OCPP - The Heart of Electric Vehicle Charging Infrastructure
As electric vehicles (EVs) rapidly enter our lives, the charging infrastructure for these vehicles is developing at the same pace. However, for charging stations developed by hundreds of different manufacturers to work compatibly with each other, a common "language" is needed. This is where OCPP (Open Charge Point Protocol) comes into play.

What is OCPP?
OCPP is an open and manufacturer-independent communication protocol that enables communication between charging stations and central software (charge point management systems - CPMS). It was first developed in 2009 by the Netherlands-based Open Charge Alliance (OCA) and is now one of the most widely used standards in charging infrastructure worldwide.

Why is OCPP Used?
The purpose of OCPP is to ensure that charging devices and management systems from different manufacturers work seamlessly with each other. This allows charging station owners to freely choose their management software without being tied to a specific manufacturer.

Key advantages:
? Device Independence: Provides brand independence on both hardware and software sides.
? Security: With OCPP 2.0.1, it offers security measures such as TLS and certified authentication.
⚙️ Remote Management: Functions such as remote monitoring, control, and updating of charging points are supported.
? Advanced Reporting: Data such as energy consumption, session history, and error codes can be easily tracked.

OCPP Versions
OCPP 1.6: This is the most widely used version. It offers JSON-based communication and basic remote management capabilities.

OCPP 2.0 / 2.0.1: Offers a more advanced structure. It supports smart charging, user authentication, security protocols, and more.

Note: For new installations, transitioning to OCPP 2.0.1 is now recommended, but 1.6 is still widely used due to field compatibility.

What Can Be Done with OCPP?
Charging start/stop commands can be sent
Authorization can be made according to different user types
Software updates can be installed remotely
Real-time error notifications can be received
Dynamic energy management scenarios can be implemented
