Public charge cost calculator
Discussion
Zapmap has a handy calculator for working out the time and cost, sadly for me in the South East UK and the areas I visit only Tesla really has the performance for my public charging at the moment.
There are superchargers on the routes I travel, or not too far off them. It's faster charging and a lower cost.
I'm sure it will improve, but the Shell garages I use on the routes I travel only have 50kW charging and the cost is 85p/kW currently
For an id3 it's £30 and 40 minutes for a 120 mile charge, compared to £20 for the same distance using V Power in a golf.
There are a handful of council chargers around, but the ones most local to me are supposed to be 20kW but only average 15kW in actual use. Many of them are 7kW! Not much use when you are stuck in a little country village for a few hours.

Makes very little sense to run an EV on public charging as the cost is a fair bit more than fossil fuels, particularly rapid charging on motorways
If you can charge at home it's relatively easy to get fuel cost to <5p per mile without affecting your other electricity usage (OVO Anytime) so if you can do this an EV can make a lot of sense.

Most manufactures (and some private campaigns) that offer reasonable charging contracts if youre going to use public charging frequently.
My BMW charging plan offers £10 a month fee, which reduces IONITY to 26p, which is really very good if you're doing the miles (this is just an example).

Yes, it’s just about doable where I live with a Tesla and comparing running costs to a fast ICE car, but comparing the very similar performance golf and id3 it’s 50% more for the EV with public charging. blank said:

OVO quote wouldn’t actually show me the cost/kWh….but did suggest my usage would be £411 pcm If you can charge at home it's relatively easy to get fuel cost to <5p per mile without affecting your other electricity usage (OVO Anytime) so if you can do this an EV can make a lot of sense.
Currently on Octopus Go….4hrs at 9p/kWh, the rest at 28p….so yes, with home charging it is easy to be (in our case) about 2-3p/mile, but without that ion, things get a bit more pricy…

That sounds good, local costs in the nearest council car park have shot up. My BMW charging plan offers £10 a month fee, which reduces IONITY to 26p, which is really very good if you're doing the miles (this is just an example).
A few months ago the 20kw (actual 15kw) chargers were 26p/kW but are now 57p/kW and you have to pay for parking on top while you are there. There are only 4 charge points for a town of 25k people, none of the local supermarkets have points yet.
The 50kW chargers nearby seem to be around 80p. The nearest motorway gridserve is 70p for the same speed.

OVO is 32p day and 20p night and then 10p for car charging providing the car or charger is compatible. The standing charges are a bit higher but are balanced by the lower rates so before the car charging it's pretty much even between the 2 tarrifs with OVO being cheaper as usage increases.
Car charging is something like 20-25% of my total usage.
The premise of the OVO deal is that it's a bolt on to any tariff, so your other rates don't increase.

So am I right in thinking that if using public chargers it’s a lot more expensive to run an ev than a ice car?
I filled my car up and it cost me £100, I’ve done 600 miles and will need filling in about 50 miles. So 650 miles for £100.
Aswell as the initial cost / monthly cost of buying an ev how is this marketed or is it just a case of the cost of supposedly saving the world?

I would imagine the intersection of those who rely on public chargers and have regular high miles must be quite small. Most homes have off street parking I think?
I currently live in the city without a charger, but spend very little on charging, as I do less miles. Compared to deprecation and tyres, fuel isn't a major cost unless you are doing big regular miles.
I do occasional road trips with superchargers, which make up a big chunk of my spend, and that hasnt really changed from when i had home charging and had higher commuting miles.

Keep in mind it looks like they are using summer ranges. In the winter, it will cost a fair bit more.
This would be on a 7kW charger, which I would need to add a parking cost of £12.00.
On a 150kW rapid charger
180 miles from 78 kW? Are they really that inefficient in the winter (2.3 miles/kWh)?This would be on a 7kW charger, which I would need to add a parking cost of £12.00.
On a 150kW rapid charger
It also isn't taking into account the minimum 10% charging losses, and is the charge curve so bad that even on a 150kW charger you're looking at 1.6 hours for a full charge?

Not all chargers cost the same, and not all EVs use the same amount of power to move them, so some would be cheaper.
If you take mine, for example, to do 650 miles using public charging would cost around £234.00 on a rapid charger or £166.00 on a fast charger in winter.
In the summer, it would cost around £161.00 for a rapid and £107.00 for a fast charger (11 Hours)
You really need to be able to charge at home. It makes things much cheaper.
To travel 650 miles in my car on the capped rate would cost £58 in the summer.

Yes fast chargers are around 75p per KW.I filled my car up and it cost me £100, I’ve done 600 miles and will need filling in about 50 miles. So 650 miles for £100.

I’m on Octopus Agile so variable rates but I charge when it’s 10p or less.
On Octopus off peak it’s 7.5p. So 10x the cost if you use a public charger.
A hell of an increase if you have no home charging.

They can be worse., I've had down to 125 miles when the weather has been freezing, and the car hasn't moved for a bit

On a 150kW, the car shows from 20%-100%. It would take 1 hour 45 minutes, which would probably take longer.

It depends what you're comparing it to... my EV replaced a 4.2 V8 Range Rover - which was thirsty with a fairly low MPG. My Tesla would continue to be cheaper to run if I used public chargers. But for many it would be marginal or worse.EV's only really work if you can charge from home.
Interesting to read the costs here on using public charging - bit of an eye-opener. It underpins my view that the EV policy from government is entirely wrong when 40% of UK homes do not have off an street charging facility.
