SOC Discrepancy with KGM Torres EVX Using OBD

Questions

Hello ABRP Team,

I’m currently using ABRP with my KGM Torres EVX via an OBD connection. I’ve noticed a consistent 2% discrepancy between the State of Charge (SOC) shown on the vehicle’s dashboard and the value reported in the ABRP app.

It would be incredibly helpful if you could either:

* Implement a manual SOC correction/offset feature, or

* Review and refine the PID mappings for the KGM Torres EVX to improve SOC accuracy.

I really appreciate the work you’re doing — ABRP is a fantastic tool and this small improvement would make it even better for EV owners like myself.

Thank you!

    Hi @HAKAN YILDIRIM,

    Sorry to keep you waiting!

    This is because we get the BMS SoC, not the one shown on the cluster.

    The BMS SoC tells us more about the remaining energy than the one shown on the cluster.

    You can, however, use the OBD PID Editor to implement an offset. However, please be aware that this could currently have weird side effects. Depending on what you do, you can end up with more than 100% or less than 0%.
