Hello,
I need help with this customer issue:
I am digging into battery failure modes and discovered that I needed to change a few settings to prevent our drones from falling out of the sky from an under voltage cutoff event.
I set:
-
- CELL_TERM = 1
- Term Min Cell V change to 3100mV
- Term voltage change to 12400mV
This is correctly causing the % remaining to go to 0 and prevent a pack with a bad cell from cutting off in the air.
But, I am seeing this same behavior on some packs with good cells. If you look at these logs, you'll see that the voltage did not dip low enough to cause the Cell Term event but the % remaining drops like a rock.
When I hook these packs up to the Battery Management Studio after the flight, they show 0% remaining, 15V+, and true remaining Q of 1500mAh+.
Any ideas about this would be helpful.
I have plenty of other data I can share offline (flight data, srec, etc)
Regards,
Ryan B.
