Integratig Teltonika EVC stations with OCPP 1.6 JSON

This guide explains how to integrate Teltonika EVC stations with your existing system using the OCPP 1.6 JSON protocol.

Getting started

Before you begin, you will need the following:

• Teltonika EVC station is installed and configured.
• Teltonika EVC station has access to the internet.
• Knowledge of the OCPP 1.6 JSON protocol.

Steps

1. Configure the charging station to connect to your OCPP 1.6 JSON server. You will need to know the IP address or domain name of your server and the port number for the OCPP 1.6 JSON protocol.

2. Set up a charging station account on your OCPP 1.6 JSON server. You will need to provide the following information:

   * Charging station ID: This is a unique identifier for your charging station.
   * Charging station type: Specify the type of charging station you have. (AC)
   * Other settings as required by your OCPP 1.6 JSON server.

3. Connect the charging station to your OCPP 1.6 JSON server. The charging station will communicate with your server using the OCPP 1.6 JSON protocol.

4. Test the connection by starting a charging session from your OCPP 1.6 JSON server.

5. Monitor the charging station from your OCPP 1.6 JSON server. You will be able to view the charging status, energy usage, and other important information about the charging station (for configuration keys available at the moment from Teltonika EVC station please communicate with your Sales manager or directly through Teltonika Energy VIP HelpDesk).

How to connect Teltonika EVC stations to chosen OCPP provider

• Connect Teltonika EVC station to the internet - make sure, that the charging station has the internet connection. (all types are acceptable)

• Connect Teltonika EVC station to the chosen OCPP server

OCPP provider must give you info about:

1. URL address - URL address must end with "/"
2. Charge point ID - Most of the time it's the serial number of the charging station

When you have that information, insert it as shown in the picture below and press save.
