always said this

with a battery someone else has misused, swapped with the new battery that came with your brand new car! It's much like putting diesel into your petrol car.

could say that about gas bottles

anyway the battery would be on hire

Surely the batteries would be tested etc and the duff ones taken out of the system. The options for people to abuse a battery would be limited. You?d have a particular battery until it needed charging, then replace it. Even if you charged it at home, the chargers are ?smart? - you can?t really abuse the batteries.

Certainly the current (no pun intended) system which takes even 20 mins per ( partial) charge / top up is unworkable. We considered a Tesla 4x4 but dismissed it due to the range / changing problem. Hybrids offer a better solution.

they wouldn't need to be charged at home

Didn't realise you were a communist. Wanted every maker world wide to follow your rules.

Well all manufacturers of petrol and diesel cars manage to produce cars that run on the grades of petrol and diesel available in the target market and also manage to fit the correct sized (and often coloured) fillers. They all (on the whole) managed to standardise on 12V electrics, negative earth, fitting indicators required by the target market, etc.

But the batteries would self-monitor and any that fell below a certain standard would be withdrawn from use - the cost of replacement of failed batteries would be spread across all owners, not fall (possibly unaffordably) on one unlucky person.

Doable for motorbikes/scooters perhaps, utterly impractical for cars. It was actually Elon?s plan originally but fixed battery packs and rapid charging was a better/more economic/more practical solution.

Charging at home is FAR cheaper, especially using economy 7. I send almost nothing on petrol for local trips and charge overnight. Even without charging the car, economy 7 was worth it, with charging it is fantastic - even since recent price increases in electricity. I never charge away from home unless it is free- some shops have free chargers.

For that matter, it was the principle on which stage-coaches worked.

Could perhaps be more practicable for commercial vehicles though. It always struck me that the space under the load bed of both rigid and articulated lorries was a useful size.

cheapskate

much better system

either that or the private car ia so last century...take your pick look at the mess all the defferent plugs and systems has got us intp...

they did

would work with a better battery...not before

But they don't all have the same size of fuel tank, engine size and and miles per litre figures. The same size of battery wouldn't be fitted in both a small 2 seat city run-around and a Chelsea tractor.

wummin driving chelsea tractors would be banned
