OBD to track Battery SOH?

[Daniel]

Does it work?
I’m interested in this as I use BimmerFlow now eflow …

Should have read the complete thread, no for the moment

For the moment it does not work, no connection possible, concerning electric data, neither with Car scanner nor eFlow

I just linked Tronity, though it stated it was Porsche Macan compatible, and the link seems successful … no data in dashboard

Sorry
Actually it was a private message between a Taycan forum member , Johann55, and myself.
I'll try to summarize it.

Teslabjorn from Norway recently tested Audi Q6 etron, and managed to connect Car Scanner (with connection vehicle profile VW MEB ID.4), maybe that will work in Macan EV?


If setting Carscanner connection with this VW profile, the information is very partial and disorganized, with transcription errors, particularly regarding the scales.
However, we can draw some values from it, for my Macan:

Maximum energy content of the traction battery: 94350 Wh
Maximum Energy Content of the Traction Battery (according to VW EV forums) is the rough estimation of the SOH and should be measured at 20-25 C.

My battery temp was 12 ° , and if nominal capacity is 95 , my SoH is 94.35/95 =99.3% ...... maybe


HV battery energy content : 47900 Wh SoC of my Macan , 55% on the PCM

DC battery voltage : 2704 v This value divided by 4 corresponds approximately to the voltage of a 700 - 800 v battery.
I tried charging at the Tesla supercharger not far from my house, this value went down to 1400 , because of the 800 to 400v split of the Macan ?


Some PCM Carplay view of Car Scanner:

While charging in Tesla station

last minute from Johann:
as for Max Energy Content - I found VW forum topic (very long):

Thanks
I just tried it. My car was at 61% soc and I got the following:
All with car scanner, and the Macan name is under the WV

As @ThomasDK did, we can now select Macan EV in Car Scanner setting list.
Result is not awesome ....

Any updates on this I found my OBD dongle, where is the port on the Macan located?

EDIT:
Found the port same as Audi …

Not great it reports 94200 battery capacity but if I calculate with actual energy content and percentage it’s more like 86kwh, granted 14C but still (46% percent of charge indicated)

Hello, I was able to connect an OBD dongle to the port with Car scanner and got the same page as Yves.

but the readable information is so low! Is there any other app or way to read more?

brand new Macan 4S it is reporting 97.45kWh as max capacity.

 

[Yves]

Wow 97kwh max energy content that is cool!

 

[lolli]

Wow 97kwh max energy content that is cool!

yes! It’s interesting!
Actually next time I will charge it to 100% I will verify if the HV battery content is the same as the Maximum energy value.

Which OBD scanner are you guys using? And/or which software?

We are using CarScanner. In my case, it’s last version on Google Play store
