What is your Taycan Range after X miles, Let's get some data

[B61]

The master mechanic at my local Porsche dealership did some research and could not find any way of measuring SoH using their service tools. He’s very conscientious and thorough, so I take his word.

That’s impossible.
I asked my dealer to measure SoH, they made it.
Afterall, they need to provide such services because of warranty.

btw: my ct4 was built in July 2021.
After 30k km, my SoH is 89%.

Do you use obd2 bluetooth dongle? You could cross-check the official 89% SOH with readings from diagnostic port, a point of recent discussion:

No, i don’t have OBD2 …yet.
Couldn’t decide which one to buy.

edit: since @WasserGKuehlt let me explain whay i don’t have obd2.
I’ve been looking several times @amazon, based on recommendations from this forum, but never finnished. There were so many different from €40-180 ….then I even read some customer reviews since I don’t like to buy something for 180 if there are options for 40….then I found out that some (cheaper) comes without software… until i realised that i actually don’t care/don’t need those measurements at all.

2021 Taycan Turbo here with 30K miles on it. I am seeing 280 miles normal at 100% and close to 300 miles in range mode.

@ciaranob Just an update regarding my SoH reading. I sent my car into the dealer and had them do an official read on it. It took them two days to do it. They first discharge the battery to <10% and then slow charge it to 90%, And then take a read with their PIWIS. The SoH they got was actually very close to what I got with my Vgate vLinker MC+OBD2. And they told me my degradation is within the normal wear limit. I also asked them what would happen if my battery degrade more than the warranty limit by 30K miles. They said most likely they will replace some of the battery cells that are faulty but most likely not replace the whole battery. As to how they know which cell is faulty, they could to give me an answer.

2021 Taycan 4s with 14k miles on it. I get 260 miles normal mode & 275 range mode at 100%.

These numbers are the same "summer" mileage values as when I bought the car 2 years ago, but they drop in the winter. I mostly charge at home and only to 85%, and perhaps that helps the battery SoH.

Excellent and matches the other 3rd party company’s result on another car i.e. within 1-2% of the OBDII tools we are using.

The PCM’s reading is not just a ‘dumb’ random output which would just make no sense at all. Long way to go to see how these disparate measures of SoH pan out but I do think they have merit.

BTW, the "new" SoH recorded by the Vgate OBD2 now with this "discharge to <10% and slow charge back up to 90%" is 86.36% vs. the 85.85% earlier. An improvement of 0.5%. Cell Voltage also improved from 3.78 to 3.8. So is that all due to "slow" charging? Or simply due to the OBD vs PIWIS?

Too early to tell - we'd need to see a more robust trend in future readings and TBH we're seeing +/- 1-2% from cars with consistent charging profiles between winter and summer amongst other variables. So could be in the noise but anything positive I'd take !

Any change in mileage with red new reading? - if you can provide that I can add this up-tick to the chart.

2021 TT (21” MissionE summer tires) with 34k miles still getting 250 miles normal range @100% and AC off - exclusively with DC fast charging (93.4 kWh battery) since Day 1.

I generally avoid depleting battery below 30% so even though I only use “fast chargers” use case condition is only 4-5 miles/minute (not the max throughput of +7-8 miles/minute).

@ciaranob , new mileage 13255mi, SoH 86.36%, and 258mi/100% with Normal Drive and Econ AC , Moderate Temp. City+Hwy driving.(Guessometer).

Cell voltage is not really relevant , but the spread of cell voltages across all cells is more interesting. Check and see max, min and average rates in the tool.

If you leave the tool plugged in when you drive you will see in testing graphics on cell voltage. First when you press the accelerator and again with recuperation from brakes etc. Cell voltage varies quite a lot then.

My understanding is that cell voltage can arguably be an indirect indicator of battery health - full range of these cells is from empty ~3.2V to full 4.2V, which of course will vary if looking at real time data. but in regards health you’re looking to see if they all balanced and all equally within 10mV of each other (from discussion in baseline thread).

Any pronounced anomalies might be indicative of bad or failing cells and just one can have a significant impact on a number of reported metrics.

@ciaranob , per your question, here is the new voltage range after the discharge and slow charge up. It actually show a higher range than when I checked earlier after all DC charging exclusively.
Max-Min of 0.017 (Now) vs. 0.012 (All DC)


Now

All DC

The absolute cell voltage values are just related of course to your current SoC so in that sense perhaps of minimal import but you can see just visually that all cells appear relatively balanced and without zooming the scale are probably close enough to the 10mV range variance (a few with slight larger variation).
