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 Mellon’s 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."
Any1 , agree with you that there are certain areas where gasoline stations are just ending up but what i think is it varies from city to city and country to country as well. In some aeas there is shortage of gasoline so definitely people will move towards EV but in some areas there is no shortage so people will prefer gasoline only . But no dount EV is the next upcomming technology which i guess no one can deny .
When it is not possible to charge at home, which will occasionally happen to almost everybody at least once, the solution would be to have a hybrid vehicle, so that it could charge with it's own generator. The other choice is for free enterprise to build charging stations to rent. I have also read about some city, not in the US, in which one must be able to prove that they have a parking spot before they are allowed to purchase a car. While it cewrtainly is a loss of freedom, it is one way to handle the parking problem.
Of course the same thing that prevents me from purchasing a propane fueled car ought to discourage folks from buying a car that they can never charge at home. But I am certain that the complaint will be that the government must do something to help the poor fools who did not think a bit ahead. Once again, the hybrid would seem to be the solution. Not that everybody would need one, but for some it will be the only smart choice.
In the city of New Orleans there were neighborhoods where very few owned cars because there was no place to park them. BUT it was no problem because they could take a bus any place they chose to go. The downside was no car to escape the flood with, and the city does flood every 80 years or so.
I agree that charging presents a serious challenge, William K. Battery-electric cars have always been assumed to be the solution for cities, in part because of EVs have such good fuel efficiency numbers in city traffic. The problem, though, is that crowded urban areas often have parking problems. Here in Chicago's urban neighborhoods, many people live in three-flats, which often have one small garage or no garage. So where does the EV owner charge up in those situations?
Bob, you are certainly right about the people finding a solution to make a buck.
But I disagree about it not being a tax. Every cent that the government chooses to take from me is a tax, period. If I CHOOSE to spend money for something that is different. But all of that which I have no choice about is a tax. Calling it something else is just a diversion. A pig is a pig, no matter how many times they call it a butterfly.
Isn't it just a simple matter of standards. All ev manufacturers standardize on the battery packs and how they are placed in the vehicle. Then it becomes am infrastructure change from gas station to battery swap out station.
I would not vote to spend public money to install charging stations to be used for private vehicles. There are arguments today suggesting that in addition to significant tax rebates and government refunds to enable the purchase of EVs, we should adopt a national policy of mandatory infrastructure upgrades to permit recharging of them. This, of course would not be a tax, but cities, towns, employers, and private parking lot owners would be fined if they fail to comply. For those who do not have a dedicated off-street parking space at home the options are limited but I believe where there is an opportunity for profit, someone will come up with a method.
Charging while parking ismindeed going to be a very large challenge in the proliferation of all plug in electric vehicles. But I wonder how many of those who would expect charging at work or in a public parking lot presently get their vehicle fuel tanks filled while they are parked? It certainly would be nice to have my tank filled while I am at work, but I don't think that many are that privaleged. Likewise in public parking lots.
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. Who else owes me a charge? IN addition, who else owes me the cost of my share of a public charging station? I don't believe that anybody is obligated to provide those for me, and I do imagine that such stations would be operated for profit by those willing to invest in them, much as gas stations today are mostly run for profit. Why should charging stations be any different?
So what we are discussing here is the unintended consequences of something that seems like a good idea, until the requirements for the supporting logistics come into play. The bottom line then is that folks should anticipate recharging at home, and not believe that anybody else is obligated to provide you with other options.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
As it does every year, Consumers Union recently surveyed its members on the reliability of their vehicles. This year, it collected data on approximately 1.1 million cars and trucks, categorizing the members’ likes and dislikes, not only of their vehicles, but of the vehicle sub-systems, as well.
