How to set to profile to only charge to 85%

[hifi239]

Yes sir, that works and I do that at home. But neither that or optimized charging, which is supposed to save the battery limits charge level at a DC fast charger.

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

I believe you mean "General Profile," and yes, I know that works if you set the minimum charge to, say, 80 or 85%, disable any timers, and plug in. But no such state of charge limit is available for DC charging.

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?

Timers and profiles have no impact on DC charging and are ignored.

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

Can you imagine the chaos at DC EVSE locations with people taking longer than needed due to timers in the mix.

Most deliberately not a design flaw but a necessity.

As it’s been explained repeatedly on this thread, that is by design. Please don’t hog public high speed chargers.

You have a point if both the timers and the profile should be left active for both AC and DC charging. That could cause chaos.
You do not need to set any timers whatsoever. Just set a max charge level say 85% for both AC and DC charging and plug in. Charging should start directly and stop at that level. Only when you charge on AC should the timers come into play.

Tesla does this and then you incur charges if you do not unplug after a certain time after charging has stopped. As a charge for occupying the SuC.

Tesla lets you set a charge limit for DC (which is the same as AC) so your car/phone app tells you when it will reach this limit, how much time remaining, so you can plan to be back in time. Yes, they also charge idle fees if there are less than some percentage of unoccupied chargers at that location.

Taycan notifications are not real-time enough to be used for this. The darn car-server connection is flaky too, I've gotten both the privacy mode showing on the phone and the phone telling me it could not connect to the car (even though it did, since I sent an unlock doors command though the app, and the car did unlock after a minute, but the phone app said it coudn't connect to the car - all while the car has full 5 bars of LTE coverage (it's sitting 3 feet away from a Verizon femto-cell in my garage).

Luckily not all EVs are a Tesla!

They have the world top selling EVs, though BYD is close on their heels. Porsche didn't even make the top 20 EV's in January this year. It's in the niche market volumes with the likes of Lucid and Rivian. It is hard to produce cars in volume. Porsche, along with Rivian and Lucid, claims they are limited by their production capacity.

No you can not do this!
It was on my wish list and how I had expected the Taycan to work. Charge limit independent of charge by AC or DC.

I am sure the engineer that specified the charging had good reasons from an engineering viewpoint, but it is too complicated for most.

Sorry if I misled you.

As far as I can tell, there was no user experience design. Porsche implementation of charging options appears to be just implementation of the concepts straight from the engineering spec - the ISO 15118 standard. I don't think the spec ever intended this raw level of controls to be exposed directly to the end-user.

Precisely and that's a good thing and keeps Taycans more desirable rather than being massed produced.

To be fair Porsche and other Euro manufacturers have had it hard the past 12 months (there's a war on remember) and the JIT manufacturing weaknesses laid bare for all to see.

I'm not a Tesla fan or fan boy. I respect what Musk has achieved hugely but that's it

Can the DC charging be stopped manually from the Charger App or Porsche App.
I do not have mine yet, so very sorry for asking may be the obvious.
I had a loaner and had to charge at EA station, near a restaurant.
I was watching it charge on the EA App, then I remember that I could stop it manually when it reached desired SOC. I assume at that point, idling fees would apply but that would be fine with me. I was the only one charging with plenty of stalls available, but if someone would be waiting, then I would not have any problem going out and parking it at a regular parking spot.

So upon the suggestion, I went back and read the manual. It's not particularly informative. Seems a lot of it was written by the lawyers. The charging part is jammed as an afterthought into the "Mobility and Minor Repairs" section, putting charging in the same category as the proper use of fix-a-flat!

Clearly, the complicated profiles and timers are meant for level 2 at home, which I now understand. I was naively ticking the "optimized charging" box but learned that feature doesn't do anything without an installed device at your electrical panel called a Porsche Home Energy Manager (HEM). For me, I believe I have a 40 amp panel margin at all times, and no preferred charge times, so I don't need any of that. But I see how one would.

And indeed, there is no way to limit the state of charge with public DC fast chargers - perhaps they will fix this OTA someday. In a 30-minute session, when I run into the mall, I can easily charge well beyond 85%, depending on several factors such as battery temperature and initial SOC. I'd like not to have to monitor the SOC on my phone. I understand the arguments about getting in and out of the fast charger, so maybe a reliable 80% or 85% phone notification is the right answer. It would get me back to the car and off the charger even sooner, and at least the battery isn't stressed if I'm not going on an immediate trip.

I tried the charge planner to see if it would stop charging at the required SOC. I set the Charge Plan to give an 80% SOC at the destination, then I set the destination to be a DC charger, and set out with less than 80%. The charge planner and the EA DC fast charger both showed 15 minutes to get to the 80%. The EA charger shows a "line" in the charge level display at 80%. like it knows when to stop. But when it got to 80%, it happily kept charging. No phone notice. The EA app, on the other hand, does provide a feature to notify at a SOC, but we don't use this for the Porsche plug-n-charge.

You are quite confused. In the charge planner when you set the charge at destination, that is the desired SoC of your vehicle when you reach your destination. It has nothing to do with how much you want to charge your vehicle. DC charging will always keep charging until you stop it or until 100%.

No confusion. That's exactly what I concluded after this experiment. If you are saying I should have known this already, I certainly don't see anywhere in the manual that says that. I was wondering if there was _any_ scenario where the car would stop charging at less than 100% at a DC fast charger.
