How Will People Charge Electric Cars If They Dont Have A Driveway

Which is all well and good, but the electricity supply needed for just that one charge point is about the equivalent of the current infrastructure for about 600 houses - think of the equivalent of several substations devoted to just one charge point. And the charge cable would have to cope with (for example) 600A at 1000V.

That's something for the infrastructure people to sort out. It's worth noting that the charge point doesn't have to be connected directly to the grid. Some local storage capacity could be refilled from the grid at a lower rate, including when no vehicles are being charged, and then passed at a higher rate to the charging point. I'm sure the infrastructure people are aware of the issues.

Well at a motorway service station it's likely to be in near constant use for large periods of the day. The cable to the car would have to carry 200 times the power of a cable used for an electric kettle. These are problems the infrastructure people are aware of, but don't necessarily have answers for, -at least not answers which are economically viable.

If you need to be able to charge up to n cars per hour at a motorway service station you need the same amount of energy whether you do it with n slower charging points or n/7 faster charging points. Service stations are likely to prefer the ones they need fewer of because they will be cheaper and take up less room.

Says it couldn't charge at five stations, so does that mean it kept trying different places but the equipment was just broken?

 

It doesn't seem that robust when put to frequent use

Yep. The Cornish news article has more info:

As well as the five charging points in Cornwall which could not be used to charge the vehicle there were another five on the journey from London to Cornwall which could not be used.

 

In Cornwall the electric coach visited the following charging points but were unable to successfully charge the vehicle:

 

Bodmin Business Park – Genie Point – 50kW – machine not working, despite Zapp Map not reporting an issue.

Bodmin Morrisons – Genie Point – 50kW – recognised the coach but did not deliver the charge.

Kingsley Village – Shell – New Motion – Tritium charger – 170 kW – registered coach and charge left on coach but would not charge.

Cornwall Services – Ecotricity – 50 kW – error with the charger, engineer informed but did not work. At 11pm the coach met a Nissan Leaf driver who had tried three other charging stations experiencing problems.

Eden Project car park – Genie Point – 50 kW – recognised the coach but did not deliver the charge.

I can't wait till 2035-2038 when it's decided (officially, we already know it now) that battery EVs aren't environmently friendly as they say now, like they did with diesels & then tell us we need to be buying another fuel sourced car, most likely HCF.

Here's one option.  Pavement channels.

Cheapest and easiest option.

That does say:

The cables are not permanently left in the channel – only when charging the vehicle. 

 

Thats probably the more unsafe option.

 

If you need to lift this thing up and run a cable thought it to charge, eventually either the cover will get bent from all the movement and not fit or it'll be left half on.

Anyone with mobility or vision problems will trip over it and hurt themselves.

 

It'd need to be firmly fixed to be safe, but then you end up with an electrical socket on the floor, which will get full of water and crap.

Electric planes I am.very doubtful off.

 

unless they come equipped with extraordinarily long flexes, to plug 'em in...

It's legal in some local authorities, not in others.

 

With the proper cable covers it shoulnt be a problem, big problem if its just cables lying about. I did read some places are looking at utilising lamp posts and charging from there.
