EV charge times

I can't imagine working on an EV is any more dangerous than working on a petrol car 

I imagine that the battery voltage could be lethal to the great unwashed doing diy ………. and others. 

Is it any worse than DIY house wiring?  All the high voltage wires on an EV should be bright orange.  If you see a bright orange wire, don't cut through it!

If it goes flat there is not much alternative. No can of petrol there!

So the photo is a battery pack towed behind a diesel van - it is still not very convenient is it ?

It  does not alter the fact that adding  a ‘mains out’ port on every electric car would allow the equivalent of a ‘jump start’ from anyone, and keep the time things are stuck in really dangerous places to a minimum - just getting enough charge in to go a km or two would be the difference between a lay-by or even a car park, and the middle of a dual carriage way.

I cannot see electrocution during DIY car repairs as a big thing - if you do serious car-repair at home then you may well be used to electric welding, disc cutting, jacks and compressed springs, the risk of crushing yourself under a gearbox…

The folk who wimp out at anything more than tyres or wiper replacements still will. Sure it is a new hazard, and the how to  do it safely will need to be spelt out, but it will not be long.

A small number of manufacturers are now fitting their cars with mains power sockets.  It sounds like a very useful thing to have, and not just for trickle charging someone else's car.

It's a grid lock with traffic in some areas at peak times and electric vehicles will not alleviate that problem. There are simply too many vehicles on the roads. Also residential areas, have escalating parking problems with vehicles being parked on pavements and other areas, causing a hazard. 

Entirely agree. It seems to me there's much wrong with just about every transport system we have - much of which seems to stem from being based on old technology - 200 years old in the case of rail and nearer 2000 year old in the case of roads. I wonder (just as a thought experiment) what we could come up with today if we could start from fresh using today's technology, materials and so on.

Quite interesting to read extracts from the various EV forums regarding the ability of the EV battery to be recharged when the vehicle has been left for some time in freezing conditions before attempting a recharge…..

It would appear that the EV prioritises the available mains power to warm up the batteries before they can be charged.

Also, there appears to be quite varied figures for range when driving in freezing conditions that are not attributable to having the “hot air heater” on but reduced battery capacity.

I have experienced failure of at least one lead acid battery due to letting it get discharged and leaving it that way. Could EV batteries be damaged permanently? I think that my next car may be EV, but not just yet!
