superfast charging in just 10 minutes; is that true? Very cool if it is.[/QUOTE]
I honestly don't see how they can charge it that fast either. The batteries are 44 kW. That means you have to provide that much power in 10 minutes.
To put in perspective, the US, residential are usually 240 V, and up to 200 A. You would need the power from 5.5 houses (full- assuming no losses and nothing else is plugged in) just to charge it in 10 minutes.
Just from a safety standpoint, I would be very hesitant of messing with something that pulls more power than 5 combined houses.
The only thing that I can think of is using a 600 V. I've dealt with 600 V @ 315 Amps a few times (that's not even enough to charge it that fast), and that's insane voltage and amps.
