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.

I love how many of the commenters here simply reinforce the perception that EV owners are crusading snobs, or possibly 4 year olds that want to stamp there feet because they apperantly do not have the ability to understand something before proving their ignorance, and as soon as they perceive an attack on a conviction they hold so dear, they can't help themselves but to defend their holy crusade.
The article headline was not click bait, the author did not have an agenda, the author was not setting up the Bolt to fail the comparison with the Ice vehicle.
The author was very specific in setting up the senario and the reasons for charging when and where he did and for paying the stated amount. If you actually read the entire article as a whole and stop picking and choosing which parts you dont like, it is clear the article was showing that EV owners can and do get gouged and that they must plan carefully and be prepared to pay up when traveling away from home especially in areas with low to zero EV infrastructure..
Getting on here and attacking the author for stating what it CAN COST charging at a public station to over 80% and paying exorbitant fees, and extolling us on the virtues of YOUR vehicle and YOUR electric rates, clearly shows you didn't actually read the article, or worse, could not understand it.

I still like my 2006 VW Jetta TDI. Last time I filled it up 43 mpg on winter diesel for city driving. 168000 miles on it.

There are several things wrong in this article, first is his math does not add up, second a hemi of 700 HP is not going to get the milage he is claiming, 3rd I have found that charging station is like gas stations some low price some high, he intentionally went to a high prices one 4th he is comparing a low end low mile EV to that of a better model this story gives the appearance of a dislike of EV's based on bad information and lack of knowledge

Thanks for the fact-check Sarge. I included an image of the MPG display of the 797 (not 700) hp Dodge Charger I drove on the same route in the story. I think the intro to the story covers your second point. Lack of knowledge? A link to my credentials is at the bottom of the story.

In California we are paying more than 4$ per gallon for gas and my electric car is getting 4.5 miles per kilowatts so it is much cheaper for me drive my electric car than my toyota that gets 25 miles per gallon

Daniel (not verified)    July 17, 2021 - 10:36PM

Really depends where you are. Fast charging is 11$ an hour here in Quebec. Juste made a 600km trip for 6$ on a fast charger

Chris Dotson (not verified)    July 17, 2021 - 11:00PM

I drive a Tesla MX, and it costs me less than $10 to charge to ~80% at a Tesla Supercharger, which gives me about 250 miles of range.
It's the wild west for EV charging. Companies can charge whatever amount they want and EV drivers will pay. Charging stations just aren't as prevalent as gas stations.

As for me, EV gives me anxiety. I wouldn't take my road trip without my Honda Odyssey (3400 miles in two weeks) this year.

Midwest matt (not verified)    July 18, 2021 - 9:39AM

I have a 475 hp SRT. No way in hell you got 24mpg combined in that Dodge. Pure highway, in eco mode...sure.

John Goreham    July 18, 2021 - 11:43AM

In reply to by Midwest matt (not verified)

Midwest, it was indeed pure highway. That is really the only practical way to get from Metro Boston to South-central New Hampshire. 93 North to either 101/114 or 89 North to 202. I didn't use Eco, but I used cruise control set very close to the speed limit because there are staties every 10 miles, and cars with 797 hp painted arrest-me red tend to stick out. Luckily, Stellantis lets use Monticello Motor Park once or twice a year, so we get to flog these cars in their natural habitat. Which sure as shite is not city driving.

Actually Dodge recently unveiled a function that cuts the engine down to 5HP as a theft deterrent. If one punches incorrect pin you get 5hp. I am unsure if you can do eco with the engine cut down to 5hp, but I am pretty sure the MPG would surpass a Hybrid hah

I am glad so many EV driver commented on the on obviously misrepresented data in this "article". There is not 1x way to compare icev costs vs ev costs. As a family of 5 with 2x evs and 1x icev in CA i can tell you I compare the 2 in monthly cost of "fueling" up. Our icev monthly fuel up costs can range from 90 - 150. Our ev fueling monthly costs for 2x evs ranges from 118 - 160. I should also mention we live in apt homes and rely on EVGO specifically as our main source of ev fuel. IMHO EVGO is the most affordable and versatile fast charging provider in my SoCal area. Even when factoring in EVGO charges per min vs per kwh. There is no shortage of other options. Charge point, Blink, Electrify America. The only one that beats EVGO in terms of price are the free chargers (Volta) that should be found in any state with a serious ev push. My .02 worth you decide how valuable it is to you.

That's way I have a Tesla. Changing at home in Florida it would cost me $10 to go 300 miles. On a trip charging at a Supercharger it would be $14. No more gas cars for me. Also maintenance costs are a quarter of a gas car and even less after a 100,000 miles.

Darec McDaniel (not verified)    July 18, 2021 - 10:08AM

Terrible comparison. One of the worst ranges on an electric vehicle used to figure the charging prices with the most expensive charger. Then, compared to a "gas guzzler" to babe it apart more expensive.
Incredibly misleading article.
The actual facts:
It is mostly free to charge in public, with assume places charging a few dollars for the convenience. Most vehicles gain approx. 200 miles for a quick charge to 80%, since average ranges are well over 250 miles for most modern electric vehicles.
Finally, all other maintenance costs are almost negligible in comparison.
But yeah, y'all stick with the "gas guzzlers" because, you know, reasons.

Darec, we got to your point about EV charging being free in many cases before the end of the first sentence. We dedicated an entire paragraph to your point about the 80% charge limit. We have gobs of content here about maintenance costs of EVs vs. PHEVs vs. Hybrids vs. conventional ICE vehicles. We are often surprised when the PHEVs top the BEVs, but you know that already.

Mightyyoda (not verified)    July 18, 2021 - 1:26PM

At home is around .11 kWh so about 400 miles for $10 or about 100mpg @ $2.50 a gallon. Electrify America charger we usually use on road trips is about 62 mpg equivalent. Don't remember exact rates since usually only focused on topping off while getting food, but it is about $5 for 125 miles.

Bob (not verified)    July 18, 2021 - 1:37PM

Superchargers, plain and simple. Faster, cheaper and way more available. There are cars, EVs and Teslas. I wouldn't buy an EV until the charging network matched Tesla.

I took an overnight trip the morning after forgetting to plug in my Model 3... No problem, just route to a supercharger.

Bob (not verified)    July 18, 2021 - 2:40PM

Very bad sensationalist journalism. I assume sponsored by the oil industry. No one acts like this and pays this much for so little in the real world. Shameful article.

Greg Schoen (not verified)    July 18, 2021 - 3:48PM

Just a quick thought. Those of us that drive motor fuel vehicles , I drive a Chevy PU and a 21 year old Vette. , we pay tax on the State snd Federal levels through the fuel tax. I would like to hear from EV owners on how they should pay for the use the Highways and Avenues of the United States. Thanks for reading.

Bill (not verified)    July 18, 2021 - 5:33PM

Someone made a mistake somewhere. No 795 HP vehicle would get over 24mpg, highway or combined!

Jim (not verified)    July 18, 2021 - 6:41PM

I charge my 2013 Leaf off the spare welder outlet at work. At home I get $40 in charging credits from the power company. The rest of the time I use one of the dozens of free level 2 chargers around the Salt Lake Valley. For longer trips I drive an older Subaru wagon. When it eventually gives up the ghost I'll be replacing it with a long range electric. Once you go electric it's difficult to go back to gas.

Field Tech (not verified)    July 18, 2021 - 7:56PM

Ummm…this article must be written from a gasoline enthusiast’s perspective. The fact is, there are several different factors that could affect the cost of charging, I could name them off, but I really just want to get to the point…this is completely false. I drive the same car for my job, and charge on the same fast chargers as in the pictures, multiple times a day. I pay about $12 to fill it up to 80% from 5-10% which normally takes about an hour of charging. That gives me approximately 140 added miles of charge, and that’s with the A/C running. I have no idea where they got these figures.

Brian Simpson (not verified)    July 18, 2021 - 8:04PM

This article is apples to oranges.
You never use fast charger to top up.
The battery will not take it.
You could have done it at any stage two charger probably for free.
If you were charging that same battery at 10 percent you would have recieved three times the distance. And it would have cost you 10 cents a mile.
I charge my car at home on a stage two charger.
I have a 30 klw battery costs 4 dollars to charge.
I go 130 miles on that charge.
That is 3.5 ish cents a mile.
I hope this adds a reality check on this story.

Ronald C Reed (not verified)    July 18, 2021 - 8:52PM

Something is wrong somewhere, one mile per minute? If that vehicle only traveled 34 miles on 9.5 kilowatts there's a major issue.
I think either your math is off or there's so e outright dishonesty here. $10 for 1/2 charge may be about right but my friend can travel a couple hours on a half hour change in his Tesla and not babying it either.

Our 2019 Nissan Leaf Plus EV averages 270 miles on a full charge. More battery capacity is so worth it. Nissan dealers provide free DCFC. We drive from Brewster to Framingham MA using heat in winter and AC in summer about once ir twice a month. Stop for about an hour at Milford Nissan to recharge to 85-90% on return trip. Mostly recharge in our garage and solar panels on our house fulfills all electrical requirements. Planning your round trips ahead is essential to ensure charging availability and cost.
