Does that mean it takes 500 amps to charge a 50AH battery in 6 minutes?

@eric yes

My calculations on another 32kWh, 5 minute charge battery gave me the number of over 2700 Amp at 440V. I don't think the average human can handle a 3m section of a charge cable of the cross sectional area needed to handle that size of cable if of copper.
The infrastructure to handle that sort of charging will be impressive also. These ideas, like the Hydrogen fuel cell come about half baked with a good dose of ignorance/fantasy heaped on top.

I will believe it when I see it. What voltages are they using? Charging that many amps so quickly means they have a new definition of safety. The power service to my home wouldn't even begin to handle that.

Recharging points will need some way of storing power that can be dumped into batteries quickly. Perhaps flywheel power storage.

Not sure to have understood : is it really three times the range, or three times fast charging ?

It sounds like everyone is a step ahead of Dr. Osamu Hori.

Why doesn't an oil company, like Shell, collaborate with an auto manufacturer to produce a car with slide-out batteries, then store fully charged batteries in each of their service stations. You would drive in, a robotic arm on one side of the vehicle would slide in the new batteries, pushing the spent ones out the other side of the car where another robotic arm would catch them and take them to a charging station and into the queue to be used for future customers. At the end of the month, Shell or whoever would bill you for the number of times you exchanged your batteries. The whole process of "refueling" should take no longer that filling up with petroleum.

I was intrigued by the "ultra-rapid charging" in six minutes. I would be impressed by the plug that would not melt during that. Liquid cooled, perhaps? And what about the charger itself?
Laws of physics, stand aside!

if three times the range of current 300+ mile EVs like the Tesla model S and model 3 (upgrade) then you would have 900+ mile ranges and no need to charge on the Interstates EVER again. You simply would have a days full charge from your home charger, then charge full at your destination, then again when home.
The world is changing and if ICE lovers don't get on board their going to get stuck with a lot of pricey inventory they can't get rid of!
No thanks I'll stick to EVs for the rest of my life (2 now; 3rd when a pickup is offered).
3 times the range would give pickup trucks the towing capacity needed to make them practical--we already know they can outtow a diesel an EV pickup truck can easily be made to tow 50,000 lbs--far more than the most ever by a diesel (around 35,000).
That's why trains use electric motors to power their huge hauling loads with diesel providing the electricity to the motors.
Electric will propel 100% of all transportation within 25 years. Jets too.
