Latest Invention: Technology that Allows Roads to Power EVs


If you like this invention, you can vote for it.

A team of Japanese researchers from Toyota Central R&D Labs and Toyohashi University of Technology was able to come up with a technology that would allow roads to charge electric cars.

They managed to invent a mid-drive charging system, which researchers claim to be the world's first. The system functions similarly to the mechanism that makes it possible for trains to run under overhead wires.

Currently the system is in experimental stage. It involves the use of electrified metal plates mounted under roads. These plates transmit energy through a radio frequency to a steel belt found in the tires of a car and another belt located above the tire.

According to the team, their invention would allow electric vehicle to be more lightweight than they are nowadays. EVs would require smaller batteries because roads would be the one to supply the majority of power to the motors, reports FastCompany.
