OCPIPyBridge 0.1.1

Python library for Open Charge Point Interface (OCPI) protocol

OCPIPyBridge: A Python Library for OCPI Protocol

Overview

OCPIPyBridge is a Python library tailored for implementing the Open Charge Point Interface (OCPI) protocol. It offers structured models and validation for various OCPI entities, ideal for developers creating applications for EV charging infrastructure and services.

Features

• Models for key OCPI entities: Location, EVSE, Connector, CDR, Command, Transaction, Feedback, Meter, Reservation, Tariff, User, and Credentials.
• Validations align with OCPI standards using Pydantic.
• Supports diverse OCPI operations and functionalities.

Installation

Install OCPIPyBridge using pip:

pip install OCPIPyBridge

Usage

Import the required models from OCPIPyBridge:

from ocpi_py_bridge.models import Location, EVSE, Connector, CDR, Command, Transaction, Feedback, Meter, Reservation, Tariff, User, Credentials

Model Usage Examples

Example of how to instantiate and use each model:

Location

from ocpi_py_bridge.models import Location

location_data = {
    "id": "loc1",
    "type": "ON_STREET",
    "name": "Main Street Charging Station",
    # ... other location details ...
}

location = Location(**location_data)
print(location.json())

... (Similar examples for other models)

Integration with Flask/FastAPI

Flask Example

from flask import Flask, request, jsonify
from ocpi_py_bridge.models import CDR

app = Flask(__name__)

@app.route('/api/cdr', methods=['POST'])
def handle_cdr():
    try:
        cdr_data = request.json
        cdr = CDR(**cdr_data)
        # Process and save CDR data
        return jsonify({"message": "CDR data processed successfully."}), 200
    except ValueError as e:
        return jsonify({"error": str(e)}), 400

if __name__ == '__main__':
    app.run(debug=True)

FastAPI Example

from fastapi import FastAPI, HTTPException
from pydantic import ValidationError
from ocpi_py_bridge.models import CDR

app = FastAPI()

@app.post('/api/cdr')
async def handle_cdr(cdr_data: CDR):
    try:
        cdr_data.validate()
        # Process and save CDR data
        return {"message": "CDR data processed successfully."}
    except ValidationError as e:
        raise HTTPException(status_code=400, detail=str(e))
