Cybertruck lead engineer Wes Morrill tweeted this ?

Cybertruck charge curve improvements are coming OTA later this quarter to unlock up to 154 miles recovered in 15 minutes.

Curves are important to me

Wonderful to hear they are adjusting for faster charging.

Yay! Hopefully, in time for my Moab road trip ?

If you stare at CT long enough, they appear like a magic eye.

looking at charging curves that I can find, and doing some rough math, this is 48% SOC. 0-48% SOC has been measured at 18m 11s. so it's a 16% improvement at the low end of the curve.

At first I wasn't impressed, but think about this logically for a minute. The charger is slammed to 250kW from 0-25%, and it tapers down from there. So they can't really make any miles/hr improvement in the first 25% of charge. So all of the gain must come from 26-48%. Which means higher SOC times are also going to be positively affected in theory.

Going by the one curve I'm looking at, the first 7m 40s will not change, and the 3m 11s of improvement must come from 7m 41s to 18m 11s. So for the 10m 30s of time it used to take from 26-48% charge, 3m 11s of that will come out, and it will now only take 7m 20s.


That's a 31% improvement from 26-48% SOC

Or, I'm wrong, and he means they are going to turn on 800V charging for all zero of the v4 chargers that exist right now

You are probably correct, there's not much more you can do when the current source is at 100%. All you can do is make the 100% last longer.

And yes, hopefully 800V is getting close and the 0-20% can get ramped up.

And that gets down to the basics, the faster you charge, the more heat you make, the more heat has to be discharged, or incur degradation to the battery.

And this should be a suggestion to folks, when road tripping, charge on the best side of the curve.
If you charge from 0 to 50% it takes less than half the time that it takes to go from 50% to 80%!
There's a lot to be said for charging to around 50% and then finding the next Supercharger about 150 miles away.

Lol. Nicely done!
