Battery-powered vehicles may now face a different kind of stumbling block on the path to widespread acceptance. A new study from Carnegie Mellon University suggests that over the next 30 years, penetration of EVs into the national fleet will be curtailed if society doesn't first find a way to solve its parking problem.
Titled "US Residential Charging Potential for Electric Vehicles," the study contends that only 56% of vehicles now have a dedicated off-street parking space and just 47% have access at an owned residence. Those numbers are important, the study says, because consumers will be less inclined to buy EVs if they don't know where they'll charge them.
"Many consumers will be wary of making the extra investment if they can't plug in and charge at home," Jeremy Michalek, professor of mechanical engineering and public policy at Carnegie Mellon University, told Design News.
At least two studies have forecast EV adoption rates of 80%. A study by the Center for Entrepreneurship and Technology (blue line) predicts 80% by 2030. The Electric Power Research Institute (brown line) forecasts 80% by 2050. Carnegie Mellonís study, however, argues that changes will be needed to reach such numbers. Exceeding 22%, it said, calls for more residential infrastructure investment to increase access to home outlets. Exceeding 47% calls for chargers to be available to renters. To pass 56%, major changes will be needed in residential parking. (Source: Carnegie Mellon University)
In the long run, the problem could have a profound effect on the overall penetration of electric vehicle technology, which is projected by some studies to rise as high as 80% sometime between 2030 and 2050. Carnegie Mellon's study argues that just to reach beyond the 22% level, however, "would require residential infrastructure investment to increase access to outlets." Hitting 47% would necessitate additional accommodations, such as the availability of residential charging for renters.
In some cases, the accommodations could pose costly engineering challenges, Michalek told us. Bringing charging stations to public parking spaces could require laying of new electrical lines and possible addition of transmission equipment to handle the load. High-voltage fast chargers, which can recharge an EV battery in 20 minutes, might require costly special connections to the electrical grid, he said.
Michalek, who is a plug-in car owner, told Design News that he regularly deals with the charging conundrum. When he's able to secure a space near his home, he runs an extension cord out to his car. "Even then, it's not a great idea because the extension cord has to cross the sidewalk, creating a trip-hazard," he said.
Michalek contends that the parking challenge could affect sales of both battery-electric vehicles and plug-in hybrids, largely because both need to find a charging outlet. "Some adoption is happening now and that's great," he told us. "But this tells us that for electric vehicles to be a really big part of the solution, we're going to need some major changes."
"I guess these charging problems will not slow the rise of Evs. Definitely if someone is going for Electric vehicle he knows that he should keep the vehicle fully charged according to the daily requirement of commute ."
Debera, as long as customers have charging point at their home and office, no worries. Moreover, now a day's there are many charging stations too, so on the way, if needed it can be get charged. Charging point at parking lot is just like an added advantage.
"For urban dwellers, I especially like the idea of a plug-in hybrid. I believe there are many people in cities who could drive back and forth to work and use very little gasoline, but the gasoline would be there when needed. The advatage is that most of the commuting could still be electric."
Charles, am using a hybrid vehicle. So based on power requirement and situation, we can switch between this two sources for deriving maximum efficiency.
That's the problem in a nutshell, Monster69. To make it worse, costs of recharging stations could be high, especially the "fast charge" type. The New York Times reported in November that a "super speedy public charging station" could run $30,000. See link.

The most logical user of an electric vehicle is an urban dweller and the lack of a dedicated off or on street parking space could limit the ability to keep your vrhicle fully charged. While suburbanites with a dedicated space or garage can have some assurance of being able to charge their vehicle, utban dwellers may be parked far away from rheir power connection.
D.H. Almost every day I come across people who are quite devoid of that amount of sense that you mention. You are certainly correct that folks should know how much range they have left, and it is reasonable to expect that they should, but there are a lot who simply won't know and won't even understand how to know. They will believe that it is somebody else's responsibility to take care of that detail.
I guess these charging problems will not slow the rise of Evs. Definitely if someone is going for Electric vehicle he knows that he should keep the vehicle fully charged according to the daily requirement of commute .
"I, too, think the hybrid is a logical solution, William K, particularly so for those who don't have a place to charge at home."
Charles, exactly. Any vehicle runs on hybrid fuel has the advantage of switching between these two fuel source, as and when needed. My car is hybrid with petrol and gas. So when I require more power, I can switch to petrol and on plain surface to gas, which can yield more mileage.
"Common sense would dictate that one should plan to have enough fuel, or charge, to achieve the days driving, and then recharge at home. Indeed, I would not consider the purchase of an electric vehicle that was not capable of doing a day's commuting with an adequate margin of charge remaining."
William, exactly. Peoples has to charge enough either from home or work place for a break-less journey. Moreover there are many public charging stations are also there for charging EVs. Charging at parking lots are just like an added advantage and it's not mandatory that all parking lots has to be equipped with charging points.
Tesla Motorsí $35,000, 200-mile electric car may not revolutionize the auto industry by itself, but it could serve as a starting point for a long, steady climb to a day when half of the worldís vehicles will be plug-ins.
