You suggested it when and to whom? They? Core exchange damage. Care to expound? Your sensor sugar-plum image can mutate beyond your wildest cowpoke dreams. We don’t see any of these parameters insurmountable, if it’s ok to use that term around the more libidinal type cowboys.
I go to a lot of trade shows, including the ones that showcased the EVs, and suggesting modular battery packs for rapid exchange instead of slow recharge was the first thing I suggested.
It is what I wanted, in order to make EVs more appealing to me, since I would not like waiting for recharge.
And they all said it was never going to happen, (modular batteries).
That is because if people do not own the batteries, they are going to abuse them, by over discharging them, charging them too rapidly, letting the temperature vary, etc., so then the batteries would very quickly go bad.
And then the recharge station that thought it was going to make $10 profit on a recharge, instead takes a $9,990 loss on a battery they will have to replace.
And by the way, they also explained that battery exchange takes about 5 hours, as they are integrated in a cooling system, either water, oil, or air.
