Battery Charger Hybrid/EV System Discharge Time Too Long
The battery charger system DC-link discharge time is longer than calibrated. Indicates discharge resistor failure or capacitor leakage.
Affected components
- Battery charger discharge circuit
- Dc link capacitor
Common causes
- High likelihood: Discharge resistor open
- Medium likelihood: Capacitor leakage
Possible symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
Diagnostic notes
- The malfunction indicator lamp may illuminate
- Reduced-power or limp mode may occur
