Will it work?
To help Michigan reach its goal of carbon neutrality by 2050, Governor Gretchen Whitmer announced last month that the state will construct the nation’s first wireless electric vehicle charging road — a one-mile stretch in the Metro Detroit area.
“Michigan was home to the first mile of paved road, and now we’re paving the way for the roads of tomorrow,” Whitmer said in a press release, “with innovative infrastructure that will support the economy and the environment.”
A wireless EV road works like this: As a car drives over it, the vehicle’s battery is charged by pads or coils built under the surface of the street using magnetic induction. It doesn’t give the car a full charge, but it helps add some additional mileage to a vehicle before its next complete powering up.
The project is still in the very early stages: The Michigan Department of Transportation began accepting proposals for the project on September 28. Until one is selected, it’s unknown exactly where the road will be, what it will look like, the precise cost, or how soon it could be operational. But some are questioning whether the project is worth it. Is it the best use of funds in a state with poor transit and crumbling infrastructure? And how will it even work, particularly in a place with harsh weather extremes like the Midwest?
“It’s just not feasible or economically viable,” said Chris Mi, chair of the electrical and computer engineering department at San Diego State University who is an expert on electric vehicle charging. A one-mile demonstration is doable, he told Grist, but at the larger scale there are several practical and economic barriers.
