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

[ciaranob]

Interesting information, but TeslaBjorn already has done a lot of similar tests, and his test compared yo this companies was not far off either. He also tested this tool earlier and gave his comments. And I have a lot of respect for TeslaBjorn and his tests

Wht I find much more interesting though is his comment about the Porsche service having done a test and been ble to give him detailed information. According to @Archimedes in a post, his valued service guy was not able to provide such info Via their tools???

I guess from my perspective the point here for me was that for all the negative comments about the 'flash' SoH reading we get fro the OBDII tools (and with ALL the provisos as to what we are actually measuring etc aside) the difference between a deep 5 day SoH test and the flash reading was in the end 2%!

In the Baseline SoH thread we've repeatedly stated that these OBDII readings basically are by default +/-1% and with some clear examples of varying to 2%. What we don't have to my knowledge is a comparable measure of error/std deviation for that companies deep testing (nor for that matter from Porsche's own deep testing - correct?).

So again, irrespective of statistical robustness, the general trends we're seeing from the OBDII data on this forum are likely not massively off (imo) and as I said before, at some point we can possibly derive a value to bulk shift to be inline with more robust deep tests but suspect we'll likely never get access to enough of that data - hence why the OBDII data are somewhat useful again as a substitute.

PS: I've listened to a lot of Bjorn's monologues too , but I don't recall getting a lot of actual hard data from him (could be that I've simply missed this and please advise) - lots of comments and speculation/observations, much of which is indeed very useful but usually defers to other's reports like those I've posted on the baseline tread for actual data.

1) Delivery Soh: unknown
2) Current SoH: 92.6
3) Current mileage: 19300 miles
4) roughly 2/3 fast charging at 250kWh, 1/3 at 22kWh . Mostly up to 80%, unless for some long legs/trips where i would go to 95%/100%
5) Build date : delivery 07.2022

Climate Zone = Cool
Model = 2022 RWD Taycan ST with PB+

Most appreciated - your data added to updated chart in Post #1

I haven’t noticed this thread before at all, so here we go:
1. Unknown
2. 89,1%
3. 29.795 km
4. Never on fast charger. Mostly 22kw at work, up to 100% (about 85-88% when garraged at home); two or three times below 20%, once down to 6%.
5. Build date: July 2021, delivery September 2021.

climate zone: northern than 45, but i’d still say “warm”.
Model: CT4, MY21

Hmm - I already have you in there - but maybe I granbbed your data from when your other posts/different thread of the same info - either way def in chart - I also added that very high mileage car you mentioned too albeit 'second hand' info !

Here is a further update for you.

MY20
52142 km
89.41% SoH.

my car has kept its SoH from the first measurement at 28646 km to 52142 km at 90%!
And that is with about 80% HPC charging on long road trips during that period.
Since I mainly drive along main motorways on these trips with speeds of 110 to 150 km/h, I think things are holding up very well.

I have an average consumption of around 22.0 kWh/100 km or about 2.9 mi/kWh.

My average read out of the total range at 100% SOC is around 370 to 380 km. Feels like I also have got a reduction in range by about 10%. But overall range coupled with the density of Ionity, Fastned, EnBW, Aral Pulse chargers along the routes, there is no issue whatsoever. Very pleased with my use case for long trips. Quick, silent and comfortable!

Very nice to hear.

My SoH keeps dropping just by looking at it. Fair enough that I only have 4000km but each charge seems to kill 0.1% of it lol. I really hope it stabilises eventually

Yes it would be interesting to know if the BMS releases some of the hidden capacity at certain stages?? I wish we could read the total battery capacity somehow.

In the CarScanner app my battery capacity was reported at 78 kWh at 100%, what ever that measurement is??

Excellent thx - chart updated and added a comment to your specific trend as you might be the first example we are seeing of a flattening out of your SoH trend - speculative at this stage of course!

Curious to know what your usage and charging patterns are like.

@lcarron

My car is following the exact trend he is on so suspect his not that dramatically different in respect use - I def need to go through some 100% down to sub-20% charge cycles along with preferably some more decent road trips lengths to see if mine recovers/stablizes in any way from its current trend!

The upper connected red curve my car (after only 7250 miles and 1.5 years of use!) and Icarron's car the line with two control pts and 20,000 miles, also in red for Hot climate.

Despite all the skepticism re SoH measurement (not going there again ), these albeit potentially slightly negative OBDII data are holding their (climate zone) trends very well (54 cars and 83 readings to date).

We currently have data from 11 US States (covering all 4 zones and only country to date with Hot climate data but only 5 cars) and globally data from 12 additional countries from Turkey to Finland (mostly EU).

Your car holds highest values for the Hot trend so you might be the luckier anomaly
