Possible Causes
Overheated terminals or contactor contacts, Failing power supply components, Melted insulation on internal wiring, Damaged Type 2 connector from repeated overloads
How to Fix / Troubleshooting
Safety first: Immediately stop charging and turn OFF the breaker. Do not ignore burning smells.
- Visual inspection (power OFF): Remove the cover and look for discoloration, soot, or melted plastic on terminals, contactor, and wiring.
- Check cable and plug: Inspect the entire length of the cable and the plug for soft spots or deformation.
- Do not reuse damaged parts: Replace any component showing signs of overheating rather than attempting to repair it.
Because burning smells indicate a fire risk, have the charger inspected and tested by a qualified technician before returning it to service.
