Customer Journey

The user initiates the charger pairing process in the app

The journey starts in when the user navigates to the charger pairing section within the App. When the user opens this screen, the App generates a unique activation code which is then prominently displayed in the User Interface for the user to note.

The user enters the the Pairing Code in CPO's UI

With the activation code at hand, the user then transitions to the Charge Point Operator's platform.

Here, within the charger settings, the user can initiate the pairing process, and is prompted to input the activation code as showcased in the SCSP's app.

Once successful, the user sees a confirmation that the pairing process has succeeded and from that moment onwards, charger data will be transmitted to the Jedlix App.

The user sees that the charger is successfully paired in the app

The Jedlix app confirms that the charger is added to the charging location and can be used for smart charging.

Finally the dashboard in the app shows a status that indicates that the app is waiting for a session to take place on the charger.

The user unpairs the charger

if the user decides to stop the service they can navigate to either the App or CPO interface.

Technical Details

Sequence diagram

Step 1: User Initiates the Charger Pairing Process in the App

The user accesses a specialized section in the app to begin the charger pairing process. A unique Pairing Code is generated and displayed prominently to the user as soon as they navigate to this section. An information button is available to guide the user on how to utilize the Pairing Code.

The code will expire after a reasonable period of inactivity by the user. The user can request a new code if needed

Step 2: User Enters the Pairing Code in CPO's UI

The user transitions to the CPO platform and enters the provided Pairing Code in the specified field within the CPO’s user interface.

The CPO’s user interface validates the pattern (REGEX) of the entered Pairing Code and provides immediate feedback to the user:

If successful, it indicates that the Pairing Code has been accurately entered and submitted.
If unsuccessful, an error message is displayed, specifying the incorrect format and suggesting the user try again.

Step 3: Pairing in Progress

Subsequently, the CPO platform forwards the entered Pairing Code and the corresponding EVSE object to Jedlix for verification.

Depending on your integration, this pairing code can be provided this in two formats:

When you intend to use the OCPP 2.0 formatted data exchange and controls, you should use the 3-tier model for pairing and unpairing.
When you intend to use the OCPI 2.2 data exchange, the 2-tier model for pairing and unpairing should be utilised.

Step 4: Processing of Charging Station details

If the Pairing Code is processed successfully and the received Charging Station or EVSE object has a unique uid, the charger details are recorded in the charging location.

Step 5: Post Pairing Confirmation

The user is notified in the app that the pairing has been successful.
The dashboard displays a status reflecting the absence of data until a session is initiated on the charger, keeping the user informed of the current status of the charger.

Step 6: Un-pairing

If a user decides to:

Unpair the charger via the SCSP or CPO interface
Deletes their CPO or SCSP account

The Smart Charging Service Provider communicates with the Charge Point Operator (CPO) to unpair the ChargingStation. As a result of this action:

The forwarding of charger data to the Smart Charging Service Provider is stopped.
Any charging profiles dispatched by the Smart Charging Service Provider for this ChargingStation are subsequently declined.
