Anyone tried V3 superchargers yet? There is one that I will be driving through next week, but the highest charging I have seen is about 120kw on a 150kw supercharger.

Yeah, i saw a video on youtube, but don't think the battery was that low. Remember, it will need to be at about 10% of battery for it to get 250kw charging.Anyone tried V3 superchargers yet?

There are very few V3 superchargers in the world right now. Its more of a concept for the future, even though the technology is complete.
Having 1 V3 supercharger on a long journey with many stops doesn't make much difference at all.
There is a V3 supercharger station just built in Darien, CT, maybe not too far from you if in southern NY.

I just stopped at the fishkill one at 40%...didnt go above 130kw.
Oh wow didn't realize high rates are only available for a very small part of the battery range. I guess you really have to push the battery to below 10% on road trips if you really want to take advantage of V3 charges.Under rare ideal conditions, starting at 40% could see over 180 kW. I would not expect this kind of charge rate during temperate weather even if the car preconditions. The batteries are very sensitive to heat and have to be above 40 deg C to get close to these rates. Highway driving and preconditioning are very often not sufficient to heat the battery to allow ideal rates.
Be careful and realize that the time savings between charging at 150 or 200 or 250 kW isn't a whole lot. If it gives you range anxiety to drive it below 10% then I'd submit that it's not worth it.Oh wow didn't realize high rates are only available for a very small part of the battery range.

Here’s the long thread we used to collect the Model 3 data.Is there an app I can use to graph a charge profile? I can drain the battery and go to the local V3 supercharger and check what the profile looks like in for below 60% SOC
...The battery needs to be hot. The pre-conditioning done when a Supercharger is selected in the nav helps but it rarely gets the battery to optimum temperature. Flogging the car for a while does help. Battery heat is generated as a squared function of output power. So really high discharge or regen rates are needed. Acceleration can pull 100’s of kW from the battery and regen maxes at about 80kW, IIRC, maybe a little more. As a reference, highway cruising only needs about 25-30kW and produces MUCH less excess heat...
*IF* Bjorn’s Model 3 is nerfed it’s because he has Supercharged over 9 MWh into the car. Heating the battery via rapid discharge is certainly not great for the battery but it’s not any different than a lap or two at a track.
However, there’s a chance it’s true. The coolant system is obviously different between the cars. The Octovalve and heat pump have replaced the Superbottle. Sandy Munro also commented that the Y radiator is “quite a bit bigger” than in the 3. (Model Y E20 @ 8:30) If the Y coolant system has a higher capacity to cool the battery, the Model Y charging profiles could be more aggressive than the 3 and allow higher charge power at higher SOC.
Bjorn's M3 has already been nerfed due to doing these things.
Charged from 1% to 100% at the Anaheim V3 Supercharger. Peak was 250KW and 1,014 miles per hour. Charging added 75KW to my performance Model Y. Hope this helps.
