Possible Causes
Loose internal connection on main control board, Thermal expansion causing marginal solder joint to open, Intermittent fault in output cable conductors, Overly sensitive upstream RCD or breaker tripping momentarily
How to Fix / Troubleshooting
Safety: Repeated interruptions can stress both charger and vehicle. Identify the cause before continued use.
- Monitor upstream breaker: Check if the circuit breaker or RCD is tripping when the interruption occurs.
- Check cable strain: Ensure the output cable is not under tension or twisted sharply near the charger housing or connector.
- Test on another circuit: Use a different outlet or circuit to rule out supply issues.
- Observe temperature: If interruptions occur only when the unit is hot, internal thermal or solder issues may be present and require professional inspection.
