Thousands of electric cars could soon be rolling on Minnesota's roads, spurring discussions about how to keep them all juiced for long hauls from Austin to Alexandria or Blue Earth to Bemidji.
Still a novelty in the state, electric vehicles are poised at the edge of the mainstream with the coming release of several more affordable models boasting lengthy ranges. Minnesotans could buy a Chevrolet Bolt as of July 1, and the Tesla Model 3 began production this week — a year after dozens lined up at the Eden Prairie dealership to reserve one. Volvo announced Wednesday it would introduce only hybrid or electric models beginning in 2019.
"There is a sense that we're sort of on the cusp of exponential growth here," said David Thornton, an assistant commissioner of the Minnesota Pollution Control Agency (MPCA). The state has fewer than 5,000 plug-in electric cars today, and only about 1,600 of those rely solely on battery power.
The new models can travel more than 200 miles on a single charge, and most daily charging occurs at home. So rather than focusing on adding chargers in the metro area, the MPCA, the Minnesota Department of Transportation and others are plotting what's needed to make long-distance travel seamless, sketching out a statewide network of superfast roadside chargers.
"We're looking at what are the highest-traveled corridors that are connecting population centers where it might make sense to put more of these … fast chargers," said Tim Sexton, who works in MnDOT's environmental stewardship office. Sexton said they are trying to guide private investment instead of spending public money to install chargers.
Minnesota partnered with Wisconsin, Illinois, Indiana, Michigan and the city of Detroit this year to designate a stretch of Interstate 94 the "Great Lakes Zero Emission Corridor" and erect signs highlighting nearby electric charging options.
"You can, if you want, pretty effectively travel between these states in an electric vehicle with these longer range [models] that are coming out," Sexton said.
'Range anxiety'
There are nearly 270 electric car chargers for public use across Minnesota, with about a third of them clustered in Minneapolis and St. Paul, according to the U.S. Department of Energy. Many take hours to fully recharge a car, however.
