Charger powers on but will not start charging; no specific error code shown on display

Possible Causes

Dirty or damaged J1772 connector pins, Vehicle not fully in Park or not ready to charge, Weak pilot signal due to cable damage, Software configuration preventing charging (e.g., schedule only)

How to Fix / Troubleshooting

Safety first: Do not force the connector into the vehicle. Turn OFF power before detailed inspection of the cable.

  • Check vehicle status: Ensure the vehicle is in Park and configured to accept AC charging. Some EVs require doors closed or a specific setting.
  • Inspect connector: Examine the EVgo J1772 handle for bent or recessed pins and debris. Clean with a dry, soft brush.
  • Check charging schedule: In the EVgo app or charger menu, verify that no delayed charging schedule is blocking immediate charging.
  • Try another vehicle: If possible, test with a different EV to determine whether the issue is with the charger or the vehicle.

If the charger consistently fails to start with multiple vehicles and no code, an EVgo technician should test the pilot circuit, cable assembly, and control board.
