Cost of juicing an electric car?

Short answer - 9p per mile for a T3LR @ £0.28/kwh and a heavy right foot

There are some free public chargers about and some people can charge for free at work so the floor is literally 0p per mile. On the other hand, Instavolt have just increased their price for rapid charging to 66p per kWh which is about 17p per mile. 40mpg at £1.75 per litre is about 15p per mile.

Anyone with home charging and a reliable smart meter signal can sign up for 7.5p per kWh overnight charging which is roughly equal to 2p per mile. I'm averaging about 1p per mile with a mix of 5p per kWh overnight and free charging from solar and at supermarkets. 

Would also be helpful to point out that with the split tariff you are penalised during the other 20 hours which are not 7.5p/kwh, otherwise your advice may be misleading? Someone could have a 4 bed house with 5 children and an EV that just does 50 miles/week school run....split tariff not the best for all...

Yes - I am that saddo that records every fill up in a spreadsheet. 😁

@Jenni_D let's test your sadness. Can you beat going back as far as June 2007  

That's nothing

My pence per mile spreadsheet goes right back to my Rover 414 SLi collected Saturday 19th December 1992

I had a 1991 214SI as my first company car, you must have had luxuries such as electric windows in the SLI?

Someone was saying it would cost them £19.00 to charge a EV6. Which sounds a lot, they were not on a cheap tarrif, when working out. 

But that would give them 300 miles. If you take £1.75 a ltr & 50 MPG for fuel that is £48 for 300 miles. 

That is going to require some massive price increases to get parity between ICE & EV on home charging.

£19 is very unlikely to get you as much as 300 mines in an EV6. I don't drive one myself but OTE you should multiply official EV range by 0.7 to 0.75.  I think EV6 official range is 328 miles so more like 250 actual.

EFW.

Those were the days 😃

Currently the cheapest rapid charges seem to be at Lidl which are 28p KW. That’s cheaper than my home tarrif now!

On the contrary: if you're able to shift 33% of your usage to the off peak window you'll actually save money on your domestic usage. And, at ~ 40p per kWh, the current Octopus Go peak rate represents the lowest fix available right now by a considerable distance.

My off peak usage is 48% of our total usage if I exclude our battery system (which not many people have) - that is just the EV, I don't delay running the washing machine, dishwasher etc.

When my wife changes to an EV as well next year, that will increase to about 65% of our total usage.

In reality with our battery system 99% of our total usage is charged at off peak. People need to start thinking about the whole energy set-up, not just the cost of EV charging in isolation - there are so many options available. When you will eventually be able to use your EV as battery storage to run the house, then off peak tariffs will be even more important.

I can't have a home charger, and am reliant on public charging. In Scotland, where the prices are largely set by local authorities. Ours is currently 24p per unit. I'm getting 4.1 miles per kwh, so 5.8p per mile. 4100 miles at a cost of £240.

Thanks ComicGeek, that's a perfect example of when a split tariff is advantageous. Petriix in your posts you do not explain the need to move much of your domestic electricity usage to middle of the night or to store it to make the split tariff financially adventageous. I have no beef with split tariffs, only with posts that are misleading because they omit vital information. It's not helpful that until challenged you post only the facts that support your own point of view. Not everyone reading these threads may be a savvy as you or I.
