According to the U.S. media autoevolution, June 5, researchers at the University of Tokyo in Japan recently developed "the world's first in-wheel radio system" and put it into trial. It is reported that this new system can be directly incorporated into the motor vehicle wheels. According to the experiment shows that the maximum power of this motor designed by scientists at Jingdong University is 3 kilowatts. Simply put, is the wireless transmission of power from the car power coil connected to the hub, the rear wheel drive electric test car can be 75 km / h speed. This can not help but think of this year's Shanghai auto show Chevrolet FNR concept car. Hiroshi Fujimoto, an associate professor at the University of Tokyo, said: "This technology will open the way for advanced electric vehicle development, providing wireless charging on the road and also for fuel cell vehicles and industrial machinery."
