Over the last few weeks I have read several articles (last one in yesterdays Telegraph) regarding the biggest barrier to the rolling out of EV's .
Although cost of the vehicles was mentioned, the main barrier is charging points, mainly home charges and the lack of main street grid capacity.
Whilst the problem of siting of EV charging points has been mentioned, in several posts at commercial premises, it appears that most residential lines are not able to carry sufficient power to premises that have already carried out suitability checks, so the chances of these lines being able to sustain multiple homes, charging at the same time (usually over night) will be almost impossible.
The answer will either be an upbraided residential supply system (prohibitively expensive), or more combined parking areas with the siting of a multiple charger,, or/and hydrogen powered mini fuel cell charging points.
I wonder if in the future AFC might fill this gap.
Views appreciated!
Rooky..."it appears that most residential lines are not able to carry sufficient power to premises that have already carried out suitability checks, so the chances of these lines being able to sustain multiple homes, charging at the same time (usually over night) will be almost impossible"
Rooky.... Could you provide links to show the above, would be interesting to see.
ie, those streets that do not have capacity to charge at night.
Thanks
Task
PS Biggest barrier to EV......
Over-inflated prices..in order to sell off remaining piston engine hybrid *( self charging nonsense )
Yellow... Why do you think the National Grid have got it wrong ?
1. Can the UK energy grid really cope with a huge increase in the number of electric vehicles being plugged in for charging?
"There are two aspects to whether we have the capacity to manage lots of EVs being plugged in at once – whether we have enough energy and then whether we have sufficient capacity on the wires that carry that energy to where it’s needed"
Enough capacity exists...
"With the first of these, the energy element, the most demand for electricity we’ve had in recent years in the UK was for 62GW in 2002. Since then, due to improved energy efficiency such as the installation of solar panels, the nation’s peak demand has fallen by roughly 16 per cent. Even if the impossible happened and we all switched to EVs overnight, we think demand would only increase by around 10 per cent. So we’d still be using less power as a nation than we did in 2002 and this is well within the range of manageable load fluctuation"

Hi Musc, there's nothing to stop you or I going out and buying a Bosch 32Amp electric double oven, having it fitted and using it when and how we like...that could be around meal times when others in our street are doing the same but that never causes a problem because its been planned for with worst case weighted knn algos, for older streets its even better because those cables would support the inefficient devices of the day three bar fires, storage heaters etc.
You dont need 32A charger at home, in most cases 13A socket is enough to charge overnite for say a 24Kwh EV and maybe twice a week.
My concern is the slow take-up of ev.
And the EV charger.
BB, you remember correctly. AB clearly stated that there was no problem with the national level but that several people had recently raised the local grid issue with him.
He was also clearly not targeting the average household on the street as that would be commercially daft. As has been stated many times, it is much more a case of looking at car park operators, motorway service stations, fleet vehicles, remote locations, offices with many staff etc etc etc
I am not quite sure why some people (not you BB) seem determined to talk down the potential for EV when it is abundantly clear from the logic above and the 500+ potential customer enquiries to the company that the demand is there. The question is whether AFC can become one the suppliers and all the signs seem to be pointing to a "yes" at the moment, albeit a bit later than hoped.
FCI. Correct.
Banana, not many people will need to fully charge their car every day, the talk on here is comparing filling a petrol car at a petrol station where most people would fill the tank from a low level but the reality of charging electric vehicles at home would be drivers topping up after a trip out so vastly different demand on the local grid
Daz, a fossil car mindset its hard to break after so many years of filling...a b c always be charging.
Bananaman, most cars don't do 100+ miles per day. Imo, most don't do 10; just school and the shops. OK there may be some fossil Super Salesmen on the road all day, but the information superhighway has just been demonstrated by lockdown. Weekend in Lake District, yes full charge and another to come home.
I really think the slow ev rollout, and change in habits, will offer a solution.
I have actually lost the point of this subject.
Seem to be missing the point somewhat.
When petrol and diesel engines are no longer produced people will have to drive EVs or an alternative. Presently their is capacity to deliver charge from local distribution for the limited number of EVs and PHEvs. This number is growing exponentially. As a result more vehicle will require charging from more locations.
Either the DN needs upgrading or an alternative solution is required for future demand.
Strange heading...another step up tomorrow. Will be 25p by Tuesday.
The biggest barrier to an EV is the price of a new car.
1. It's not comparable currently with what we are used to driving yet, but this may change if government forces the issue.
2. I'm not sure there is enough choice currently compared with the current petrol/diesel vehicles available to purchase but again that may change soon with the government policy.
3. Range anxiety, will it get me to where I'm going with the current amount of charge points?.. That will almost certainly be announced soon.
4. My personal fear.. What if they break down... An electric engine stops dead, it doesn't coast on. You can't bump start it and it can't be towed, it has to be trailered.. Although electric motors are probably more reliable than petrol/diesel.
You wouldn't want to break down on a smart motorway.. In any lane.
Hi Taskmaster,
Unable to find any links pin pointing the areas, but I presume it is a widespread problem.
I do agree that self charging hybrids are also a barrier, but I think as battery power plus hydrogen will push those self charging hybrids out.
