Possible Causes

Worn or loose J1772 contact pins, Corroded connector contacts, Undersized or damaged output cable, Loose crimp inside handle

How to Fix / Troubleshooting

Safety first: Stop charging immediately if you notice excessive heat or burning smell. Allow components to cool before handling.

  • 1. Visual inspection: Check the J1772 handle for discoloration, melted plastic, or deformation. Inspect the cable near the handle for soft spots or bulges.
  • 2. Clean contacts: If no severe damage is visible, clean the connector pins with electrical contact cleaner and a soft brush. Do not use abrasive tools.
  • 3. Check vehicle inlet: Inspect the vehicle’s charge port for dirt or bent pins that could cause poor contact.
  • 4. Reduce current (if configurable): Temporarily lower the EvoCharge maximum current setting and observe if heating is reduced.
  • 5. Replace cable/handle assembly: If overheating persists or any damage is visible, replace the entire EvoCharge J1772 cable and handle assembly. Internal crimps and contacts are not field-serviceable.

Continued use of an overheating connector is a fire hazard and can damage the vehicle inlet.
