And that is the other issue - connecting a Leaf to a 100KW charger will not charge it 2.5 times faster. The cars have battery charging management that suits the battery pack and the conditioning of it. Those suggesting Tesla open their superchargers up to all may be missing that point - their EV will charge at the maximum rate their manufacturer has allowed.
If general public 60Kw or higher chargers become available each manufacturer will need to decide how much (if any) eaxtra juice they will allow your car to take - even for short periods. The vast majority will be unable to allow any more - the car/battery is designed on a knife edge already. They cannot afford to have even one customer actually kill a battery pack in 5-8 years. They need to balance a clear public demand with reality - but they are in for the long haul and make increnatal adjustments as costs fall and technology improves.
Chargers can deliver almost as much as you want. As long as the juice is around nearby. There is no point rolling out massive capacity chargers for the masses if none of the (mass produced) car batteries are able to use the full capacity.
As
@gangzoom says these are all run arounds at the moment and although some take the time to plan (and execute) long trips (
@Gordon @ Convergent AV and I’m sure I read an overheating battery issue in your excellent thread with multiple rapid charges? ) the fact is if that is your needs every day to jump in and go more than 100-150 miles total in the day without thinking about it, these are not quite ready to be the car for you.
