BMS_a067_CAC_Imbalance_Limiting
High voltage battery performance limited
What does the BMS_a067_CAC_Imbalance_Limiting alert mean?
The battery management system (BMS) detects that the calculated Amp-hour capacity (CAC) difference between bricks within a single module exceeds the acceptable threshold, which may reduce battery performance.
What you'll see in your Tesla
- High voltage battery performance limited
- OK to drive - Schedule service soon
What triggers it
The BMS detects that the estimated CAC imbalance between the average CAC and the minimum CAC of bricks within a single module exceeds the acceptable threshold.
When it clears
The BMS detects that the estimated CAC imbalance between the average CAC and the minimum CAC of bricks within a single module is within the acceptable threshold.
Potential impact
Battery performance may be limited, which may reduce maximum range and may limit charging performance.
