air conditioning timer and decoupling battery conditioning

[lory995]

Hi everybody,
i've read many post on this forum about how this car is not a tesla and there isn't a function or a timer that can keep the a/c on or activate it on a timer. I've also read that it could be done only if you "sacrifice" the energy for the battery preconditioning because the usual timer used in the morning by everyone condition the battery too.

Now most of the questions i saw were actually quite old so my first question would be,
has something changed in the meantime? Is it now possible to have a timer or keep the a/c on more than the usual 60minutes after the car shutdown?
Is there now some way to decouple the battery preconditioning to the car climate control?

i don't have much hope honestly,
prove me wrong.

The timer function only affects cabin climate control, it does not precondition the battery. The only heating of the battery you'll get is from the actual charging. The only time you'll get the car to warm up the battery on demand is to navigate to a fast charger in the PCM.

Are you really telling me that i can, for example, sleep in my taycan by setting something like 1 timer for each hour, and these timers don't touch the battery at all?

Are you sure that when you setup your timer for when you wanna use the car in the morning normally, it doesn't pre-heat the battery too?
I'm sure i've read something different in this same forum, so something has changed ?

Yes, we are sure. There is no function in the CAR to pre-condition the battery (increase its temperature to optimal fast charging DC temp), exactly as@mystermykee, said, unless you point the car to a DC charger in a PCM, or you drive in Sport+, or may be doing a so called a yo-yo when driving. There is nothing you can do to pre-condition the battery when the car is stationary.

I am not following your questions about A/C needs. The only thing the car can do is so called pre-heat or pre-cool the cabin to set temperature for 60 minutes max from the App or in the Car shown as a countdown timer, or as an add on to the home charging Timer so the cabin gets to the set temp by the time set. This has nothing to do with pre-conditioning the HV battery for driving or charging.

Not sure where you read anything different on this forum, since we are pretty quick in correcting misunderstandings.

Sure, I guess the battery temp might increase a few degrees because of usage. Any heating/preconditioning of the battery you get from the timer is a byproduct of the car trying to reach the target charge. If battery temp is at 70 degrees and I’m only 10% away from target charge, battery is not getting anywhere near optimal temps.

Ah, well then i'm sorry i must have misread. So no battery pre-conditioning, ok.
But then again, since my question started from a desire to sleep in my car while in a camping spot ( without the roof tent ) the most important part was if it was possibile to use the timer/ keep the a/c on more than 60 minutes without intervention.
As said i read similar questions in the past on this forum ( regarding sleeping ) and it wasn't possible to time the a/c except the aforementioned 60 minutes.

The only thing the car can do is so called pre-heat or pre-cool the cabin to set temperature for 60 minutes max from the App or in the Car shown as a countdown timer, or as an add on to the home charging Timer so the cabin gets to the set temp by the time set.

Judging by this anwser seems to me that nothing has changed, do you confirm?

No, unfortunately not only does the Taycan shut down preconditioning after 60 minutes, but if you are in the car with the power on it also kills the power after 30 minutes - suddenly and with a thump; you dont get asked first. You can turn it on again, but it also brings on the lights and you have to turn them off each time too.

I sometimes need to have an online meeting for an hour or two from the car and their design choice is very irritating. (cf tesla where I did an all-day board meeting in air conditioned comfort).

I suspected it, i wasn't hopeful. I truly don't understand the reason why though, even more so since the software team is shared with all the VW group and more control would be a feature very much appreciated; i understand sleeping in a porsche is not porsche-like ( even if they sell the tent so they know you'd love to go camping with your awesome car ) but sleeping in a ID4 or similar would be a different story so doing a camp-mode or at least animal mode / ac control ( to work in the car as you said )would be the minimum i'd expect....

Anyway thanks everybody for your answers, appreciated.
