How OCPP works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
The Open Charge Point Protocol defines messages exchanged between charging stations and central systems for authorization, transactions, monitoring, smart charging, diagnostics, and device management. It supports interoperable charging operations and can contribute to fleet and managed-charging platforms, but it does not define the vehicle-side V2X radio or power-transfer interface.

Standards
OCPP 1.6
OCPP 1.6 defines management messages exchanged between charging stations and central systems. It matters to V2X because it gives independently developed systems a common technical contract.
OCPP 2.0.1
OCPP 2.0.1 defines charging-station management with device modeling, security, smart charging, and ISO 15118 support. It matters to V2X because it gives independently developed systems a common technical contract.
OCPP 2.1
OCPP 2.1 defines newer charging-station management functions including bidirectional charging and distributed-energy integration. It matters to V2X because it gives independently developed systems a common technical contract.
