Using Car Scanner App to log, understand and diagnose Taycan

[rs38]

yes, there is an accumulated amount of AC charging stored (in kWh), so you can estimated the AC/DC ratio.
I did not find a total amount of energy turnover until now.
But there are also "buckets" of power range statistics in hours in the ECUs. e.g. "-200kw = 3h" which can be DC charging but also regen braking.
With VCDS you can easily explore on you own.

I think @ciaranob would be highly interested in your VCDS findings.

Programming date (HEX) seems to be a bug as this is only the part number

nice find is:

>Calibration date (HEX): 220901
>Calibration date (HEX): 220831
>Calibration date (HEX): 220830

this is the last firmware programming in my case the week where I got WNJ8, so they really struggled with it.

Also it's possible to conclude the car's build date.
e.g. Telematic Unit is quite old, maybe so many errors with it?

>ECU manufacturing date (HEX): 181120

Battery (BMS) fit quite well with build week.

>ECU manufacturing date (HEX): 201126, 1-2 weeks before

the version everyone can read from insides main display.

please post your data as well to compare some versions ans dates

Would you know if the amount of kWh charged at AC and DC is stored in there somewhere? I can not find it in the app at present. Would be interesting to see the impact of different charging patterns would have.

@Scandinavian, did you figure out how to read the AC and DC charging data?

No I have not been able to find this, if it is available??
Sorry can not help with that.

if some of you guys would share VCDS blockmap scans of C6 ECU I could try to reverse even more accurately

@rs38
Any way to view information about the HV heater? It has an internal circuit board. I don't see it listed as ecu on scanner.
Certain HW and SW versions mean the heater should be replaced.

Is anyone still interested in the data pulled from Taycans using Car Scanner? I was curious about the HV Battery State of Health (SoH) on my October 2020 8,750 mile Turbo S. Here’s what I got but no idea if 93.47% is good or bad ?‍

OBDII interface = Vgate iCar Pro via BLE on iOS

Are you following the primary thread on the SoH topic?

No, hadn’t seen that. Thanks for the pointer ?

hello, would you have the PID's that the app is using? Torque Pro uses csv files such as below. it might be easier to start from that csv file to reverse efficiently. I could give a try.

 

[rs38]

the only way to acquire these "PIDs" is sniffing with a Y-cable or be a good digital reverse engineer.
I started like ~10 discussion with potential reversers and explorers promising great expectations in PMs here, never got a single useful result.

thx for answer. yes indeed the y-cable is an option, I will give a try. the other way I was first thinking is to export the csv file from torque Pro (Android) [based on fact that we can import in torque Pro csv files). However, on Car Scanner (on iOS) I did not find the possibility to import/export csv files.

 

[rs38]

feel free to export and share something from Torque.
Carscanner offers export only for custom sensors.

ok I see. I'll do that. in the meantime, I used y-cable and Carscaner. this is summary what I could read for throttle:

 

[Lex Postma]

hello,
There are 2 SOH in our Taycan.
1, compares between de max capacity of the battery and de max 100% car capacity.
example max range battery = nom cap 93,4 KWh
and useable cap by 100% charge taycan = 83,7 KWh (safety margin Porsche) 83,7/93,4 * 100 = SOH 89,61% theoretically.

2. The real SOH of your car.
read with the OBD scanner by 100% charge the real battery capacity ( new car = 83,7).
so 100% charge cap of your car/ max new car * 100= SOH %
Example:
my Taycan 42..000Km 22GTS 78,2/83,7*100 = SOH 93,42%
