Other challenges may slow the electric road of the future. “To put this in context, inroad charging while driving is not likely to be a broad solution for all electric vehicles, but it could play an important role for some applications,” said Jeremy J. Michalek, professor of engineering and public policy and director of the vehicle electrification group at Carnegie Mellon University.
“For passenger cars, most drivers will leave home on most days with a full tank of electricity, and EV range is growing large enough that most drivers won’t need public charging except on rare long-distance travel days,” he said.
But there is a bigger problem that these kinds of roadways can solve. “For long-haul trucking, inroad charging aims to address a real problem with electrifying trucks,” Mr. Michalek said. Electric trailer trucks require large battery packs that reduce payload; inroad charging could help, though that amount of long-distance travel would require a huge investment in infrastructure.
