Tip: How to Start a Session with an RFID Card

Greenlots RFID Card

Method to Attempt if Charging Station is Offline

Sometimes a public EV charging station will have power but it is not communicating with the service provider’s network. This could prevent you from being able to initiate a charge using the mobile app associated with that network. If the station is offline, then the signal to authorize a session may not be able to reach the unit from the charging service provider.

For example, the screen image above is a message on the Greenlots app that displayed when I tapped the “Start Charge” button for a Pepco owned and operated station that was showing as “offline” in the Greenlots app.

When this happens, you can call call customer support and see if they can help. Sometimes they are able to reach the station and either reset it or help you initiate a charge from their end.

When all else fails, it is worth trying to use an RFID card instead of the app. Sometimes the card will be successful in starting the charging session even if the unit appears to be offline.

You may need to order an RFID card from the various charging networks in order to be prepared for this contingency. In some cases, there may be a small fee for the card.

Hope this tip is useful. Enjoy your travels and happy charging!
