Bristol diesel ban

Brave isn't the word I'd use .

Every house has a 13A 3 pin plug socket and this can be used to charge your EV.

But you wouldnt want to,

To charge the new Jag Ipace from a 13A socket takes 39 hours...yes you heard right
To charge from a 7Kw specialy installed Home EV charger, takes 13 hours..

This is taken from the Jag official web site....

so whos for a new EV???

The future.. its a long wait..

That has me thinking some.
Is that 2 different chargers, as if you just plug in to the 13A the draw would pop the breaker, unless there is a current limiter. Not a great technical difficulty just a queery.

So what is the current draw while charging from a 7Kw supply?
Shall we assume 20 amps.
That actually equals 4.8Kw per Hr.
At 15.64p (my tariff) that's 75p ph.
at 13 hrs charging that's £9.76

That sounds like good value, how far would that get you, realisitically?

 

[Tonygw]

Yes its two different chargers, a 13A standard charge wont pop the breaker. Most household breakers are 15A so unless you have a tumble dryer etc on as well its fine.
It would be on a spereate circuit also.
A 7Kw charger draws 29A straight from the main house service fuse into a seperate consumer unit for the dedicated charger.

Its cheaper than running a fossil fuel car, but way more inconveneient...
The quoted range of the jag is 290miles par 100% charge
makes your choice. but dont get stranded, 290 miles =145miles each way, otherwise you cannot gte home without charging...

 

[m80]

Actually my description was off, it'd be the 13A plug top fuse that would pop, but as a seperate lower output charger it makes sense.

For anyone only doing 200 miles a day (in summer though I guess) this could be attractive(ish).
Any need for a longer journey and the real car needs to come out.

 

[Tonygw]

Mmm not so sure when you add to that the buying price, that woudl offset any savings completely...

Yeh, but it's saving the planet.
Aside from the bit of pollution to make it.
Aside from the bit of pollution that may cause premature scrapping of servicable ICE cars.
Aside from the bit of pollution to intal an infrastructure to make these feasible in the future.
Aside from a bit of the planets resources being used to make the mo mo and the batteries.
I'll let someone else consider any offset of fossil fuel over power plant generation.

But the taxes will be good for the country.

 

[Bellow]

The first part required is obvious and can be pursued without delay ie, renewable electricity generation that is predictable - read wave and tidal. Do we do it now or do we wait until when we have to we have to do the installation from rowing boats?

Mine does but I'm in a small minority of people who have a garage with power and actually put their car in it so it be very convenient for me. I would use it in overwhelming preference to public charging points which are much more expensive. Lots of people don't have a garage so it will be somewhat less convenient and in some cases impractical where there is no off street parking.

Yes, especially if you live in a high rise building. But how do you connect your Tesla?
What if you stay in the city and cannot park outside your house?

Outside of Chelsea, Tesla owners will seldom be living in high rise buildings

Granted, but even inner cities, who can park directly outside their front door?
How many extended cables will pedestrians have to trip over before the councils ban them altogether?

Good luck with that if you live on the 13th floor of a multi storey block

The answer to that is of course : bollards .

Quite how long it will be until charging bollards are as commonplace ( actually more so ) than lamp posts , is another matter .

I was in Hong Kong a couple of years ago and surprised to see so many Teslas around in a city built entirely on high rise buildings.

No. Not if you live in a block of flats.

Lots of jibber-jabber on the subject.

The point I was, rather poorly, making is that there is already a brilliant infrastructure in place to supply electricity to all of our homes and plenty of other places too. You can't move for the stuff it's everywhere. Shops, street lights, street signs, traffic lights, filling stations and our own homes.

It needs some adaptive work but we've been there before, remember changing the gas equipment in the 70s anyone?

No one is talking about swapping from fuel to electric overnight so there is time for the easy solutions to take place before the harder ones and the technology will advance as more is rolled out. Maybe people who live cheek to jowl aren't to be the early adopters.

Imagine if we had always had electric and someone suggested we start using petrol which needs to be brought in by ship, refined and delivered to special stations around the country where they store this liquid underground for us to slosh into our tanks ourselves?

 

[Dryce]

read wave and tidal.

Might be enough for tidal around Scotland if they are willing to risk the affected ecosystems.

But the rest of the UK? I doubt it.

And is wave that predictable? It does vary and so far has been of great promise but little actual realisation.

I think there has to be a realisation that in most countries EVs need nuclear or fossil fuel plants and massive storage systems to back them unless the government can restrict the demand for power to charge EVs to significantly rein in their use.

 

[Bellow]

Tides are predictable. There is (I was told last week) a turbine off a Scottish coast harnessing the tides to good effect. It was said that wind turbines wouldn't work and they did. The will and ensuing investment (of which there has been little) will see progress there.

Bit late for a nuclear programme given the lengthy gestation periods and while I can see the advantage in fossil fuelled generation in achieving efficiencies above that of IC cars/trucks, they'll be used as a stick by the detractors who will claim nothing has improved (except local air quality).

The current infrastructure just does not have the capacity. I have just been told that I have to inform the electricity generating companies that I am going to install an air heat source air pump because of the extra load on the supply infrastructure - a whole 2.5kW. Add that to the fact there will be no more new gas boilers after 2024 so ASHP use will increase then add every ones EV. I would like to think that someone in government is thinking about all of the new loads we will be putting on the infrastructure but I have my doubts. It is not like you can increase the capacity to an area gradually, the supply infrastructure needs upgrading once, it cannot be a gradual upgrade because that would mean doing the same job multiple times.

I know of a London University that was told that it could not have a new data centre in Central London because the electricity supply capacity was already maxed out so they had to build outside of the M25.

Petrol if it was a new product would sell simply because the energy density is a no brainer

 

[m80]

Wave power is a bit hit and miss, rather like wind.
Tides, apparently no man can stop them, but I'll bet women think they could.

My secondary issue with all of this is that nowt is for nowt. There will be an environmntal cost to transfer demand from fossil to renewable. Production of new kit, instalation, maintenance and replacements, and recyling (or not) of old kit that may have serviced us for a while yet.

If it were objectivley applied to a balance sheet would / will we come out in credit?

My main issue is that not one politician has remotely approached the issue of over population as being the primary cause for all this. Farage was closest, but that's enough mention on this thread, he's history now anyway.

I remember it well and can see the gas man changing the jets from coal gas to natural gas.

I wonder if such an undertaking could be done today without being ruled ruled out on Health and Safety grounds. I think we were a lot more organised back then.

A bit more difficult now as he would need Gas Safe certs for both types of gas,
or the 1st guy removes the original jets and the 2nd guy comes with the replacement jets, a fortnight later.

If you don't buck up your ideas the future is going to be miserable for you.

Depends.

We have rather got used to oil based fuels. The barrier to entry for any other technology has been made higher because we have adapted our lifestyles and economy over the last two or there generations.

So as an example if we had started with EVs instead of IC vehicles then they might be lighter and our usage patterns in terms of commuting and leisure would be different, public transport would have developed differently, and frieght would be substantially different.

IC vehicles might be a harder sell than would appear to be the case today.

There might be enough tidal power around Scotland, but the rest of the UK will see none of it as it will all be sent via submarine cable to the EU when Scotland gains independence.....

 

[Petrol Pete]

Don't the cables lock to either the car or charger? If not, easily accomplished. Brave vandal that interferes with a live cable.

Same vandal who climbs onto a greasy church roof in the pitch dark 100 ft above a graveyard to steal the lead, how about the thieves who throw metal chains up on to 1.1KV power lines to trip the main breaker in the substation then shimmy up the poles to cut the cables down ?

Hand tools are widely available that will safely cut thorough live cables..they know that.
