USE-Case

For public charging stations, the AFIR requires a safe payment solution.
In the Case case of AC charging stations and wallboxes wall boxes, this safe payment solution can be a QR Code in the display that links to a payment site.
The payment site, operated by the backend operator, can than then handle the payment and send a RemoteStartTransaction to the charging point.
The AFIR additionally requires the QR -Codes codes to be charge point specific.

Implementation

The charging stations with FW 6.12.X and the following have the possibility for the operator to display a QR Code on the display.

The configuration keys listed below can be used to display a payment QR Code on the station. These can be filled with a URL that is then displayed on the charger as a QR code. All keys can be edited via Ducto and OCPP.

The charging stations with more than one charge point have separate keys for the right and left charge -pointpoints, and the QR code is displayed in the usual rotation of the different screensonce a vehicle is connected to a charge point.

If no value is entered into the keys, then no QR -Code code will be displayed.

If the charge-point is in ‘ChargeForFree’ Mode no QR Code code will be displayed.

In case of a communication error where the backend can not be reached a QR-Code will not be displayed to avoid problems with authentication. There will be an indication to the user that Ad-hoc payment is temporarily unavailable.
