Probably at 30% market penetration and when other domestic usage is low..e.g. at 'cheap rate' times.
No, they would need upgrading, but thats something that can be done as needed.
I am sure the same gumenst were applied to the motitr vis a vis the availability of petrol when horseless carriages were first discussed: now we have a multi-=billion pound insdutry tankering fuel around to garages.
At least THEY would diappear from our roads..
you are getting confused. 12 hours at 3Kw is 36Kwh. That is the limit of a standard 13A socket.
60A at 240v is 172Kwh over 12 hours, That is the limit of a domestic single phase supply cabling and fusing, though most COULD be upgraded to 100A.
About one hour at 50-200KW is probably the limits of current battery ability to soak up charge efficiently and safely. THAT needs some custom charging stations probably fed by a separate substation.
If only it were that simple ;-)
Seriously, its all about cost benefit in the end. People who live in towns without the nice off street parking with charge, will find that they have to pay more for motoring: they will either stop motoring, or sort out how to charge, or stay with petrol/diesel.
Your estate agent will specify house electrical capacity and off street charging points as part of the literature, and houses which have neither will not sell well.
Frankly for many people who live in urban terraces, they probably already walk or cyce to te corner shop anyway; there is no reason why their cars could not be kept in a local car park, on permanent charge, ready for when they really need them. Safe from vandalism, and, possibly, the weather.
A lot of people in London do this anyway. Not the charging bit, but they rent monitored off road garaging. If electric car tax was adjusted down, and not too many taxes put on the electricity, it could be made at least no more expensive.
I really don't see a problem except in the transition. It would make in fact the risk of visiting such people MUCH easier, as the on street parking would be available for short term stops.
So? that is not half as lunatic as other greenwash bollocks that is propounded.
And would mean cutting our dependence on the middle east and Russia for petroleum, with obvious advantages. Not to mention hugely swinging the balance of payments away from imports.
when its costing you a quid a mile to run the diesel and 2p for the electric, its amazing how fast peoples objections will disappear...
..even to maybe coal fired stations.
right now we have sufficient off peak generation capacity for a market penetration of maybe up to 10% or more. We probably have grid capacity for maybe 30%.
That's already a bigger potential impact than almost any other 'green' technology has..
If you take - say - 100KWh as being roughly 200 mile range, your off peak fuel costs equate to - at lets say 5p a unit - about £5 a tank..
Now even a 60mpg diesel is currently at around £20 for the same mileage. A factor of four, plus all the maintenance costs associated with an IC engine. And the electric probably outperforms the 60mpg diesel too. Thats the nice thing with electrics. You can get peak power without incurring losses or excess weight in the power train. With IC if you want big power you end up with big components, or highly revving smaller ones, which leads to larger frictional losses in cruise mode.
A 5000 mile a year driver is probably going to save about a grand on motoring costs by going electric. £750 on fuel and about £150 on the service. Oh and there are tax implications too IIRC. Whether the battery depreciation will match IC car depreciation is a moot point, but at least with a battery car a second hand model probably is fixable with just one thing - a reconditioned battery - rather then the zillion little things that can go badly wrong with an IC car.
That's worth giving up a 400 mile range for, for many people. Who have driveways that can take an extension cable..
For those with the space to charge, and who run 2 cars or more anyway, making the small one an electric is economically justifiable already. If the cars were available. I'd buy one tomorrow, if the price was right.
