Detroit debuts America's first wireless charging road for electric vehicles

Detroit recently celebrated another milestone in automotive innovation by installing the nation's first electrified wireless-charging public roadway for electric vehicles. The Michigan Department of Transportation (MDOT) and the city of Detroit opened the segment of 14th Street in Detroit's Michigan Central as a "mobility innovation district," per Axios. The roadway will enable EVs to charge their vehicles without stopping to plug them in. 

Detroit has a reputation "around the world as the leader in transportation innovation," said Detroit Mayor Mike Duggan, according to a press release. Thanks to an initiative launched by Michigan Governor Gretchen Whitmer, the city "can add the nation's first wireless-charging public roadway to that list of innovations."

Paving the way for a 'zero-emission mobility future'

Gov. Whitmer announced the pilot initiative to develop America's first wireless charging infrastructure on a public road in September 2021, Detroit News reported. She reportedly said that the state will "electrify the d--- roads" in a prerecorded video. The city will use the quarter-mile stretch of road to test out and perfect the wireless-charging technology Electreon installed in a "real-world environment" before the technology becomes publicly available in the following years, per Axios. In 2024, Michigan will seek bids to rebuild part of US-12 (Michigan Avenue), where the city plans to install more inductive charging on another three-quarter-mile stretch.

Electreon and the Michigan Department of Transportation (MDOT) made a five-year commitment to create the electric road system. Electreon is an Israel-based developer of wireless charging for EVs, one of more than 60 tech and mobility startups participating in Detroit Newlab, "an innovation hub anchored by the once-dilapidated Michigan Central train station currently under renovation by Ford," Axios explained. The company is already testing its wireless charging tech in several cities in Europe, Israel and China. 

"Alongside Michigan's automotive expertise, we'll demonstrate how wireless charging unlocks widespread EV adoption, addressing limited range, grid limitations and battery size and costs," said Dr. Stefan Tongur, Electreon's vice president of business development. The initiative "paves the way for a zero-emission mobility future," Tongue mused, "where EVs are the norm, not the exception." 

A potential catalyst for widespread EV acceptance 

The work to complete the 14th Street experiment is expected to continue through the end of 2023, and testing is set to begin in early 2024, per the press release. Staff will use a Ford E-Transit electric commercial van equipped with the Electreon receiver to test the efficiency and operation of the vehicle "and study potential long-term public transportation opportunities."

Tongur suggested stoplights or bus stops as locations perfect for the technology. "That's because the tech requires each car to stay above the coils to actually charge," Car and Driver explained. If Electreon installed chargers at intersections where cars are stationary for long periods of time, "they can get more bang for their buck than if they install them along highways."

These electrified roadways could be "the catalyst to accelerate interest and acceptance of EVs for all consumers," said MDOT Director Bradley C. Wieferich. Making a reliable charging source widely available for EV users "without disrupting their commute supports both fleet operations and passenger travel," he added, noting that the initiatives are "leading us toward a more sustainable future with fewer emissions."

However promising the initiative might be, "there are some caveats in this technological rise for Detroiters," Emmet White wrote for Auto Week. The wireless charging technology needs a lot of setup before the average EV can use it: EV owners must install an Electreon receiver on their cars to trigger the inductive charging coils below the road surface. The estimated cost to install the receiver starts around $3,500, though Electreon aims to eventually cut those costs to around $1,500. "If buying an EV wasn't expensive enough, adding this receiver may only be worthwhile for a few localized owners, at least for now," White said. 

Electron and MDOT have not specified how much energy will be available, and it is unclear if "this public charging infrastructure will be free for use," he noted. And while some are excited about introducing electrified roads into the U.S. market, "it's worth remembering just how far the industry as a whole will have to move to make roadway charging effective."
