This is general guidance based on U.S. Department of Energy AFDC. Actual charger behavior varies by manufacturer and firmware version. Always follow on-screen instructions and contact the charging network if you are unsure. If anything looks or feels unsafe, stop charging and move away from the charger.

Warning

The QR code on the charger is not scanning properly or links to an error page. The QR code may be damaged, faded, or the backend service is down.

Seeing this on the charger right now?

  1. Don't unplug while the charger is active. Wait for the screen to update.
  2. Try stopping and restarting the session from the charging app or RFID card.
  3. If the error persists, move to a different connector or charger if available.

What to do

  1. Try scanning from a different angle or distance
  2. If the code is damaged or faded, try typing the URL shown on the sticker manually
  3. Use the charging network's app directly instead of the QR code
  4. Try an RFID card or contactless payment
