@Rainforest, have you watched and taken note of this video? I think it explains a lot of options very well.

enjoy
I watched this some time ago but there are gaps in what is an otherwise comprehensive explanation and curiously he advises to use a profile and a timer for precisely the same reasons I do (around 9 mins in and onward) which is good to know.

What is missing for me is that he does not talk through the preferred charging times when using the General Profile and leaves that to the local profile (e.g. Home or Work). This is where it gets a little confusing. As far as I'm aware they would perform the same function as any other profile. Perhaps I'll try that out again (11 months ago when I last tried and gave up on it).

Yes it will be easier when you have the car! It is not the best user interface. A bit too complicated in my view and I can not really understand the reasons behind it. Yes you will be able to get the car charged at low cost periods etc, but that seems to involve the Porsche Home Energy Manager, which was some 560 Euros extra. The instructions for that one was even more fuzzy than the charger instructions. The electricians managed to get it to work he says , “ but please do not ask me for any further programming?”” :angry:
There were challenges I believe.
But all works fine now, so quite pleased with it all.
When you set a "minimum" in the profile (not timer) that is what the car charges to immediately when plugged in. Let's say you never want to be below 25%, so if you pull up to your charger at 15%, it will immediately charge to 25% (if that is your min setting) then stop. The timer is where you set your preferred charge to be at by a certain time. They can be used together to set a min/max, If you never want to be below a certain percentage and want to have a 85% charge when you leave for work or wake up. I only use the timer to have my car charged to 85% by 5:30am (so it calculates when to start charing to get it done by then), I rarely get so low during the day that I need to set a min. if I need more juice or I'm going on a longer trip, I'll just use direct charge.

If you set the min in your profile to 85%, every time you plug in it will immediately take you to 85%. a bit convoluted. I found when I used both together, it didn't always work as intended to I abandoned the "minimum" and just used the timer, works perfectly.

You were right. I set the general profile and it stopped at 50%. This is opposite of what some people have said where profiles only start charging below the minimum charge but do NOT stop until it hits 100%. But why does the battery continue to show the wavy animation even though it has stopped charging? See screenshot.

I think many people got confused in the early days but as more people are joining the forum they are possibly picking up on incorrect (or out of date) information and re-sharing.

A minimum charge is always defined as "the minimum state of charge (SOC) / battery charge you require to be available when you connect to your EVSE (wall box) and when that level is reached the charging process will stop" - this is intended to address emergency situations in case of a late night emergency and you want the assurance that your car will always have this minimum SOC regardless of what else you have programmed it to be. Therefore if you plug in at a SOC of 10% and have set the minimum to be 25% the car will start to charge immediately to 25% regardless of any other profile / timer function enabled. What happens after that is then determined by 'Set Preferred Charging Time' and 'Optimised Charging' to which further control / granularity can be added with the inclusion of a timer.

Can you remember what happened when you tried the General (or personal) profile (no timer) to set a min of 85% but within preferred charging times?

I think (but I may be wrong) that in the early days that the preferred times were ignored and so charging would just start. There is a chance that this was fixed as part of one of the major software updates we all endured some months ago.

I'm so happy (and confident) with the profile / timer combo that I never went back to try a profile on its own - when I have less time I may just do that.

have an off-peak period between 00:00 and 07:00 and generally charge to 85%. My SOC is rarely below my minimum charge (25%) and so most charging sessions immediately go on 'pause' waiting for the timer event.

I need to control the precise end time and optionally pre-heat (pre-cool is never needed in my climate).
Ok I can well understand your solution now. It is certainly a good one for your use case as you say. I have used something similar at home where I have different rates during the night and other times. Then the combination makes sense.

But I looked at OP and saw that there were no different rates over time. His use case was also so that he wanted to be sure to have the desired SOC as soon as possible after plugging in, if I understood it correctly.

There are a lot of different ways to set up charging and you just need to test it one change at a time to see what suits you best.

I don’t. I think @W1NGE ‘s car would basically charge the same with just the timer. I think the preferred profile time is superfluous given the existence of a timer departure time near the end of a profile preferred charge time.

I never used just the general, I had a combo of general for minimum charge of 30% and timer for 85% by 5:30am. If you use just the general and a minimum of 85% I believe that as soon as you plug in, it will start the charge and stop at 85%...I think

Yes, that’s correct.

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

Profile 25%, daily timer between the hours you need (leave sufficient time), preferred times set to the same.

I've posted screenshots of time and profile (location based) just emulate these. Don't need the general profile.

Without a timer you can't control the end time of a charging session.

A profile with minimum charge set to 85% would almost certainly start charging immediately - probably not what you want.

There is much confusion, noise and Ill advice on the forum. The process is simple.

Hi W1nge, thanks for your reply. forgive my ignorance, but why would I not want to begin charging immediately?

Electricity costs more at peak times and so most people consider when they would prefer to charge to optimise costs overall.

If this is not a consideration then just plug and charge up to the desired charge state. To end the process then a daily timer is recommended to control the charging window which suits.

If you could specify your typical use case then that would help.

What you describe should work the way you want. Set the general profile to a minimum charge level of 85% and select "optimized charging". Do not enable any timers. The general profile is not geo fenced so it will work at any location. With this setting any time you plug in the car will immediately charge to 85% and then stop.

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.
