In the Taycan's Brochure (On Page 51 under "Important Information") Porsche recommends that "the maximum charge status of the high-voltage battery should be set to approx. 80%" if you plan on charging the Taycan on a daily basis.

Their reasoning in the brochure seems to be "For physical and chemical reasons, the charging speed decreases as the battery approaches its full capacity. Therefore, it usually makes sense to use fast DC charging to charge the battery up to 80% or up to the required range."

I've seen this suggested for Teslas and other EVs, I assume this is the sweet spot for battery longevity?

Yes this has been set for other cars too, generally it is best not to go all the way up and even more importantly not all the way down to empty. And most importantly not to leave in either condition for long periods of time (I mean weeks not hours). But is there a setting to allow for max charge level? I don’t see it.

Yes, there is.
Actually quite handy: you can charge up to e.g., 85% based on GPS position (at home)…
You can also optimize charging to cost (I have very cheap power at night)

Excellent explanation:

in the newer "book" it has been lowered to 80% from 85%, it is only a few miles difference and for daily use using the lower number shouldn't be an issue
As a habit, if I do not need the miles, I tend to use a 70-30% range charging strategy. I leave the car "idle" at 40%, then raise the minimum or set a timer for up to 70% for daily use depending on how much I think I may drive. But then again I have option of charging at work and fast charging in my area, so YMMV.

Good to know. I don't charge my 4S every day as I live in a high rise apartment. Usually charge mine once a week and always go to 100%.

you need to read the manual, charging to 100% and letting the car sit is not good for the health of the battery

I do charge to 100% but I don't let my car sit. I drive it every day so I don't think I'll have any issues.

if you do not need the range for daily use there is no reason to charge to 100%, charging to that level is unnecessary and could result in harm to the battery

I stopped by my dealer today to pick up some parts that I ordered and while I was there I asked my sales associate about charging the battery to 100%. He said while the charging sweet spot is between 20-80% charging to 100% in the short term will not harm the battery as Porsche has set up the charging so that when you do charge to 100% in reality you are only charging the batteries to 83% of their capacity. He asked if I was going keep this car for more than 10 years to which I replied no. He said in that case don't worry about it.

your salesman is dispensing info that is contrary to what porsche says.
are you new to the ev world?
fwiw: tesla has the same charging limitations and while the porsche battery science is a bit different than tesla's the both use the same type of batteries and both react badly to sitting at very high or low SOC.
but if you think that your salesman is a better source of info, go with it

The fact of the matter is I normally don’t keep a car more than 2years so I don’t think it will matter one way or the other. For now I will continue to charge to 100% until I can determine my maximum range. Only then will I limit it to 80. Thanks for your concern.
