Charge to 85% - What on earth is going on!!!

[Dee]

Already 4 pages on a topic started today...?
All I can say: don't use minimum for setting a maximum.
Use a timer for maximum, that's it.
It'll screw up the logic behind Porsche's design if you use a minimum for a maximum.
Yes, I know it works with some members here but it's not how it's designed to work.
If you don't understand the logic behind it you'll keep on messing things up with profiles and timers, ending up charging to 100% every single time.

Yeah, I’ll try the convoluted daily timer thing, but even if this works it still doesn’t explain why there isn’t simply:
A) A maximum limit on profile
And
B) A pause/stop button on the main charging screen

having to guess all this profile stuff is pretty terrible design

I don't have any problem with it.
In fact, it makes perfectly sense but due to all the possibilities it's confusing for most people I guess. ?

What a lovely story.

absolutely adding zero value to this discussion though.

Have already said the specific public chargers being used don’t allow you to set any limits

There was no mention of you using public chargers in your original post. I will make a point of not responding to any of your posts again. Very sorry......not.

This is exactly why topics like this keep coming up again and again rather than being solved - because people like you keep making posts like your earlier one which attempt to dismiss the problem without bothering to read the rest of the discussion first.

Happy to shake your hand on your promise never to comment on one of my posts again. Deal!

The easiest way to have the car do what you want is to change what you want to what the car is doing. Have you tried just wanting it to charge to 100%?

Now there’s an idea.

Considering my car spends half the week sitting on the street in central London until I need to drive 10 minutes down the road to the gym and back, I’m not sure 100% is recommended ?

I’ll be in London next week if you need someone to drive it more for you. Happy to take that bullet.

Nor is a car!
When I lived in central London I didn't bother to own a car, there you are, problem solved.

Yep, the problem comes when you leave it past the time time. It just keeps going. You solution doesn’t prevent that.

It does - that's the point of the recurring timer as the session must wait until the next timer event before a new charging session can begin.

If you could share screenshots of timer and profile settings that would help troubleshoot enormously.

At this point I think we're exhausted and I'm not convinced OP is implementing the timer + profile guidance provided nor has fully read the Iwnanual on 'how to'.

Recurring timers are key to the charging session control otherwise unless the car is physically disconnected it will start charging again and only stop at 100'%..

It is possible there is a fault but the guidance I and others have given is 100% correct - no question.

Folks in US can achieve the same outcome with profile only but in the 2 Taycans I've owned since 2020 this method will not have the desired outcome. Not clear either if Porsche have a different implementation by region - I expect not.

Hi @Scandinavian - Yes, see attached.
With these settings I’ve tried combinations of:
- Only time set and profile off
- Only profile set and time off
- Both time and profile on

all overshoot 85% and just keep going to 100%.

strangely last night (only profile on as attached), I work up about 6am and it was at 85% saying ‘Charging process complete’, I fell back to sleep and when I work up a few hours later it was at 100% (grrrr ?). I had’t touched anything between those two events.

Why do you have a timer set to 85% if your general profile has the same set as the minimum. It seems redundant, no? DELETE the timer, you don't need it.

Also, is the General Profile enabled?

Or delete the profile.
Or only use the profile, set at 85% with direct charging disabled.

That is exactly the reason it doesn't work.
If values are the same, overlap or too close to each other it'll screw up all settings and it'll charge to 100%.
Minimum and maximum are called that way for a reason.
As long as you are fighting that logic it'll never work.
Or, indeed, read the How-to.

Since I followed the advice in the video from 2020, I have also had my car behave just like I want it to do. And that is nearly 5 years now! Only once a big hiccup, when the High Voltage Battery Controller and battery failed.

The one thing we never got any answer from the OP was the designed power of the lamp post charger in London! I have absolutely no idea of how much that can provide in kW, but my guess is not so much. If that power is only like a household socket, it would not charge in the window the OP set at all.

If the all the advice given here has failed for OP then there has to be a bug in his software.

Hence my original suggestion way back in this this thread, delete ALL timers, delete all profiles except for General Profile, set General Profile to 85% minimum charge and optimizing charging set, then make sure it's enabled. But the OP seems insistent on using timer(s) for charging setting them to the same value as the profile.
