A modest-looking, road-embedded wireless EV charging demonstration project could vault Indiana into the EV charging history books.
This photo shows construction happening May 1 on a quarter-mile segment that will be used for testing wireless power transfer to a heavy-duty electric truck as it drives across the pavement.
They don’t mean embedding solar panels in roadbeds, though. According to the research team, the potential for installing that technology at scale is somewhere off in the future. They mean solar canopies, which are already widely used in built infrastructure.The research team doesn’t address wireless EV charging, but they do make a compelling case for surmounting the challenges involved in erecting solar canopies over miles of highway.
“Covering Earth’s highways with solar roofs could generate 17.58 petawatt hours of electricity per year, equivalent to more than 60% of the world’s total electricity consumption in 2023,” emphasizes study lead author Lin Yao of the Chinese Academy of Sciences.The researchers also suggest that solar canopies could reduce traffic deaths by shielding drivers from inclement weather. Additional benefits could also be in play.
Wireless charging is also a better fit for an economy increasingly dominated by delivery and gig workers, who would save precious time whether using stationary or in-road wireless chargers. It’s also a plus for drivers with disabilities or anyone else who would rather stay inside their vehicle while charging.Where are all the wireless EV chargersall have road-embedded projects in the pipeline.
“The Purdue-designed wireless charging system is intended to work at power levels much higher than what has been demonstrated in the U.S. so far,” Purdue explains. “By accommodating the higher power needs for heavy-duty vehicles, the design is also able to support the lower power needs of other vehicle classes.”
