Calibration inaccurate
Has anything been changed on the Opel Mokka E 46kwh model in the last 2 weeks?
My calibration has been way off since then.
Normally the value of 176wh/km was almost perfect.
Now it is about 10% off.
If I cleared the calibration and drove with a high SOC, I got about 180wh/km.
But when the SOC gets lower, the calibration goes way up. Even over 200+
(Since 2025 there is a new Mokka E 46kwh with optimized engine and a 50kwh model, maybe there is a issue?)
Also i have noticed when unlocking my phone and checking ABRP the resulting recorded drive is broken.
- Where does this happen?
- ABRP version number (found at bottom of settings menu)

Thank you for reporting! I have been looking at your drives for the last weeks and re-run them through our calibration, but I cannot see any particular issues with the data or the calibration. We also have not changed the Mokka E recently.
As the calibration is not perfect (or rather our model does not capture everything in the physical reality) the ref consumption number does vary a little bit on different drives. 176→180 is not unusual. Going above 200 sounds like an issue, can you tell me the date of a drive when this happened?

My Tour on April 5th was the worst.
My Drives an April 10th are also defective.
This happens when i unlock my phone and look at the live data while driving with Android Auto.

OK, we will check those. Can you describe exactly what you see happening when you unlock your phone? Does the reference consumption jump just then?

When unlocking the phone nothing special happens.
But the recorded drives are corrupt.
Examples:
March 25
April 10, 11
The consumption did not jump in these moments.

I checked the April 5 drives and the reference calibration is stable around 179 Wh/km. Comparing to your actual drive the model estimate seems to match well. Did the plans you made not match the actual consumption? Can you give us some more detail (if you remember)?

I know I calculated that I should arrive at the charger with ~25% SOC while I arrived with 18%.
This gave me a bit of anxiety because normally I would plan with much less SOC. Most of the time I try to arrive at the charger with just under 10%.
That would have been rather risky that day.
It was just because ABRP is normally so extremely good at predicting that I was wondering what was going on.
When I looked at the calibrated consumption it said 194wh/km.
On the way back and the following days the problem was very similar, it stated too high compared to usual.
Currently it still says 183wh/km as calibrated consumption.
That's not so far away from 176 - but still.
Normally, ABRP was right down to the percent for me and my driving style.
I'm now also running my battery empty several times in city traffic and slowly charging it up - maybe the SOH has changed a bit too?
Could that also have an effect on the reference consumption?
But as it currently stands, the calculated energy content of the battery (by me) is ~95% of the factory specification, which is also in line with the SOH of 95%.

It could be the actual capacity of your battery declining slightly yes.
About the broken MyDrives on e.g. the 10th, we can see that the latest position for the first minute of the drive was from ~13.00 that day in the city southwards you were driving to later. Could it be that you drove without ABRP when driving north during the day? We do not see any data for that.

Okay, I'll keep watching to see where the consumption goes.
10% BMS decalibration would be strange.
But everything is approaching normal values again.
Maybe the wind was just blowing a differently way than expected =D
Regarding the defective MyDrives, the problem is due to the opening of abrp on my phone.
To reproduce this problem, I do the following:
Start ABRP in the car only.
Drive.
While driving, unlock the phone, switch to abrp on the phone and view the live data.
This is the point where the data recording stops until I restart abrp completely.

Ah - how do you notice the recording not working? Does live data in while driving also stop working for the rest of the trip? Can you give an example date/time of where you did open the phone and recording stopped?

Now I see what you mean with recording stopping. We have a fix for this which will be out as hotfix build 3333 (should be installed automatically in an hour or so).
Thank you for reporting both issues!

Thank you for fixing this :)

It’s not fully fixed.
Look at my last drive, while the SOC is correctly recorded, the position is not.
My car is standing a few km away :)
This is where i unlocked my phone and started abrp on it.

I drove to work today with ABRP only open on Android Auto - nothing recorded in MyDrives.
