Typical EV 80 kWh battery, from 0 to 100%, in 5 minutes …
… requires a 960kW charger. And it has to run at 960kW sustained for the entire 5 minutes.
The only chargers than can come close to 960kW are the ones that are used to charge the Tesla Semi trucks. And there are VERY few of those types of chargers right now.

Well, that’s huge, indeed… I could get past the paywalls to dig deeper than the article itself, but if a new tech, more power to 'em! pun intended!

Hi @MarkR,
Imagine what might happen to the grid if a few dozen cars came in started charging in one locale on a hot sunny day.
Nothing notable would happen. 960kW x 50 cars is still not meaningful to the grid in any location that would have a 50 charger facility. There’s already a large supercharger in CA that has about 100 spots, each at 250kW, in Coalinga, CA. And they are building another one like that in Barstow, CA (and this one may even support 400kW charging for certain non-Tesla models).

Even if the sudden load on the grid was a problem, the supercharger location could have a built-in limiter to ramp up the current for each charger over some short time period. I think they actually already have this logic in the car and/or within the EVSE because after you plug in you see the amperage on the display increment up to its set point over 4 or 5 seconds.
