Understanding the Charging Cycle (OCPP Status)

The status table offers a timeline of the charger's lifecycle, including stages such as Available, Preparing, In Use, Suspended (EV/EVSE), Finishing, Unavailable, and Faulted. These statuses are defined in the Open Charge Point Protocol (OCPP) specification, ensuring they are standardized and universally applicable across systems.

• Available: This is a working charger without a vehicle plugged in.
• Preparing: When a vehicle plugs into a working charger, it goes into Preparing state. An alert on Preparing would fire as soon as the vehicle is plugged in and the initial communications between EV and charger are completed.
• Charging: The charger is currently in session.
• Suspended EV: This state means the vehicle has stopped the charging session. Typically, this happens when the battery is full. Alerts about this state can help troubleshoot if the vehicle stops charging unexpectedly.
• Suspended EVSE: This means the charger (EVSE) has ended the session. This can be normal, such as when the session ends after reaching set battery targets or due to load management policies that stop charging before peak times.
• Reserved: When a connector is reserved for a specific user and will reject any attempt to start a transaction for anyone else. 
• Unavailable: The charger is NOT able to perform a charging session due to error or network connectivity issues.
• Faulted: When a charger has an issue that prevents it from dispensing energy.
