Introduction

In this document, Compleo explains the QR Code function for Ad-Hoc payment, how it is implemented and how it can be used by the operator.

Hardware

All AC-Hardware with a P5 Controller can use this feature once updated to 6.12.0 or higher.

USE-Case

For public charging stations, the AFIR requires a safe payment solution.
In the case of AC charging stations and 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 then handle the payment and send a RemoteStartTransaction to the charging point.
The AFIR additionally requires the QR 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 points, and the QR code is displayed once a vehicle is connected to a charge point.

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

If the charge-point is in ‘ChargeForFree’ Mode no QR 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.
