List of error messages
Message
Description
"EXT_Emergency_Stop"
Emergency Stop pushbutton has been activated
"ERR Vout_at_start"
Abnormal output voltage at charger start up
"Out_Pwr_Switch_Fail."
Defective Charger DC output contactor
"Can_Data_invalid"
Incorrect data frame sent by the vehicle on CAN
Vehicle fails to update output current request when
charging starts
"Can_Frame_absent"
No CAN communication
"ShortCircuit"
2 cases
- Output current above Imax.
- Output current above 5 amps during insulation test.
"OverVoltage"
Charger output voltage exceeds maximum voltage limit
"ChargerOverHeating"
Cooling defect. Internal power modules have reached
the maximum permitted operating temperature
"Over Limit I"
The vehicle requires too high a current according to the
start of charging calculation.
"PSU Absent"
No response from power supervisor (internal fault)
"PSU Timeout Change"
Power supervisor timeout during state transition (in-
ternal fault)
"PSU bad state"
Power supervisor goes into incoherent state (internal
fault)
"Connector_Lock"
CHAdeMO plug locking coil defect.
"BatteryIncompatib."
Battery voltage range not suitable for the charger
"BatteryMalfunction"
Vehicle battery fault:
- No CAN communication at charge start-up.
- Incorrect current or voltage data.
- Abnormal voltage at charge start-up.
"ChargingStopCtl"
Charge start-up denied (CAN or physical i/o line).
"VehicleShiftPosition"
Gearshift is not in neutral (vehicle fault)
"VehicleOtherFaults"
Vehicle fault. Check vehicle supervisor.
"BatteryOverVoltage"
Overvoltage detected by the vehicle.
"BatteryUnderVoltage"
Too low a voltage detected by the vehicle.
"BatteryCurrentDiff."
Current measurements mismatch from vehicle mea-
surement and charger CAN data, detected by the ve-
hicle.
"HighBatteryTemp."
Battery overheating detected by the vehicle.
"VoltageDifferential"
Voltage measurements do not match vehicle measure-
ments and charger CAN data, detected by the vehicle.
"InsulationFailure"
Earth fault current detected by charger
"ChargerMalfunction"
During battery charging
- Charger power supervisor (not CCU) stops charge, af-
ter detecting output overvoltage.
- Charge aborted by pressing “STOP” button.
"PSU ERROR ARU"
Software emergency stop requested by the power su-
pervisor (internal).
