OCPP Simulator

Overview

This project is a simple Electric Vehicle (EV) Charger Simulator that follows the Open Charge Point Protocol (OCPP) standards. It provides a graphical user interface (GUI) built using tkinter to simulate the behavior of an EV charging station. The simulator supports basic OCPP 1.6 functionalities, including boot notification, authorization, start and stop transactions, status notifications, and sending meter values.

Features

• Boot Notification: The simulator can send a boot notification to a central system, establishing a connection and receiving an interval for sending heartbeats.

• Authorization: It supports authorizing RFID tags, allowing or denying access to the charging station.

• Start Transaction: The simulator can initiate a charging transaction with specified parameters such as connector ID, RFID tag, and meter start value.

• Stop Transaction: It simulates stopping a transaction with details like meter stop value and reason.

• Heartbeat: The simulator sends periodic heartbeats to the central system.

• Meter Values: It can send meter values, including energy consumption, during a charging session.

• Status Notification: The simulator can send status notifications to update the central system about the charging station's status.

Getting Started

Prerequisites

• Python 3.7 or higher
• websockets library
• ocpp library

Installation

1. Clone the repository:

   git clone https://github.com/your-username/ocpp-simulator.git
   cd ocpp-simulator

2. Install dependencies:

   pip install -r requirements.txt

Usage

1. Run the simulator:

   python ocpp_simulator.py

2. Fill in the required information in the GUI, such as the central station WebSocket URL, charge station serial number, RFID tag, etc.

3. Use the provided buttons to perform actions like connecting to the central system, authorizing RFID tags, starting and stopping transactions, and more.

4. View the console output for detailed logs and simulation information.
