Battery Charger Coupler Lock Control Circuit Performance
The battery charger coupler lock control circuit reports a control circuit performance condition. The on-board charger negotiates voltage, current and safety with the EVSE; a fault interrupts charging or limits it to AC slow-charge despite a DC fast charger being attached.
Affected components
- Battery charger coupler lock actuator
- Wiring harness
- Bms
Common causes
- High likelihood: Actuator response slow
- Medium likelihood: High-resistance contact
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
