Haven’t gotten 275kw charging lately and just got this on an sf to la run. Brand new chargers at Harris ranch.

Wonder if that's the car reducing charging power because of some issue, or if that's just the car reporting that the EVSE isn't delivering enough power...? What were you actually getting?

130 at a 350. 4th time it’s happened but first time I saw the message. Others on the board havehad similar issues.

Coincidentally, yesterday I rewatched the Out of Spec Taycan cannonball run, and one of the problems they encountered was that when the battery was fully preheated, the interplay between the Taycan and some of the EA 350 chargers resulted in the session failing within the first minute. It seemed that the EA Charger balked when the Taycan jumped right into maximum draw. I wonder if this message is an indication of some mitigation for this problem (whether on the Taycan side or EA side) to this problem?
It would be interesting to hear what battery temperatures are when folks see this warning.

Some earlier (inconclusive) discussion of the same message here back in July.

I charged at 7 350kw stations this weekend and got not a single one over 140.
Is this EA or Porsche?

I keep seeing 130kw as the max speed in so many different posts in this thread and all from US owners. I also have not seen any thing more than 130kw either. This is probably not random.
I hope EA is not capping our free session...

130 On a 150 kw or 350 kw unit?

Make sure that you didn't have the optemizing battery friendly box checked in

You don't have the "Battery-saving fast charging" option enabled under Charging ( ... ) in PCM which forces battery protection when using ultra fast chargers?

Asked and answered just above. Also that would be at 200kw

Yeah saw that as I'd posted. I thought it throttled back to 125kW.
