I agree, the 1 minute claim really glosses over the bigger picture. It
could become possible, though, if charge stations were composed of
battery banks which recharged over, say, 30 minutes. But, overall, you
could not service one vehicle every minute, continuously. Same as the
original problem.
On the other hand, a full charge won't be needed on a daily basis for
most cars. Those taking a freeway trip will need quick recharges,
perhaps. (But 5 minutes might be more reasonable.) Otherwise,
individuals might need to charge only once a week, assuming they can't
do it at home.
So, a 1 minute charge time might be supportable as long as there aren't
too many 1 minute charges in a row.

How many times have I read these words? Especially the "If it lives up
to
expectations" part.
An EV with a 200 mile range will need a battery of at least 40kWh
capacity.
Charging that battery to even 80% in 1 minute would require an
electrical
service with a capacity of roughly 2 GIGAwatts - and that's just for
one
car.
If you wanted to charge, say, just 5 cars at once, you'd need at least
10gW
of capacity. That's about 1.3% of the ENTIRE US capacity.
Where exactly is that kind of capacity going to come from?
I suspect this piece is little more than trolling for investors.
