Possible Causes
Loose CP or PP contact in Type 2 socket, Damaged tethered cable, Temperature sensor triggering derating, Vibration causing intermittent contactor drop-out
How to Fix / Troubleshooting
Safety first: De-energize before internal inspection.
- Check plug fit: Ensure the Type 2 plug fits snugly and locks properly. Excessive play can cause intermittent CP contact.
- Inspect cable: Flex the tethered cable gently along its length while monitoring charging; if interruptions correlate, replace the cable.
- Socket contacts: Inspect the CP and PP contacts in the Mennekes socket for wear or loss of spring tension. Replace the socket insert if necessary.
- Temperature monitoring: Review logs (if available) for thermal derating events. Improve ventilation or reduce configured current if the unit is regularly overheating.
