Minimum Required Error Codes (MREC)

The following tables list the ChargeX proposed Minimum Required Error Codes (MRECs), their descriptions and their functional and responsibility classifications.
Number Error Code Fault Code Description
1. ConnectorLockFailure CX001 Failure to lock or unlock connector on the vehicle side.
2. GroundFailure CX002 Ground fault circuit interrupter has been activated.
3. HighTemperature CX003 High temperature inside the EVSE is derating power delivery.
4. OverCurrentFailure CX004 Over current protection device has tripped.
5. OverVoltage CX005 Input voltage to the vehicle has risen above an acceptable level.
6. UnderVoltage CX006 Input voltage to the vehicle has dropped below an acceptable level.
7. WeakSignal CX007 Wireless communication device reported a weak signal.
8. EmergencyStop CX008 Emergency stop is pressed by the user (required if equipped).
9. AuthorizationTimeout CX009 The user plugs in but fails to authorize a charging session prior to the connection timeout between the vehicle and EVSE.
10. InvalidVehicleMode CX010 The vehicle is in an invalid mode for charging.
11. CableCheckFailure CX011 Failure during the cable check phase. Includes isolation failure
12. PreChargeFailure CX012 The EVSE did not reach the correct pre-charge voltage.
13. NoInternet CX013 The EVSE has no internet connectivity.
14. PilotFault CX014 The control pilot voltage is out of range.
15. PowerLoss CX015 The EVSE is unable to supply any power due to mains failure.
16. EVContactorFault CX016 Contactors fail to open or close on the vehicle side. May also include welding related errors.
17. EVSEContactorFault CX017 Contactors fail to open or close on EVSE’s side. May also include welding related errors.
18. CableOverTempDerate CX018 Temperature of charging cable or connector assembly is too high, resulting in reduced power operation.
19. CableOverTempStop CX019 Temperature of charging cable or connector assembly is too high, resulting in a stopped charging session.
20. PartialInsertion CX020 Cable latch is raised due to incomplete insertion into the vehicle charging port.
21. CapacitanceFault CX021 An Isolation Monitoring Device tripped due to high capacitance during active charging.
22. ResistanceFault CX022 An Isolation Monitoring Device tripped due to low resistance to the chassis during active charging.
23. ProximityFault CX023 The proximity voltage is out of range.
24. ConnectorVoltageHigh CX024 The output voltage of EVSE is high before charging starts or after charging ends.
25. BrokenLatch CX025 The latch on the connector is broken.
26. CutCable CX026 The output cable has been severed from the EVSE.
