You have been driving for hours, check into a motel and find you cannot recharge your car?
Go across the street to another motel that advertises charge hookups. Just add the cost to your room bill.
Sure. You could pay extra for some KWHs.
Free fuel is really appealing to some people.
If they advertise free charging, then it's not stealing.
I've never seen that, but I suppose it happens. The motel might need to upgrade their service and wiring to handle everyone plugging in. They certainly don't want extension cords running out of doors or windows into the parking places.

This area, a couple of miles away from that picture is (or used to be) one of the car crime hotspots outside London. It is also one of the expensive areas, so most of these properties have been subdivided into flats.
It is also a conservation area, meaning very few changes to buildings/street furniture etc are allowed. For example, the window frames have to be wood; UPVC double glazing is forbidden.
None of these places has any car infrastructure, and finding a parking place is notoriously difficult. Good luck finding a way to charge an EV here!

There are many, many /many/ places in the UK like this, ditto European cities.
It is one example of why Rick C really ought to go and see /before/ he makes up his mind.
It does and we do. Nimbys don't want power stations built at all and market economics in a privatised generation system has resulted in massive under investment. Whilst planned closures have almost all gone ahead new build of power stations has been stalled for nearly a decade.
See fig 1 in this report (which proved to be optimistic).
Engineers have been on at the government for decades Professor Ian Fells used to advise World governments on this and had been pointing out that UK energy policy was crazy since the turn of the century. Earliest one I can easily find is in 2005 - he has pretty much been proved right.
We have a chunk of supergrid spur near us which serves no useful purpose at all. It was intended to take all the output of the proposed Enron power station down south where it is needed but Enron went bust before they even broke ground for the power station.
They might get some new generation kit online in as little as 10 years but the government is so preoccupied with Brexit that basically no strategic decisions on energy infrastructure are being taken. Worse still they are applying installed capacity heuristics that made sense for real generation (where you have real 20MW on tap to use or not) to the installed peak output of renewables where availability scales with the cube of the windspeed or whether the sun is shining.
Brexit itself has screwed up all the heavy carbon users since 28/3 (official Brexit day) they can no longer buy EU carbon credits.
This killed British Steel stone dead a couple of weeks back.
You have to understand that UK streets are fairly narrow congested and street parking very crowded. There are already water, sewage, gas, electricity and cable TV buried under the pavements and roads.
It is a serious undertaking to close a road to make such alterations.

That's what I said below.
I never said free charging.
They have to recover their cost somehow. One way would be to offer charging hookups only in premium rooms. Not everyone will be driving EV's
- ordinary motor vehicles will be around for a long time. They won't need a charging hookup, so there is no need to charge extra.
Anyway, there is no need for your product idea that "cuts off if too many KWH are used in some time period."
Just insert your room key to start the charger. Have it stop the charging automatically as soon as you unplug your car. Add the cost of electricity to your room bill.
This is flat out wrong. There is no PEN in UK mains wiring. Only three phase live and one neutral return are present on the poles.
UK is a TT configuration with *LOCAL* earth bonding at the premises.
The safety earth in the UK is local to the house and has absolutely no physical copper connection back to the step down transformer. Traditionally it was done by bonding to the incoming lead/copper cold water pipe but now that these are plastic it is done with a copper stake driven into the ground. Neutral is earth bonded at the transformer too.
The worst that can happen to the UK safety earth is that it is left floating when cowboy electricians fail to connect it up.
*Neutral* can drift to any of the phases in a serious fault condition.-- Regards, Martin Brown
It is barking mad but it was announced as official government policy less than a week ago. A parting shot from the worst Prime Minister the UK has seen in living memory (possibly the worst ever - although there is scope for that to change when Boris the Buffoon gets the job).
She wants to be remembered for something other than total failure to deliver Brexit and government bills defeated by the largest margins.

The UK implementation of "smart" electricity metering like the DAB radio is so utterly cocked up in the UK that it could be used by a hostile state actor (or fairly advanced hackers) to thrash load on and off the system in an extremely destructive way. They are still rolling out the defective smart meters knowing that they are a disaster.
They fail and become as dumb as a rock again if you change supplier and the cryptography on the generation 1 stuff they rolled out can be beaten by almost anyone who wants to do it. I refused to have one (and couldn't get one anyway since there is no mobile phone signal at the meter).

He seems to have assumed a two phase supply to the home which is almost never the case in the UK. All domestic premises are single phase and usually 100A main fuse (although older properties may be 40, 60 or 80A.
240 x 100 = 24kWOur village hall has two incoming phases 100A but it is unusual. Farms are often on three phase to power grain driers and the like.

They do that a lot in ikea.
It wouldn't happen as much if they didn't put the charging spaces next to the door.
Pretty soon they are going to be in trouble as the spaces are too small for disabled spaces so they have no charging spaces for the disabled.
I don't think that is correct. If the car is "double insulated" then almost by definition that means the chassis will *not* be connected to a ground pin?

No, can't see that being looked upon favourably. There are a few kerbside charging points on the street though.
Here is a relatively new example:

Wonder if the council has been sued for installing these trip hazards yet?
Only with subsidies. In midsummer you get plenty of power during long days but in mid winter you only get 4 hours of sunshine on a good day and the sun manages a peak altitude of 15 degrees at London and 6 less at Edinburgh. Solar powered "Please go round the dangerous bend" signs in the UK are typically dead two hours after sunset in mid winter.
On a frosty winters morning they are worse than useless.
UK latitude is too high for solar PV to make any sense beyond harvesting the government renewable energy investment grants. Wind power is a somewhat better proposition but not always available. The killer is that their output scales as the cube of the windspeed and the coldest winter days are very often flat calm.
We rely on the light summer loading period to keep the electricity generating plant serviced. If you run everything flat out continuously (as we are doing at present during every winter cold spell) then eventually you will get serious in service failures.
I am not as pessimistic as he is, but the present UK situation is pretty dire with no-one in government doing anything useful at all. They are consumed by Brexit related in fighting in both the main parties.
As things stand there are not enough EVs for it to make any difference when they try to charge. It may mess up traffic light timings longer term though as the grid uses the light night time load to catch up on any accumulated lag due to peak load frequency droop. This tended to annoy astronomer back in the old days of mains synchronous motors.
You seem to know nothing of UK constraints or wiring practices.
That is pretty much what happens in the UK when they move in to alter the infrastructure. One of my local routes is presently affected by a weeks closure for emergency telecoms work. It is causing chaos.
A previous Prime Minister John Major was so exercised by this problem of utilities digging up the roads that he set up a "cones hotline". It didn't last long and was a complete waste of time and money.
The problem will be who pays for it. Government certainly won't.
-- Regards, Martin Brown
Their payback is severely compromised by the high latitude of the UK.
In summer they are OK with our long days but in mid winter when we need all the power we can get they barely manage 5 hours at less than 10% of peak rating. The sun is very low barely getting 15 degrees above the horizon at London and 13 degrees at Edinburgh. It is often cloudy.
There is a roughly 10 fold loss between summer and winter output.
He was an adviser to the UK government until he sadly died a couple of years back. The book is on sale but he made the content freely available online. It is a fairly articulate summary of the science behind the various technologies that might be used to address climate change. It is generally fairly reliable although it will become out of date now it is no longer being maintained.
But you are barking up the wrong tree and refuse to listen. The problem in the UK is not with the mains distribution infrastructure but with the long standing lack of investment in new generating capacity.
You refuse to listen to anything that doesn't fit with your preconceptions.
The problem only exists in your imagination or when something like a major gas supply failure changes the local load so that everyone turns on multiple electric fires at the same time.
The generating side watches major events to have hot spare capacity and the very fast start pumped storage system all ready to go when there is a tea break. Distribution has never failed on any of these occassions.
Not a large increase from summer to winter, but a more significant evening
Possibly. Certainly unusually cold winters will stress the generating capacity past breaking point. It is already dangerously close to the safety margin in winter and has been for almost a decade. It very nearly went pear shaped during the Beast from the East in March last year.
Shedding industrial loads and paying them to stay off is no way to run an electricity *generating* business.
You seem to be unable to understand the situation in the UK.
Its government is so preoccupied with Brexit that nothing else gets a look in. The electricity MFU has been building for a while. Planned closures and mothballing of plant that is unprofitable to run keeps going apace but new build of generating capacity is stalled. eg
There are several others in a part built never finished state too.

Dumping more CO2 into the atmosphere than you need to won't "Destroy the Planet" but it will make it less suitable for human habitation.
There are activities that dump CO2 into the atmopshere that are harder to get rid of than driving around in a gasoline-powered car, so getting rid of regular cars is a fairly high priority.
John Larkin's enthusiasm for "destroying the planet" is "catastrophism" which is one more of his intellectual errors.
So does filling up a gasoline-powered car.

Not sure what you mean by "on the poles". I have talked to many hams and l ooked at any number of web sites. PEN is a combined neutral and protective earth. This is done to save on the cost of the wiring. Only when it reac hes the junction box in the home is the protective earth separated and run through the home. To keep the circuit safe in the event of a break in the PEN the various metal facilities in the home are "bonded" to the common gro und/neutral connection this junction box. This is designated TN-C-S. Ther e is no earth rod required at the home. I am told this is a very common ar rangement.
In some cases, yes. TT is not universal in the UK.
I don't get why you are adamant that TT is the only system in the UK.
