OCPP-PHP

A PHP library for implementing the JSON version of the Open Charge Point Protocol (OCPP). This library supports OCPP 1.6 (errata v4), OCPP 2.0.1 (Edition 2 FINAL, 2022-12-15, and Edition 3 errata 2024-11).

The purpose of this library is to provide the building blocks to construct a charging station/charge point and/or charging station management system (CSMS)/central system. It is not a complete solution but rather a flexible toolkit for developers to build OCPP-compliant systems.

Note: OCPP 2.0.1 includes fixes for all known issues in OCPP 2.0 and replaces it. Implementers are advised to use OCPP 2.0.1.

Features

• Full support for OCPP 1.6 and OCPP 2.0.1.
• PHP implementation of essential OCPP components.
• Modular and extensible architecture for building custom solutions.
• WebSocket integration for real-time communication between charging stations and central systems.
