An actual OTA update! .... for DC charging stability

[anonymouse]

First time ever (apart from minor updates to maps), my J1.2 Taycan received an over-the-air update:
"This update improves stability during DC rapid-charging processes through optimised charging current monitoring".
During the update it says "WSQ7" update to "high-voltage converter" software.

I wonder what problem it fixes?

Assuming you didn't dream about porsche releasing an OTA update... the TI list will get updated sometime next week, and we will be able to see the new TIs with more details, including this one:

https://ti-list.azurewebsites.net/

Would assume some optimization on charging curve, best case scenario, worst case just some stability improvements.

In the PFF someone reported that the car indicated a max charging power (not plugged it) of 331 kW. Which is more than the claimed maximum of 320 kW.

My car has not received the update yet so I can't speak from my experience yet.

It’s just a small margin of error ; j1.1 is supposed to top at 270 but I have seen 290 also

I am taking the car in to fix problems with Porsche Connect, and they said WSQ7 was an open workshop for my VIN that I'll try and have them do at the same time. Actually, the problems with Porsche Connect are probably the reason *why* mine can't get this OTA if others have gotten it that way.

Interesting site : https://ti-list.azurewebsites.net, I don't yet see WSQ7 on there, but site hasn't been updated since February 6, so maybe its coming soon.

Who / What entity operates the https://ti-list.azurewebsites.net website?

The site automatically pulls faily from NTHSA.

Porsche releases TIs to NTHSA once a month, end of first week of the month usually.

So you will see the feburary TIs in early march.
