OCPP / Cloud Backend Communication Error
Symptom
Charger cable is difficult to insert or remove from the vehicle inlet; requires excessive force.
Mechanical Wear or Deformation of Connector
Symptom
Charger cannot be started or stopped from the Autel app, but local control works.
Remote Control / API Command Failure
Symptom
Charger emits a loud humming or buzzing noise during operation, louder than normal transformer hum.
Mechanical Vibration / Magnetic Noise from Contactor or Power Module
Symptom
Charger enclosure or connector emits a burning smell or visible smoke during or after charging.
Overheating / Component Burnout
Symptom
Charger frequently disconnects from Wi-Fi or loses connection to the Autel app; charging may still work locally.
Unstable Wireless Connectivity
Symptom
Charger has no power at all; display is blank and status LEDs are off.
No AC Supply / Internal Power Supply Failure
Symptom
Charger intermittently stops charging without any error code; charging resumes after unplugging and reconnecting.
Intermittent Output Cable or Connector Fault
Symptom
Charger or connector becomes very hot to the touch during normal charging, even at rated current; no error code shown.
Thermal Overstress / High Contact Resistance
Symptom
Charger powers on but the touchscreen or display is blank or unreadable; LEDs may still function.
Display / HMI Module Failure
Symptom
Charger randomly reboots or restarts during charging sessions without showing an error code.
Unstable Internal Power or Firmware Crash
Symptom
Charger scheduling/timer functions do not work correctly; charges at wrong times or ignores schedule.
Scheduling / Time Configuration Fault
Symptom
Charger trips the upstream RCD/GFCI or main breaker as soon as charging starts; no specific charger error code.
Nuisance or Real Ground Fault Tripping Upstream Protection
Symptom
Charger’s built-in cable management hook or holster is loose or broken, causing strain on the cable.
Mechanical Damage to Cable Management Hardware
Symptom
Charging current displayed on the charger or in the app is inaccurate compared to the vehicle or external meter.
Current Measurement Calibration Drift
Symptom
RFID cards are not recognized; tapping the card has no effect, but the charger otherwise works.
RFID Reader Malfunction or Configuration Issue
Symptom
Vehicle shows 'Charging Paused' or 'Unable to Charge' but the charger shows ready; no error code displayed.
Handshake / Communication Mismatch with Vehicle
Symptom
Water or condensation visible inside the charger housing or around the connector; may cause intermittent faults.
Moisture Ingress / Enclosure Sealing Failure
