OCPP2 Mock Server

This project includes an Open Charge Point Protocol (OCPP) version 2.0.1 mock server implemented in Python.

Prerequisites

This project requires Python 3.7+ and poetry to install the required packages:

poetry install --no-root

Running the Server

To start the server, run the server.py script:

poetry run task server

Or

poetry run python server.py

The server will start listening for connections on port 9000.

Running the server with OCPP command sending

You can also specify a command and a period duration with the --command and --period options respectively when running the server. The server will then send your chosen command to the connected client(s) every period seconds.

GetBaseReport Command

To run the server and send a GetBaseReport command every 5 seconds, use:

poetry run task server --command GetBaseReport --period 5

ClearCache Command

To run the server and send a ClearCache command every 5 seconds, use:

poetry run task server --command ClearCache --period 5

Please be mindful that these commands were examples according to the provided scenario, the available commands and their syntax might vary depending on the ocpp version and the implemented functionalities on your client.

Overview of the Server Scripts

Server.py

The server script waits for connections from clients. When a client connects, the server creates a new instance of the ChargePoint class. This class includes methods for handling various OCPP messages, most of which return a dummy response.

The server script uses the websockets and ocpp libraries to facilitate the implementation.

Development

Code formatting

poetry run task format

Code linting

poetry run task lint

Note

Primarily, this software is intended for testing applications. The server script don't adhere to the full OCPP specifications and it is advised not to use them in a production environment without additional development.
