Team,
from history and posting this comes up a lot. How long will my Taycan battery last?
The honest answer is: No one really knows - but a lot of people have a pretty good idea.
from this posting - https://www.taycanforum.com/forum/threads/another-charging-question.10726/#post-155263 - I'm sharing a summary of my personal conclusions.
we can however make some SWAG's at what the underlying limits of the Taycan battery are based on Porsche's warranty limits and making well reasoned inference that Porsche's warranty limits are "conservative" - i.e. I would believe the hope that in the common case the battery will easily exceed the warranty claims by some significant margin - the exact magnitude of this margin is likely to be a closely guarded trade secret.
Based on some general industry knowledge and reverse engineering Porsche's warranty limits I think one can say the following are the general parameters of the Taycan's expected battery life.
1250-1500 500-800* - full charge/discharge cycles
40,000 to 50,000 kWh's in & out in terms of battery usage
* - revised downward given kWh capacity of this many "full" charge cycles - no one outside of Porsche honestly knows - so please again use your best judgement as to if you agree with me.
these numbers are inline with published industry standard LiON engineering cell specs - and show a healthy margin of error for Porsche's warranty to live with in based on my analysis (8 years/100,000 miles).
Expected life of a LiON battery is: the Battery will lose no more than xx% capacity in the defined warranty period. In the case of Porsche I believe the warranty is trigger at 30% total capacity lost (please feel free to correct me).
500 full charge cycles @ 83.4 kWh = 41,700 kWh's
800 full charge cycles @ 83.4 kWh = 66,720 kWh's
1250 full charge cycles @ 83.4 kwh = 104,250 kWh's
1500 full charge cycles @ 83.4 kWh = 125,100 kWh's
50,000 kWh @ 3.2 miles per/kWh consumption = 160,000 miles driving
30,000 kWh @ 3.2 miles per/kWh consumpption = 96,000 miles of driving
160,000 miles @ 10,000 miles a year = 16 years
160,000 miles @ 20,000 miles a year = 8 years
these are pretty common stats for a consumer grade street car. And most ICE vehicles will need some sort of major service in 160,000 miles - and battery cost is inline with any other major drive train component for this sort of longevity expectation.
Now Porsche states warranty is only after a loss of 30% total capacity in the warranty period - so some loss is expected - up to 30% apparently - this means your Taycan which could go about 270 miles when you drove it off the lot is expected to only be able to drive 189 miles towards the end of the warranty period on a full 100% charge.
I have no data/information as to how much "buffer" is built into by Porsche to these numbers. As to if Porsche hopes to exceed these expectations no one outside of Porsche knows this - I'm simply saying 189 miles of range at 99,999 miles and 7 years and 364 days would NOT trigger the battery's warranty.
DISCLAIMER: I have NO access to internal Porsche information - this analysis is for entertainment purposes only - it's not a binding analysis that you can take to your local service advisor.
I arrived at these conclusions from a broad experience with EV's and their general characteristics and reverse engineering various factors from generally true metrics we all can agree accurately represent the Taycan's consumption of battery power.
comment, questions, and discussion is welcome.
* - SWAG = Scientific Wild Ass Guess - yes data was used to infer the results, but it still is a reasonable guess as to the conclusion because it can't be proven, but the results asserted are reasonable from the premise.
