The 12V auxiliary battery in our Niro has died twice, so I decided to dig back into OVMS to see if it could shed any light on what is going on with the battery. I’ve installed the AuxBatMon plugin to log battery parameters and I have questions…
The module is running: 3.3.003/ota_1/main (build idf v3.3.4-848-g1ff5e24b1b Sep 3 2022 11:32:12) — is this really the latest stable version?
Here’s what I’m seeing:
My questions:
What is the source of the current value? Is it being reported by the vehicle? I’m puzzled by it remaining at a high constant value even after the charger appears to have shut down.
Similarly with the charger and environmental temperature values — it seems add that they are mostly constant.
If there is anyone out there with a Niro / Kona, I’d be curious to know what the behavior of your auxiliary battery looks like.
