“The new cell that [Molicel is] coming out with, the X series, boy, they’re claiming they can charge that from zero to 100% in 90 seconds,”

That's great but how do we push all that energy into the battery at home in just 90 seconds? OK, we can push it in maybe 9 hours at home and still be happy so another question: what kind of equipment would back a charging station on a highway to make it able to charge a few of those batteries at the same time?

I think at that point you basically need to use one of these batteries as a buffer to charge it, and you're still gonna need one hell of a cable (already the really fast-charger cables are water cooled because the water cooling adds less weight than the copper you'd need to avoid the active cooling)

> how do we push all that energy into the battery at home in just 90 seconds?

If they are talking about an individual cell with a nominal voltage of 3.7V, then "any" modern fast charger will do.

I don't think they were talking about a full-blown EV power bank.

You don't have to, it makes it a lot easier that you can do it.

You can also charge supercapacitors and uncharge it very fast if you like.

You can use the whole capacity of a charging park for just one car (if not a lot of cars are there).

You could also do a more classical gas station setup instead of a charging park. Cooled cable, 1-2 proper ports on the bottom etc.
