Just in time for the annual Detroit Auto Show this week, IBM reports that Americans are intrigued by the possibility of driving an EV.

Thirty percent of U.S. drivers say they would consider switching to an all-electric vehicle, and 40 percent are willing to pay higher prices for an “EV,” a new survey from IBM finds.

Right now, 19 percent of the drivers in the survey said they are “very likely” or “likely” to put an EV on their shopping list for a new car.

However, many drivers are reluctant to invest the $1,000 or more than would be needed to up-fit their homes with an EV charging station. Only 13 percent are ready to foot the EV port upgrade.

IBM asked drivers if they were interested in moving to an EV that would get 100 miles or less per charge.

Buyers would pay as much as 20 percent more for an all-electric vehicle over a gas, diesel or hybrid vehicle with 27 percent willing to pay a 10 percent premium and 13 percent will to go up 20 percent.

However, the survey found that home charging capability is a crucial point in EV adoption since 83 percent of those surveyed park their cars in a garage or driveway.

Plus, two thirds of the drivers said would expect discounted charges for electricity if they charge their vehicles at home overnight.

“Even under optimal circumstances, fully recharging an electric-only vehicle takes hours,” said Kal Gyimesi, the co-author of the survey and accompanying study. “So, it is crucially important that we build an infrastructure that can charge vehicles where their owners park them for extended periods of time – whether that is at home or at work, school, or the store.”

In the same survey, automobile industry executives said they expect sales of conventionally powered vehicles to peak by 2020.
