[Field Marshal Dr. Opti]

Watched this yesterday with Jason Plato and Vicky Butler Henderson......

They were reviewing a Chinese manufactured electric car called a Neo. The clever bit is that it could go from having a flat battery to 100% fully charged battery in less than 5 minutes.

How do they achieve this?

Simple. They change the flat battery for a fully charged one. Is this the future for 'leccy cars' rather than plugging them in for hours on end?

[Andy B]

the trouble with that is that 'the battery' is built up out of loads of smaller cells connected together which would mean all the car manufactures would have to build their cars around standard sized battery packs. And, the 'new' battery that goes into your car could be fubar'd .... I see it all the time with our fork truck batteries, you put a new fully charged battery on, drive 100yrds & it goes from 100% to 70% ..... the batteries are all knackered it's just that some are less knackered than others.

As Andy B says, standardisation is the key. Just think how difficult it is with AA, AAA, C, D, PP3, PP9s at the moment, and that's before you get into button cells/watch batteries.

Until/unless everyone used the same battery pack, then you risk turning up in the middle of nowhere for a battery swap and the garage haven't got your 'type' in stock. Presumably they'd remove your battery, charge it, and put your battery back in, which won't be 5 minutes.

You've also got the problem that a small city car might have a 33KW battery, whereas a luxury long distance car has a 100KW battery, so even once standardised, they would need to be made up of (say) multiple 25KW or 33KW sub assemblies.

[Field Marshal Dr. Opti]

Thanks, chaps.

It looked impressive in isolation.

The floor open up and the old battery is unbolted without the aid of human beings. The new battery is then bolted in place by machine and off the car goes. Less than 5 minutes.

Which is why I would be concerned about buying a 4 year old  and over electric car.

I imagine the prohibitive cost of a new battery could effectively mean the car goes to be cubed.

ICE batteries are largely standardised...

Are you sure it wasn't called the Effluence?

They are a lot smaller a 100KwH battery pack.....

[Doctor Gollum]

True, but it's not an alien concept

                 Or maybe flatulence?

They are doomed to fail there will never be enough of a reserve to charge the infernal machines

I have a lefty/greenie mate who often enthuses about electric cars and the utopian days ahead when we are all trundling around in little milk floats, but when I point out inconvenient truths like Where is all the electricity going to come from? He gets mad and dismisses me as An effing denier! 

He's good sport!

Ahh, yes, virtue signallers don't like seeing the inconvenient "big picture".

If everyone plugs in their milk floats at 6PM ready for the following day will the grid cope?
