System Tested in US Can Charge Electric Vehicles as they Drive

Officials in the American city of Detroit, Michigan, have equipped a piece of road with technology designed to charge electric vehicles (EVs) on the path.

The roadway is meant to serve as a demonstration¹ project for the technology, which could be expanded to larger road systems. Leaders of the project say it is believed to be the country's first public wireless² charging roadway built for EVs.

The system uses a series of copper³ wires placed underneath⁴ the road. These wires have the ability to send electricity through a magnetic field to charge an EV's battery. Charging can happen while the car is driving or sitting above the equipment.

The technology was created by an Israeli company called Electreon, a developer of wireless charging solutions for EVs. The company currently has contracts to build similar roadways in Israel, Sweden, Italy and Germany.

Stefan Tongur is Electreon's vice⁵ president of business development. He told The Associated Press EVs require special equipment to receive the wireless signal. "The technology is smart," Tongur said, and "knows who you are..."

The system was recently demonstrated to the public at a technology development center in Detroit. The center seeks solutions to transportation issues facing cities. The effort, which includes several development projects, is where Ford⁶ Motor Company is building a factory to develop self-driving vehicles.

The electrified⁷ road stretches about one half-kilometer. It will be used to test and improve the technology in preparation for wider releases, said Michigan's Department of Transportation (DOT).

Tongur said the project aims to "demonstrate how wireless charging unlocks widespread EV adoption⁸, addressing limited range, grid⁹ limitations, and battery size and costs."

He looks forward to a future in which, in his words, "EVs are the norm, not the exception."

Electreon says the electric road system is safe for people and animals walking over it and does not harm drivers.

Michigan's DOT signed a five-year agreement with Electreon to develop the roadway charging system. Officials have said they plan to build another electrified stretch of road in another part of the city.

American President Joe Biden is seeking to build a nationwide network of EV charging stations in the United States. His administration plans to establish at least a half-million sites along highways in the United States by 2030.

Michigan transportation officials say the wireless-charging roadway project has helped position the state and city of Detroit as national leaders in EV technology. "In Michigan, we want to stay ahead of the curve," Michigan DOT Director Bradley C. Wieferich told the AP. He added, "We want to lead the curve."
