V4 Supercharger 14% to 56% Test - 15 minutes!(10:45 - 11:00)
V4 Supercharger 14% to 80% Test - 33 minutes! (10:45 - 11:18) Down at least 12 minutes, from 45 minutes on V3 chargers.

Is there a way to know which charger is v4 from your Tesla app when using the route planner?

It says 325kW when you select it.
Unfortunately, the filter currently includes 150kW and 250kW sites.
Here's a post with most of them:

I know there was talk that v3 superchargers will be able to support 350kW. If that can turn that on next, that would be amazing since there are already so many v3 chargers out there.

It nice to know I could charge fast for long trip, but I sure don't want to charge like this every times since I use supercharging frequently. I prefer the slowest one (72kWh Supercharger), for the long life of my battery. I am planning to keep my CT long as I live.

V4 Superchargers are the new posts with V3 cabinets. The cabinets can do 325+kW, but Im pretty sure V2/V3 posts lack the current and voltage ratings to go much above 250kW.

It's not true that fast charging is bad for your battery. The battery management system does a very good job of making sure fast charging doesn't cause degradation. Jeff Dahn, who knows the batteries better than anyone stated this. Degradation is main due to characteristics of the battery and for the panasonic batteries there is a tiny bit of degradation every time you charge past ~75%, regardless if your slow charging or fast charging.. We don't know if the 4680 batteries have this some characteristic or not. Regardless, fast charging does not cause degradation.

hmm, so in theory could the just replace the v3 posts with v4 posts?

At some sites, that's what they have done.

Another data point.

In relative terms this isn’t really that fast. There seems to be some thermal limit they’re hitting either in the pack or the charging unit.

I can usually get around 80 kWh in 30 min in the charge curve sweet spot with 400 V charging a Rivian so these V4 numbers are not even close to what 800 V is capable of. If they can avg 200 kWh from 10-80 that’s about 25 min for ~84 kWh and we’re not seeing those numbers.

Woohoo! MaxHit Full 325 kW!!!!!

Sounds like OOS will be releasing a video soon, but early data suggests this is about 5-6 minutes faster than the gen 1 large pack, and an additional minute or two faster than the gen 2 pack.

Depends on what you mean by thermals though. To get 325kW they are hitting 875 amps and that seems like the practical limit of some piece of equipment in the system. Could be V3 cabinets/bus bars, could be V4 cables (though that seems unlikely), could be port to battery cabling... the cell temps so far don't suggest they are overheating, but could be any of the prior pieces.

325kW at 22% would be the highest percentage it has held that rate yet. What percentage did you plug in at?

cant wait for 500 kwh
