OCPP 2.0.1: Part 2 - Specification

This specification is intended for developers, manufacturers, and operators involved in the electric vehicle (EV) charging infrastructure ecosystem. It is particularly relevant for those designing, implementing, and maintaining charging stations and charging station management systems (CSMS). The document assumes a strong understanding of networking protocols, security concepts, and EV charging technologies. It caters to engineers, software architects, product managers, and technical consultants working in the EV industry, as well as certification bodies and regulatory agencies involved in ensuring interoperability and compliance of EV charging infrastructure.

The Open Charge Alliance (OCA) is a global consortium of public and private entities that collaborate to develop and promote open standards for EV charging infrastructure. OCA facilitates interoperability, reduces complexity, and fosters innovation in the EV charging market. The organization comprises experts from various sectors, including EV manufacturers, charging station vendors, energy providers, and research institutions. OCA's work is driven by the collective knowledge and experience of its members, who contribute to the development and maintenance of OCPP and other open standards. The alliance aims to create a level playing field for all stakeholders in the EV charging ecosystem, enabling seamless and reliable charging experiences for EV drivers worldwide.

The Open Charge Point Protocol (OCPP) was created to standardize communication between EV charging stations and management systems. Before OCPP, the lack of a unified protocol led to interoperability issues, hindering the growth of the EV charging infrastructure. OCPP 1.0 was the first attempt to address this problem, followed by OCPP 1.5 and 1.6, which gained widespread adoption. OCPP 2.0 and 2.0.1 represent significant advancements, incorporating new functionalities, enhanced security features, and improved support for smart charging applications. These versions reflect the evolving needs of the EV market, driven by the increasing adoption of EVs, the demand for faster charging, and the integration of charging infrastructure with smart grids and energy management systems. The development of OCPP 2.0.1 also takes into account the growing importance of ISO 15118 for advanced charging functionalities.
