Fujimoto Laboratory, Graduate School of Frontier Sciences, The University of Tokyo, Nippon Seiko Co., Ltd., and Bridgestone Co., Ltd. have signed an agreement on a basic patent, and joint research on running wireless power supply for in-wheel motors installed in electric vehicles (EVs). I was supposed to enter.
According to Bridgestone, the joint research will be to directly supply power to the motor installed in the EV hall from the road surface while driving and stopping, and it will be possible to extend the mileage of the EV with a smaller battery. It also opens the way for weight reduction of the car body.
The University of Tokyo summarizes the concept of wireless power supply and is in charge of research and development of basic technology, NSK develops in-wheel motors with excellent mounting performance, and Bridgestone develops tires that achieve high efficiency in power transmission to in-wheel motors. Take charge. The three parties would like to proceed with the evaluation of vehicles including tires by 3 and shift to the demonstration experiment by 2022.
EVs are competing with automakers around the world to develop higher performance vehicles. The distance that can be traveled on a single charge is shorter than that of a gasoline-powered vehicle, and there are concerns that a shortage of battery supply will occur in the near future.The research group believes that the realization of wireless power supply can eliminate this anxiety.
