Taycan and Tesla charging

[Slatibartfast]

I know this has been partially covered in other threads, but not as a question for European owners so I need some help please- I about to take delivery of a Tesla model 3 and a Taycan Turbo S. I am looking into either two Porsche connect chargers with a home energy manager to control the charging between the two cars, or two Tesla wall connectors. But I don’t properly understand yet if either of those set ups will work?

Are both cars compatible with each others chargers? And is the two Tesla chargers route a sensible suggestion (it’s certainly less expensive)


I need to have both cars on charge most nights simultaneously and therefore need the chargers to communicate with each other and make sure I don’t trip fuses all night. Anyone with experience of this set up please help!!

I have one Tesla Wall Connector and One Porsche PMCC! I also have the Home Energy Manager, but can not get the HEM to work with the Tesla charger. Both chargers will work on either of the cars just fine. Both Chargers can provide up to 22 kW but neither of the cars can draw more than 11kW. I have enough power to my house on 3 phase so I have not had any problems charging both cars at the same time.

If I would have a choice I would actually go for the Tesla Wall Connectors and wire them to protect the house power. They can be connected to communicate. The PMCC is clumsier and only benefit is that it is “transportable”, but huge and heavy. The other difference is that the Wall Connector is a fixed installation.

Thanks for the advise Peter. Am I right in thinking that one other advantage with the tesla charger is that you have the button on the charger handle to open the cars charger port remotely whereas if you use the Porsche charger you will have to use the app/main screen every time?

Yes, you are quite right. You want the Tesla connector for precisely the reason you have given! It is a real pain having to open up the app or go to the main screen to open the charging port. We have the Taycan and a Model X both on Tesla connectors and charging at the same time on our 3 phase.

But the Porsche charger is made in Germany and looks very well built. The last t charger I had overheated and had to be thrown away after 4 years.

Never thought about that really. I normally have my app open for the car to open and also to drive it. When I come home I have the phone in my pocket, car is still open and I normally tap the charging flap and it opens. It is a very similar gesture as with the Taycan so I seldom use the button on the handle, but you are correct it is easier that way. But I believe the car must be open or at least the phone connected to the car at that point? I have not used the charge port opening in the car or via the app ever to charge at home. At a public charge4 that has happened.

Hello,

I think your key requirement is that the two chargers have to communicate with each other, to limit the combined charging load.

First of all, I would not risk to buy a setup where you don't know beforehand that it will work, because communication even between just one charger and one energy manager units is not something that can be taken for granted: For example, my EM did not want to talk to my Porsche Mobile Connect charger. I know have a different EM (from SMA), but did not bother to recheck if it works now.

Second, coordinating chargers into a "charger grid" seems like an advanced feature. I ended up buying a 22kW Mennekes Amtron, supposedly they support load management over multiple units.

HTH,
Henrik

If you have the Porsche Home Energy Manager, you have the option to add several other chargers (from any manufacturer) by buying additional sensors. Then you can prioritize by three criteria. Either a fixed priority sequence, one where they have priority according to the order in which they started charging or a balanced charge. This will work by allowing each charger to use all the current available (user programmable) by adding solar production (if available) and maximum draw from electrical company and subtracting home consumption. It works like a charm. I have only one charger. Setup is not easy to understand due to extensive instructions not being clear with important details. Had to use a little trial and error to figure it out and several calls to the person that Porsche had assigned to my installation. They visited my house but my trusty electrical installation company that did all my home automation, installed the 30kw/h of solar panels and changed my electrical installation when I bought my house, was hired to do the work. My home installation is 400V three-phase with a 17,2A contracted capacity and 240V per phase. However I can draw up to twice as much and my meter will record the maximum draw 15 minute average, and if I exceed the 17,2A I will have to pay a penalty on the whole months consumption. This penalty can range from 10% to almost 100%. Since I properly configued home-energy manager, I have never even reached the maximum. It throttles the charger and I have seen charging as low as 5kw during a very cloudy day with a lot of energy consumption from my house. Obviously if I charge after midnight, when the reduced rate is in effect, it can charge at the full 11kw (due to the fact that home consumption is drastically reduced compared to daytime). If Porsche makes available the 22kw charger, I must upgrade to a higher rated contract to take advantage of it without paying such a high penalty or only using the full capacity automatically when the solar produces enough.

Thank you for such a clear explanation of the home energy manager. I too have had the Porsche recommended electrician visit and he didn’t even know what it was which means I have no confidence in what he recommended from the beginning.
I had to show him the part and he said he’d look into it.

This is the problem at the moment. The Porsche dealers know very little about the cars and the charging etc. There are far too few persons Trained and informed about EVs. I can understand that fact, but then Porsche needs a helpdesk or some specialist that issues can be escalated to. It is not acceptable that such an expensive consumer item is lacking so much support and information.

How about everybody sends a note to the local Porsche importer when things like lack of information happens. I have done so anytime I have got incorrect or no information from my local dealer. Quite a number of occasions now. I have got contact from Porsche France, so hope things will improve soon.
