tCAN-PRO | Battery Statistics & Fleet Health

[ct14garage]

Well, today tCAN-Pro breached the 1000 scans mark, so I decided to publish a sneak peak of the LLM I have built and trained over the past few months on the data collected by all the scans from tCAN-Pro....

To be honest I'm surprised that the statistics look a little bit better than I expected, though they are still appalling enough.

95.4% of batteries are considered HEALTHY. and 91.2% of batteries are considered GRADE A (basically same as when it left the factory)

However a 2.1% of batteries are CRITICAL, and another 2.0% of batteries are somewhat DANGEROUS.

If this data sample scales somewhat to the worldwide Taycan fleet of about 150,000 units... There's a 2.1% of those cars on the road in CRITICAL condition (about 3,000 cars)

That also confirms my impression of the 51-page thread where we showed our batteries.
I'm still pleasantly surprised by actual data.
Thanks Cris, excellent work.

Fantastic information! Thanks so much!

Myth busted. Thanks Cris for all the work and info

Thanks for posting this, really appreciate it.

Would it be possible to get a breakdown of the model comparison between the healthy vs. not healthy categories? Specifically, I’m wondering whether having a Turbo/S versus a 4S/RWD makes any difference.

40 scans had bad (non green) results. I think 40 is too little to get conclusions without a big disclaimer. Any conclusion right now is speculation and will not help the community or other readers IMO. There is enough bad info about EVs already.

I’d be more curious on J1.1 vs J1.2. But I’m guessing the sample size of J1.2 is pretty small (and not old enough yet).

Makes no difference, battery is the same

Keep in mind also since ARB6/ARB7 got installed the car gets the error faster.
So we don't really know who had cells replaced or not.

That 2% does not mean there is 2% with failed batteries, it means there is over some period of time 2% of cars where battery was not fixed in the past and is about to fail.

Can this clarify this part?

For Taycan, ISO ≥ 1000 kΩ is generally OK. But below that it gets dangeorus FAST!.

Which ISO value? And, is it really one thousand kilo ohm? Aka 1 mega ohm?

For instance these were the readings from my car the other day.
IsoRes Batt+: 8.6Kohm
IsoRes Batt-: 1.6Kohm
IsoRes Sys+: 1.6Kohm
IsoRes Sys-: 1.7Kohm

This is cool. Any breakdown by model year available?

Battery is the same, but it’s more of a question as to if pulling more power (Turbo S) makes a difference to battery longevity.

From what I’ve heard, charge rate makes a bigger difference than discharge rate. Would be nice to see some real world data to back it up though.

You’re missing the point. It’s about identifying any correlation. What’s the trim split of the 2.1%. Is it 30% turbo , 20% turbo S, 40% 4S, 10% base etc

The amount of data points here is so low that you can not make any correlation.
Hell, extrapolating this data anywhere does not make sense either...

Is that true for pb and pb+? Is it just more pouches/cells?
