Charging an Electric Vehicle In Public Can Cost Triple What Fueling Up a “Gas-Guzzler” Does

Public EV charging can be ridiculously expensive. Here is what we paid to add 34 miles to a new 2022 model year EV at an EVgo charger.

Charging an electric vehicle in public can range in price from free to very expensive. When we recently charged a new 2022 Chevrolet Bolt at an EVgo DC fast charger (DCFC) in Bedford, NH, we discover the pricey end of the spectrum can be more than it would cost to fuel a "gas-guzzling" V8-powered muscle car.

We charged up a Chevy Bolt using the EVgo DC fast charger, and the bill was $10.15. That amount of money added 34 miles of range to the Bolt. So, the cost per mile of energy was 30 cents per mile. Let’s compare that to a 2021 Dodge performance car we tested the prior week.

The Dodge had 797 hp, and it returned a combined fuel mileage of 24 MPG in our use on the same route we tested the Bolt. We paid $2.90 per gallon for the gasoline it uses. Doing some “goes in’tahs,” the cost per mile for energy in the muscle car turns out to be 12 cents. Thus, the cost per mile to energize the Bolt was roughly triple what the V8 gas-powered car cost us.

When charging in public one is supposed to quit charging when one’s EV reaches 80% state of charge. The reasons for this are two-fold. First, the rate at which charge can be added to an EV battery is more rapid below 80% and much more time-consuming as the battery reaches full. Second, EV chargers are in very short supply. We need to ration them.

On my route from the metro Boston area to the lakes region of New Hampshire, there are exactly zero public DC fast chargers. In order to charge at a DCFC, I took a slightly longer by time route to swing by one of only two DCFC charging spots in that area. Google “Henniker NH DC Fast Chargers” if you want to see what I mean about no chargers. I needed to top-off in order to complete the 200+-mile route I was making. So, I broke charger etiquette, and I charged to full.

I also charged at the DCFC because I wanted to test my EVgo membership RFID card and account and see how long the DCFC took to add back miles. Both were successful tests.

Charging For Free
Coincidental to my test, GM was running a free-to-charge promotion day during the week I had the Bolt. I think free anything is great, but I always wonder, what’s the hidden agenda? If charging up an EV is very affordable anyway, why does there need to be a promotion to make it “free?” If Dodge offered free gas to muscle car owners, I suppose folks would jump at the chance for a free fillup. But why make EV charging free?

Chevy Bolt charging poll image by John Goreham

The answer is to get EV owners to the chargers and have them try out the experience. You see, when we poll owners of EVs, most report that they only charge at home, and almost none report using DC fast chargers.
When I plugged into the EVgo DC fast charger, I hadn’t thought about the cost. After all, we constantly hear how affordable EVs are to power up. I have done the math at my own home, and I know that the cost is typically about five to seven cents per mile of range I add back on my home charger using my relatively pricey Boston-area electricity. $10.15 for just 34 miles was a “shock.” Get it, shock. Bet you never heard that in an EV story before.

Really, THE most nefarious? More than China, Russia, and India? More nefarious than Mexico, Columbia, Venezuela, South Africa? You can always move to another nation if you don't like it here.

If you think the only carbon emissions cost comes from driving these you are sadly mistaken. If we start to consider the big picture ie the carbon cost associated with manufacturing and disposal things start to look a little more even. If we truly want to be environmentally conscious then study after study have shown no matter what u chooses to drive if far better for the planet to buy it and run it for 15-20 years bot throw it away and buy new every 2

We shouldn't be throwing out nearly as much, obviously, but there are plenty of people happy to give your jalopy an extended life until it rusts to the point of unusable or is so out of date that the insurance and inefficiency outweighs a reduced "used" price, which is often 30 or more years if no owners do the disservice of significantly and rapidly altering the structure of the vehicle. Frankly, if you have the resources for a new vehicle, you should be buying electric and trading in the old unless it honestly won't work for you, because your vehicle WILL find a second life with someone else, and if you buy electric you at least begin the transition.

Also, by the way, every serious study puts the lifetime carbon emissions of an electric vehicle in all but the very worst cases as well below the lifetime emissions of even the best ICE vehicles. That's counting manufacturing. So unless you are looking for something to wrap around a tree, the investment in an EV is an investment in combatting climate change.

And if you just really hate the idea of a new car, there is a healthy market for used EV's that may not have the range but certainly have some spunk. So if you are part of the vast majority of drivers who could probably bike commute but have some excuse not to, a used EV should be fine for most or even all trips.

Thank you, Sean. As you say, the comparison is ridiculous and just helps to highlight the issue of how EV charging is not a no-brainer. We need to plan and think in order to do it sensibly and affordably. And the fraction of Americans with 800 hp vehicles is minuscule. A rounding error when it comes to the vehicles in service today.

Let's not pretend the EVs aren't without thier own moral dilemmas. I'm all for green energy, but the stories from African mining operations are discouraging. Our hunger for modern batteries comes with it's own price in blood.

Not just African mining. When it comes to mass production of hybrid and electric vehicles, the main problem has been a shortage of batteries. (Edited for content. Point is there is a coast to manufacturing batteries)

Lithium is the 33rd most abundant element, however, it does not naturally occur in its pure form due to its high reactivity. Lithium metal, due to its alkaline properties, is corrosive and reacts with water. Breathing lithium dust or alkaline lithium compounds irritates respiratory tracts. Prolonged exposure to lithium can cause fluid to build-up in the lungs, leading to pulmonary edema. The metal itself is a handling hazard because of the caustic hydroxide produced when it is in contact with water causing an explosion.

Lithium mining carries high environmental costs. Mining companies prospecting lithium in northern Tibet, salt plains of South America, and Chile as well as lithium at Bolivia's Salar De Uyuni require extensive extraction operations and water in a dry land.

This is quite the sob story until you compare it to the history of the fossil fuel industry. I'm not excusing it, but as a reason to buy gas instead of electric, it's lacking.

This might sound bad, I honestly don't even care about blood coming from people and their questionable mining operations as long as the Earth doesn't cook me or my kin alive. I think we're at a crisis and there will be much more blood in the future. The root of the issue is consumption.

and yet the following is not topic of discussion in rebuttal.

When it comes to mass production of hybrid and electric vehicles, the main problem has been a shortage of batteries. And the main material in growing demand is lithium.  An element found in abundance in South America, where the cheapest extraction method by evaporating salt brines in the solar ponds deploys usage of cheap and toxic PVC; and in lithium-rich regions of Chile where extracting the metal uses two-thirds of the area’s fresh drinking water.

What about how the electricity is produced to charge those vehicles. Or if you say solar panels which I'm sure doesn't provide 100% of the electricity what about the manufacturing of those. People buy electric cars to try and feel good about themselves but fail to realize how much damage they will do when the batteries are time to be replaced. Or how the power is being generated in the first place.

Are we going to ignore the immisions when making these things. Or the fact that Boone is willing to fix ev so any environmental impact saved is lost 1000 times over when someone that needs an 800$ charge port changed is told it's going to cost them 16000$to repair there car and to just buy a new one this is what happens when you break anything on an ev right now and with right to repair in jeopardy even if someone wants to fix them they may not be aloud to or the parts will not be made available.

Climate change is a hoax. I'll take my fossil fuel vehicle any day. You will never stop using fossil fuels. Everything you own is possible because of fossil fuels, even aspirin. I'll also take fuel sourced in the US by grown men to batteries whose materials are mined by child slave labor in countries that hate us. What could possibly go wrong?

Another fool. Just because the emissions do not come out of the tailpipe doesn't mean 400 miles away the power plant isn't spewing out carbon. Your scope is so small and lacking any intelligence.

I'm sorry but this big myth that oil controls politics is bonkers. It is cost that has kept adaptation of electric. As costs went down, so did the ownership in electric increase. Not everyone finds a Prius the right vehicle for them. Can't haul much or tow. Can't carpool with the soccer team either. If your single or have a small family, the Prius is great. Can we get back to facts instead of spreading quantifiable false information that big oil has kept electric at bay? Utter nonsense. That Honda Insight with 2 seats got MPG in the 60s but with only 2 seats. Not many would think a 2 seat automobile is right for them. The first Tesla was a 2 seater as well based in a Lotus sports car.

I always find this argument interesting. We really need to look at the whole package for vehicles. From mining the raw materials, shipping, refining, part creation, assembly, vehicle shipping, lifespan, power source used to charge, and ultimately recycling the vehicle.
The numbers when you take the full lifespan of the vehicle into account, I haven’t seen any numbers showing that EVs produce any less greenhouse gasses.

On top of that, EV companies sell their carbon credits to other companies, which negatively impacts overall carbon production numbers too.

EVs are a scam.

Honestly? The carbon footprint is comparable. Tesla is worse with their lithium batteries, don't even get me started on the environmental impacts of lithium mining. But to produce the electricity to power that bolt, or Tesla, or any other fully electric vehicle, carbon is produced in much higher quantities to create electricity at coal burning plants. Over 60% of American electricity is still powered by carbon-emitting methods. You aren't really helping the environment wirh an electric car, it just makes the buyer unable to personally see the carbon being produced and therefore feels more efficient without doing much. Hybrids are the best blend of carbon-reducing technology on cars in my opinion, at least until we look more into hydrogen powered cars. Toyota and I believe 2 other companies have hydrogen powered cars which don't use gas or electricity. I'm a gas junkie but I still think we could clean up our emissions, for sure. However, electric cars aren't at all where people seem to think they are on emissions. Accoesinf to a study, it takes a Tesla 17 years to outweigh the carbon produced just to make the car. Again, lithium mining is horrible. I forget the name of the study and it very well could be wrong, but something to think about.

No hate in any of this, I just wanted to throw it out there as another opinion, maybe even spark some interest in yet another alternative energy source. Nuclear would be cool but people don't seem to trust it, despite the intense modern safety regulations. Oh well.

Hey dummy, like many other batteries, the lithium-ion cells that power most electric vehicles rely on raw materials — like cobalt, lithium and rare earth elements — that have been linked to grave environmental and human rights concerns. Cobalt has been especially problematic. Making matters worse your crooked racist bumbling prez Biden who no doubt is your hero is Banning coal plants in USA where we just happen to have the best technology to produce Clean Coal.. mean while China is building coal plants every day as we speak so take your head out of your ass and stop getting brainwashed dummy!!!

You paid roughly $1 per kW ($ per mile is irrelevant and varies by car and driving style) which is insane. You got robbed. At home is about $0.11 per kW and the most expensive Tesla Superchargers are about $0.30. There must be something wrong with that charge.

Dan, exactly right. As the first line of the story states, EV charging in public ranges in price from free to expensive. This is a story highlighting the expensive end of the curve, which the story states in the opening paragraph. I'm glad somebody read that far in ;)

Exactly. This is effectively the same as filling up with gas when the meddle moves just off full. Most people don't do that (unless returning a rental car). Repeat the test with a charger from 20 to 80% and then see how it compares.

Correct. I also mostly charge my Model3 at home which averages 12¢ per kwh. But when I charged it outside in Tesla's public charging station couple of days ago, I was was charged 25¢ per kwh. $1 per kwh is too high, there's something wrong. May be they parked it there for a longer period even after charging was complete. So they might have charged penalty/fees for blocking the chaging space.
