How Much Does It Cost to Charge an Electric Vehicle? (A comparison at home and on the road, with gasoline)::Few people know what a kilowatt-hour costs them, so they don’t realize how cheap EV home charging is versus gasoline. On the road, it's more complicated.

$0.058 / kWh at home for me.

About $0.115 at my friend's house.

About $0.25 at some public chargers.

Those are amazing prices.

In Germany I pay:

-0.33$ at home and work

-0.72$ - 0.88$ on public chargers

Gas is currently about 7.68$ per gallon. ._.

Right?!? Wildly jealous of those low electricity prices. I'm also in the EU and paying 46.6c (euro) / around 50c US at home.

Yeah, the quoted $40 fillup is in Hawaii where everything is expensive.

Some UK prices for comparison:

At home within the EV charging window with Octopus I pay 9p a kwh, outside that window its just over 29p, so I never charge outside the window. I also run my dishwasher, washing machine and anything else I can during that window, typically excluding my EV charging (we are a 3 EV household as both my kids have EVs), we have about a quarter of our electric usage during the cheap window.

Typical cost outside the home for a charger up to 22kw is about 45p a kwh, rising to 75p a kw for ultra rapid pushing out a couple of hundred kws. Its pretty normal in the UK to pay more for a faster charger.

Some places still have free charging but these are drying up, and typically they are limited to a couple of hours of charging at 3 to 7kw.

Petrol is 155.5p a liter, or about £7.06 a (UK) gallon. A modern ICE than is a similar size to my EV should be getting around 50mpg, so 14.12p per mile. 70mpg is possible out of a modern self charging hybrid, this is about 10p a mile. Plug in hybrids potentially offer the same battery power only for 100% of the journey that a full EV offers in the UK for the majority of journeys, as the UK average distance is about 8.5 miles.

Worth pointing out that petrol on a motorway service station (where you will mostly be charging your EV on a long journey) jumps from 155.5p to 177.86p. This increases the cost per mile for the 50mpg example to 16.14p.

My EV gets 4.5 miles per kwh in the summer so about 2p a mile, when its properly cold in the winter than drops to about 3.5 miles per kwh or 2.57p per mile. Assuming an ultra rapid charger at 75p a kwh, cost rises to 16.67p for summer, and 21.42p for winter. Obviously you only charge what you actually need to complete your journey at that price, not fill it up to 100%.

Assuming an equal cost to own and run (which is not the same as purchase price) EVs are significantly cheaper in the UK if you charge at home. If you cannot charge at home then I would look into a provider like Shell installing an on street charger in a lamppost or not bothering at this point if you are motivated by cost.

That's really useful information. Thanks for taking the time.

19 cents/kwh at home, and that includes all fees and taxes. The most expensive charge I did was at a Petro Canada, which was 53 cents a minute. I was just topping up so the 20 minutes I was there came to a whopping 91 cents/kwh. There's a lot of free fast chargers where I am too.

I appreciate the plain English for the mixed bag it is for apartment dwellers.

Can we have electricity? No, we have electricity at home!

[–] cbarrick 5 points 1 year ago (1 children)

This summer, at Electrify America in Erie PA, I recently paid $0.35 / kWh. And at Electrify Canada in Hamilton ON, I paid $0.57 CAD / min, which is $0.23 CAD / kWh at 150 kW.

This is roughly on par with the cost of gasoline, per mile. I assume the margins are pretty thick for Electrify, because household electricity costs less than a third of that.

For example, say it costs $0.35 / kWh. At 3.5 miles / kWh, that's $0.10 / mile.

For comparison, say gas costs $3.50 / gallon. At 30 miles / gallon, that's $0.12 / mile.

I got it how to charge at home or ok the road, but how with gasoline ?

[–] FauxPseudo 14 points 1 year ago (1 children)

Fill a generator with gasoline. Plug the car into the generator.

A completely typical situation, and not at all used to try to derail change.
