OCPP Stack

Delta OCPP (Open Charge Point Protocol) Stack provides a standardized communication solution between charging stations and charging management systems. It enables interoperability across multi-vendor charging infrastructure and backend platforms, helping charging operators, EVSE manufacturers, and energy service providers build scalable and connected EV charging networks.

Our OCPP Stack supports mainstream OCPP versions, including OCPP 1.6 and OCPP 2.0.1, with a roadmap toward OCPP 2.1. With a modular and portable architecture, it helps customers integrate charging station communication, backend connectivity, device management, transaction handling, security, smart charging, display and messaging functions, and other OCPP-based features into their charging platforms.

OPEN CHARGE POINT PROTOCOL 2.0.1

OCPP 2.0.1 builds on OCPP 1.6 with enhanced capabilities for modern charging infrastructure, including improved device management, transaction handling, security, smart charging, display and messaging support, and additional improvements requested by the EV charging community.
