kingdragonfly: I saw some comments that this would likely need hardware updates to existing cars, and obviously a faster charge means charging station infrastrucutre would need to handle higher currents.
The team makes some bold claims. The product allows users to charge a 60kWh EV battery pack with 119 miles of range in 5 minutes as compared to 15 miles in 5 minutes today. “The technology works with off-the-shelf lithium ion batteries and existing fast charge infrastructure by integrating via a patented self-contained adapter on a car charge port,” writes the team. They demonstrated their product at CES this year.
Most charging systems depend on fairly primitive systems for topping up batteries. Various factors — including temperature — can slow down or stop a charge. GBatteries manages this by setting a very specific charging model that “slows down” and “speeds up” the charge as necessary. This allows the charge to go much faster under the right conditions.
If only this were legit!
Unfortunately the laws of physics would suggest that these guys are pulling a con. To charge a 60kWh battery with 119 miles of range in 5 minutes while using an AI algorithm to speed up and slow down the charge is almost certainly nonsense. If we are talking about putting ~50% charge into a 60kWh battery in 5 minutes (119 miles of range would be somewhere around there) then that suggests that 30kWh would be added in 5 minutes, this would require an AVERAGE of 600kW of power to flow over those 5 minutes. If an AI Algorithm is slowing down and speeding up the charge current then the peak power would clearly need to be much more than 600kW.
So, how easily can we upgrade our 50kW chargers to over 600kW?
And how easily can current batteries handle 10C charge rates?
Certainly I've heard of the concept of pulse charging, which is supposed to allow higher charge rates without heating the batteries as much, but that doesn't mean you can increase the charge rate by such a drastic amount.

Tsk. Didn't you know that AI trumps physics?

Plus its from a startup in an accelerator, that has "come out of stealth"- pah, the laws of physics don't apply to Venture Capitalists... especially if they are about to go into a funding round....
but yeah, to dump 30Kwh into a battery in 5 minutes means a much higher peak power output than most current chargers are able to provide....
If I had a $1 for every new battery tech announcement I could afford one of the new Roadster's

Sounds like 100mpg magnetic fuel alignment devices and hydrogen injection for ICE.
Tesla are VERY clever in the way they make there cars all software locked.]
Doing this they can make money from cars they have already sold even if they never see that car again.
The biggest one we know of is autopilot can be added to a tesla years after its sold due to it having hardware already there.
Also since making this video Tesla will now software lock smaller battery pack sizes.
Tesla could also decide to charge for performance upgrades over the air they have been very clever and this in my mind is why there the most forward thinking car firm out there
kingdragonfly: Usually upbeat, this "Fully Charged" show is a bit of a rant
- new Ford's
- hybrid rant
- a Darwin Award for a stupid death
- confusing Tesla pricing

Dingbatt: the only things an EV can be attacked on, and that is charge times mid-journey. He says "just go and do something else", but the point is, you have to go and find something else to do while it's charging. Unless you want to stand beside it while it charges
This is an issue with my 24kWh Leaf, I do tend to sit in the car reading a book (on my smartphone) while it charges. But with newer EVs like the 64kWh Kona with a 400+ km range - you don't need to stop to charge at all on short or even medium length journeys. On long journeys, you would find that after driving for more than 300km you have no trouble finding "something else" to do while the car charges, you have been driving for long enough that your bladder is full and your stomach is empty for a start.

Exactly: this is a problem for early adopters like ourselves, but anyone who buys an EV in a couple of years will be getting 60kWh+ as standard.

Fixed that for you,
There will still be plenty of less than 60Kwh EVs being bought in countries like NZ that have an open market for importing second hand vehicles...
New Zealand’s strong government performance partly counteracts lack of scale domestic manufacturing, the country has opportunities in software agriculture.
