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.

The only thing this article managed to point out is that the method of charging for time at a charging station is criminal and it should be based on energy onboarded to the EV the same way volume is used for ICE vehicles.

All the other geriatrics arguing that EVs are pointless are just showing they were C- students who barely got through highschool and never learned basic tenants of critical reading. Lol y'all are embarrassing to the human species.

The automobile landscape is changing, find a way to stay relevant but also still appreciate the classic ICE cars and trucks that are fun to drive.

I found out the hard way that EVGO fast chargers are almost triple what Electrify America charges. Also many places put in ChargePoint which are not fast chargers...takes about 5 hours to get 80%. The infrastructure is not there for me to travel great distances which really is too bad. I rent so no home chargers are available.

John R Abernathy (not verified)    February 14, 2022 - 3:10PM

I think EVGO has a significant flat fee to start the charger. (Assuming their chargers are working-a big if...)

Try to plan out your route and look at your options. (I like Electrify America and Charge Point). Fast chargers with fees are always more expensive than the other options..

First of all that screenshot of the charges is horsesh!t. Show me the credit card bill. EvGo f*cks this up often. Second in this scenario with power consumed from this charger it would have been $3.93 on peek time if you're a member of EvGo or $6.92 if you're if you're not a member. On early bird charging it would have been $2.84 as a member or $5.84 as a non-member. I don't know how they were driving before that charge and what the ambient temp was but my car would get about 44 miles added for the same kilowatts of power delivered. So $2.84 for 44 miles is still WAY cheaper than any gas car I've owned especially now where gas is $4.89 a gallon here in California. $2.84 wouldn't even take my new 2021 4cly truck 20 miles and it gets 22mpg on the highway. This article is all hyperbole...period.

This is the most disingenuous BS I've seen in a while.

EV chargers pricing is per minute. The charging slows down once you're past 80% battery. So of course it's gonna be "more expensive" once you're past 80%. Of course the article doesn't show how you can get +170 miles in 1 hour or less, as long as you're charging below 80%.

It's ok to be biased, but don't lie about it.

Lonnie, paragraph 4 says exactly what you just said. We point out two reasons why charging above 80% in public is a mistake. Not just the one you list. There is also a link inserted at the beginning of the story, sentence 3, that brings the reader to a full story titled "Big Mistakes To Avoid When Charging an EV In Public." It dives deep on the topic of charging profiles.

Jeremy (not verified)    February 15, 2022 - 8:40AM

Just a junk POS article with an author who has a clear hatred for EVs. Cherry picked data for the worst possible scenario for EV charging and then used the highway mileage (downhill?) for the ICE. You know your product is superior when the haters have to play with the numbers in attempt to prove their point.

Hi Jeremy. Thanks for your comment. My credentials are listed at the bottom of the story. I've been involved with EVs since 1990. I've designed and built an EV battery cooling system. To date, I've published over 5,000 EV-related stories in dozens of publications. The car in my driveway right now on my home charger is an Ioniq 5, the review of which, posted here at TN, confirms that the hype over this great car is all justified. Tell us about your background related to EVs.

Meanwhile my buddy stripped his Tesla and sold the parts. The replacement battery was going to cost $24,000 plus labor. It has less than 150,000 miles and no warranty. It's now junk. Meanwhile my Chevy van has 580,000 miles with no issues costing over $50. And I paid $4200 for it. You aren't very intelligent are you? You'd be better off financially owning an ice vehicle getting 8 mpg when you figure in the battery life and replacement costs, outrageous purchase price and extra registration costs..

Mason Dalmau (not verified)    February 15, 2022 - 9:44AM

In California, gas is almost $5/gal... $4.87 when I filled up a couple weeks ago. That really changes the ratio right there, and gets them alot closer to being the same. Unfortunately, I think that the public charging system is in its infancy and is not as streamlined and efficient about lowering costs compared to the gasoline infrastructure that we have been using for over a century. Given time, I think the ratios will shift, especially if gas prices continue to rise so drastically. Also, as batteries become more advanced, or the need to charge away from home will drop, changing the public charging stations into something akin to emergency top-ups or extreme long distance necessities only.

11 people in the survey said “I’m never in DC…”
You would think they’re too stupid to afford an electric car.
Go figure. They probably all vote too.

I drive a 2020 Kia Niro EV in NH and during the summer consistently get 295-300 miles range. In the winter with battery conditioner on i can go down to 200 miles range but normally average 240. I use Electrify America fast charger about once a month to add 210 miles of range for $6 to my car. About 3 cents per mile. I simply cannot fathom any ICE car coming close to that number. I went from $600 a month to $175 a month and still drive the same miles. Would never go back. I do not have a discounted subscription service to the charger or with Electrify America. This is just a registered account with no monthly fee at all.

Thanks for your comment, RS. I love the Niro BEV. It is one of my favorite EVs overall and hard to top at its price point. That is a great rate for energy per mile. Where is that E.E. DCFC located in NH? I'll try to swing by and use it if I am in that area. And this time, I promise not to start charging above 80% SOC!

Bhagavathy Pillai (not verified)    February 15, 2022 - 11:18AM

Elon Musk sold a snake oil, his Tesla just need $8.88 to fill, after he hidden the 68 hours Level 1 charge at 128V Charger at home. This is the true figure of EV Charging Costs. So, EV for Global Warming is just a hype and deception. In actual, 60% of Electricity in Grid is from Fossil Fuel and all the charging & discharging, transmission, leakage losses and the 3 times the cost of even Gas Gusslering Car price, EV is not environment friendly at all. The maximum Environment friendly car is the Prius kind of HYBRID Cars. Anything above is just pure disaster for environment and disaster to your pocket too.

It hasn't become feasible to have an electric car unless you own a home and get a level 2 charger installed.

We have a Bolt and charge at home almost exclusively. We have solar panels on the house that supplies our electricity needs completely, so we don't ever pay for charging the car. That way, if we do go on a trip and have to pay more for charging it really doesn't matter because overall we have paid a lot less.

Hopefully this changes soon. Apartments and condos should have their own charging stations available and just charge the renter or owner normal electricity fees.

Why these EV chargers while on the go charge so much is beyond me. I think part of the problem is that petrol companies like BP and others own many of the charging companies now and they are price gouging.

Whether there intentions are to deter people from buying electric or they are just trying to capitalize on the fact people don't have many charging options I don't know, but it's pretty lame of them to do so if you ask me.

I have an EV and no charger at home and it is still massively cheaper to drive it than it was to drive my Yaris.

The Leaf needs to be charged daily and the Yaris gets 32mpg.

It is still cheaper to drive the Leaf with it's 60 mile range than it is to driv the Yaris at all

MC (not verified)    February 15, 2022 - 2:08PM

No way in hell the 797hp Hellcat Redeye gets even remotely close to 24 MPG combined. In fact it's EPA rated at an unholy 15. And it devours premium gas. I don't know what kind of demonic black magic the author conjured to get 24.

Also you're damned lucky for cheap gas. Here in WA it's 3.99 just for regular.

Hi MC. Every Dodge Challenger earns an EPA-estimated rating of over 20 MPG highway. The Hellcat with the Auto trans earns an EPA Estimate of 22 MPG Highway. Set the cruise control on Rt. 93 North at speeds that won't get you ticketed and you get 24 MPG as the story image shows. Premium gas in Mass. cost exactly what the story shows when the test occurred back in the early summer of 2021. This was answered earlier in the thread. www.fueleconomy.gov.

James C Reynolds (not verified)    February 15, 2022 - 9:00PM

The testing is completely falsified. They put Regular gas in the Hellcat. The Hellcat requires by the factory premium only, which is over $4.00 most places. Therefore the test is false.

Hi James, check the story's by-line date and then do any research you like to prove that I wasn't buying premium gas in Tewksbury Mass at the price shown in the story at that time. I usually go to Shell, but sometimes Haftners decides to beat those prices.

Scott (not verified)    February 16, 2022 - 2:57AM

This is an egregious "sabotage the economics" attempt to make reality stand on its head.
At higher states of charge, you AVOID DC fast charging. You don't drive out of your way to find them! That's like taking a prius on a quest to fill it up with race gas, after you've filled up the back of the car with 800 lbs of bricks to drive up mountain roads... for a fuel economy article.

EVgo's website tells you not to do what you engineered here. You could charge at some random L2 charger wherever you make the math work out. 3-4KW in the same half hour would cost a buck.

Mike (not verified)    February 16, 2022 - 8:51AM

Things to consider, the charging station requires an initial investment by the company for the hardware. Then there is rent for the location and last the cost of the electricity. Also maintenance for the equipment Nobody in this world is going to invest in something without a potential return. They are providing a service and supply and demand control prices. Things will eventually level out as soon as electric cars become mainstream. In the meantime, its the cost of adoptimg new technology for a "greener tomorrow"

Tim (not verified)    February 16, 2022 - 12:42PM

That price was crazy…I use EVGo on occasion but pay nowhere near that price, I do have a home charger, here in California everything is expensive, so I pay .30 cents per Kwh…but nowhere near the $ 4.60 a gallon for regular gas…most the time I use an L2 charger in town (2 miles from my home) where the town highly subsidizes…$03 cents per Kwh, last night I paid $1.38 for 150 miles.
The benefits highly out way the negatives.

David F (not verified)    February 16, 2022 - 12:47PM

The key word that this entire article is built upon is "CAN" It only costs me $16 to do a full recharge at a Tesla Supercharger. Unless you're filling up your gas guzzler for $5, this is moot journalism at best. I'm guessing the next article will talk about how people who go outside CAN be hit by falling meteorites?

plasticarmyman (not verified)    February 16, 2022 - 3:10PM

This is completely inaccurate.

There is a one time fee applied for charging and then it charges by time or energy used.

The math doesn't work like this at all.

Please do your research before listening to uninformed articles like this one.
