Charging doesn't stop to the 80% limit set.

[lory995]

That's just completely wrong.
That doesn't make any sense.
This way it starts to charge to 85% immediately and that's it.
You only need the timer.

@lory995 : remove all timers and profiles, that'll reset the charging planner.
Set a timer to 80%, like you did before, that's all.

So i should reset the charging planner as you describe and just set it back up the way it was? or without a profile?
Not to sound mistrustful but isn't doing the same thing i did before usually leading to the same result?

For future readers, the easiest way to charge to 80% max is to:

1. Have no timer set

2. Set the general profile to 80÷ "minimum" charge, location independent, and use the option optimised charging. This will charge up to 80% when plugging in. It will still charge to 100% at fast charge stations or if you click "direct charging" when charging.

note 1: Why does this work? The optimised charging setting will communicate with a "smart" charger to only charge during certain times. Since 99% of all EVSE chargers are "dumb" this will only charge to the 80% "minimum" and then stop (as the charger will not give any "charge" commands).

note 2: If you still like to only charge during certain times of the day, then, in my opinion, it is easiest to set up a time schedule on your EVSE charger instead (that is, if your charger supports that). This will still respect the 80% max and the car just only gets electricity during the time schedule set on the EVSE. I use this charger for example.

That i'm sure will be very useful to someone with an EVSE which, unfortunately, i don't have. ( that's the first thing i tried to setup to be honest, it did make a lot of sense to me to directly control it trough the charger connect which of course doesn't do shi anything )
I'm sorry but i truly can't believe that it is not possible to set something like that. It's just unbelievable that some of the best engineers in the world screw this up so badly. i just can't.
I hope it's as @Dee or @BigBob have said and it should work but it doesn't for some kind of bug that will be solved in some way or another.

To be honest with all of you, the baffling thing is that most of you, with the best intentions of which i'm grateful, have provided some kind of workaround to "cheat" the system. Like we are talking about a patched up software of the 90s that for some reason a business still needs to use.
I expected something like: "you need to set it like this, noobs always make this mistake because the system is kinda complicated you know how germans are". Yet in the end i feel like i need to hack the mainframe just to have my car CHARGE TO THE RECOMMENDED-BASIC-COMMONSENSE 80%.

Sorry guys for the rant but truly the more i read this conversation the more angry i get at this 150k € car. Unbelievable.

Edit: And they could easily fix it with a software update.

Yes.
There is/was a bug in the charging planner.
If you don't reset it, it'll become unreliable.
That's why I said to remove all timers and profiles.
Use only the timer.
I'm using it like this and have zero problems whatsoever (Taycan 2020, own it for more than 5 years).

Some people use profiles, setting minimum to 80% (using it as a maximum....).
It works but that doesn't mean it is intended that way.

Some people really don't understand the way Porsche has designed it like this but I do (maybe I'm "special") but I can understand your frustration.

As others have suggested delete everything reset pcm and set up again. One thing to watch out for is direct charging has not switched itself on, that will always give you a 100% charge.

Just to clarify, my post works for any (home) charger. Also, EVSE = home charger, so I am sure you have one (I guess you meant that your charger cannot set time schedules)

Agreed. It’s baffling.
The software in the car is pretty poorly developed it seems to me (I’m not an IT bod).
So yes, people do have to do bodges and workarounds and total re-sets to get it to work properly. Maybe there is a better way, but no one at Porsche dealerships seem to have knowledge and at best they’ll just reinstall software. What I’m suggesting is reinstalling software light! It may make the car start doing what you want and it will be quicker than taking it to the garage.

Look, it's not that i don't get why they made it this way: A more complex system like this provides much more flexibility which is something that should be praised of course... but that's only if it works, isn't it?
Anyway now i understand it's simply a bug that's easily solvable so tomorrow or the day after i'll try it and i'll let you all know if i'll be blessed and won't ever have that problem again, in that case it's forgivable - no software it's perfect.
But thanks god there is this forum, if i'd have to ask a dealer....... good luck

Just to clarify, my post works for any (home) charger. Also, EVSE = home charger, so I am sure you have one (I guess you meant that your charger cannot set time schedules)

Yes mine is the mobile charger connect, without any smart controller in the outlet or in the panel so completely "dumb". That's why i needed the timer.

Thanks to everybody who helped me, i can't promise i will post if i'll be successful but you can be sure you'll hear for me if the problem won't go away Misery loves company

Hi everybody,
Just a quick question, as per title : After setting your profile ( min charge 25% ) and timer ( max charge 80% ) does your taycan keep charging?
I found out mine did it multiple times. This morning too i found it at 92% instead of the 80 i set.
After it did the first time i searched online and checked thoroughly my profile and timer settings but it doesn't seems like there is a problem there.
Is it normal? Do i need to contact my dealer?

Thank you in advance

I had a similar problem in my '24 Turbo S. I like to charge at night - it helps the power grid, and it is cooler in my garage (charging heats it up a lot). Not using a profile, and setting the timer target at 85% with an 8:00 AM departure was best. However the charging would sometimes work and sometimes not wake up at all. The dealer that I took it to, could replicate the issue and fixed it by deleting all profiles and re-installing the charging software. The car has been charging fine since.

If all you would like to do is charge it to 80% by the time you leave, use just the timer and not the profile and set the time and charge target. That should do the trick.

BTW, I get why the Tesla charging UX is simple, but not keeping the battery fully charged for longer than you need is certainly a good thing for battery health. So I can see what the Porsche engineers are trying to do.
