New owner '22 4S CT.. Time to edjumacate

Please do not confuse the OP if you do not exactly know how this works.

By design, no matter what the setting is, as I pointed out above, the car will charge to 25% as soon as it is plugged in, regardless of the settings. You do not need to set or have a Profile with 25% to make that happen.

Yes, I’m new to this car, but what I suggested works perfectly and I took the instructions from another thread when I had to set up my car.

I honestly don’t know if what you’re suggesting works because per the description in the App, it would only set a MINIMUM charge, not a maximum charge which is why I think he’s charging to 100%.

Screenshot from my app, I have mine charging to 95% by 8:30am daily:

In the car now.. trying to make sense of this..

As that states, that setting sets the minimum charge, not the maximum charge.

I used the timer to set the maximum charge.

This is not the right way to do it, but it works for you so keep doing it.
Terminology is confusing and a total mess - Porsche's fault. Minimum actually means Maximum.
Profiles and Timers do different things and serve different needs.
However, both will get you to the target charge.
I am happy to go into the differences.

All looks right, but to make it a quick test set Profile Min Charge to 80% as you at 76%.
Please plug in Emporia now and let me know what happens.
The car should stop at 80% and let you know via the App the Charging Session is Complete.

What is the right way? Because I tried what you suggested above and it doesn’t give me a maximum charge setting when clicking on preferred charging window.

This is the thread that said to use the minimum charge on general profile and then timers:

From that same thread, it seems like there is more than 1 way to do this:

“OK, so the subtlety here is: if you have a single profile with optimised charging enabled and NO timer set the car will treat the % set in the profile as a MAXIMUM and not charge beyond it - essentially the car charges to the profile % as soon as it can and stops, but because there are no other instructions it doesn't charge further.”

Seems like the difference would be whether you want the car to just charge right away to X% when you plug in (your way, no timers, but you can add a charging window).

Or if you want the car to charge right away to 25%, then slowly charge to X maximum % by 8:30am (the way I posted with timers).

I updated my comment above. The terminology is confusing. Please do not use Preferred Charging, unless you absolutely need it to save on cost of charging.

The way it works at the most basic level:

Case 1:
Regardless of settings, the car will charge to 25% if below as soon as possible and will stop to wait for the next instruction in a Profile or Timer.

Case 2:
Profile is intended to charge the car as soon as possible to the Set State of charge. Minimum actually means Maximum, so it will charge to that level, such as 85% and stop. This is by design.

Case 3:
Timer is intended to get to Target Charge by a Set Time and charge to the Target charge in Time to meet that Target. Therefore, if your car is below 25%, it will charge to 25% as soon as possible (Case 1), and then Stop to calculate backward how much time it needs to get to the Target charge. So if you are at 25% and need to get to 85% and the car needs 6 hours to get there but it has 10 hours to do so, the car will go into Pause, Blue Pulse, until it is 6 hours away from your Set Target.

Profile is usually used as the simplest method when ambient temperature is favorable to the battery.

Timer is usually used in combination with pre-conditioning so the battery and cabin are warmed up to optimal conditions for driving by the Set time.

Therefore, I use Profile in the warmer season and Timers in the colder season.

Yes, all of the above is correct. Sounds like we are on the same page. I explained in my recent post just now why I would use a Profile vs. Timer.

@69Mach390, thank you for hanging in there with me, and I apologize for making comments on your setup. This is the topic we have discussed for ages and hours, and I spent, not kidding, 2+ years trying to figure out exactly how it works by design, testing all different combos to really know the program, since I cannot be content as an engineer not to understand all the details. There are many quirks still that need to be considered when working with Timers, but I am not going to get into it, unless you want me to with a specific use case. Otherwise, going back explaining many ways things work is not productive.

Bottom line: Use simplest General Profile with your Target and make it Optimized. Anything else, you have to start knowing what you are doing exactly and what you need to accomplish.

Just as a follow up, I deleted my timer, set my general profile to the % max charge I want and it worked perfectly. Thanks again! Seems simpler for me as my cost to charge doesn’t change based on time of day and I don’t bother with cabin pre-conditioning in Florida.

Great feedback and recommended way to charge when ambient temperatures are ideal to help others educate themselves on the most basic and reliable General Profile method.

The only tweak that I do when I know that there is plenty of time to charge overnight is to lower EVSE output power to say 35Amp. I have the 48Amp/11kW output from the hardwired EVSE, so I only set it to max 48Amp if I need to charge fast, otherwise, I found that lower output does not warm up the EVSE and the cable as much.

Well @SergeyIndy & @69Mach390 we did it! Finally got an 80% charge.. not a 100%. I didn't do anything different from before. I opened the app and sent my settings to the car again. Went in the car, clicked on general and just redid it all. But this time it cleared.. almost like I cleared some saved cache.. have no clue. But we are good to go.

Kept it simple like @SergeyIndy suggested.. I really don't need nor care at this moment about charging timers. I'm self employed so I don't have a specific schedule on leaving the house and this isn't my daily (though its slowly becoming so).

Appreciate all the tips..

 

[SergeyIndy]

@Seattle996, glad it worked and helps others who may be in the same situation when the car does not work as designed. I would say deleting and refreshing everything is key before claiming car or charger issues.

Now, since you mastered the General Profile, there is a place and use for Timers, if you want to learn why and how to use them after you catch your breath. I will just point out the benefits of Timers: 1) Charge car to 100% in time for long trip; 2) Warm up the car in time for morning drive in cold weather without charging the car: 3) Charge the car in time for morning drive by warming the battery through normal charging; 4) Combine 2) and 3). However, there are some setup rules you have to follow, so it is not just creating one and hope it works, it will not, if you do not know what you are doing.

Gave her a nice little wash today.. froze my fingers off but it was worth it
