Description
The vehicle controller detects that precharging the high voltage (HV) DC bus may be unsuccessful, which may lead to the inability to close the HV contactors and a complete loss of vehicle power. Charging vehicles with GB (charging standard used in China) charge ports requires opening and closing the HV contactors.
Potential Impact
If GB DC charging is attempted, the charge session may fail, the HV contactors may not close again, and there may be a complete loss of LV power.
Set Condition
The vehicle controller detects that precharging the HV DC bus may be unsuccessful.
Clear Condition
The vehicle controller no longer detects that precharging the HV DC bus may be unsuccessful.
