I have similar difficulty seeing how they will get internal resistance down low enough to prevent a large rise in temps, I pointed to that in a previous post but they can side step a bit.You'd probably also need some inventive cooling to keep the battery from catching ablaze during charging.
I'm wondering where the disclaimer is..
*Requires a 480 volt circuit
Folks they said capable of not that the infrastructure would support doing it . Pigs could be capable of flying...if they had wings!
Prepping a good ol' Pump-N-Dump.
I call utter BS on this.
For a 500 mile range they'd probably need ~150 kWh battery.
Considering real world charging efficiencies of ~85%, they'd need to apply ~175 kWh in a minute.
That would require power delivery of ~10.5 megawatts for the duration of that minute.
That would be like having your own small power plant for a minute, not to mention there not being any power interface capable of handling that.
Assuming a power factor of 1 (this never happens, but lets just assume) you'd need:
- 87,500A at 120V; or
- 50,480A at 208V; or
- 43,750A at 240V... etc.
Let me point out here that the highest power NEMA connector (us power plug standard) is 50A at 240v. This is one 875th of the required power.
You are probably right, that they are referring to something like this, but this would be disingenuous. This is not "charging". This is "replacing".
This is some sort of scam and/or wishful thinking.
And even if that is how it is done you don't want people messing with 1000s of volts circuits as at that level if it shorts its a bomb and blows you apartThis is what I was going to post. It's either only capable of charging that fast in theory, or they're using some super-capacitor array that charges like normal over a 4-8hr period and then dumps it all to the car battery when plugged in.

That is not trueAll VFD's output DC
I've read some non-related articles on new battery chemistry and charging technologies coming down the pike, so it's definitely possible. How soon though? That's the question.
does that term still apply to a stock that isn't sold on the open market? Maybe they are trying to attract private equity but question still stands.Pretty much this.
That being said, this sounds like a pump-n-dump to me.
My take on it is you can recharge on the road fast but 1 minute is daft.So they have a 160kWh battery. That can be charged in 1 minute. As in 60 seconds. Meaning you have to charge it at 50kA from 220V?
