Yes I didn’t realise this and to be fair I don’t think this is how it should be. Everything runs off the 12v battery, what’s the point of having 20% SOC if you can’t turn the lights on to see where you’re going
It was the line from the manual you quoted that I was trying to get my head round.
“Note: When the system detects a fault/vehicle start/charging with an external device, it will automatically exit the 12V battery automatic charging function.”
The bit that says charging with an external device is not particularly clear. Is it referring to the HV system and does that mean whilst charging, or does simply plugging the cable in waiting to charge count. Or does it mean an external 12v charger on the LV system so it’s not charging from two sources.
I think in my case it’s just me not realising the limitation of the system and being forced to push it to the limit due to my shifts. Hopefully a charge by the dealer will get it back and then I’ll fit a monitor that I’ve got sitting in the garage that sends me a message when the voltage drops, and just keep on top of it.
