🔋 Baseline for HV Battery SoH Performance (Battery Degradation Data by Taycan Owners)

[Bognar67]

More than interesting...

Mine is decreasing consistently although the weather is warming up nicely.
Note: No DC, no below 10% or above 90% since reading 2.

READINGS:
1. 01.16.23 SoH 98% mi 6,875(reported and registered on the chart)
2. 02.05.23 SoH 97% mi 7,500
3. 02.25.23 SoH 96% mi 8,472
4. 04.27.23 SoH 95% mi 10,003
5. 05.21.23 SoH 94% mi 10,852

1) Delivery Soh - unknown
2) Current SoH - 99.19%
3) Current mileage - 1560
4) kWh DC charging -minimal, whatever they did at the dealership before I picked it up
5) Build date -July 2022

Current SoH - 96.77%
Current Mileage - 6108
4-6 DCFC sessions.
~5 charges to 100% for trips.
30-85% is my typical SoC at any given time.

Will update charts/spreadsheet on return early June - thx for sharing and indeed mine too has not seen any reset/bump, only a reduction.

Picked up a 2022 CPO with the Performance Battery (small battery) last month. Here is my current state:

1) Don't know
2) 92.33%
3) 16,760 miles
4) Don't know
5) Build date December 2021

All updates added to the chart - I will clean the chart up when I get home as getting too busy - also clearly the moderate climate trend lines need updating!

32.000km.
Still always charging to 100% @11kW.
No fast charging.

 

[Hatten]

1) N/A
2) 99,57%
3) 1040 km
4) zero DC charing, only AC at home.
5) 2023 feb

How often do people check this data or do you leave the dongle connected all the time?

I let about 5K miles pass by between checking this number.

Once a year.
You can leave the dongle in, it only activates when you start the app (Bluetooth).

Haven't lost much the last 10.000 km. ?
I'm (very) curious about the next 10.000 km...

Some are providing more frequent numbers I.e. say every 2K miles or so whilst others out to 5K+. The SoH varies quite a bit so I’d prefer more frequent updates in years 1-3 to map that out.

2) 97.8%
3) 2400 miles
4) charged at home except 4 times.
5) car built April and June 2022 then in storage without 12V battery until I picked it up on 1st December 2022

1) no idea
2)95%
3)can only find the most recent month listed in the app and it's actually missing 3 charging sessions, but May is most of the DC charging except for some test sessions to try different charging vendors. Reasonable guesstimates for the missing 3 sessions and around 350 kWh of DC charging lifetime.
4)left production on 12-22-22
5)only to 100% once. 282 mile range displayed. Never below 15%.

No idea how many times it might have been brought up in this rather long thread but my readings seem to support rs38's assertion of SoH being based on 86.7 kWh (post #38). Car Scanner shows available battery energy at 48.2 kWh, "SoC Display" @ 58.53% so total, in theory, at 100% would be 82.35 kWh. With SoH at 95% the calculation seems to be based on 86.7 kWh. Using "SoC HR" (58.82%) results in a slightly lower "starting capacity" of 86.3, but that's easily a rounding difference.

Picked up the car in February 2023 and it's lived in Florida/moderately warm temps since.

Thx will load asap - and agreed re SoH measure - I also mention it as based on usable battery in my original first post.
