Other challenges could slow down the electric road of the future. In this context, inroad charging while driving is unlikely to be a comprehensive solution for all-electric vehicles, said Jeremy J. Michalek, Professor of Engineering and Public Policy and Director, but it could play an important role for some applications. ” of the Vehicle Electrification Group at Carnegie Mellon University.
“For passenger cars, most drivers will leave the house with a full tank of power on most days, and the EV range is getting so large that most drivers won’t need public charging, except on days of rare long-distance travel. ” They said.
But there is an even bigger problem that such roadways can solve. “For long-distance trucking, inroad charging aims to address a real problem with electrified trucks,” said Mr. Michalek. Electric trailer trucks require large battery packs that reduce payload, Inroad charging can help, although traveling long distances will require a huge investment in infrastructure.
Inroad charging will also need to withstand “all the weight and weather abuse that tear down our roads today. There may be special applications where inroad charging infrastructure can be targeted at select locations, such as bus stops.” Or fleets with fixed routes and known stops,” he said.
The Purdue team is mindful of these challenges, but optimistic. “The technical barriers we need to overcome are not insurmountable,” Mr. Aliprantis said. “They can be overcome with proper design.”
However, there are regulatory hurdles, he said. “For example, in Indiana if you are not a utility, you cannot resell electricity. Therefore, if you are a roadway operator, you cannot charge vehicles for the electricity they consume. Also, there are barriers to using the interstate route to set up this infrastructure right now. There are some rules that need to be changed before they become a reality, at least in this country.”
In addition, the electric grid will need to increase capacity to guarantee that they can meet the demand that will be created. “Especially if we want to implement this technology on a large scale, because we’re not charging cellphones, we’re charging large vehicles moving at freeway speeds, which require significant amounts of electricity,” They said.
For the Purdue project, this is the beginning of a road trip.
“We see this technology as a great opportunity from the U.S. Department of Transportation and the Federal Highway Administration of Alternative Fuel Corridors to align it with major national roadways that offer plug-in electric vehicle charging, hydrogen, propane and natural gas fuels.” We support filling up with existing or planned infrastructure,” said Ms. Gakritza. “We are not proposing that all roads be 100 percent electrified.”
