I connect my car via live data and it starts accurate SoC. Within 15 min it starts to creep upward at current SoC not matching actual. Eventually it ends up as much as 30% different. So much so destination % is higher than actual as I get close to destination.
I started to use live data from OBD BLE instead of Tronity and it shows me about 10% less SoC than it is. The ID.3 infotainment shows 100% SoC, Tronity says 100% ABRP says 90% SoC from OBD BLE. It's not useful for scheduling long trip and required charging.
Sorry for the lack of response on this thread. Are you still seeing this issue?
The SoC detected with an OBDII dongle is different from the one shown in the car.
The difference is about 7%.
In particular, when the car shows 80%, ABRP displays 73% and when the car shows 70% ABRP displays 63%.
I cannot see that you have any car linked for live data currently. What live data source were/are you using?
How wrong are the values? Could you give some examples on what's reported vs what's accurate?
Your calibrated reference consumption seems very high however. Here's how you can have it reset and restart the calibration: www.iternio.com/faq?questionId=d039f2d7-ee7d-4e26-ade7-bd48f17c4ea3&appDefId=14c92d28-031e-7910-c9a8-a670011e062d
It was off by more than 30%. Indication was correct at the first charging stop and then it went haywire on the 2nd. The BMW app also showed wrong values. I unlinked the car, uninstalled and re-installed ABPR. I need to try and re-connect to the OBDII Bluetooth dongle, but it was failing before I reinstalled ABPR last night, and I have not had a chance to try again. I am weary doing it before I get home tonight, as I don’t want the BMW app to show wrong values again also. Once I unlinked the car it shows correct again.
As we do not have display SoC for MEB cars, we calculate it based on BMS SoC. Could be that the 58kWh variant has a different buffer here. Is it the same SoC different all along the whole SoC range? Then we can just add a different profile for the 58kWh variant.
I am not sure about the original poster's problem, but I have noticed the displayed SoC from ABRP to differ from the car like this:
Car 80%, ABRP 81%
Car 20%, ABRP 21%
(Id3 58 kWh)
Then I noticed the other day that my car showed 8% and ABRP showed 5%. This wasn't a one off, I saw similar differences when below say ~10-15% SoC... Usually I stay above 10%, so perhaps it has been like that always.
Another update. Today I checked a little bit more while driving. The transition didn't happen exactly at the same time for the Car numbers and the ABRP numbers, but this is roughly the correlation according to an observation today.
Car 10%, ABRP 9%
Car 9%, ABRP 8%
Car 8%, ABRP 7%
Car 7%, ABRP 6%
Car 6%, ABRP 5%
Car 5%, ABRP 4%
Car 4%, ABRP 3%
Have you made sure that live SoC is enabled in settings so that ABRP is not starting out from a manually entered value?
The button to the right of the SoC input in settings should be filled blue, alternatively you can just toggle on 'automatic settings' at the top of the settings menu to enable live SoC, reference consumption etc.
