Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com, October 19 (Xinhua)-- A joint research group composed of nine companies, including the University of Tokyo, Chiba University, Bridgestone and Mitsui Real Estate, began the system experiment of wireless charging facilities for public road electric vehicles at the beginning of this month in the "Shibuya Intelligent New Town" in Shiba City, Chiba Prefecture, Japan, according to local reports by The Register and Nippon Keizai Shimbun on Tuesday.

According to the University of Tokyo, ▲, the project embeds transmission coils into the road at "key locations" such as traffic lights, because most vehicles at these locations drive slowly to facilitate charging. The facility is expected to add about one kilometer to an ordinary electric vehicle in 10 seconds.

In order to avoid wasting energy, the transmission coil is not always powered on, but is equipped with an induction system: the vehicle works only when the vehicle is close, and the minimum power can be kept on standby.

According to the official website of the New Field creation Science Research Department of the Graduate School of the University of Tokyo, the project has three key points: the realization of an on-the-way power supply system that can be used for all kinds of vehicles, the realization of a standardized on-the-way power supply system, and the development of road coils that can be used safely, transmit electricity and have high durability.

The test, which is expected to last until March 2025, includes the safety and durability of the equipment. If the test results are successful and in line with expectations, the local goal is to operate self-driving buses equipped with road-based wireless charging systems around 2030.

CTOnews.com previously reported that there have been a variety of similar studies and experiments at home and abroad. For example, on July 18, the Innovation Base of China FAW Research and Development Institute released a high-power dynamic wireless charging road system based on "5G + self-driving". The wireless charging road is 120 meters long. after driving on it, new energy electric vehicles can replenish electricity with a range of 1.3 kilometers.

▲ Touyuan CCTV News Stellantis also demonstrated the ability of dynamic wireless power transmission technology in the first half of this year to charge electric vehicles wirelessly when they are driving in a dedicated lane.
