Thats just getting the charging network sorted as I can already charge my EV from 20 to 80% (or about 47kwh) in about 18 minutes at the right charger and faster charging EVs are already coming. My car doesn’t even have battery pre conditioning that would improve things further.
Charging to 100% on stops on a road trip is always a bad idea, you are always going to need A LOT longer to get that last 20% or so than the 60% of charge from 20 to 80% due to the way current batteries work.
It is almost always quicker on an ultra fast charger to charge twice to 80% than once to 100% and you get significantly more range doing so. Charging twice to 80% nets me 94kwh and charging once to 100% from 20% nets me 61.6kwh, and the former is usually minutes faster to do as well.
