Possible Causes
Combined RCD sensitivity with internal RCM, Leakage current from vehicle, Shared circuit with other loads, Incorrect neutral-ground bonding in subpanel
How to Fix / Troubleshooting
Safety first: Repeated tripping may indicate a real fault. Do not bypass safety devices.
- Dedicated circuit: Ensure the Autel charger is on a dedicated circuit without other loads.
- RCD type: Verify the upstream RCD type and rating match Autel’s recommendations. Some chargers require specific RCD types (e.g., Type A with DC detection in charger).
- Test with another EV: If possible, charge a different vehicle to see if tripping persists.
- Panel inspection: Have an electrician check for improper neutral-ground bonds in subpanels and correct any wiring errors.
- Measure leakage (qualified only): A technician can measure leakage current during charging to determine if the vehicle or charger is causing excessive leakage.
