This article describes the necessary configuration settings to connect an ABL charging station to the be.ENERGISED backend.
The charging station is configured via the configuration interface by accessing the charging station locally.
First, we will describe the "private" connection between the charging station and the be.ENERGISED backend. In the first step, access the charging station interface. Refer to the charging station's user manual in case of any questions regarding this. Once you have access, you will see this view.
To make the OCPP configuration settings, it is sufficient to be logged in as "OWNER". Otherwise, you can also take on another role via the "Change role" button.
In the next step, go to the "Connectivity" tab and then to "Mobile".
Here you enter the APN data of the SIM card used. Here in the example we use the configuration data from the following article for the connection of the charging station with SIM cards from has·to·be (starting with 8988).
|Please note that this article only refers to SIM cards from has·to·be. Alternatively, you must use different APN information from your SIM card provider. Please note that the OCPP endpoints may also have to be adapted to your provider.|
Once the APN data has been entered, go to "save".
After that, go to the "OCPP" tab.
OCPP version: 1.6
Address (URL) of the backend: Please replace the value "INSTANCE" with your instance name. You can easily read your instance name in the link to the backend. Access to the backend: https://beispiel.htb.solutions/. Here you can read out the instance by taking the value AFTER "https://" and BEFORE ".htb.solutions/". In this example, your instance name would be "beispiel". An overview of the URLs, depending on the connection type, can be found in this article.
ChargeBox ID for the station: replace the ChargeBox ID with a unique station name. This means that among all your stations, this name (or ID) may be assigned only once.
Please note that the chargepoint identity must not contain spaces, special characters (e.g.: +*!#) and letters unknown in English (e.g.: ä, ö, ü, ß). Exception is the underscore (_), this can be used.
Furthermore, the chargepoint identity must not exceed a maximum length of 45 characters.
Local Port: This can be left at "7890" by default.
Local path: This can be left at "/Chargepoint" by default.
Password for basic authentication: This is not required for a "private" connection, but is required for a "public" connection. More about this below.
After you have entered these values, go to "Save" here as well. You will get a message that you have to restart the charging station to apply the changes.
To restart the charging station, go to the "Maintenance" tab under "System" and select "Perform hard reset".
The charging station is restarted and should then be displayed as online in the backend.
The "public" connection differs in some points from the "private" connection described above.
For the "public" connection variant, it is even more important that you ensure that your ABL charging station has the latest firmware version!
Note: For a "public" connection (see also OCPP endpoints), a TLS certificate must be uploaded for ABL stations. This can be downloaded from the DigiCert website, for example. Two certificates are required:
1. DigiCert TLS RSA SHA256 2020 CA1
2. DigiCert High Assurance EV Root CA
Port "443" must be used for all public and secure variants.
For the "public" connection, select the "public" URL and specify the port (443) after "ocpp-broker.com".
As with the "private" connection, replace the "INSTANCE" value with your instance name. For the "public" connection, the charging station must support BASICAUTH. Where you can see your password for BasicAuth in be.ENERGISED can be read in the article on OCPP endpoints. The password must be entered here.
Do not be confused by the decimal points displayed in the Basic Authentication Password field. These do not correspond to the actual length of the password you entered, but are displayed that way by default.
Go to "Save" and in the next step to the item "TLS", where you upload the above-mentioned TLS certificates. In the "Supported TLS versions" item, please select the latest version, which is currently TLSv1.3.
After that, restart the charging station again and a "public" connection with the be.ENERGISED backend should be established successfully.
