How to Fix / Troubleshooting
Safety first: If you notice heat or burning smell at the plug, stop using the charger immediately.
- Step 1 – Observe pattern: Note whether dropouts occur at high current, high ambient temperature, or only with a specific vehicle or cable.
- Step 2 – Inspect plug and socket: After a charging stop, carefully touch (without force) the plug and socket area. If very hot, there may be poor contact. Look for discoloration or deformation.
- Step 3 – Tighten socket terminals: With power OFF, open the charger and tighten the socket outlet terminals and CP/PP connections.
- Step 4 – Disable remote control (test): Temporarily disconnect the charger from the network or disable smart control to rule out remote stop commands.
- Step 5 – Monitor logs: Use the Alfen interface to review session logs for hidden warnings (temperature, current limit).
- When to call a technician: Persistent unexplained dropouts require professional testing of contactor, socket, and temperature sensors.
