How to set to profile to only charge to 85%

[Scandinavian]

I don't know if it is a peculiarity of UK cars but a profile on its own will not work.

I'm on my 2nd Taycan now and profile only charging failed spectacularly on both - general or location based profiles (type of profile is irrelevant). The car would always continue to charge past the minimum set and so charging to 100% would be the consequence of that.

Wasn’t there something about this discussed earlier? I could not find it when looking for it though.

If I remember correctly it will charge up to 85% and stop, BUT if you do not disconnect the charger at that point it will start charging again after 30?? minutes.! Not 100% sure about 30 minutes but there was a specific time. If however you also set a timer with a target charge rate (higher or same%) and set repeat all week, then it would stop???

I think the logic was along the lines:

Set a minimum charge level and car will start to charge when plugged in.​

When charge level is achieved, charging will stop and look for next instructions​

If next instruction is to charge to a certain level much later in the day, charging will pause​

If there is no instructions set, charging will start again and charge to 100%.​

​

So as the OP wants to charge to 85% but does not have a specific time when leaving the office, it should work to set profile to 85% and then timer to 90 % at midnight with repeat for weekdays.

My car is at it’s second service at the moment, so I can not try this out and verify.

The work around if you want to just charge straight away to 85 % is to leave the optimised button ticked and it will charge to the 85% and stop without any problem.
If you want it to start and stop at a specific times then you have to use timers as that is what they are for.

Profile only set to 25% minimum and preferred time of 00:00 - 07:00 and no timer active led to immediately charging my battery which has 53% SOC and it was 16:00 in the afternoon.

Profiles require a follow on event such as a timer to control the stop and if this is not present it will continue to charge.

There is a 30 min trigger too - in the owner's manual - where if EVSE is left connected and there is no programmed event then charging will resume towards 100%.

OP hasn't made it clear on 'off peak' or 'ready by' use case.

These days I don't bother now and use OVOs Charge Anytime app which overrides your own profiles and timers with its own based on OVOs off peak periods. This is a revelation and the car will charge optimally and cheaply throughout the day. You can still set a departure time and min charge level too. Overall just perfect and cheap - 0.10p / kWh compared to 0.36p or higher.

Hi all, new taycan owner here

I’ve read through this thread but still a little confused as to which charging option would suit me best and hope one of the veterans could advise.

my charging habits are somewhat ad hock as I charge exclusively at my office. I have no proffered charging times throughout the day and my ideal would be to set the charge limit to 85% so that whenever I do plug in it tops the battery up to that level.

my impression from this thread is that I should set the ‘minimum charge’ to 85% on the general charge profile and not bother touching the timer at all. Anyone able to confirm this for me?
Thanks

I don't know about the UK, but for those of us who are old enough to remember what a VCR is, the Porsche charging logic is worse than the VCR programming logic from the 1980s. The proof of that is that your question is asked repeatedly (https://www.taycanforum.com/forum/threads/how-to-charge-immediately-but-to-85-only.12732/post-189071). Further proof of this is that a quote from the most referenced tutorial video (Paul Steinbruner) is literally "The minimum charge is actually going to be the maximum charge." Unlike the Tesla, there is no "simple mode" where you can have it always just charge to a set limit, no matter where you are or what charger type you are on.

For home or public level 2 "charge to 85% and then stop," disable (or don't set any) timers, and set the General Profile to 85% minimum. Check the General Profile box. When you plug in, the car will charge to 85% beginning immediately, and because there are no follow-on instructions, it will then stop.

In the US, we get free public DC charging on the VW network (Electrify America) - worth many thousands of dollars over three years. So I use that when I go to the mall. If you use a public DC charger and go for a bite, the Taycan ignores the timers/profiles etc and always fills you up to 100% unless you remember to stop it. This is incorrect behavior and the person at Porsche who designed this should be taken out back behind the woodshed and beaten. That may not be the case if you are using the range manager and on a trip, where it calculates stops and charge times, but I haven't tried that and it isn't my use case.

Also, similar to the Tesla, for fast charge, the way to pre-condition the battery is to use the Porsche PCM to navigate to the DC charger, preferably 10-30 minutes away. It then starts heating the battery.

For me here at home or any L2 charger, the power is always the same price so as I said, I wish there was just a big override button that makes it always charge to 85% on plug-in, no matter where or when or what type of charger.

I'm of a certain age to remember pre VCR programming - I managed that just as easy as 2.5 years of Taycan charging in more modern times.
But can speak with quite some confidence that in UK / Europe a timer is required to control the session.

Fundamental issue (as always) IMHO people just can't be bothered to read the manual.

it’s way easier to just take the engineer behind the woodshed and beat them.

Okay okay, I will go read it. So will adding a timer with a particular setting make it so that I can plug in to a DC charger any time I show up at the mall, walk away, and it will limit to 85% and not burn out the battery?

That is not the intent or the point of _fast_ charging - the idea is that you’re on the road, charging directly and as quickly as possible to a suggested target. If you ignore that suggestion then the next target is obviously “full”.
Also, it’s not “free unlimited” charging, it’s “free 30-min charging sessions“. You’re obviously entitled to start immediately another session (for free), but the time cap is there to discourage parking at the mall and leaving the car for hours, occupying what still is a scarce resource.

I have my car set to charge overnight (lower electric rates). Your post made me question whether I had ever actually let the car sit plugged in with no timer set and waited to see if charging resumed after some period of time elapsed. Tested it today. Turned off all timers and only the general profile was active. Set to a minimum of 70%, optimized charging, no precool/h. Car immediately began to charge. Stopped at 70%. Displayed "Charging process completed". It's been about 3 hours since the car reached 70% and there has been no further charging and the message is unchanged.

I am in no way disputing what you experience with your cars. Your charging process and mine are current "tests". Your car should not resume charging while mine sits at the minimum. The way the car behaves for something as important as the charging routine should be uniform. Exchanging information is kind of a crap shoot because of the way different cars behave.

 

[eddieterry]

Yes it will work perfectly if optimised charging is left on.
The problem is for people who cancel optimised charging.
The charging system is uniform.

Normal profile does this. Delete any timers and unselect direct charge.

 

[Raphie]

Ignoring all the timer advises here, doing what the Porsche guy said in his video:
-delete all profiles and timers
- put standard profile on 85%
- enable optimized charging

Charging stops @ 85%, can leave cable in, have left cable in for another 5 hours, it did NOT continue charging to 100%. Finally.

Yes sir, that works and I do that at home. But neither that nor optimized charging battery friendly charging, which is supposed to save the battery, limits charge level at a DC fast charger.

 

[AndiL]

@hifi239 There is no setting to limit DC charging. These settings are for AC charging only.

Correct, the Taycan has NO setting whatsoever to limit DC charging! It will charge as long as it is plugged in, which is a design flaw in my mind
