Autel Maxicharger AC Wallbox users occasionally encounter charging interruptions. This guide addresses common scenarios where an Autel charge is suspended by the charger, providing potential causes and troubleshooting steps.
Common Autel Charger Suspension Scenarios
Several situations can lead to a suspended Autel charge. Let’s explore some frequent occurrences:
Scenario 1: LED On, Charging Stopped, Restart Not Allowed, App Shows Failure
This scenario often indicates a critical fault detected by the charger. Possible causes include:
- Grid Fault (Overvoltage): Verify grid voltage stability. Continuous overvoltage requires professional electrician intervention.
- Power Grid/Connection Fault (Undervoltage): Check grid voltage and cable length. Excessive voltage drop due to long cables can trigger this fault.
- Power Grid/Cable Connection Problem: Ensure secure wiring terminal connections and power supply. Consult a professional if necessary.
- Grounding Fault: Verify proper PE grounding and cable connection. Seek professional assistance for grounding issues.
- Poor Terminal Contact: Inspect and ensure reliable connection of all terminals.
- Internal Charger Issues: Potential problems include leakage current detection, abnormal voltage, overcurrent, or communication failures. Try removing and reinserting the charging gun or restarting the device. If the problem persists, contact Autel support.
- Vehicle Charging Port Fault: Try removing and reinserting the charging gun or restarting both the charger and the vehicle. If the issue remains, diagnose the vehicle with an Autel diagnostic tool or contact the vehicle manufacturer.
Scenario 2: LED On, Unable to Charge, Restart Requested, App Shows Failure
This situation often points to power grid or connection issues:
- Cable Connection Sequence: Verify the correct connection sequence of L and N cables to the Power Distribution Board (PDB) and the charger. Professional assistance might be required for troubleshooting power grid and line faults.
Scenario 3: Charger Displays “Stop Charging,” App Shows Failure
This indicates a charging process interruption. Possible reasons include:
- Cable Connection Problem: Check if the PDB output terminal is powered on. Consult a professional electrician if needed.
- External Protection Device Activation (RCD/RCBO): Manually reset the RCD and check for short circuits or insulation drops at the input. Persistent faults require professional attention.
Scenario 4: LED On, Unable to Charge, Restart Not Allowed, App Shows Failure
This scenario suggests a software or communication related problem:
- Software Exception: Potential causes include electronic lock failure, Bluetooth communication issues, failed Bluetooth upgrades, or network connectivity problems. Try removing and reinserting the charging gun or restarting the device. Contact Autel support if the issue persists.
Resolving Autel Charger Suspension Issues
While this guide provides general troubleshooting steps, always prioritize safety. Consult a qualified electrician for complex electrical issues. For persistent problems or when in doubt, contact Autel’s technical support team for expert assistance. They can provide specific guidance based on your charger model and error codes.
