Car EV charging point advice

Moral of the thread then.... Get yourself an EV before someone notices they're a) lovely to drive and b) cheaper to run than taking the bus.

Self-driving cars could well be priced out of existence by the lawyers.

If a person is driving along the street, and a child runs out in front of him, he may almost instinctively swerve to avoid him, and have a head-on collision in which several people die. Possibly including him.

If a self-drive car is driving along the street, and a child runs out in front of it, the car will do what some software engineer sitting at a desk decided it should do. A programmer would have decided, in advance, who will live and who will die. Possibly including the owner of the self-drive car.

Just because the car's rules were decided in advance doesn't make them wrong. In fact it makes them more likely to be right. Also decisions like that are made by product not by engineers.

Good luck then, Mr Product, gripping the rail because your car deliberately chose to kill the owner and 3 other innocent people in preference to someone who made a mistake. Or because it deliberately chose to mow down a child in preference to .....

I'm not being some sort of Luddite here - I think that it is going to be a legal minefield, and those who try to brush the issues aside are only fooling themselves.

Another potential problem - if an aircraft type is found to have a fault, it can be grounded. Airlines then scrabble around, and after a bit of inconvenience, everybody is flying again pretty much where and when they wanted.

What will happen when (and it is when, not if) millions of Ford Automacars (other self-driving vehicles will be available) are taken off the roads and millions of people lose their transport? Welcome to kerr-ching world for class action lawyers.

By far and away the biggest hurdles for self-driving cars are not technological ones - they are legal, regulatory and societal.
 
Bet you are wrong on that bas
Dunno, the only think stopping them now is identifying the "thing" to tax. When someone manages to explain that these things aren't "clean", just moving the coal and gas burning "somewhere else", then I expect we'll see a bit of a backlash.

A few times I've thought that they would suit our needs (both myself and SWMBO) for the majority of our journeys. There is a slight problem though - they need charging and many times we're lucky if we can park within sight of the house, let alone close enough to run a charging lead out to it.

Which puts in mind an interesting scenario to think about. In some parts of Manchester (for example) there's a lot of new apartment blocks gone up - what we used to call blocks of flats, but posher and without the council estate undertones :whistle: I've noticed that these typically have large garages at the bottom.
So suppose that EVs really were the best thing since sliced bread, they sort out the battery costs, and before long everyone is buying them. What's more, they sort out the "smart grid" (properly, not these Stupid Meters going in now), so the cars can all charge overnight. Lets say there are (say) 100 apartments in a block, and 50% have an electric car. Sometime during the night, that's 50 cars to charge up. What will melt/fail first in the lecky supply to the building ? Assume all the neighbouring blocks are doing the same thing.

They might be in-appropriate for a situation the designer / programmer was unaware of. Aviation's "perfect" auto pilots have caused aircraft to crash or they have allowed the aircraft to become un-stable, realised they are in trouble and have disconnected themselves, handing control to the human pilots. Most times the pilots have been able to recover the aircraft into stable flight but not in every case. After those few tragedies auto pilots have been re-programmed and pilot training has been extended in how to cope when the auto pilot decides it cannot cope.

That can happen in aviation as the number of incidents is managable at a few hundred per year. The number of incident that would occur on roads populated by driverless vehicles would be hundreds per day and many important lessons could be lost in the stacks of reports.
 
I have no idea if this is good advice but one of the local e-car owners used it when putting their charger in the garage

Yes, I had mine (3kW as that's all the car can take) put in by Chargemaster when the cap was still £700 - so it was completely free. Charges in about 4.5 hours and gives me 40ish miles, which is enough for my day-to-day usage,

I think you're underestimating the percentage of accidents that happened due to human did something stupid.
Replace those with computer says no type of errors, and as long as the overall number is better, we can switch over. Then we can spend the money saved on making the system even better.
Agreed with bas that the difficult parts are not technical, but then most problems in software/tech are human not technical. Software without the human element is just theory.
 
How does the pricing of this work out?

What I mean is, in the home gas is far cheaper than electric - three or four times cheaper?

Yet here we have someone getting the equivalent of two or three gallons (£13 or £19) of petrol for £2.50 of electricity.
2 or 3 gallons of petrol is 86.4 or 129.6 kWh.

£2.50 of electricity is 20kWh? 25? 39? (We don't know what moog pays per unit, or if he uses E7 night rate stuff to charge his car).

I've never dug deeply into all the data out there, but there is this:


So 3 - 3.5x as efficient?

3 - 3.5 x 20 - 39 kWh of electricity gets us 60 - 136 kWh of petrol. It's in the ballpark.
 
In terms of comparing energy sources, that's "a bit misleading", as are several other bits of "information" on that page. It's the sort of tactic used by the green lobby.
In this case, it conveniently ignores the conversion efficiency converting the chemical fuel to electricity at the power station. So lets say we were burning petrol at the power station, what's the efficiency there converting to lecky ? I suspect that from fuel to wheel is not much different.

From burning whatever fuel is used at a power station to electricity in the home, about 2/3rds of the energy is lost, making EVs no better than petrol vehicles in terms of energy used.
It's also why electric heating is a total bust in terms of efficiency, despite what some manufacturers claim.
