How much does your EV costs to charge?

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.

Off peak power is 5p/KWh
Edit; and somebody else pays for mine some of the time.
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. Edit; and somebody else pays for mine some of the time.
The company probably wondered why their electricity bill went up. It wouldnt surprise me if they were on a rubbish tariff

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.

Pretty much as the topic.
I have seen folk claim thant they can charge their car for £1??? Is this true and how do they do it?
Imho a leaf with a 24kwh battery would cost 0.16p/kwh times 24 would come out as £3.84. Am I doing smth wrong?

Octopus Go offers 4 hours at 5p/kWh between 00:30 and 04:30.
Home charger will normally power at 7kW.
So in the four hours you can put 28kWh of electricity into your battery for £1.40. Which is about the same price as 900ml of diesel if the price I saw this morning was right!
If you treat a typical EV as achieving 4 miles/kWh this gives you a range of 112 miles for the £1.40 cost.

This is very interesting.
Old Zoe 24kwh if you charge it not at home it will cost roughly 17-18pence per mile which is the same as a 11 year old Focus 1.0 Ecoboost.
Conversely charge it at home on an economy 7 meter then its 2.5pence per mile or 5p per mile if you charge it at home in the day.
So should you buy an EV or not well yes and no. If your charging at home yes it will be cheaper, if you don’t have off street or ability to charge the car at a tiny rate per kWh it’s not going to be cheaper.
This is the issue of the lamppost chargers those who say don’t worry on street will sort itself out…. It might but it will be more ££

Which car is this? Since Polestar can do 250miles with a 78kwh battery.Octopus Go offers 4 hours at 5p/kWh between 00:30 and 04:30.

. Our tariff is rubbish, and our EV large and inefficient.
Costs about £16 for a full charge of 200 miles. 8p per mile still pretty good for a 2500KG, 400bhp SUV though? Similar ICE car would be costing £50+ at current petrol costs.
If I'd managed to lock in one of the cheap tariffs would have been more like £5 v £50.

64kw Kona/E Niro apparently does 300 miles

Plenty of the Korean EV's and things like the BMW i3, Renault Zoe will do 4+ miles per kW. Our i3 would do 180 miles in the summer from 38kWh, or 4.7 miles/kW. On a cheap tariff would have cost £1.90 or just over 1p per mile in fuel.

So more like £25 for 250 miles, or 10p per mile, which is pretty close to what a decently efficient diesel costs.
Personally I think that's a rip off and the government should be regulating to narrow the gap between domestic and service station prices.
If I was going electric, I would be going the whole hog and powering off solar panels on my roof, removing all doubt about how the electricity was generated and eliminating uncertainty about future electricity prices.

There is a massive cost to build a service station like gridserve. Charging only a few p per Kw would take 100’s of years just to cover the cost of building the place.https://www.drivingelectric.com/charging/1181/comp...

Personally I can see charging away from home becoming very expensive, give it a few years and we will be looking at 50p-70p as a standard (it already is for some chargers with pay as you go).
