Taycan Profile doesn’t work with ChargePoint

[NormF]

When I charge my Taycan with an 85% Profile using a ChargePoint home charge at my cabin it blows by the 85% and will charge to 100%. Doesn’t appear to handshake with ChargePoint. Using the Porsche Mobile charger at my house using the same profile works fine and stops at 85%. Has anyone else experienced similar issues with non-Porsche chargers?

No, fine here. I suspect that's an issue at the car end rather than the charger end, since if the car stops accepting a charge the charger can't override it.
Do you have a Timer as well as a Profile?

I suspect it might be a Profile issue within the car itself, depending on if you have selected "Preferred Charging Times" or "Optimised Charging" the Minimum Charge level percentage operates differently.

Optimised Charging - the Minimum Charge is actually the Maximum Charge

Preferred Charing Times - the Minimum Charge is really the minimum and therefore you also need a Timer to limit the Maximum Charge.

I had the a similar issue when using a schedule at home to benefit from a cheap tariff, initially I only setup a profile with a schedule and in the morning I wad at 100%, after some digging around this forum I realised I also needed a timer.

I have a Rolec charger a home, which will just deliver power when the Taycan requests it.

Charging is always controlled by the car, not the charger - unless the charger makes itself unavailable (e.g. charger has a built-in timer). If the charger is available and the vehicle doesn't want to charge, it won't and the charger can't change this.

Profiles are GPS based (and there is a default profile that I have tried unsuccessfully to delete - sometimes it comes back with the German word for default). If you want control over charging (meaning if you want something less than 100% charge) you have to create a profile for the charging location. When you plug in and a profile is active at that location, the minimum charge in the profile tells the vehicle the target charge to achieve immediately. Once that target charge is reached, it will stop charging. Whether or not you also need a timer depends on if you want the battery or interior pre-conditioned for a specific departure time or if you have times where the electric rate is lower.

Thanks. I will create a location-based profile and try that.

Thanks. I will create a location-based profile and try that.

I also had trouble with the profile not working. I set up different profiles, both at home, to charge to 60% and another to 90%. I only use the slow Porsche home charger, as I am not doing large mileages at the moment I found that only once the charger stopped at the point to which I had set it. It either just stopped whenever it felt like it, or else it continued when it should have stopped. From what I am reading here, this may be because there is no GPS most of the time here. Anyway, I have given up on profiles, and either let it run, or stop it when I find appropriate, but I cannot rely on the profile. I also set up a wifi point in my garage to see if the car could connect with that but it cannot, so that's no good either.

Wifi connection doesn’t work in North America. The dealer told me that Porsche hasn‘t enabled it because they want to sell the cellular-based data connection. Not sure if this is the same for you in the UK.

When you are about to plug in the car, you can check the active profile and timer in the charging status window (central control display or the PCM display). If no location-based profile is active, the general profile (the default profile) will be applied (if checked / enabled). If that one is disabled the car will just charge to 100% when you plug in (same as if you checked direct charge). I don't know what the car would say though - maybe no profiles active...

 

[NormF]

Thanks. That might be the reason. The 85% profile selected was for a different GPS location, so maybe was overridden by the general one. This Porsche software leaves something to be desired. This should not be complicated!

Issue solved. You need to create a location-based profile (GPS) with the charging % you wish, and optimized charging. If you select a profile for another location, even if it is the only one ticked, it will not be used. Car will charge to 100%. Not sure I understand the design logic. Use of a Timer will also accomplish the same result, especially if you want the car to heat or cool and charge by a certain time.

Profiles are GPS based (and there is a default profile that I have tried unsuccessfully to delete - sometimes it comes back with the German word for default). If you want control over charging (meaning if you want something less than 100% charge) you have to create a profile for the charging location.

Not entirely true - that default profile you’ve been trying to delete is the key to simple limited charging. It’s not location based (you’re right that any other ones created are, but the default one isn’t).
Just set the default (or General I think it’s called) profile minimum charge to 85% and you’re good to go. Yes, I know it makes it sound like a minimum of 85% and it might charge to 100%, but it doesn’t. And it applies at all locations, unless overridden by another profile.
That’s by far the simplest way to limit the charge level.

Yes - thanks for the correction. You CAN disable the general profile though - then, in the absence of any active profiles, I think (but am not certain) the car will act as if direct charging is enabled.
