But you can bring fuel in a can then. When a 'letric cars stops, its really stopped.
Its a tow to a charger or expensive specialist help.
I suppose if you are really cheeky you could ask someone if you can plug in to their house for a while

True, but a tow to a charger is far from a problem, at least if you pay road assistance wich is standard on almost any car issurance, isn´t it?
There is also the time spent at the charger, providing it is free when you arrive. I mean it is not the same mental calculation as running low on petrol and knowing it will be an inconvenience if you run out. There is probably a similar calculation of 'how much of the trip is down hill' tooAndres125sx wrote: ↑Mon Dec 06, 2021 11:40 amTrue, but a tow to a charger is far from a problem, at least if you pay road assistance wich is standard on almost any car issurance, isn´t it?
Anycase this is the same as with first smartphones... A mobile whose battery can´t last two days? No way, my nokia battery only need to be charged once a week, I´m never going to use a smartphone...
In my almost 30 years of driving cars I only once ran out of diesel, and that was just being a fool. In fact, it was an old style diesel where you just couldn’t top it off and start again but had to prime and bleed the whole system.Big Tea wrote: ↑Mon Dec 06, 2021 2:17 pmThere is also the time spent at the charger, providing it is free when you arrive.

Buddy charging is also available with some cars - you can run a cable between them and top one up from the other. Of course that requires someone to be helpful which is probably less likely these days.
A simple battery pack of a few KG is probably also enough. The electric equivalent of a 5l petrol can.Big Tea wrote: ↑Mon Dec 06, 2021 3:17 pmI wonder on the drawbacks of a very small donkey motor driving a ( or the existing) generator that could add a small mileage or more over a reasonable time. Considering how light some portable generators are it would surely not be that big a penalty?
I just looked up a small Hyundai unit and it had a weight of 22lbs.
would that be a simple 600 Volt battery pack - or a simple 800 Volt battery pack ?
A simple battery with a transformer. You hook it up, provides 230 volts to charge the car for a few miles.Tommy Cookers wrote: ↑Mon Dec 06, 2021 3:46 pmwould that be a simple 600 Volt battery pack - or a simple 800 Volt battery pack ?
simply connected to the charging socket of the main battery pack ?
my original point was a wondering about the actual battery energy state when the system decides to shut down
(because the shutdown is driven by the battery life warranty not the battery energy state)
and .... towing isn't simple
I assume it would have to 'live' in the car to be worth while, so what would be the trade off a small genny (other than noise) which would be as flexible as required as long as fuel was available?Jolle wrote: ↑Mon Dec 06, 2021 3:58 pmA simple battery with a transformer.

These batteries are already available and I’ve used them quite often as a silent alternative instead of a generator.
I was more thinking as a service from charge stations, where you could pick up one, just like you do with petrol when you run out. Or, does everyone have 5 litres of petrol as a small bomb in the back of their car?Big Tea wrote: ↑Mon Dec 06, 2021 5:08 pmI assume it would have to 'live' in the car to be worth while, so what would be the trade off a small genny (other than noise) which would be as flexible as required as long as fuel was available?Jolle wrote: ↑Mon Dec 06, 2021 3:58 pmA simple battery with a transformer.

As a factory built-in unit the weight would be lower and could possibly be as convenient as a dash switch. I am not thinking something to rival a hybrid here, just something to help 'range anxiety' and not leave the fear of 'getting stuck somewhere remote'. Literally a last gasp aid
There could even be an opening for a 'call for a boost' service vanJolle wrote: ↑Mon Dec 06, 2021 5:14 pmI was more thinking as a service from charge stations, where you could pick up one, just like you do with petrol when you run out.

Basically, in essence, it’s not so different from petrol cars.Big Tea wrote: ↑Mon Dec 06, 2021 5:18 pmThere could even be an opening for a 'call for a boost' service vanJolle wrote: ↑Mon Dec 06, 2021 5:14 pmI was more thinking as a service from charge stations, where you could pick up one, just like you do with petrol when you run out.

FWIW here in Australia a lot of the car club service vehicles have a small generator now, for just such occasions.
Can you (in practical terms) recharge by towing?Billzilla wrote: ↑Mon Dec 06, 2021 9:17 pmFWIW here in Australia a lot of the car club service vehicles have a small generator now, for just such occasions.
And with a Tesla (at least) for every, say, 10 km you tow the car you get about 15 km more range thanks to the regen function. So not a lot of towing is needed.
