A joint research group consisting of the University of Tokyo, Chiba University, and nine companies including Bridgestone, Mitsui Fudosan, ROHM, and NSK will begin Japan's first demonstration experiment of in-motion power supply to electric vehicles at Kashiwa-no-ha Smart City in Kashiwa City, Chiba Prefecture.

 According to the University of Tokyo, the demonstration experiment will be conducted from October to March 10 under the direction of the Ministry of Land, Infrastructure, Transport and Tourism's ``on-site demonstration experiment of new road-related initiatives'' near the west exit of Kashiwa-no-ha Campus Station on the Tsukuba Express in Kashiwa City.

 The in-motion power supply system was developed by Professor Hiroshi Fujimoto and Associate Professor Osamu Shimizu of the Graduate School of Frontier Sciences at the University of Tokyo, and can supply power not only to electric vehicles but also to plug-in hybrid vehicles. A 10-second charge will enable a typical electric car to travel 1 km.

 If the power transmission coil on the road side is always energized, energy will be wasted when there is no vehicle on the power transmission coil, but the system is equipped with a system that minimizes standby power and enables vehicle detection in a short time.In order to use power transmission coils safely, they must have sufficient durability as a road surface and be capable of transmitting power.Therefore, the research group will use this experiment to verify the durability of a precast coil that integrates the power transmission coil and road surface.

 Electric vehicles are expected to become widely popular in the future as a measure to combat global warming and build a decarbonized society, but problems such as a lack of charging locations are being raised, and there is a need for social implementation of systems that can supply power while driving.
