I think for my commute I would prefer a battery chemistry that needed slower charging, if it was cheaper or lasted longer or was safer, or lighter, or whatever. But I think there will always be use cases where it's worth maximizing uptime, like long-haul driving.
I wonder if trucking will evolve to do tractor swaps, where rigs coming into charge up will hand off trailers to fresh tractors. That way the cargo doesn't have to take up space in the charging lot or whatever. Or they might do battery swaps. I imagine for above some threshold of cost/minute downtime, the hardware for doing swaps will be worth the extra cost.
Nio has had battery hot swapping systems for years, but that's for progressive countries.
It infuriating how nice an actual non-fossil-fuel infrastructure could be, if only we had a government that would build it. The Nio battery swaps are cool, I want to convert one of my old tractors to a similar setup, except I'll probably just put a pallet of batteries on top of the engine compartment and forklift them on and off the tractor. But similar idea: let the batteries charge slowly on a rack while the tractor and implements only see a few minutes of downtime. But until we get our political shit together I'm stuck making my own with spit and baling wire.
In most jurisdictions, trucks are required by law to stop for the driver to rest every 5 hours or so. You can just charge the vehicle then.
But drivers swap on the road and don't stop.
oh yeah, duh. the vehicle's uptime is bound by its operator's.
