KEBA KeContact P30 OCPP configuration

This article describes the necessary configuration settings to connect a KEBA KeContact P30 with the be.ENERGISED backend. You can configure the charging station either via the administration front end of the charging station or via the configuration file.

Configuration via web frontend

The KEBA KeContact P30 offers a web frontend for configuring the parameters. To call up the configuration of the charging station, navigate with your web browser to the IP address of the charging station in the local network. Further information on this can be found in the user manual of the charging station.

Under the menu item Configuration you will find the setting OCPP. On the following page, you can now configure the configurations as follows. 

Operating Mode

• Operating Mode: Single Chargepoint or Charging Network 
• Number of Slaves: Enter the number of your C-Series stations
• Master Serial No: Is given
• Slave - Serial No: Enter the respective serial number according to the type plate
• Availability: Each chargepoint should be activated as "available" individually.

Network

For the follwoing example, we use the configuration data from this article to connect the charging station with SIM cards from ChargePoint (starting with 8988).

• Local DHCP Server: ON for master-slave combinations / OFF for a single station
• WLAN/Wifi Connection: ON
• WLAN/WiFi SSID: Name of the WLAN network display
• WLAN/WiFi Password: Enter a secure password
• Mobile Communications: ON
• APN: wm
• APN Username: wm
• APN Password: wm
• SIM PIN: blank 

OCPP
Then configure the OCPP parameters as follows:

• Chargepoint Identity: specify a unique name 

• OCPP Communication Type: OCPP_16_JSON

• Central System Hostname: INSTANCE.private.ocpp-broker.com
  
  • Please replace the value "INSTANCE" with your instance name
  • You can easily find out your instance (account) name in the link to the backend. Access to the backend: https://example.htb.solutions/. Here you can read out the instance by taking the value AFTER "https://" and BEFORE ".htb.solutions/". In this example the INSTANCE is called "example".
• Central System Port: 80
• Central System Path: ocpp/cp/socket/16 (*if the charging station does not establish a connection, in some cases the chargepoint identity must be entered again after "/16": ocpp/cp/socket/16/Chargepoint Identity)
• Secure Central System Connection: OFF
• Predefined Token: FFFFFF

To confirm the set parameters, click the "Apply" button at the lower part of the page.

The station then performs a restart on its own.  

The charging stations should now be connected to the backend. Under the "Status" tab, you can check whether the URL was transferred correctly and if the "State" has the value "Reachable" or "ONLINE" and a heartbeat was received.
