How much does your EV costs to charge?

Are you saying that you charge your car in 4hours? From zero to full?
4 hours charging a night is enough for 30k miles a year. gangzoom said:
Isn't the price cap potential going to hit 30-40p per kWh? So pretty much 10p per mile for fuel costs on any EV, thats before government starts taxing electricity like petrol. Its not inconceivable EVs will cost more to run than petrol cars, which ultimately is what governments need to push for, less car usage overall, if anyone actually believes in climate change.
The 5p per kWh prices are unsustainable if electricity costs don't come down.
I see Japan is now building coal power stations as they remain the cheapest way to generate electricity. If we want to have cheap electricity surely we have the answer?
Personally when it really come down to it, I care more about the cost to me for energy than how its generated.
It's going to be cheaper to run your house / EV off a diesel generator soon!The 5p per kWh prices are unsustainable if electricity costs don't come down.

There's a lot of BS here about how cheap EVs are to charge. If somebody signs up to an electricity supply contract now, they can't get a unit for 5p. B
oh look 5p/KWhhttps://octopus.energy/go/
and its not economy 7, the day rate is not higher
the problem you do have that because of all gas shenanigans the day rate is very high for all new contracts

I heard a rumour that one guy at work got caught dangling the granny lead out the window to charge his EV. Think the company sacked him and were trying to prosecute for fraud / theft.
The company probably wondered why their electricity bill went up. It wouldnt surprise me if they were on a rubbish tariff
Sounds like someone I used to work with. Would bring in all his personal stuff so he could charge it at work - Laptop, iPad, GoPro etc. He even used to charge a couple of power banks to use at weekends.The company probably wondered why their electricity bill went up.

I once jokingly asked him when he was going to bring in a cordless drill and he said that he just borrows his neighbours power tools.
He used to ride a moped to work, but it wouldn’t surprise me if he tried something similar if he’d switched to an EV.

I feel I need to clarify my earlier comment regarding the 5p per unit cost. What I meant was the gross cost of these deals is higher, as you pay more standing charge and/or daytime rate than normal (whatever that is in these odd times).
Nope. On Octopus GO my daytime rate is the same as the standard contract, but I pay 5p/day more on the standing charge. So I don't even need to charge a kWh per day during the 5p window for it to make sense.48k said:
It's available but when you join Octopus Go you don't get 5p/kWh straight away. They put you on the standard variable rate, whilst they "join the dots behind the scenes" - whatever that means which takes a minimum of 14 days. You also must have a SMETS2 smart meter - if you don't have one you stay on the standard rate until a SMETS2 smart meter is fitted (what the lead time is on that I don't know), and then after your smart meter is fitted it takes an additional 14 days to switch from the standard rate to Octopus go.
I am on Octopus Go Faster, and have a SMETS1 smart meter.JD said:

This is going to be a serious problem for EV uptake, we are potentially looking at a 225% increase since the start of the madness when the next price lock is set in April at potentially 35-40p/KWh, thats around 12p/mile in electrickery which i have no doubt a good diesel could match Unless you can get cheap off peak deals, if they still exist
Wonder what the RoI would be on a powerwall filling it up at night for 5p/ and using it during the day to avoid the 35p/ ??

Loads of ways you could do it, cheap over night tariff, finding somewhere that has free chargers (this is getting less and less)
Someone always has to pay for the electric it's never free.
To work out the cost it really is quite simple, electric cost 19p (prices vary) a Kw, so to charge a Polestar for example with a 78kWh battery would cost around £14.82 which would get you around 250 miles.
It is not really ideal if you have to stay with your car and is away from. (Re free chargers)Someone always has to pay for the electric it's never free.

I have been contemplating with the idea of buying an EV, but this seems not so cheap after all. As others mentioned going to wait for another 10 years for it to improve and hopefully make more sense.
Most people don't do more than 100 miles in one day as that's 26k per annum (based on Monday - Friday)
A diesel car doing 50mpg would cost me £12.50 instead of £1.50 so the difference is massive and a Polestar 2 isn't even that efficient compared to some EVs.

If I'd managed to lock in one of the cheap tariffs would have been more like £5 v £50. 
Dont beat yourself up. Pretty much everyone offering super cheap deals have now gone bust and customers not getting many options of where to move to.I was chuffed with price and thought to save money... There was a fee for cancellation. I wonder if I could charge them for failing to provide...

Maths seems pretty straight forward. Charging at 5p to avoid paying 35p saves you 30p per KWh.
Let’s call it 25p with a few inefficiencies.
So, how many KWh do you consume at non cheap rates per <time>. Multiply that by 0.25, that’s the saving.
Work out how much a power wall will cost to install.
Time to break even drops out.

Forget EVs, its going to hammer everyones electricity bill. I was paying 12p/kWh peak and 6p/kWh E7 rates only 18 months or so ago.I see gas prices jumped up nearly 10% again yesterday and winter has barely started. 40p kWh before any kind of motoring tax is added on, MPs are clearly living in fantasy land if they think people are going to be happy about paying that kind of price for electricity.
Surely its time the government considers how to manage energy costs for the mass public. Who really cares about been 'green' if electricity bills for everyone is going to triple/quadruple soon!!
We have a readily accessible source of heat and fuel in coal, why aren't we using it like Japan, Austria, India, China, Germany, USA, so pretty much everyone else.

Currently have a ICE car as I live in a flat with no way of sticking a cable out to it.
But going to be moving next year, A lovely new build our forever home and I'm going to make sure I do it right as we all know electric cars are the future even if it's the wife's car to start with.
I'm getting the builder to put in 3 phase electricity as that means if I pick the right EV I could charge at 22Kwph So thats 5 hours at night = 110Kw into a battery at 5p per KW = £5.50 In the real world you wouldn't be charging 0% to 100% every night so 110KW would maybe even be too much each night but its better to over spec as I might have two EVs in the future.
The next is solar, If you get 3 phase you can go over the 6Kw limit which 6kw is great in the summer but not great for the winter, I'm following some builds at the moment which I'm thinking of getting once we're in and they don't import anything for 3 to 4 months a year. With very little import the other time, Hot water and car full most of the time.
Electricity prices currently are skyrocketing, All these great ideas, Closing coal power stations, Gas skyrocketing, Nucular costing 23 billion to replace. Or I can try to produce and store as much as I can while everyone else says it's going to come down, Battery storage and wind is the answer yet the tech is there and the grid companies are not building it.... Because it would be easier instead of building a gigabattery why not put one in each house. Maybe EVs can help in this aspect.

Just a note, I’m pretty sure you won’t be able to charge at 22kw/h. It’s 11x2. So you can charge 2 cars at 11kw/h. Any more than 11kwh and the plug on the car end of the charger is different.

Happy to be corrected but that’s how ours works (we have 3 phase). If it makes a difference, 11kw is plenty fast enough so you don’t need to worry.
Also, one of the most inefficient uses of PV solar produced electricity is making hot water. Better to use it for charging the car and heat pump.
