Possible Causes

Pilot voltage slightly out of spec due to resistor drift, Slow contactor closure timing, Noise on pilot line from nearby equipment, Poor contact in J1772 pins

How to Fix / Troubleshooting

Note: These issues can be subtle and may only affect certain vehicles.

  • Step 1 – Clean connector: Use electrical contact cleaner on the J1772 pins and the vehicle inlet to ensure low-resistance contact.
  • Step 2 – Inspect cable: Check the BougeRV output cable for damage or tight bends near the handle that could affect the pilot conductor.
  • Step 3 – Test with another EV: If the problem only occurs with one vehicle, consult the vehicle manufacturer for compatibility issues.
  • Step 4 – Firmware update: Update the BougeRV charger firmware to the latest version to correct any pilot timing bugs.
  • Step 5 – Board-level repair: If multiple vehicles show errors and cleaning does not help, the pilot generation circuit on the main control board may be drifting and the board should be replaced.
