Possible Causes

Shorted output wiring inside Nissan EVSE, Internal failure of main contactor contacts, Control board misreporting pilot current to vehicle, Vehicle drawing more current than EVSE rating

How to Fix / Troubleshooting

Safety first: Overcurrent conditions can cause overheating and fire. Turn OFF the breaker immediately if you smell burning or see smoke.

  • Check breaker size: Verify the EVSE is on the correct breaker size as per Nissan installation instructions. An undersized breaker may trip but should not cause E07 alone.
  • Inspect cable and connector: Look for melted plastic, discoloration, or hot spots on the Nissan connector and cable. If present, discontinue use and replace the cable assembly.
  • Internal wiring check: With power OFF, open the EVSE and inspect the output wiring from the contactor to the cable terminals. Tighten any loose screws and look for signs of arcing.
  • Test with another vehicle (if possible): If E07 only occurs with one vehicle, the car may be requesting excessive current due to an onboard charger fault. Consult a Nissan EV dealer.

Persistent E07 with normal wiring and multiple vehicles indicates a likely control board or current sensor failure. Professional service is recommended.
