Can you share the other requested info that goes with you
What is the difference between those two SOH indicator? I believe the one I need is the 91.76% but what is the other one?

Can you share the other requested info on your car that goes with your posted SoH so that we can add this to the chart? I don’t believe you shared prev correct?
Thx, C.

there was a bug in a certain version of carscanner, mixing SoH and and SoC.
Update the app, add a new car, select Porsche Taycan connection profile and reset dashboard setting to default (<- important).
Also enjoy the many more pages the dashboard provides including the very nice 198 cell volltages at one glance screen.

Laurent - wanted to confirm - I'm guessing your car's build date was probably Oct 2021 and not Oct 2022 as stated, correct? Assume model year was a 2022 like mine?

And surely your SoH is 91.76 i.e. the other reading being possibly your 12v battery or are you now sure the BMS reading is your car's HV battery SoH?

yes, it is a 10/21. correct.

Unfortunately, it read HV Battery State of Health = 86.36. Before I charged it to 100% it was 85.2 %.
This is a bit alarming.

Oh, interesting - that does appear to be quite low - I’ll update the chart tomorrow. Does make me a little concerned re hot climate stress on out batteries!
At least if that trend continues and yours hits sub-80% you warranty will easily cover this (need to recheck mind you but I believe that’s the no. the 8 year warranty says it should not go below in this timeframe)

Corrected the input in the chart/table - you do now have the lowest reading to date of all 29 cars regardless of mileage, age etc!

Bear in mind we're talking 1.5-3% less than the other cars in your mileage range from warm climates but to me that is still somewhat significant. Its a small (and statistically non-significant) group, but your data appear more in line with the Turbo/S models whose lower SoH may be related due to other battery issues.

It would be good to get another reading from you perhaps in a week or so or with some more miles and see if this low SoH data is consistent - it certainly seems anomalous relative to the other data we have in this table to date.

New reading after a 100% charge and read 87.5 for soh.

Loaner 4S: 35000km, MJ20, 94,8% SoH...never expected that
Wow! Maybe that Porsche marketing no. not alone :)!

Will get these last 2 updates loaded when home later today.

First of all thank you @ciaranob for data collection and organization.

I just received my OBD tool (vLinker MC+) and -as an OBD rookie- would like to know if it is necessary to charge 100% for accurate reading or 80-85% is good enough?

Your current SoC should not be a factor but others may provide more insight - and in regards consistency with what we have to date, folk who have provided their SoH data to date have more often than not taken their readings w/o ref to current SoC. So please share and we'll add to the list :)
