How to set to profile to only charge to 85%

[Scandinavian]

Yes but it depends if you left the optimised button ticked as if you want to just charge straight away to 85 % and then stop (as most videos show for AC charging) you need to leave the optimised button ticked and it will charge to the 85% and stop without any problem. DC charging is totally different and just charges to 100 % if left to do so.

Yes I left that button checked.

But please remember this optimised function only seems to being applied if you are connected to suitable equipment such as the Porsche HEM. There is a long description beside the setting outlining that this is the optimised to make use of solar power. As my test was done with a Tesla Wall Connector there is no connection to the HEM in my case. My PMCC is at service for check of SW updates.

The alternative was a preferred charging time setting which I ignored and left unchecked.

I have now had a chance to test this in the Taycan RWD loaner.

I set Profile to 75% in General and disabled ALL timers.
Car started charging as soon as I plugged in as expected and the loaner was equipped with the 22 kW option. Used a Tesla Wall connector set at 25 amp, 3 phase and got 16 kW. 16.9 kW drawn from supply. So about 5%loss which is ok.

Charging stopped at 85% and has been standing there now for 2 hours still plugged in.

If your cars have continued charging to 85% it would seem you there Is a difference in UK cars OR you have an issue with your car??

My experience has been the same on both my Taycans - 4S (2.5 yrs ownership) & GTS ST (1 month old) - so not the car(s).

We want to be able to set a minimum charge of 85% and to charge between a pre-defined period of time. You can't do this with a profile in isolation which is where this discussion (and on other threads started).

Charging beyond 85% if left plugged in once minimum charge has been reached was the second query. The owner's guide is ambiguous and from memory (a long time ago with my 4S) it ignored the 85% and continued to charge. This may have been a bug and addressed by Porsche over time.

Moot point (for me) my charging strategy works perfectly each and every time.

I honestly don't think the profile / timer logic is region specific - that would be mayhem.

I agree that would be a complete disaster.

My response was more tryto the following post

There was no need for a specific time at his office

Idle time should cost you as much as charging, per minute. I don't think what I just suggested encourages SoH behavior, $120 per hour for idling (you get charges as long as you are taking up the station) and a tow after say 45 minutes of idle, should quickly discourage assolish behavior, IMO.

Well, that's a bit extreme - I don't want someone to pay 40$/min, whether they are charging or not. (And perhaps I misunderstood your pricing scheme - it seemed to punish those who charge to 100%?) Nor having their car being towed. I'm just hopeful that people cultivate their empathy a bit more, and sprinkle some self-awareness on top. (BTW, just in case it wasn't clear, my beef isn't with you on the behavior, just for trying to help them out. ;-))

Btw, would you classify using the battery friendly charging option of the Taycan as "assholish behavior"?

Nope, that's under "not begrudging others their charging speed" - and that's even if I knew; mine's off, because I charge 'out' very rarely, when I'm optimizing for time.

I can beat that, [...] He probably costed me 5, maybe 10 minutes of time. I used it to walk around the parking lot to stretch my legs a little.

Look, I'm not whining about having lost a bit of time - as you say, it's usually a rounding error on a longer trip. What gets me boiling is the intent to idle/occupy a station, and demonstrating such a degree of self-absorbency as to only worry about the impact of exceeding the recommended SoC. As with everything, the vast majority will use such a feature responsibly - set a target, and then get to their car within minutes when that target is reached. But there will be a handful of those who'd use it for free parking at the mall (as an example).

There you have 2 large buttons at the bottom "Direct Charging" and "Preheat/cool". The former is the 100% charge button (direct charging means overriding all profiles). Latter enables cabin cooling/heating while charging & car locked.

Yes. A normal profile with the "minimum". The naming can be a bit confusing, but in a sense one can think of it as a minimum. Or maximum. Or a target. But what actually happens is that it charges to that number and then stops.

The button to override the profile and to charge straight to 100% is in the main charging interface where one can see the charge level and how fast one is charging (accessed from the screen where one controls the AC stuff and also opens up automatically when you start charging).

Isn't the "Direct Charging" for DC charging, not for charging to 100%?

The "Direct Charging" button is for AC only and it means that the car should charge until it is unplugged or the battery is full, ignoring all active profiles and timers.

It is the same behavior as having all profiles and timers disabled or removed.

 

[WasserGKuehlt]

Yes (that's wrong). Direct charging is really that - you connect the car to a power source, and it'll charge until full.

Not only that, but it's a sticky setting - you have to unclick it explicitly for any subsequent charging session (profiles, timers etc. will be ignored).

 

[Raphie]

DC doesn’t mean Direct Charging. Every single slider / switch option in the app is AC related.

 

[W1NGE]

Direct Charging button is for AC charging when you have profiles and / or timers active for home AC charging when at a public AC EVSE.

DC EVSE charging will ignore and bypass.

Read the manual!

I just had a reply from my energy provider. Porsche is aware and a solution in the app is in development

My suggestion was real simple:

• fixed rate per minute charge as long as you are occupying the space (practically as long as you are plugged in). I use $2/minute as an example which works out to be $0.50/KWh for the Taycan at max charge, but realistically it would be between $0.50-$3 per minute, depending on location. I threw in dependency on car max charge rate as a fairness to slow cars, but perhaps not doing that would be better, would encourage people to buy faster charging cars to save on DC charging costs.
• If you stop charging and are still occupying the station, say an hour later, towing comes into play, no different that when you overstay paid parking, or leave your car at a gas pump

$40 I was talking about was for the last KWh, not per minute. I was extrapolating slowing charge rate from my Tesla experiance. The very last 1 KWh on my Tesla can take 20 minutes (charge rate slows down to 3KW). I have not had the patience to DC charge the Taycan to 100%, but it also slows down significantly after 95% (I charged to 97% once, had a long hop ahead of me through the mountains, it was painful to watch the rate slow down). Maybe someone with a logging EVSE can tell us how fast the last KWh charges on a Taycan.

Look, I'm not whining about having lost a bit of time - as you say, it's usually a rounding error on a longer trip. What gets me boiling is the intent to idle/occupy a station, and demonstrating such a degree of self-absorbency as to only worry about the impact of exceeding the recommended SoC.

But there will be a handful of those who'd use it for free parking at the mall (as an example).

There will always be people who will abuse rules, or simply don't care. Like people leaving shopping carts in the middle of the parking lot, with the "cart garage" just a few steps away. It irks me, saw a woman do this today at a grocery store, sunny weather, no kids or anything, she unloaded her cart into her SUV, then pushed the cart over such that it was behind the car next to her, got in and drove off. I seriously think we should apply airport-like cart policy at grocery stores, put a dollar in (or swipe a credit card), get it back when you return the cart. For those who don't want to return, there will be kids who will gladly return a few carts to go get a meal at the food places next door. But I digress, was just sharing a similar example which irks me. I took that cart from the parking lot with me into the store by the way, was walking that way anyways, figured why spread bad will for when the owner of the other car comes out. As for DC charging, how do you explain this Chevy?

I never saw the owner, it was still there when I left (I didn't look if it was still charging or idling), but seeing it made me thing of inconsiderate people leaving carts in the middle of parking lots.

Oh geez I'm so confused. Normally I'd totally read a 17 pg thread but I'm in a little tizzy right now. I got my car back from PPF yesterday so did my 2nd charge. First was kinda partial and the electrician had just left and I was taking it to the PPF and didn't really know what I was doing, it was like 70% when I left for the shop. So I had it set to Maximum 80% when I came home from PPF (and a hell of a joyride as I once again blew past my house because I just couldn't stop).

Then last night I finally set up my preferred time of day rate with the electric company, and applied for the $500 rebate. After that I set a timer so it would charge between 12am and 6am. Now this morning it's 100%. Before I blame my husband for screwing with it when I said to let me learn first, what did I do wrong?

I have a Juicebox but didn't install the software for it because I didn't want the interference I've read about here. So if I want an 80-85% charge most of the time, AND need the timer for overnight, what the hell is the setting?

Sorry, it's one of those days.

Timer for 85% and departure time of when you want and make it repeat daily. Profile set to 25%.with preferred charging window based on the low rate times.

What if you don't have a regular daily departure time and you simply want the car to charge when the preferred charging window starts and end at 85% SoC, while charging at whatever rate the EVSE provides (in case of a balancing EVSE, that rate will vary depending on how many EV's are charging at the same time)?

 

[Raphie]

This is not possible, that’s the whole point, smart charging and a hard cap @ 85% cannot be combined. The slider initiates direct charging when below.
