I saw a YouTube video recently of a guy in California who did not have home charging. He did the 'charge when I can' method. Whenever he saw a charger of any description he plugged in, even of only 7kW for an hour. His general driving was fairly local so no need for getting up to 80%+.
However, I would say that the people who would be able to manage this are to an extent 'intelligent'; i.e. they can think and plan and probably don't lead the sort of busy lives that a typical person in a low income town in the UK does. So to an extent, the inability to charge a car at home will affect EV sales.

It would be interesting to see a breakdown of private to business sales. Looking at that table there's going to be in the region of 200,000 EVs dropping into the used car market year on year if the new sales figures are top heavy with company cars. Those used sales don't count towards the governments 22% target this year and 28% next year. Unless private buyers, who typically buy these ex-company or lease vehicles, can be persuaded where are these cars going to find buyers ?
I'm not anti EV, I really do believe they have a place, but without a ready market how will new buyers be found these vehicles. This is a now issue for EVs from 2021. Dealers will not hold stock that will not sell, they can't afford to. It'll be interesting to see how that is addressed. If you make them cheap enough people will switch but that is going to sting those that bought new.

I know it’s wrong not to care. But, I just don’t. Not even slightly. 😉

Of course you don't, Humph. Hence the endless posting about the subject.

I don’t think I’m even slightly up for first prize in the endless posting about E fricking Vs competition. 😂

Er, the others who post, seem to care...seems odd that someone who doesn't care, posts so much, is all.

I'll hijack an EV related thread if you will permit.... how many kWh can you pull safely and constantly (24x7) from a UK single phase supply? i.e. over 24 hours total how many kWh can you supply/consume?
I can explain.

A UK household supply is fused at 80A or 100A, depending on the local network operator. It’s 100A in my area. Voltage varies a bit too but should be at least 220V. Multiply those together and you get 22kW. Sustain that over 24h and your total draw is 528 kWh. On my E.On tariff that would cost about £123.
BPG can explain how theoretical or otherwise that limit is.

Thanks. Not sure how safe it would be to max it out.
The reason for asking is we stuck with eon when we moved. BG tried to say the handover reading was a lot lower than it was when we moved in. I took photos etc. It has a hassle to sort it and then today eon reversed out all payments and charged the first few days as if the figure was the original BG one. So it basically meant in 2 days BG were claiming we used over 600kWh. Yeh right. What could you even use that for. And they wanted an extra £180 for those first days. Except I'd sorted out BG and if eon took the money then I'd be charged for it and they hadn't even supplied it.
Charging a car would be limited to more like 32A so a third of what you say above. After much to-and-fro I even got a bill from BG for those first 5 or 6 days with the correct opening reading.
And of course we have a smart meter so eon has the correct reading for the first day anyway. Unbelievably bad of BG.

When I moved from British Gas to Eon, Eon warned me that there'd be a slight discrepancy in the handover reading - that I'd pay a bit more to the old supplier and the same amount less to Eon. But it was 10 kWh, so really no big deal. But even smart meter reading seems to be full of inaccuracies: the engineer who installed mine misread the old meter, which would have cost me 1000 kWh if I hadn't sent in a hasty correction.

The 3P 32A socket for my 22kW car charger has a 6h run time. You certainly wouldn't be running it 24h.
In general with 1P wiring any fouling, wear or loose connections can cause heat build up if, for example, you're running a 2kW kettle or 3kW heater. In theory, everything being optimal, there should be no issue.
However, the insulation breaks down over time which can cause the wiring to overheat. You can't say with any certainty without testing. Any wiring over ten years old should definitely be checked before throwing big loads at it. Anything under ten years old should still be under guarantee by a reputable installer.
In short I'd be very surprised, while impressed at the same time, anyone pulling 100s of kWh per day or checking in with the neighbours if they were running a horticultural nursery farm at my expense.
Edit: if I was charging 5 of the EV we have plus working from home, running the washing machines, tumble dryer and cooking a Sunday roast I still couldn't use 250kWh in one day.

I am asking because British Gas has tried to claim the initial meter reading for electric was more than 600kWh lower than it was. At first no problem. Then later they claimed it was such an eon correct. Then eon fixed it for me after many weeks and many calls. All fine until today when again it seems BG has made them change it somehow.
My argument all along is if it was the correct figure on the date we moved in, how did we use over 600kWh in a few days before eon took over. I don't even have an EV to charge and if I let someone charge their car it would be over a 13amp cable.
I am not confident this does not all get redone and they take the £190+ from the account again for this electric.
We've done well in reducing electric having moved here. Dishwasher does not have a short ECO mode so uses more. Everything else therefore the same as we had apart from some lights I guess. We used to use around 4400kWh a year but here it's been nearer 2600kWh for the year. So that 600kWh addition is a big addition.
Previous owners though left an electric patio heater in the garage.... Now that cannot have been cheap to use. It went to the recycling centre.

Over here the calculation is along the lines of 1,500kWh/year for 1 person then an additional 1,000kWh/person so 2,600kWh isn't too far out.

When I check tariffs to switch the assumption for this house is we use over 4400kWh per year. This is not just eon. I think the assumption is based on number of bedrooms for starters.
When I did switch the eon account to here it took a while to argue for a fair monthly payment for what we were likely to use. The computer said it should be much higher. As it turns out we've accumulated even more on the account so the payments recently dropped a fair amount.

It would be instructive to know how much of customers’ money the energy suppliers are holding through arbitrarily high DDs. My £186 a month feels high at the moment but I’ll let it go until I know what the new electric heating does to my consumption. Eon doesn’t know about that — or the PV and battery plan — yet.
Part of my reason for leaving British Gas was the outrageous surplus of my money it built up, then held onto, long after 2022 price spike had passed. Even after belatedly reducing the DD, and taking nothing at all once I’d given notice, they still had over £1000 that it took me two months to get back.
