Thread: I’ve got a green oval stamped on my ass but I absolutely want one of these ...

There was an article in The Australian yesterday that China is considering banning Lion batteries in cars considering the number of fires. The plan is to replace them with liFePO4.
AFAIK LifePo4 are much heavier and less space efficient that Lion . To get the same range you would probably have to have no cabin or much reduced range.
It will never happen.

Battery technology is just going to get better and better.

I have Chinese LiFePo4 prismatic cells in my SWB Landy, 28kwh worth weighs 256kg , not as good energy density as Tesla cells but a lot more stable. I could just about double that without eating into any cargo or passenger space , but 28kwh gives me more than enough range for my daily driving. At the moment 24 cells take the space of where both fuel tanks were and there are 21 cells under the bonnet, 45 in all , each cell is 3.2 v x 200Ah giving 144v x200Ah = 28.8kwh.

Out of curiosity.

You lost 1 engine, fuel tanks etc.
Added 1 electric motor, control system and batteries.

What was the final variance in the weight equation?

Tesla model s is 100kw so about I tonne if lifepo4 using your weight as guide
Tesla
85kw pack weighs 540 kg.so 100kw about 630kg.

1 don’t know the volume difference but it will be a lot.
