Site electricity usage - recharging electric cars???

[chrisgreen]

You are not paying for regular mains at fast chargers they are DC. When fast charging, the AC to DC conversion built into the car is bypassed. I have no idea how much these chargers cost, but no one is going to invest literally thousands of pounds for a fast charger then only charge you the cost of the unit price of electricity.
I only use fast chargers on a long journey. We drive a Tesla Model 3, the Tesla Superchargers are simply put, brilliant, and are way ahead of any other charger network.

And us plebs can now use some of those superchargers i can use tesla superchargers at Banbury in my Corsa E.

How about ‘can be erected in 9 hours’ for starters…….?!

Erm. What is hard about that. I presume they are talking about onto a pre-prepared site. You know the concrete has already been poured and ducts in place.

Drop off charger heads and storage unit. Run cables. Connect.
Solar array being set up by a different team at the same time, Steel I beams bolted together and solar panels installed on roof.

Seriously 9 hours seems perfectly respectable to actually do the install. Most time spent on modern builds is down to bureaucracy and planning BS.

I suspect they have a system similar to this.

Ah, I see…..‘weasel words’ being used (but not by you!) - I should’ve realised, I suppose. Ok, on a non-prepared site, a 9-hour construct = no chance!
Back to the physics:-
How many solar panels would it take to ‘fully-charge’ an EV in three hours?
if 4 panels gives 1kW (approx.) on a sunny day, how many would you need to ‘fast charge’ one EV?
7 to 10kW would seem to be required would you say, which would give 25 to 35 miles range added per hour, or am I being too pessimistic……?

but these pop-up sites are not relying on solar they are mains connected.

It doesn’t say that in EzeeRider ’s post above…….

As AndyPK states. Nothing about that in the OP. No details at all in fact.

There was not enough info to make a pronouncements on it either way.

 

[EzeeRider]

i did say I had mised the comment about it being connected to the electricity supply. Too many commenting who have not seen the article, if I could find a link to it I would publish it.

Not Weasely words. That is normal in the industry.

The maths is fairly straight forward. The most common battery pack size I can see is 50KWh. So 50KWh / 3 = 16KW of power required.

I would suggest this is a battery backed up system, so an excess would be required to charge the battery as well as charge a vehicle.

The canopy size would have to be considerably bigger than a parking bay to do this. BUT still nothing saying it is not possible as far as I can see.

We are lacking too much information to be able to make specific claims or do calculations. He didn't even mention the firms name etc. So we can't do independent checks on this

I don't know where you get that it is connected to the grid from? I suspect it would be connected to the grid, not that we have no definitive statements either way just assumptions I think???

The pro EV brigade will always look at only the positive points and ignore the negatives
The anti EV brigade will always look at only the negative points and ignore the positives
No help at all to those prepared to consider the change,who just want the truth

 

[peterc10]

There is nothing new on this earth.

The same sort of arguments were being had 120 years ago as to the impracticality of the internal combustion engine compared with the infrastructure in place for steam and horses.

The big problem with this little debate is that we don't have any of the facts. so we are basically arguing about something none of us knows any details about Got to love the internet

The biggest problem I can see with that system is that none of those cars are electric.. to be fair there doesn’t appear to be any bay markings, oh and they look to be 7kW chargers.

 

[nicholsong]

While these discussions might be relevant to current EV technology for cars, and I accept some members have them now or might have in the future, the discussions seem a bit premature for those of us with only MHs.

The really viable van or lorry chassis which could form the base vehicle with adequate range for a MH is not really in the concept format yet.

Maybe, instead of discussing what might not happen for MH EVs we should be letting the converters know what our specifications would be for buying any EV from them, including not reducing the quality of fixtures and fittings to compensate for battery weight.

Part of the ongoing practicality of MH EVs is the acceptance internationally of any weight increases for vehicles and drivers' licences. What good is any MH if one can only drive it in one's own country? Anyway would MH converters be interested in limited markets - they need all countries to agree and I do not see much movement in that direction.

 

[AndyPK]

Absolutely agree, nicholsong !

If you are referring to the picture I posted. That was just an example of the construction techniques that allows a 9 hour install. It was not from the company concerned who we still don't know who it is?

 

[AndyPK]

I’m guessing that this is the company……..

Currently on a site in L’escala. Last night a guy in one of the adjacent bungalows plugged his X5 M Sport into the same bollard that we’re hooked up to. What’s the chances that reception knew nothing about it. Bet this sort of thing doesn’t last long.

I've had a long held view on people who use electricity for every thig on site "coz I paid for it". But when it comes to leaving fan heaters on in awnings when going out, heaters on in van/caravan 24/7 and opening windows to cool off ( yes I do know people who do)

In response to the original post, I would leave the use of site EHU to the site operator/owner if they don’t want people charging cars or using outdoor heaters fair enough. Life is hard enough without worrying what other people are/are not doing.

Well maybe site owners might be interested in what the customer base think before committing capital to a project that may not make the return they expect.

Was that a bollard that you were paying for by Kwh?

Is that possible yet!!

It used to work with trolley buses……ah, but that was overhead cables wasn’t it….?
