Charging cable gets unusually warm during charging, especially near the plug or strain relief, but no error code is shown.

Safety first: Overheating can lead to fire. If the plug or cable is too hot to touch, stop charging immediately and isolate power.

• 1. Stop charging:
  • End the charging session via vehicle or charger controls.
  • Unplug the connector and allow it to cool.
• 2. Inspect for damage:
  • Look for discoloration, melting, or deformation on the plug, socket, and cable.
• 3. Check internal terminals:
  • With power off, open the charger and inspect the output terminals and contactor connections.
  • Retighten any loose screws to specified torque.
• 4. Reduce current temporarily:
  • If your Heidelberg model allows, lower the maximum charging current in settings and monitor temperature.
• 5. Replace worn components:
  • If contacts are visibly damaged or overheating persists, replace the tethered cable assembly or Type 2 plug with Heidelberg‑approved parts.
