Lithium cells have a theoretical energy desnity of 350Wh per kg...and
already up to half that or more has been achieved.
So 3kg per kWh, or 300kg for a 100kWh battery. I think that's wiped out any
weight saving from removing the engine & gearbox from most small cars. That's
assuming development to the full potential, at present it's going to be a
600kg battery.
I agree. Its no better.
But its NO WORSE either.
The actual weight of an IC power trains is massive.
In the electric, its only the batery that really weighs
