The Future of Roadway Electrification
In late 2025, a system designed by engineers at Purdue University delivered 190kW to a battery in a truck traveling 65-mph on a quarter-mile stretch of U.S. Highway 52 in West Lafayette, Ind. A Cummins prototype Class 8 electric semi-tractor was outfitted with a single receiver coil that took the charge from a web of transmitter coils installed below concrete highway pavement by the Indiana Department of Transportation. The successful test, Purdue says, is a milestone in dynamic charging research because it shows that it is conceivable to deliver the higher power levels required for charging the batteries of heavy-duty trucks as they move down the road. The power delivered by the Purdue system in the test far exceeds that delivered in other dynamic wireless charging tests that have focused on less demanding lighter-duty vehicles, opening the door to a future where heavy-duty trucks could be equipped with a single receiver coil and smaller, lighter batteries capable of being dynamically charged.
