With the beginning of the fuel revolution, we will gradually reduce our dependence on gasoline and gradually shift to rechargeable battery technology. Therefore, electric vehicles have gradually begun to develop, but there is currently a key issue-how to drive electric vehicles What about charging?

The research team conducted tests on ordinary roads in Japan and showed that current can be transmitted through the road surface 6 inches thick
A number of electronic gas stations have been built along the roads in some countries and regions. A Japanese research team has proposed a new solution and successfully demonstrated how to charge a moving car through 12-inch thick concrete.
The research team of Toyohashi University of Science and Technology in Japan used special tires to charge cars on asphalt roads. The research team said that "electric cars on electrified roads" have not encountered technical obstacles in road driving.
Last Friday, the research team conducted tests on ordinary Japanese roads and showed that current can be transmitted through the road surface 6 inches thick. In the test, 50-60 watts of current were sent to a real tire, and a light bulb lit to show how the current passed through 6-inch thick concrete before entering a real-sized car tire.
Professor Takashi Ohir, the head of the study, said that it is no problem to enlarge the concrete thickness to 12 inches in the test, although this requires a voltage increase of 100 times to drive a car. He pointed out that there is no technical problem.
Takashi Ohir emphasized that the efficiency of power transmission through concrete is 80-90% or higher. At present, there are other companies focusing on the development of similar technologies. For example, Toyota Japan plans to add a metal plate system to the road.
