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?

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.

As the story details, there was no choice. The DC FC options in the Metro Boston to lakes region corridor are 2. I picked the one that was open. Even that required a detour. The very first line of the story makes your point to ensure readers understand that the prices of charging range from free to very expensive. When you are visiting Southern-Central New Hampshire from Canada, which DC FC do you frequent?

That wasn't actually the first line of your 'story'.
But what you're quoting should be the title of your article.
Instead, you chose to use clickbait to justify a few extra views.
A little pre-planning and I'm sure you could have got away with a little two charger.

This is actually the first sentence.after to he Head line.

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..

What your headline should read is
'if you don't know what your doing, do some research or you'll pay too much to charge your EV."
As you stated, you didn't think about the cost .
I pay a tenth what you did at a level three charger.
For only 34 miles you could have used a level 2 charger for free.
Use the plug share app..

EVGO is transitioning from per min to per KHw
30 states now approve charging by KHw after bipartisan legislation said it should be that way.
Just give the industry time. EV will eventually be cheaper than ICE to ‘fill up’

Looks like someone is sticking it to the wrong man. I would like to see the details of the charging session because the lack of details makes me suspect that the charging session depicted may be out of the norm for price, and may have incured some type of penalty for idle time or something like that. Seeing all the details will allow us to see the process and results through the lens of truth. If you don't supply complete details about the session reported then you may be practicing deception.

Aside from the screenshot of the EVgo receipt, the location of the charger, the miles added, time on the charger, cost incurred, state of charge start and end, and the circumstances of the charging, images of the vehicle at the charger and of the charger, what added details can I provide to help you feel the charging done in the story was real? Other commenters in this string have already validated that their experiences were similar or the same.

I only charge my leaf at home. I have plenty of range for all my trips within a 65 mile radius. A long trip I use my hybrid Volt. No reason to force a square peg into a round circle. Solid state batteries are not here yet. Thus EV is an predominantly still more for local use.

Well said, Marc. I'm glad you used the "Radius" term. For most of my time with test EVs, that is how I think of their operational range. My home charger does the job (well) almost every week I test a new EV. Many PHEV and EREV owners say just what you did here - Plug-in hybrids are the ideal green vehicle solution (today) for those that want long-distance convenience. Cheers

Per minute charging really is a scam most places since most charging stations don't take into account the charging speed of the vehicle. I would be interested in seeing a new version with different EVs once the Tesla network has opened.

I feel like I can take my Model 3 anywhere without an issue because of the network, I'm hoping the opening of the network will help others as well.

Based on Elon's comment though, I don't think it will be wise to charge a slower charging vehicle there, but having the option is always a plus.

Josh (not verified)    December 14, 2021 - 2:59PM

I recently drove over 1800 miles for a road trip in my Chevy Bolt EV. I'm not going to say it was convenient to stop for 45 to 60 minutes to charge. But it was CHEAP. I spent less than $100, total, on charging. That's about 18 miles per dollar spent. An equivalent of 54 mi/gal at $3/gal, which were around most of the gas prices I saw. Not many cars can get that kind of mileage.

Like I said, it wasn't convenient, and I would NEVER do that with my family while traveling. But driving alone, it wasn't bad and it WAS inexpensive.

Brian Simpson (not verified)    December 23, 2021 - 10:03AM

You could have driven 5 miles an hour slower on that leg of trip and it would have cost nothing as you would not need to charge that top twenty percent.
Or at the rate you were charging you could have used a stage two which are free all over the place.

Thanks, Brian. Now I have comments telling me I drive too slowly (and thus get unrealistic fuel economy) and a comment telling me I drive too fast (and thus have poor energy economy) under the same post. Like I mention in the very first sentence of the story, and then a second time in the paragraph in bold titled "Charging For Free," charging ranges from free to expensive. Thank you for your comment.

I live in New York City. First of all there are very few electric car charging ports. The few that there are charge so mich money-4 times what gas costs. Why? Why is electricity so expensive for cars? How will electric cars become desirable when they are so expensive to charge?

Jesse (not verified)    December 23, 2021 - 10:02PM

That's odd... I fully charged my Prius Prime today on a Blink charger at Ikea today while I shopped. It cost me $1.25 to go from 0 to 30 miles of range.
That's about 1/3 the cost of a gallon of gas where I live.
But, I do normally charge at home on my level 2 charger and it doesn't cost that much.
I would suggest this service provider is charging a serious markup.

Doug Duwenhoegger (not verified)    December 23, 2021 - 10:03PM

This is complete BS. You did the one thing that is most expensive and pass it off as a normal thing. How much f'ing money are you getting from big oil? (Post edited for potty talk)

Anyone who knows anything about fast charging will recognize in a second that receiving 9.510 kWh of charge in 29 min 23 seconds is not fast charging. At a minimum I would expect to see 35- kWh of charge. Most EVGO and Electrify America level 3 chargers are rated between 50 and 250 kW. I don’t recall any reference to the time of day or season, but I would suspect that this EV owner had to pay a “critical peak energy charge” passed on by EVGO due to high demand due to high temperatures in the summer.

Truth (not verified)    December 24, 2021 - 4:43PM

The gas price paid is a lie. Also, the entire comparison is garbage because the foundation of the comparison is biased.

A nearly 800hp v8 needs premium gasoline otherwise it will knock. Newer cars retard timing to reduce knock but that lowers efficiency. So either they used low grade gas at lower efficiency (reducing MPG) and lied about the resulting MPG, or they're lying about the price per gallon since $2.9x was "regular" (not premium) pricing at the time. Today, regular in Bedford, NH is $3.0x per gallon. (More than in the article, further throwing a wrench into the gears of their argument.) And, of course, they didn't test with the national average cost of gas. On the West coast, gas is almost DOUBLE the cost.

So if the Bolt and Dodge we're both tested on the same route and the Dodge averaged 24MPG, then I'm calling BS or the whole test was highway miles. The Bolt is already one of the least efficient EVs, which is a fair compassion with virtually any Dodge. However, the Bolt does worst on the highway while gas cars all do better on the highway. Based on the MPG numbers boasted in this article, I can only assume that the entire test was done on highways. That's likely also why they used a Bolt, rather than any other EV, like the most popular ones (Tesla, Leaf, Hyundai, etc).

No matter what, this article is an IQ-lowering bag of trash information .

The entire world doesn't revolve around your failed communist state. Some of us really do pay less than $3 for gas SHOCKER! I know. Some of us drive 100+ Miles a day just for groceries. If you live in California in a city you shouldn't even own a car. Literally everything you need is within 5 miles of you? Where are you driving?

Dave McCord (not verified)    December 26, 2021 - 1:17AM

This kind of moron click bait drives me nuts.

Truth, I live in an apartment, so no home charging. Witch is Way cheaper. I charge at the end of the block at a public charger. I pay about $6 - $7 for @ 100+ miles range. In my old car that would get me @35 mi. On a good month I can save enough to meet@ 1/2 my car payment.

And NO. The earth is not Flat.

Bob (not verified)    December 26, 2021 - 9:41AM

I drive an audi A8L TDI that has almost 500 ft lbs of torque 305hp, and gets 37mpg highway. My cost is less than $0.10 per mile, and I can get around 800 miles a from a tank. I can go from NYC to Chicago without stopping.

Phill Hill (not verified)    December 26, 2021 - 11:01AM

X cents per mile + add at least $22,000 for end of life battery pack replacement. About an additional 7.5 cents per mile.

Tom (not verified)    December 26, 2021 - 11:25AM

Wish I could find gas at $2.90. The lowest price around here is $4.09 at Costco. Average is $4.55. I seen gas the other day over $5 per gal.

For every person that mentions they charge at home, work or a Tesla supercharger, what does that have to do with the topic of the article?

The point of the story is that in many places if you take your non-Tesla on the road you might have no choice but to pay ridiculously high prices for public charging. This is a fact.

Cesar (not verified)    December 26, 2021 - 3:54PM

Where is this? Here in Long Beach CA I can get 43
KWH for $15 dollars in evgo, so the rate shown in this article is not representative of the majority of super chargers.

Hi Cesar. The answer to your question is in the second sentence of the story. You are absolutely right about this not representing the majority of the "super chargers." Superchargers are Tesla high-speed chargers and are not public DCFCs, which is what the story is about. That said, even public DCFcs like those from EVgo are not typically as expensive as the example in our story. Thanks for checking in.
