Most electric vehicles, or EVs, go less than a hundred miles on a single charge. So many EV owners stay close to home because they need to plug in overnight. But someday, wireless technology might recharge cars on the go – making plugging in obsolete.

The technology to recharge cars wirelessly already exists for a few EV models, but it’s not a factory-installed option.

And Omer Onar, an engineer at Oak Ridge National Laboratory, says the current technology is not very efficient.

So his lab developed new designs that make wireless-charging technology more powerful, efficient, and safer.

He says the system he’s developed will be tested first on vehicles that follow a set route and spend time loading and unloading at each stop – like shuttle busses and delivery trucks.

ONAR: “So we can actually take advantage and the vehicle can receive enough charge to make it to the next station, and in the next station it picks up charge again.”

Onar dreams of a time when highways are ultimately equipped with wireless charging stations strong enough to charge cars while they drive from place to place.

But in the meantime, as more wireless charging devices hit the market, the technology could make sales of EVs more competitive with traditional cars.
