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.

Typical NON-Tesla story. Tesla Superchargers do NOT charge these prices at all. I charge my Tesla for free with excess power from my office solar system This story sounds like a gas company job.

You are exactly right, Beau. This is one of those stories that is not entirely about the specific brand you drive. Insulting, right? Thanks for reminding everyone that Tesla's private charging network is awesome, and how great it is to own your own subsidized-solar-capable home.

EV Go is very expensive. I always avoid it. I feel bad for EV owners don't have access home charging solutions and must use paid public stations. I charge my Bolt at home; it costs only 20 cents per kWh.

Brian Sinclair (not verified)    January 9, 2022 - 10:45PM

This story makes no sense to me. I charged my Model 3 LR Tesla today and added 50kwh bring my battery from about 30% to 85% and it only cost me $18.50. That is more than I would have spent on gas (I live in NJ where gas is about $3.35 a gallon). I rarely charge on the road as I have a home charger, but this story makes no sense.

We'll try to explain it better for you Brian. The first step is to calculate your cost per mile for energy. Bringing a Model 3 from about 30 to about 85% SOC means you added about 150 miles of range. If you add 150 miles and pay $18.50 for those added miles your cost per mile is 12.3 cents per mile. That's 20% more expensive than a gas car of equivalent size to the Model 3 would cost per mile if it had an MPG rating of 33.5 MPG and gas cost $3.35 per gallon (ten cents per mile). You are paying MORE per mile than the average Camry or Accord owner does to move your car around the roads you drive in New Jersey. You are paying twice as much for energy than a Camry Hybrid (50 MPG) owner who would have a cost per mile of 6.7 cents per mile. Your cost for charging is not the same as the example in the story. The example in the story includes a higher cost for energy at the EVgo DCFC station we used, plus some other factors. Thanks for commenting.

This is absolutely a “hit” article. The most I’ve every been charged for public charging is .42 cents per kwh. I’ve had an EV for almost a year and 13,000 miles on it. I’ve travelled extensively.

Another plus for an EV i’d the lack of maintenance. I have not spent one dime on maintenance - no oil charges, no filter changes etc.

I would never buy another gasoline vehicle.

Spotting Dimes (not verified)    January 10, 2022 - 11:44AM

Meh... The problem with an article like this is that while technically true, it distorts the actual EV ownership experience. For non EV drivers the takeaway is that EVs cost 3X as much to run, but of course, the reality is anything but. I'll concede that I have run into this and have whined about how expensive charging can be, and especially when you are trying to top up because you are afraid that you won't be able to find another charger. But then I remind myself I willingly, spent the best part of $30 / week for gas, every week. And if you are charging at home this is almost never an issue (can't remember the last time I went to a public charger but probably not in a year). No question the infrastructure is not where it needs to be (maybe, with the exception of Tesla) for widespread adoption among those that cannot charge at home (some would argue different, but for me I would not tolerate the inconvenience of having to do all my charging at public chargers). So, in the short term if I have to pay a premium for public charging so that I can extend the utility of my vehicle, then it's a tradeoff I can tolerate. But the infrastructure is only gonna get better which should negate the need for last 10% charging as well as driving down the cost through competition.

Technically true is true, No? We threw that chart into the story about how rarely EV owners actually use DCFCs because we completely agree with many of the points you added here. Tesla's private network of charges is very good here in New England. They only had service centers in half of the N.E. states when we checked last, but private chargers they have in abundance.

If you own an EV you know EVgo is a ripoff so yeah don't unless it's an emergency. I charge at home it's 20 cents per KW. And EVs regenerate a small amount of energy from braking. Also my VW has 3 years of free electrify America charging

Justin (not verified)    January 10, 2022 - 4:48PM

The charger charges by the minute you used... And you went above 80% which slows it to a trickle. Extending your time by about 100%. Real cost was probably less than $4. Lastly it's not etiquette to go to 80%... It's rapid charging to 100% eventually damages the battery... Please read.

I own a 2019 Nissan Leaf SV, and it performs very close to what the manufacturer said. It goes 3.333 miles per kWh or it uses 300 watts per mile. To answer your question, I used an EVGo charger one time because my battery was “low” and it cost me $11.18 to go from 6% to 85% or from 8 miles left to 114 miles. EVGo charged me 43 cents per kWh or 10.5 cents per mile. When I charge at home, it is FREE because I have solar and we overproduce every month. Otherwise it would cost us 27 cents per kWh to charge at home. And we live in California so our electricity costs are at least twice the national average.

Luke (not verified)    January 19, 2022 - 9:11PM

I pay $10 for a full 240 mile charge on my Tesla. You know, on road trips. Otherwise I charge for $600 a year at home for $10,000 miles, which is vastly, vastly superior to any ICE auto. In other words, I'm saving about $3K/yr, bringing the lifetime cost of my Tesla to under $30K. It's the cheapest luxury car there is.

Ian Markey (not verified)    January 20, 2022 - 2:33AM

This probably isn't allowed here but I will say it anyway. I don't like 100%Ev. I would maybe get a hybrid half gas half electric. But I can't be sold on 100% battery. I can't be limited. I like what I have now I can hop in my 16 ford focus and go when I want for as long as I want. I deeply resent people trying to force us all into these oversized golf carts and eliminate fossil fuels. To each their own if people want to do that lifestyle have at it. I don't think it's right to force that lifestyle on me. Which is unfortunately what democrats want to do. They can never stay on their side of the fence and leave their neighbors alone. Gotta be all up in my business telling me how to live me life. Just leave me alone go drive ur golf carts and be happy and let me be happy with my fossil fuel cars.

Shell station in Tewksbury Mass on Rt 38. Note the time stamp of the story. Gas Buddy is a very helpful tool. In my area of Mass. today there are a number of stations with Regular under $2.99. Right now, even with much higher gas prices than when the story was written the best Premium price is $3.10 at BJs in Leominster. Are you completely convinced now? https://www.gasbuddy.com/gasprices/massachusetts

Don Rutherford (not verified)    January 20, 2022 - 9:32AM

The only way I would buy one is if the car could recharge itself while driving. The manufacturers could make a self charging device ( alternator, generator) powered off any one or pair of wheels

Every hybrid, plug-in hybrid, and battery-electric vehicle has that ability, Don. Energy regeneration during deceleration is one key reason why they all have such great efficiency. Plug-in hybrids like the RAV4 Prime can even charge their traction battery using the gas engine.

I charged my 2021 Model Y LR at a Tesla SC last week. At arrival I was at 80% Soc. I was stuck in traffic and was rerouted to a road that was in front of the chargers, so I stopped. Normally, I would not charge at this Soc. I was there for 25mins and it put 17% into a 75Kwh battery. Sorry, not sure how many miles that was but the cost was $2.54. I know it was more than 34 that you got in your Bolt?

Thanks for the comment, Rick. Tesla's private high-speed charging network is really outstanding for the folks who have $60K or more to pay for a new crossover. This story is about public chargers. I did the math, you added about 53 miles in 25 minutes. Quite quick given that you did the dastardly deed of charging above 80% away from home. That's a rate of about 5 cents per mile for energy, also quite good. Not as good as free, which is what Mr. Musk originally told the world Supercharging would be. But still way below the market rate.

I have owned a Fiat 500e for five years now. It is my daily driver, and was the first of the Fiat 500 EV's, so it's range is limited by comparison to newer EV's. I regularly charge at home and at public chargers. Where I live, pay chargers are provided by Charge Point, and Blink. Even though I can't utilize the fastest charge options, I have never paid more then 6.00 to fully charge, and on average I pay about 3.00 to charge for about 30 min. which is more then enough for my return trip home, which is about 25 miles.I have only had to service my car twice, both times due to the 12 volt battery, which can cause problems in ICE cars also. I never have to worry about oil changes, fuel filters, spark plugs, none of the costly maintenance that comes with ICE vehicles. The regenerative braking system has also meant I have not had to service my breaks, not even once yet in five years, and I have them checked regularly. I charge at home overnight when the electricity rates are lowest, and it costs less then 15.00 a month, yes a month, to charge my car at home. So I charge an average of 3 times a week at public chargers, and 3-4 nights a week at home, meaning that I have not paid more then 30.00 a month for charging as long as I've owned the car. Add fuel saving to maintenance savings, and it's several hundred dollars a year less then when I owned an ICE vehicle. I will never go back to an ICE car. There are definitely overpriced public charges, just don't use them unless it's an emergency.

Thanks for your comment, Susan. Particularly for your conclusion that the premise of the story is validated based on your real-world EV ownership experience ("there are definitely overpriced public chargers"). I did some quick math and found your cost per mile for energy when charging publically ($3 for 25 miles) is about 12 cents per mile. Nowhere near the extreme example in the story, but still roughly double the cost for energy a Prius owner pays. And about the same as I pay for my all-wheel drive gas-powered crossover.

So you have to charge 30 minutes to drive 25 miles home? I have 212,000 miles on my ICE SUV that is 18yo. I still have the original fuel filter and my car battery lasts 5yrs. I just drove 400 miles in 5.5 hours and it was 10 degrees. Stopped for 5 minutes to refill. There are numerous gas stations every 5-10 along the Interstate. Had the heat, rear defrost, headlights and radio on while I recharged my phone in the lighter. I get 4-5 years per brake job too. Let me know how those batteries are in 10+ years of daily driving. When you replace your batteries, all your maintenance savings will be eliminated. My ICE oil changes in every car I've ever owned in my lifetime will be less than your battery replacement cost. I can replace my entire ICE engine for less than the cost of your battery pack replacement. Plus ICE vehicles cost less than EV.

I did say "more then enough to get home, I always charge a bit more then I need. My car is 10 years old, I bought it used. My batteries are still functioning perfectly, except for the 12 volt battery I mentioned, which can be an issue for ICE cars too. Almost all EV's can now utilize faster charging options, if mine had that option, I would only have to charge about 5 min. to get home.

Thomas Beshaw (not verified)    January 26, 2022 - 1:13PM

I have to agree with the article. Every state has regulations that govern gas stations making sure they don't rip off customers. There is zero regulation of charging networks. So yes they charge whatever they want. Charging at home yes is awesome super cheap. But what about people who want to own an EV but only have on street parking like millions in cities? They will be forced to use public charging. Sure some hotels offer free charging. But I was burned a few times even by that. Some charge you "parking" fees once your car is charged. So unless you unplug as soon as its charged up boom you get hit with fees 10 or 20 times even more than the charging fee. I got a 30$ fee once for being plugged in 2 hours more than it took to charge up my car. And these fees are not always advertized beforehand. As either the sign has fallen off or vandalized etc.
My brothers wife wanted a tesla desperately. They live in philly with only on street parking at their house. Once they realized how difficult it would end up being to actually drive 7 miles in city traffic to the nearest charger(not even a supercharger). And the numerous other hurdles they ended up with a much more sensible(for their situation) hybrid.
Personally I traded for an I8 (plug in hybrid) for my model S after only 6 months. Plug the i8 in overnight the 30 miles is more than I need for 99% of my errands I run. Plus on trips with the gf, after getting it tuned 40-44mpg highway at 80+ mph. To get any decent range on the S you had to keep it at 70 max. Even then we preferred taking our diesel x3 on trips instead of the S especially out to the western states. More comfortable, 650 miles between fuel stops and it loves to pur along at 90+ and still average 33mpg.
Why I traded in the S. Number one was interior fit and finish. B Pilar trim falling off, roof liner sag they did replace the roof+trim completely but took 3 months of nag and then still had the one b pillar trim would come off if you hit a bump just right. They really only put in the missing clips from factory not actually replacing it. Even though it had become dirty/scuffed from falling off so much. Loved the S performance. But driving it sporty meant horrid range. I'm waiting a few years now till pure EV is more mature. Then maybe I'll try again. Once EV's with 200-300 miles range that charge in 10 min become the standard you won't hear complaints from most then it will just go back to how people used to shop for a car. Their needs/budget, plus personal style, and then efficiency, sportiness.

Seriously though legislation is needed to regulate ev charging in general to make it as standard as gas or diesel. Then you won't see articles like this and ev will become much more consumer friendly.

Cris (not verified)    January 26, 2022 - 11:11PM

In TX, price is usually $0.03 to $0.07 per minute @ 150kwh fast charger. My Cost averages around 4 dollars to add 200 miles of range.

I would suggest using a different charging station if you're spending that much money.
