enhance the performance and efficiency of wireless power transfer technologies.

Basic Study on Waveguide Power Transfer for Mobility Applications

Yuichi Masuda (2DC, Inc.)･Katsuhiro Hata (Shibaura Institute of Technology)

Waveguide Power Transfer propagates electromagnetic waves through a waveguide sheet installed along a route. A proximate receiver extracts power contactlessly, achieving continuous power supply with high positional freedom.
