Charging to limit without delay using Mobile Connect

[PickledRamps]

I acquired a Taycan 4S last week. Transitioned from a Model S. I am having difficulty understanding the relationship between the act of plugging-in; the profile; and the timer.

There is no difference in peak vs off-peak electricity with my provider.

I am using a Porsche Mobile Charger Connect.

I want the car to start charing when I plug in, and stop at 85% and for the battery to be preconditioned at 7A.

I am not clear on the purpose of the profile if I don't care about "optimized charging", nor "preferred period", which I do not. Why do I want a "minimum Charge". Why not just start when I plug in until a max is reached?

It appears that the only way to set a max is through the timer? However, I want it to start immediately when I get home each evening, not leading up to a set time the next morning.

Then there is this "Plug & Charge" option in the PCM. Not clear how that factors-in.

This is a much better car than the Tesla, and I suppose I just need to get accustomed to it, but it feels very convoluted.

The charging setup is way, way too convoluted but usually can be made to do what the driver wants to accomplish. Under profile you can set up a home (location specific) configuration. Set your 'Minimum charge" to 80%. This is very poorly labeled. What this setting does is set a minimum level when you plug in. Usually set at 25% so that you have a decent charge for an emergency local trip. Charging will resume based on a timer setting. So if you set the minimum to 80% your car will immediately start charging and stop at 80%. Now set a timer to 85% and 7am with climate control active. I don't think you can have the profile charge to 85% and have it precondition at 7am without additional charging. The car will go to 80% immediately upon plugging in and sit until it needs to charge again to be ready at 7am. I use the Tesla EVSE "dumb" wall connector so all my settings are in the car. No idea if what you want could be accomplished through the PMCC as well.

"Plug and charge" is for DC charging. If active, and if EA is cooperating, you can pull up to an EA charger and simply plug in. Communications between the car and charger are automatic.

Thanks. I haven’t tried it yet, but I was told by customer support that in addition to EA charging, plug and charge would make the Taycan start charging as soon as connected to home charger. If true, to me, that makes the profile seem unnecessary.

I suspect they were referring to "Direct charging", which starts charging as soon as you connect and will continue charging to 100% (you can not specify an upper limit). As far as I know "plug and charge" is strictly DC charging and has no connection to level 2/home charging.

Like you, I migrated from a Tesla Model S. Just so easy to live with. Intuitive. You need a different mindset with the Porsche. German engineers seem to over complicate things. Not to mention the odd translations from German to English. Their logic becomes clearer after a while. Still doesn't explain why they did it the way they did, but you can get the results you want. You just have to work harder at it.

That is not correct. Plug and charge is for DC charging.

If you don’t set a timer or profile and you connect to an AC charger it will start charging as soon as you plug in and charge to 100 % also without plug and charge.

Not true, P&C is for hands free payment at a participating provider such as Ionity, EA, Porsche. No need for an RFiD card, app or other authentication method.

Documented in the Owner"s manual.

No association at all with profiles or timers.

Note that profiles and timers are only relevant when AC charging and are ignored at all other times

The Direct Charge button overrides both profiles and timers to commence AC charging immediately.

Use a profile and departure timer to control an 85% charge and be ready at 7. Set a minimum charge level eg 85% to commence immediate charging and use the timer to control end time and preheat. Note that preheat is the only way to precondition the battery when home charging.

Guys, the Plug & Charge settings in the Taycan DOES mean it can authenticate the car with a PMCC or PWCC if that device is protected with a PIN!

For that to work, enable the setting in the Taycan, plug in the car, and the device will detect the EV and ask for it to be added. If the PMCC/PWCC is protected via a PIN, you then do not have to unlock it before charging starts.

Perhaps this is what she was referencing. It’s not relevant to me as I do not use PIN, but that makes sense.

All very helpful. Much appreciated. A few scenarios

1. In other threads, it is noted that if one sets a profile to 85%, and do that alone, while that is a “minimum”, it will act as a max because the car has no reason to charge further.
a) Is that correct?
B) I suppose the downside would be no preconditioning because no timer is set?

2. In the scenario above, or with the use of profiles, in general, if one sets a profile to “optimized charging” and has no inputs regarding peak/off-peak electricity, nor solar, nor Porsche Home Energy, it then does nothing - car starts charging upon plugging and continues to minimum?

3. If one does not care about timing of energy usage, it sounds as if the primary reason to use the timer is so that the battery is preconditioned at departure time?

4. If one only uses the timer, and not profile, because one cares about battery preconditioning, especially in NE winters, will the car start charging upon plugging the previous evening, or will it try to time the charging to be complete at designated time?
a) if it does start charging immediately what’s the point of having a minimum set in profile when directing energy consumption is not necessary?

That would 100% explain why I never put my PIN in - marvellous!

The car will always immediately start charging und won't stop until it reaches that limit. "Minimum" is meant in the sense of: "I always want to get this SoC as quickly as possible".
So this seems to be want you want.

B) I suppose the downside would be no preconditioning because no timer is set?

Preconditioning the cabin (!!) can either be set with a timer or manually via the app. You can not set a maximum power or current for preconditioning to be used. The car will take the power it needs. The battery can NOT be preconditioned other than by charging it.

2. In the scenario above, or with the use of profiles, in general, if one sets a profile to “optimized charging” and has no inputs regarding peak/off-peak electricity, nor solar, nor Porsche Home Energy, it then does nothing - car starts charging upon plugging and continues to minimum?

Optimized charging needs an compatible energy management system to tell the PMCC (which in turn tells the EV) when charging is best/most cost effective. For that to work, one HAS to use timers. Because the minimum SOC has to be reached as quickly as possible not caring about costs.

3. If one does not care about timing of energy usage, it sounds as if the primary reason to use the timer is so that the battery is preconditioned at departure time?

See above, you can only precondition the battery indirectly by charging it. If you care about preconditioning the battery, you have to use timers and make sure it charges for a reasonable amount of time before leaving.

4. If one only uses the timer, and not profile, because one cares about battery preconditioning, especially in NE winters, will the car start charging upon plugging the previous evening, or will it try to time the charging to be complete at designated time?

Never tried that. Try it out and see what happens.

a) if it does start charging immediately what’s the point of having a minimum set in profile when directing energy consumption is not necessary?

See the explanation above for what is meant by the minimum SoC.

It will start charging immediately up to 25%. It will delay charging to be done at your departure time beyond 25%.

Just plug it in with out a timer & it will charge to 100%

Yeah not what the OP wanted - 85% is the target.
