Charging profile

[jamesmaine]

New to Taycan, 2022 4s
I have profile set to minimum 25%
charge 12-6 Am although time of charge not an issue for my electric supplier
Timer set to precondition A/C for my next use, next Monday, charge turned off and precondition turned on
Checked the car with app 36 hours later and it shows 88% charge, 12 hours later 97% charged
I have used this timer and profile previously without it charging the car.
Any thoughts why this setting resulted in the car charging?
Thanks

Perhaps Direct Charging in your PCM has been selected? (That overrides all settings and starts charging immediately; comes in handy if travelling and using a Level 2 charger)(if not selected when using L2 chargers, charging may be delayed depending on your settings)

 

[jamesmaine]

Direct charging is off, thanks for the suggestion

The best way to help you is for you to state the case of what you want to accomplish a bit more clear, such as: every day (only a Monday is a major red flag already), I plug in at night (at this SoC % usually), want SoC to be this % by 6am, and be preconditioned. This will drive what settings apply. It is not efficient to reverse engineer your settings to the behavior you are seeing.

 

[jamesmaine]

Here are the settings
Goal is: started with 70% charge
Left home for a few days, dealer stated if you don’t drive the car for a week plug it in to maintain the 12v battery (is that statement correct)
So I plugged it in with above setting to maintain the 12v and as a bonus precondition the car for my next drive
Are my settings consistent with my needs and is anything needed for the 12 v if the car is idle for a few dsys
Thanks

First, 12v is not maintained if the car is plugged into the home charger.
Second, a week is too short to worry about 12v battery if all systems working properly. 50% SoC recommended and a few weeks of non-use is acceptable.

That means your dealer is clueless, so let's get that out of the way.

Let's start with Profile.

Profile with Preferred interval - why are you complicating your setup if that does not matter to you.

Profile with Home address - why are you complicating your setup if this is your only Home where the default Location independent profile is better.

The car will charge to 25% right away regardless of settings (Timer, Profiles, Direct, whatever) including total disregard for your Preferred interval. This means if your car is at <25% when you plug in, you cannot make the car wait until your Preferred interval to start charging.

Then the car looks for the next command in this order after it reached 25% emergency minimum that you cannot control with ANY settings:

1. Direct - obviously will charge to 100% as fast as possible.

2. Profile - the car looks at the % setting and charges to that level as soon as possible, recommended to be set at 85% then STOPs, and looks for the next instruction, which is the Timer. It will honor Preferred interval after it is at 25% minimum.

3. Timer - the car looks at the % level and end time and calculates backwards how many hours it needs to get there given a quick sip of the current Amps. For example, if it only needs 3 hours and end time is 6 am, it will start charging at 3am. Then STOPs and looks for the next instruction, which is another Timer event (same timer but recurring) or another Timer (dummy set on the far future). If it does not find one or another, like you have July 7 one-time Timer, it will RESTART and will charge to 100% as soon as possible.

Therefore, you cannot have a one-time Timer setup - must be Recurring or you can set a Dummy one far far in the future for Step #3 above to STOP at the level set.

Therefore, if I understand your case correctly, this should be your setup.

Direct = OFF
Profiles = OFF
Timer1 = July 7 with say 85% and Pre-Condition
Timer2 = December 31 with 85% (dummy)

Thanks very helpful very thorough
And yes dealer was not very informed about the details of the car (brand dealer with high ratings)
Again thanks

@SergeyIndy thanks for your helpful post above. I am struggling with a similar issue and the dealer as well as the Porsche call line have been helpless - they told me to change my charger which seems like the wrong answer. The car should be able to start and stop the charging independently of the charger. Here is the situation:

I would like to charge my Taycan to 80% at night, starting at 10 PM or later and in time for an 8 AM departure (it is pretty hot in Houston, and charging it any earlier heats up the garage like crazy). I am using a Tesla charger with a converter plug, and do not use that to schedule the charging. I typically plug in the car when I return in the evening, but it does not seem to trigger it with the timer or profile consistently. Any thoughts on how I should set it up?

Thank you for the kind words. I am happy to help as this is a simple case. However, I want to disclose that everything that I am suggesting is consistent with how the car is designed to work, as if to say, if any systems in the chain have any issues (low chance), then the process will not work as designed. If that is the case, then we can troubleshoot with additional steps.

This is how I would set it up:

I am assuming 25% or higher SoC at evening plug-in time, say 8pm.
I am assuming that your EVSE is just providing power when asked. Disable any scheduling.

Direct = OFF
Profiles = OFF
Timer 1 Setup:
- Time = 8AM
- Repeat = ON (must select days of the week)
- Remote climate control: OFF or ON (your choice)
- Charging ON at 80%

Make sure verify it is in your App and in your Car.

What is going to happen?
if SoC <25% the car will start charging to 25% as soon as it is plugged-in and stop (cannot be controlled)

If SoC 25%+ the car will test the current for a minute or two, will not start charging, and will go into wait mode (blue) until it decides to start charging. Therefore, if the car calculates that it needs 6 hours to charge you from 25% to 80% by 8am, it will start charging at 2am.

If you let your car plugged more than 30 minutes after the end of the time set up in your timer then charging will start again untill you stop it manually or raising 100% SOC
Just look at your car documentation

Please do not get involved if you do not read my previous posts and you do not know what you are talking about and confusing our members on this thread. This is not what the OP and other members asked for. We are not here to point to manuals.

Your statement is only true if a one time Timer is setup, otherwise it is false, so it is not helpful, as it does not provide a solution like my posts above.

@SergeyIndy I set it up as you suggested (I had tried the same setup earlier too), and it seems to work sometimes, but not consistently. The car tests the charging rate when I first plug it in, then goes to “charging paused” blue light flashing on charging port with in-car charging saying ready at 8:00 AM. However it does not trigger the charging reliably - sometimes charges and at other times does not start charging. I think I will have to have the dealer replicate this behavior so they can figure out a fix.

That means 2 things to me. This may have something to do with your EVSE. Sometimes when the car calls for power, EVSE does not give it. So I would definitely try a different home use EVSE. You can get one to try and return. Then if another EVSE behaves the same as in, inconsistent behaviour, then there is something not right with the car and dealer would read the log that would report any malfunctions in the charging system.

My outline of the charging logic is how the car designed to work. Any deviating from that means something is not right.
