BMS_a065_SW_CAC_Imbalance

The Calculated Amp-hour Capacity (CAC) difference of bricks within a module exceeds the acceptable threshold. This results in reduced battery performance and limits maximum range.

Live incidence rate

<0.01% (Extremely rare)

Vehicle messages

None displayed

Impact

Maximum charge and discharge current limits and maximum energy available are reduced, causing reduced battery performance and reduced maximum range.

Description

The Calculated Amp-hour Capacity (CAC) difference of bricks within a module exceeds the acceptable threshold. This results in reduced battery performance and limits maximum range.

Cause

The estimated imbalance between the average CAC and minimum CAC within a single module exceeds the imbalance threshold.

Clear condition

The estimated imbalance between the average CAC and minimum CAC within a single module is within the acceptable imbalance threshold.
