Alert Information
Battery
critical
<0.01%
Description
Calculated Amp-hour Capacity (CAC) difference of bricks within a module exceeds acceptable threshold. This results in reduced battery performance and limits maximum range. Vehicle enters Battery Management System (BMS) limp mode.
Potential Impact
Maximum charge and discharge current limits and maximum energy available are reduced, causing reduced battery performance and limiting maximum range. BMS limp mode is triggered, with another alert present to indicate this condition.
Set Condition
The estimated imbalance between the average CAC and minimum CAC within a single module exceeds the alert set threshold (CAC imbalance is not within acceptable range)
Clear Condition
The estimated CAC imbalance is under the alert clear threshold (CAC imbalance is within acceptable range)
