Sorry if this has been discussed before but I had my 12v battery die while OVMS was plugged-in.
I've not had OVMS plugged-in for ages (not much need during lockdown!) but we've just gone away for a week and it happened then after only one full day of inactivity.
This has happened before and the common theme then and now is that the car was seemingly left unlocked.
The e-Niro's battery saver module is supposed to kick in of course but I don't see how the voltage could drop so much in one day anyway. I do have the ABRP script installed now so I imagine that could make a difference?
You can see from the screenshots attached that my notifications show what happened.
- August 19th: Drops 1.8V in only 32 minutes. e-Niro's battery saver then kicks in and restores it.
- August 20th (car was unlocked): I woke up to all the notifications where it dropped as low as 4.8v. Battery saver obviously did nothing as when I got to the car it was dead.
So, my question is:
Does the module not 'sleep' properly if the car is unlocked? Could that be why the battery was drained so quickly? Is there any way to get around that?
I'm making a video about it so I'd like to get my facts straight first before I jump to conclusions!
