“Google-backed EV charging startup Gravity opens fastest public chargers in the US”

500 kw rate in a suitcase-sized charger!

Gravity says its 500kW EV chargers, which are about the size of a carry-on suitcase, can deliver up to 2,400 miles of range in a single hour or up to 200 miles in five minutes. While those charger speeds are the fastest in the US, most EVs can’t come close to reaching a 500kW rate while charging.

""Beginning today, fleet and commercial operators and EV owners can visit the Gravity Charging Center and test the technology for themselves. The Gravity Charging Center is located at 401-471 West 42nd Street, New York, NY, 10036. If you’re in the area, visit them and report back!"

So, any Rivian owners in the area?

Interesting. I’m wondering if there’s a consensus as to the point that’s “fast enough.” My understanding is that the faster you push energy into the battery, the faster it wears. Is there data that suggests “slower DC fast chargers” could be better long term than faster fast chargers?

Maybe faster is better until fast charging only takes, say 5 minutes to add 200+ miles. Someone on this forum must have thought this out already…..

The only question that matters is whether they checked with big mouth Tesla Cybertruck engineer to get his Twitter approval for the location and length of the cable.

That's gonna be pretty hard to navigate with a trailer.

10 minutes per 3 hours of driving without needing to slow down, in the winter time, is what I consider the "holy grail" charging speed. Based on my experience with how inefficient the R1T is under those conditions, it's around 1 MW, and would require a much larger battery.

This will be awesome for the ID.4 owner I met at a charger recently. He pulled in at 96% SOC to 'top up' and was upset he didn't get 350 kW as advertised. Now he'll be able to charge for an hour and get 2400 miles of range (per the article). /s

Did you educate them? Or was it just too hard to know where to begin?

There, fixed that for you.

Yes, I tried to. Spent about 10 minutes with the guy. I mentioned the max speed of the ID.4, I thought it was 150 kW, couldn't remember, but knew it wasn't 350 kW. I also talked about the SOC playing a big role here. He didn't seem very convinced and more annoyed at VW and the FPL Evolution charger. He said he tried EA also and got the same results. Hopefully, someone else will convey the same info to him at another stop to reinforce what I said. Education is hard.

I wonder what Gravity is charging per kWh. DCFC has gotten very expensive lately imo.

That's actually not exactly true. Batteries dislike being hot and they especially dislike being hot and full. So DC fast charging is only a problem if you can't control thermals during the session. Cooling becomes more challenging as the battery gets full, as it's resistance is increasing.

But the idea that fast charging = degredation isn't really accurate.

I'll be in the area for NY auto show in a week or two, will check it out and report back!

I feel really bad for someone who thinks they need to top up from 96%. That’s some type of anxiety I’m very glad to not have.

RIP this guy's battery.....
