Other challenges could slow down the electric road of the future. “To put this in context, on-road charging is unlikely to be a comprehensive solution for all electric vehicles, but it could play an important role for some applications,” said Jeremy J. Michalek, professor of engineering and public order Director of the Vehicle Electrification Group at Carnegie Mellon University.

“With cars, most drivers will leave the house with a full tank of electricity on most days, and the range of electric vehicles will be so great that most drivers will not need to top up publicly except on rare days of long-distance travel,” he said.

But there is one bigger problem that these types of roads can solve. “For long-haul transport, in-road charging aims to solve a real problem in the electrification of trucks,” said Michalek. Electric trailers require large battery packs that Reduce payload; In-road tolls could help, although that amount of long-distance travel would require huge infrastructure investments.

Charging on the road must also “withstand all the weight and weather conditions that tear our roads apart today. There may be certain applications where the road charging infrastructure could be targeted at selected locations, such as bus stops or fleets with fixed routes and known stops, ”he said.

The Purdue team is aware of these challenges but is optimistic. “The technical obstacles that we have to overcome are not insurmountable,” said Aliprantis. “These can be overcome with the right design.”

However, there are regulatory hurdles, he said. “For example, if you’re not a utility in Indiana, you can’t resell electricity. So if you are the road operator, you cannot charge the vehicles for the electricity they use. In addition, there are currently barriers to using interstate rights of way to install this infrastructure. There are certain regulations that have to change before this becomes a reality, at least in this country. “

In addition, the power grids need to increase their capacity to ensure that they can meet the needs that arise. “Especially if we want to implement this technology on a large scale because we are not charging cell phones, but rather large vehicles moving at highway speeds that use a significant amount of electricity,” he said.

For the Purdue project, it is the starting signal for the road trip.

“We see this technology as a great opportunity to align the US Department of Transportation and the Federal Highway Administration’s vision of alternative fuel corridors along major national roads that allow electric vehicle charging, hydrogen, propane, and natural gas support. “with existing or planned infrastructure“, said Ms. Gkritza. “We are not suggesting that all roads be 100 percent electrified.”
