Slow charging should be around 95% efficient

My I3s has an 11% charge loss.

The Polestar 2 is a bit worse.

I think on many EVs it’s more like 20% with home (7kW) charging. Granny charging in low temps people say it’s more like 30%.

There are a few Tesla chargers that anyone ( without a Tesla) can use, they tend to be cheaper than the non Tesla public chargers.

There are loads, you can now travel from Surrey all the way to Scotland only using Tesla Superchargers.

Pay the monthly fee for the month of your trip and get the reduced rate. I think I paid 34p a kWh.

These are all open to any car.

I measured the I3s in the summer so it could well be worse in the winter, I would need to check.

I'm getting just under 4 miles/kWh, so about 1.8p per mile (home charging)

Even using a Tesla Supercharger is around 10p/mile (depending on time and location) so still cheaper than the majority of petrol/diesel cars.

Had the car for 10 days and the Tesla app is telling me I've saved well over £100 in fuel costs (I have done 1000 miles this week tbf)

Also if the car has carplay or equivalent
ABRP satnav is great
You can filter to use only Tesla chargers
It knows your car battery % and the destination charger availability (with Enode enabled)
All displayed & updated on the cars display.
I understand it’s what is integrated into new Polestars.
(£40 a year to allow it in carplay)
I rarely use public chargers, but only used Tesla ones in my Skoda Enyaq.

Interesting to see other people's figures. By my calculations, our MG4 has losses of around 10-12% with the MG-supplied granny charger, I haven't tried it on a 7kW charger but I'd expect it to be enough better to at least put it on the right side of 90% efficient.

All good info so far.
What is this talk off 19-12% losses charging?

Read up on it here.

It's something no one really talks about

Right, read that, interesting!
Interesting about Tesla superchargers as well.
Are the plugs all standard now? In other words can I plug into any charger?
Also as a lot of my driving will be in Europe, are they standard over there?

EV3 charge port front right?, should be ok on all Tesla chargers.

My Enyaq, rear right (Tesla rear left) on the ‘old’ Tesla chargers it means blocking a space, as their cables are too short.
Was quiet so not a problem!

I had an Uber Kia EV3 the other day and honestly it was much better than I expected.

Don’t they also charge v quickly due to 800v?

EV3 is 400v

OVO Charge Anytime EV add-on means you could charge your car at any during the day or night - you're not restricted to a few hours overnight.
This is dependent on some factors though - excess capacity, lots of wind etc. It's a bit more flexible, and doesn't impact whatever standard tariff you've chosen from OVO.

Yep and sign up to the power move and avoid charging your car in those hours and you get £10-£12/month credit meaning your first 400 odd miles are basically free

Are you sure it was an EV3? They're only just starting to appear and I'd have thought EV3 would be a bit small for private hire.

There are still some CHAdeMO chargers, but I doubt you could find a location without CCS (AC) and/or combo CCS2 (DC) chargers. Never used a Tesla charger, but the plug is the same as the others.

If you drive in Europe, you can cover most of the continent with IONITY (some gaps in Finland and Poland), which can be cheap with the Passport Power subscription (for example, 0.33€/kWh in France). That and the KIA charge card are all you need (the equivalent Hyundai one claims over 800,000 charging points), although you may pay a premium for the convenience of the RFID card if you want to top-up on a slow charger somewhere during a lunch break.

Fastned offers similar subscriptions, worth a look if you don't venture too far into South or East (seem to be similarly reliable as IONITY).

Get yourself on Ovo Powermove Flex as well and that’s a further £12 per month if you leave it plugged in for 6 x 3 hour chunks over the course of every week. 21.6p/kWh home electricity and 7 p/kWh EV.

The EV3 charge curve looks ok up to 70% charge,. I think usually you'd get (without trying) about 400km/250 miles from a full battery before stopping; then you'd typically stop for 25 minutes to get about 300km/190 miles of range.

If you do trips that clearly exceed 800km/500 miles per day routinely, EV6 or Hyundai Ioniq 6 might do almost the same distances between charges, but charging stops would be about 10 minutes shorter. Hyundai Ioniq 5 requires more frequent stops, but charging times are the same as EV6 or Ioniq 6. Still OK for 1300 km/800 mile days.

Hyundai might still offer good deals on pre-facelift cars in stock (if you need to buy new).
