OTA Software Update (July 17, 2023)!

[WasserGKuehlt]

OTA authentication and Plug & Charge authentication do not share anything. Plug & Charge uses a contract certificate from your mobility provider, which mostly is the Porsche Charging contract for Taycan owners, but also could be any other. A detailed description of the Plug & Charge process can be found here: https://www.switch-ev.com/blog/basics-of-plug-and-charge

Thanks for sharing the article, it was a good read. It is, however, fairly high level/covers the fundamentals but does not say much about the issuance of certificates to the vehicle (which is what we were talking about earlier) - it explicitly says that aspect is not defined in the standard. I have not yet read the linked article on VDE application guide, which promises to cover those details.

(edit) lol, never mind - they want $300 for the pdf.. so we’re back where we started, then.

@WasserGKuehlt The charging certificate is issued by the mobility service provider (e.g. Porsche Charging Service) and installed to the Taycan via a compatible charging station when first using the RFID card/app. When it is expired, the charging card has to be used again to get a new charging certificate issued and installed.

If this does not answer your question, please clarify what exactly you want to know. Thanks.

Can a Taycan equipped with Plug and Charge software and hardware potentially have the ability to use Plug and Charge from a non-Porsche mobility service provider:
a -instead of, or
b - in addition to the Porsche mobility service provider?

In theory it should. It is always instead of, as long as certificates are only handled in the EV with the current ISO15118-2 standard. The upcoming version ISO15118-20 allows to store up to 5 certificates in the OBC and then the user could either choose or it could be auto selected by best price (in theory).

BMW goes a different route and already support multiple certificates. But there you have to register your charging services online with your BMW account, and then you can select any of them before charging and it will be installed onto the OBC over the air.

I had a power Steering update saturday

Could you also send a photo of the Software Version screen.... (where it shows all the versions, hardware, software, PCM, text, etc...)?

(my23 4ct, built Nov 2022; no dealer visits, so any updates were delivered OTA)

Don't get your hopes up. The PCM version information screen seems to mostly show versions involving, well, the PCM. At least according to the release notes, that was not what was updated here.

Maybe you can find a difference in the myriad of versions shown in the engineering menu (I'm not totally sure what they are, but it's plausible).

I think I had the same, but I forgot to take a picture of it.
This is the first OTA update I`ve got since the big up-date last year.

Maybe Porsche has solved their software / OTA issues?

I made an observation earlier this year. Shortly before my annual renewal date of the Porsche charging service, both plug'n charge as well as my RFID card stopped working. Use of the app, was the only option for charging (I use Ionity for 95 % of my longer trips).

After about 10 days, I received an new RFID-card from Porsche. This worked fine, but plug'n charge would still not function. I had to do a complete reset of the car/PCM to factory settings, log in with my user account, and then visit an Ionity station in order to activate plug'n charge again (this is how a new certificate gets installed).

Seems to me, that Porsche still has some steps to complete when it comes to certificate handling.

Oof. They really should add some certificate reset action somewhere deep in a menu instead.

I uses it and it worked fine.The update was about about optimizing the direct charging software

I didn't find this in the thread, but I notice that now, after a Direct Charge, the Direct Charge option is turned off for the next charge. I had a problem before that, when i did a Direct Charge, that setting stayed on, and I then charged to 100% at home (when I wanted 85%).
That is now fixed for me, as selecting Direct Charge only lasts for one chage session.

Nice feature enhancement IMO. I still have not gotten the notification about this OTA update in my car yet though :-(

Oh wow, that just happened to me. First and only time I've used Direct Charge, too.

Nice to know that had I waited for a day or two, it would not have happened. ? But I'm pretty confident that charging it to 100% once won't ruin my battery.

What is your Model Year? Apparently the 2020 MY Taycans are not getting this OTA and may have to go to the Dealer.

I have a 2022 GTS that also has not yet had the OTA update... (although several map updates recently )
