BMS_a147 — SW SOC High Ah Error
Full alert identifier: BMS_a147_SW_SOC_High_Ah_Error
Some fields retain information from an earlier alert reference.
Alert description
The Battery Management System (BMS) detects that a state of charge (SOC) by high Ah saturation occurred while SOC saturation was active.
Potential impact
BMS is likely overestimating SOC of some bricks due to incorrect CAC or Coulomb counting.
Set condition
An SOC by Ah saturation of more than 3% occurred while SOC saturation was active.
Clear condition
All bricks have less than 1% SOC by Ah saturation.
