Alert Information
Battery
critical
<0.01%
Description
The battery management system (BMS) detects conditions that indicate a potential propagating thermal event.
Potential Impact
Indicates rapid temperature rise in conjunction with other critical alerts. Pack may remain inoperable and should be serviced according to proper procedures.
Set Condition
At least one brick under/over voltage alert was recently active, and at least one isolation alert was recently active, and at least one battery monitoring board (BMB) missing (MIA) alert was recently active, and the max thermistor temp exceeds the limit, and the pack temperature gradient (maxTemp - minTemp) exceeds the threshold, and that gradient is increasing at a rate greater than the slop threshold.
Clear Condition
None. This alert clears upon BMS reset.
