The nation's first stretch of road to wirelessly charge electric vehicles while they're in motion will begin testing next year in Detroit.

Why it matters: "Electrified" roadways, which have wireless charging infrastructure under the asphalt, could keep EVs operating around the clock, with unlimited range — a big deal for transit buses, delivery vans, long-haul trucks and even future robotaxis.

Driving the news: Electreon Wireless, an Israeli company whose plug-free charging infrastructure is already being tested in Europe, will deploy its first U.S. pilot in Detroit's Michigan Central district, a new mobility innovation hub near downtown.

The big picture: Wireless EV charging is expected to grow to $827 million worldwide by 2027, says Meticulous Research.

How it works: Wireless EV charging systems use magnetic frequency to transfer power from coils buried underground to a receiver pad attached to the car's underbelly.

Between the lines: Wireless, or inductive, charging has multiple benefits over traditional EV plugs.

Yes, but: Wireless charging can add $3,000 to $4,000 to an already pricey EV, notes Meticulous Research.

Where it stands: President Biden is calling for 500,000 new public charging stations by the end of 2030, and Congress allocated $7.5 billion for EV charging in the $1.2 trillion infrastructure package passed last November.
