Rocket scientists develop roads that charge electric vehicles on the go

If we are talking about electric vehicles, there is one problem that bothers us all. Autonomy anxiety, directly linked to the scarcity of electric vehicle charging infrastructure. But what if the electric vehicles can be charged during the race? What if the roads themselves could serve as EV chargers?

A group of researchers at Cornell University, led by Khurram Afridi, suggests that it may be possible for electric vehicles to be charged by the roads themselves while in operation, which will not only compensate for the scarcity of infrastructure. recharging, but will also reduce autonomy anxiety. good.

The technology used in this process is inductive charging, which is nothing new, at least not for automakers who increasingly allow smartphones to be charged wirelessly in their vehicles. The challenge is to apply the technology to the roads to generate the vast magnetic field to charge the vehicle, much like wirelessly charging a smartphone in a vehicle.

The use of this technology is not new, as it was also tested in California in the 1980s. However, alternating magnetic fields require expensive equipment, which requires more energy than the amount of energy required. ‘he gives. However, Cornwell researchers developed the technology using experience from NASA’s Jet Propulsion Lab. It uses high frequency electric fields instead of magnetic fields.

This technology would allow wireless charging of vehicles with a ground clearance of up to 18 centimeters. The road uses charging plates that could be built-in dozens of feet from each other, which will transfer power to vehicles, whenever EVs are driven on the road.

Researchers say high-frequency charging technology will charge a Nissan Leaf in four to five hours. An electric car with a bigger battery, like a Tesla, would take longer to fully charge.

Although this charging technology looks very interesting, it will require heavy and very expensive infrastructure to install. Although the technology is still in the research and development phase, it is not known when there will be an actual implementation.
