## What it is
A Python package implementing the JSON version of the Open Charge Point Protocol (OCPP), supporting OCPP 1.6, 2.0.1, and Edition 3. It provides both client (charge point) and server (central system) implementations for EV charging communication.

## Use cases
- build an OCPP central system server for managing EV chargers
- implement an OCPP client for a charge point
- handle OCPP 1.6 and 2.0.1 messages in Python
- integrate EV charging stations with a backend
- simulate charge point communication for testing
- parse and validate OCPP JSON messages

## When to choose
- you need a Python implementation of OCPP 1.6 or 2.0.1
- you are building EV charging infrastructure software
- you want both charge point and central system support in one library

## When to avoid
- you need SOAP-based OCPP (only JSON/WebSocket versions are supported)
- you need a complete turnkey charging station management system rather than a protocol library

## Facets
- artifact type: framework
- maturity: active
- function: websocket, api-framework, serialization
- domain: iot, apis, developer-tools
- platform: python, cross-platform
- tags: ocpp, electric-vehicles, ev-charging, charge-point, central-system, protocol-implementation
