In 2026, Florida will break floor on a freeway that may wirelessly cost EVs at pace in a small-scale take a look at that would have large implications for the way forward for mobility.
The freeway is definitely only a 3/4-mile portion of a bigger building mission, the 4.4-mile State Highway 516 (SR 516) Lake/Orange Expressway.
The Central Florida Expressway Authority (CFX) is constructing SR 516 in three segments. The primary one, as proven on the map beneath, will characteristic wi-fi charging know-how. The freeway can be open to the general public when it is completed in 2029, however the charging system will solely work on “specifically outfitted automobiles…for preliminary testing of the charging lane,” CFX says.

It stays to be seen if the mission will concentrate on charging vans or passenger automobiles; current assessments elsewhere have targeted on vans. In October, France activated a freeway that may wirelessly cost vans in partnership with Electreon, Fascinating Engineering stories.
In 2023, the state of Michigan additionally introduced that it had collaborated with Electreon to put in a quarter-mile wireless-charging public roadway in Detroit for testing functions. The Michigan Division of Transportation (MDOT) stated it deliberate to request bids in 2024 to rebuild a part of Michigan Avenue with inductive charging put in, however that doesn’t seem to have occurred.
In a significant milestone earlier this month, nonetheless, researchers at Purdue College accomplished the primary profitable wi-fi freeway charging take a look at within the US, in partnership with the Indiana Division of Transportation (INDOT). Their system charged a semi truck touring at 65mph, delivering 190 kilowatts of energy, or greater than sufficient for smaller automobiles as properly.
“This can be a system designed to work for the heaviest class of vans all the best way right down to passenger automobiles,” says Aaron Brovont, a analysis assistant professor in Purdue’s Elmore Household Faculty of Electrical and Pc Engineering.

Whereas wi-fi charging is widespread for smaller gadgets, corresponding to cellphones, it has not but turn into mainstream for electrical automobiles. Their bigger batteries pose an engineering problem, particularly when touring at excessive speeds on a freeway. “As a result of automobiles journey a lot quicker on highways than metropolis roads, they should be charged at greater energy ranges,” says Purdue.
Nevertheless, there isn’t any query that wi-fi charging could be an enchancment over wrangling with clunky energy cords. It is also simpler to make autonomous because the automobile can park itself over a pad and start powering up. That is seemingly why Tesla plans to wirelessly cost its future robotaxis. CEO Elon Musk remarked on stage in 2024 that it was “excessive time” the corporate made that change. In April 2025, Tesla stated it is also exploring wi-fi charging for its V4 Superchargers, however we’ve not seen any but.
Passively powering up whereas driving could be even higher—science fiction turned actuality.
