We know the off peak rates make evs significantly cheaper to run.
How can we ne sure this will stay the case.
At 40pper kwh it's not that economical v at 8p per kwh.
Have we some crystal glass and like to share thoughts.

At 28p/kwh mine has cost £577 over 7000 miles. But 30% of my electricity has been free, so let's call that £820. Or call it £570 for 5000 miles.

My wife's Auris has cost £4138 in petrol over 20k miles.


My first Disco cost £1200 over 6500 miles.

My second Disco cost £2190 over 7200 miles.

My 440i cost £3250 over 15700 miles. Average price per litre £1.23

Taking the 440i as of similar size and considerably lesser performance, I make it that electricity would have to be around 53p/kwh for the electric car to cost as much to move. (This is taking out the free electricity and assuming I pay for every mile)

I don't have a crystal ball, but my feeling is twofold - one, that electricity will come down in cost from today's prices; two, that if it goes up considerably then it is likely that petrol/diesel will be doing something similar.

Now, imagine the octopus boys' costs. My deal is not especially cheap. On octopus i think I would have paid around £140 not £577.

At 40p / KWH its still better with 55kwh x £0.4 = £22 for 270 miles.
Call it £44 for 540 miles that still cheaper than any petrol fill up of the last 5 years for me.

Saying all that, that's the absolute doomsday scenario .... which really isn't very bad at all.

Even during the energy crisis didn't EV night rates peak at 12p? Also all they really did was stop new people joining them.

Currently they're 7.5p and about to dip come July no doubt, I'd suggest only to 7p or such, and TBH at under a fiver already its all arbitrary.

My 'blended rate' which on my bill averages out your EV (7.5p) and your normal domestic rate (41p) kwh price is 22p based on real usage so yeah I'll take that all day long.

Final thoughts I'm afraid wont be popular, like many of my M car affordability comments. IF this is really a serious question / criteria..... then EV isn't for you.

Interesting...I was thinking for a realistic scenario eg an ev like an ipace and 90kwh and 240 miles per charge £36 at 40p/kwh.
Ie 500 miles @ £72
Which in a 32mpg car with diesel prices 500 miles aro£1.35 is £95.
Still better but not that much savings
At 8p its a clear choice. At 40p it's blurry but I suppose we are aware of that.

[robbiep]

Currently (excuse the pun) we've been paying virtually 0 pence per mile for our EV, as we've been charging the battery at weekends from the solar panels and battery.

Meaning the 10-12% ROI that we had before an EV is going to be even greater now.

I don't trust low fuel prices..expecting them to go up too. Why can't you get the cheap electric deals?

[Nibbles]

I just moved my tariff to an EV one with EDF so it's costing £4 to fill the MY up overnight and do 220 miles as opposed to using the 5 series at £85 to fill up and only getting 300 miles out of that as we're mainly doing short journeys at the moment.
I still think buying an EV is a bit of middle class self taxation. We don't do enough miles a year to really make up the price difference with pence per miles difference. However with a salary sacrifice and BIK it cost no more than an ICE car to get a lease so a no brainer.

If a 90kWh battery is only giving 240 miles range then that's the real problem - even if the usable battery capacity is 80kWh then that's a poor 3 miles/kWh.

I think this is the problem with a lot of the big SUV EVs - the cars are just too big and heavy to start with, meaning they have to put big (and thus heavy) batteries in them to get any sort of decent range figure. So you're having to lug half a tonne or more of battery (ipace battery weight is quoted as 610kg) just to get the energy to ... carry all that weight a reasonable distance

Smaller cars are far better as EVs - our e-Golf has averaged 4.5 miles/kWh in the last 4 months.

3 miles per kwh is about the norm for an iPace in my use. And I'll happily drive it at that over a Tesla that does 4.... in the same way I would choose a 3.0 Audi diesel over a 2.0 Mondeo diesel and accept the efficiency losses.

Its a car first and an EV second, and its a bloody good car, that happens to be electric. That works for me...

314 miles this weekend and it cost me about 28 quid. I'm happy with that. Quick, comfortable, quiet, roomy, good looking - you could say grace, space, pace and pretty cheap to run.... works for me!

More of my usage is not the car. It would not save overall to move from my fixed rate

I think we are with EDF so will look into there off peak EV tariffs

Bingo.
But the Modlel Y RWD is very efficient for a big car and the weight is closer to some BMWs than many are aware!

MY RWD 1929 KG
M4 XDrive 1775 KG
530D Touring XDrive 1875 KG
X6 M50i 2240 KG
340D Touring 1875 KG

Not all EV are heavy.

Buying an ev for its weight is like buying a 320d efficient dynamics for its lack of features and for its efficiency ETTO I guess(as someone who had the 320d Ed and put 128k happy miles before selling it on..at that stage of life I was happy with it when you're 28.. mpg is important!).

Again..useful parallel thinking....I do 15k plus miles a year..plus have a hot tub where kids and me n mrs mess about etc.. summer holidays schools close next werk so even more..currently at flat 40p per kwh..but which can be programed to heat up between 12am-4am with proper insulation covers which I have purchased.. and that could be an idea...I think I may stand to gain quite a bit monthly by a holistic review..

Although in fairness 1.9 tonnes for a 3 series is bloody heavy!

My model 3 has 20,500 miles on it now

Total charging costs to date are around £150

Yep. I'm not suggesting anyone buys an EV for its weight but to outline the delta is not so much.

You seem to know what you're doing with you 40p kwh assumptions so I'll depart. Good luck.

[isleaiw1]

So I dont load shift - frankly cant be arsed to be messing around with dishwasher and washer in the small hours to save a few pence - but my average rate on my latest bill is 13.32p per unit. That is despite forgetting to set the schedule for son in laws car to charge at cheap rate and so adding 45 kwh to his Tesla at peak rate..... I do use Octopus Intelligent so I sometimes get 12 hours at cheap rate whilst my car fills to the required level....

I am a single bloke though living in a 2300 sq ft house, my usage is probably not normal.... 72% for charging car I reckon!

Thanks for your suggestions..i learn a lot from around here and Do Not Depart...!
Efficiency can be linked to shape and features sound deadening etc which are different for different cars..

[TimMcC]

My average for last month was 10p. Two EVs.
