Has anyone experienced a problem with delayed charging profiles?

[JCB]

I have created a charging profile that is supposed to start charging at 9pm when the rates drop, but the car starts charging as soon as I plug in the charger. I also specify that the car stop charging when it reaches 80%, but the next morning, I find the car is charged 100%. Am I doing something wrong?

You need to set BOTH a charging profile AND a charging timer that work together:

Easiest thing is to just set a timer for a departure time and skip the profile (leave off).

You can’t just program a start time.

You can try setting a profile with your optimized times and min charge of 25%, but you’ll still need the timer. All the profile will do is try to use the optimized times for the timer, but if the timer is within the optimized time, it’s irrelevant. And it won’t keep if from starting earlier if it needs to.

So it’s easier and typically the same results to just use a timer.

Where in STL are you?

Let me see if I've got this. Don't have the Taycan for another 3 or so weeks, but I've done a lot of reading about this. Those of you with more knowledge please be brutal with your corrections.

Profiles are associated with physical locations. For the physical location defined in the profile (Home, Work, Cousin Ed's) you can set a minimum charge and preferred hours that define when charging is cheap.

Without an accompanying timer, the profile causes the car to immediately charge to whatever minimum charge you've set for that location. If you aren't at a specific profile location it immediately charges to the minimum set for the general (AKA anywhere else) profile.

That's assuming all profiles are enabled. If I'm at work and plug in, but the work profile is not enabled the general profile applies.

At home, I set the minimum to say 40% or less because that will always get me up to 100 miles of range immediately. I also set a preferred charging window of 11:00 PM to 5:00 AM because that's when my rate is 7.9 cents/KWh.

At work, because it's no cost to me at any time, I set the minimum to 85% and don't bother with the preferred hours.

Cousin Ed is kind of particular. He says I can charge from 1:00 AM to 3:00 AM and that's it. There I set the minimum charge to 5% and the preferred hours to Ed's two hour window.

Then, for the general/everywhere else profile I set the minimum charge to 95%. It's set high because if I just plug into some random charger I generally want the car to charge.

Now, if all four profiles are active, when I plug in at home the car immediatly charges to 40% then waits. At work, it immediatly charges to 85% then waits, and at cousin Ed's it waits. Everywhere else, if I plug it in it will charge until it hits 95% or I unplug the car.

To charge above those minimums you need a timer. I'm going to set up two.

A weekday timer that says the car needs to be 85% charged and preconditioned to 68 degrees at 8:15 AM.

A weekend timer that says the car needs to be 85% charged at 8:00 AM, but I don't care about preconditioning.

This all works well until I decide to visit cousin Ed. The profile says 1:00 AM to 3:00 AM, but the timer says 85% by 8:00 or 8:15. The car is going to calculate how much power it can draw, and if it can charge to 85% after 1:00 AM it's going to start charging at 1:00 and be at 85% the next morning even if it has to charge after 3:00. If it needs to, it will start charging before 1:00 AM to meet that 85% goal.

Best not to plug in at cousin Ed's at all really.

As to the OP, my guess is that the general profile is currently set to charge to 100% and any location specific profiles are currently not enabled, or aren't actually associated with the physical location the charging is happening at.

Profiles always charges to min immediately. No exceptions. With or without a timer

He’s probably using preferred times without a timer.

If you set preferred times, those are preferred times for other charging (e.g. a timer) or it will go to 100% in the absence of a timer.

I have now set a timer in addition to the profile with the preferred charging times. And...the car is still charging as soon as the charger is plugged in. It won't go into a "Waiting" mode

It charges to the min in the profile immediately no matter what. You probably need to lower your min.

It charges to 25% immediately in the absence of a profile.

Ahh, thank you I had not put that together. I was under the impression that absent a timer it would stop at the minimum associated with the profile and that would be it.

That’s the behavior if the profile is set to optimized.
Preferred times will continue to charge though.

Wait isn't optimized only useful if you also use the Porsche home energy manager? Though I suppose it makes sense, if you select optimized the car would sit waiting for the home energy manager to give it permission to start charging and therefore stop at the minimum.

Yes, it serves other purposes with a HEM, but many people (myself included) just use a general profile on optimized with the min set to the desired charge to just charge to the that level immediately, stop, and then do nothing else.

Edit:so, it’s still “useful” without a HEM, but in a different way.

It charges to 25% immediately in the absence of a profile.

Ah ha! I watched the video for the third time and realized I set the Profile min charge to 85%, thinking this was the max like in the General setting. Once I correctly set the Profile to 25%, viola! It worked.

It’s not the max in the general profile either. It’s still the min.
