The limitation is the house's ability to supply more power, not the car's ability to consume it. Lots of cars will AC charge at 22kW, others at 11kW, almost everyone is unable to supply more than 7kW.

For most people, it's an irrelevance, they don't need to charge faster because they don't consume enough energy daily to need more than they can stick into the car in 6 hours.

Just reading Mammasaid's post it seems my answer is in there.

If the car is basically empty and needs 8 hours, starts at 6pm, and so overlaps the guaranteed hours, then the house and powerwall are at 7.5p and the last 90 minutes for the car, and only the car, are standard rate.

The way to beat that is to set the charge target for the car to, say, 60% on the first night, and then back to 100% for the following night.

Or set up OIG not to charge when it isn't cheap rate.

But then I lose the benefit of running the house all evening at 7.5p?

Curious to see how this works with Intelligent Go.

As it stands if I plug in at 6pm and the car starts charging, the whole house swaps to 7.5p. Then between 2330 and 0530 the guaranteed hours are also at 7.5p and that's when my Powerwall is set to charge.

I don't want the car eating the discounted hours in the evening and then the Powerwall charging at normal rate. I expect that's not the way it'll work but I'd like to find out.

It’s all that most people would ever need. For me it’s roughly 60% charge or approx 160 miles at a cost of 2 p/mile. Any extra would be charged at 8 p/mile.

Exactly. It's all good MB. For what it's worth, I think people are too harsh on you as you can't help it, you're just trying to help.

I don't make (or as far as I understand it, break) the rules. smile

As I understand it, the real crims are setting their EVs to charge very slowly, so it takes forever to fill the car and in the meantime they heat their houses with 3 bar electric fires! smile

My car charges at the 'standard' 7kW.

During the guaranteed hours, Octopus are making hay from my Powerwall charging, because they're always getting paid by me for selling it, and also often getting paid by the suppliers for taking it. Good business!

No, they've said you will be able to set it to stop charging once your 6 hours is up, whenever that is.

Ah! Brill, that works fine then. I sometimes use a whole sparktank in a day, but never two days in a row, so splitting the return to 100% over two days has no impact.

I've no problem with Octopus making this change if a number of customers have been taking the piss.

Same here. It was clearly not sustainable for them with too many “gamers” taking full advantage. I never bothered to give it that much thought. I just plug it in and leave it to do its thing. The dishwasher and washing machine are 24-7 ops in our house!

Me too. It's nice to see the car start charging as soon as I'm home, as dinner and TV and a bit of electric heating will be effectively free, but we can't be arsed to load-shift domestic stuff into the night. Our electric bill, including running two EVs for about 30,000 miles, is about £750 a year. Albeit with some expensive PV gubbins and a PW.

Honda bringing a (sort of) EV Kei car to UK with the Super-N

It doesn't quite meet Kei car dimensions on width due to wheel arch extensions, wider wheels and suspension mods all with the intention of making it a fun car.

The trouble with Kei cars is they tend to be very boxy these days. If they're going to bring Kei cars to Europe something like the Dihatsu Copen looks far nicer.



I saw a Fiat Topolino the other day, it is not a pretty car

But that's not a Kei car, it's a reskinned Citroen Ami, i.e a quadricycle, limited to 28mph.

Just like the Ami, challenging looks.

They have always been going up since I started driving, it's nothing new. I don't even look at prices when filling. Couldn't tell you how much a litre is.

Would be more annoyed if I was limited to how much fuel I could put in my car when filling up.

MB instructing the proles on how cheap petrol is. He is, after all, considerably richer than us.

Why worry about petrol prices? There is nothing you can do about them!
