Session｜2026 JSAE Annual Congress (Spring)

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.

256	◯	Standardization and Regulation for WPT of e-Mobility -Trend of International and Domestic Standard and its Relations- 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.
257	◯	Practical Development of Wireless Power Transfer Inverters Haruki Aimi･Yoshio Tanai･Tatsuo Kataoka･Tsutomu Ishima (SPC Electronics) This reports on the development status of technologies for compliance with SAE (Society of Automotive Engineers) standards toward the practical implementation of wireless power transfer systems, the reduction of leakage magnetic fields from coils, and related technical challenges.
258	◯	Basic Study on Waveguide Power Transfer for Mobility Applications Yuichi Masuda (2DC)･Naoya Takahashi･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.
