Japan's R&D of radio-powered electric vehicles achieves 75% energy efficiency

Obstruction of the popularization of electric vehicles has two major obstacles: long charging times and short driving distances. To this end, South Korean scientists have come up with such a way - through electromagnetic induction from the ground to the car in real time transmission. Now, Masahiro Hanazawa from the Toyota Center Scientific Research Laboratory and Takashi Ohira of the Toyohashi University of Technology have developed a safer charging method - relying on radio frequency (RF) to charge the car.

It is understood that Hanazawa and Ohira have installed RF power in the metal tracks under the ground. A section of steel belt is installed in the car tires. When the electric vehicle runs on such a road, the metal track and the steel belt are There will be a capacitance between them, and at this point it will be able to draw power from the power supply below the ground.
It is reported that the prototype vehicle successfully completed its operation at a frequency of 52 MHz. The energy efficiency of the prototype is as high as 75%. The two researchers believe that this technology will greatly increase the cruise mileage of electric vehicles in the future. In theory, an electric vehicle driven by real-time driving will be able to continue driving and its required battery capacity is much smaller than what is currently used.
