Description
The battery management system (BMS) detects that it is taking too long to reach the target precharge voltage and prevents packs contactors from closing. This indicates that the voltage on the DC link bus rose more slowly than expected.
Potential Impact
Inability to charge, drive, or support the low voltage (LV) system
Set Condition
The BMS detects that the voltage on the DC link bus is rising slower than it should be. Alert log signal data provides information on the specific condition(s) detected.
Clear Condition
The BMS detects that the condition clears.
