Charger will not start charging; vehicle shows ‘Charging Error’ and Megear unit displays E01 shortly after plug-in.

Safety first: Disconnect the Megear charger from the wall outlet or turn off the dedicated breaker before opening or handling the unit. Never work on the charger while it is energized.

• 1. Power-cycle the system:
  • Unplug the Megear EVSE from the wall (or switch off the breaker).
  • Unplug the J1772 connector from the vehicle.
  • Wait 2–3 minutes, then reconnect power and plug into the vehicle again to see if E01 clears.
• 2. Inspect the J1772 connector:
  • Check the small control pilot pin (usually the thin pin) for bending, corrosion, or contamination.
  • Clean light debris with a soft, dry brush. Do not use metal tools that can damage the pins.
  • If pins are heavily corroded or loose, the cable assembly should be replaced.
• 3. Check cable strain and damage:
  • Run your hand along the Megear charge cable and look for kinks, cuts, or crushed sections.
  • If the cable jacket is cut or you can see copper conductors, stop using the charger immediately and replace the cable assembly.
• 4. Internal wiring check (advanced):
  • With power disconnected, remove the Megear charger housing screws.
  • Verify that the pilot wire connection from the main control board to the cable harness is firmly seated and not burnt or loose.
  • If the connector is damaged or the board shows burn marks, the main control board or cable harness must be replaced.
• 5. Test with another EV (if available):
  • If E01 appears with multiple vehicles, the fault is likely in the charger.
  • If it only appears with one vehicle, the issue may be with the car’s charge port.

If E01 persists after these checks, discontinue use and contact a qualified EVSE technician or Megear support.
