OCPP 2.0.1 can support real-time cross-protocol session synchronization between CCS1 and Type 2 connectors within the same charging station, provided the implementation adheres to ISO 15118 Plug & Charge standards and maintains session continuity. The protocol’s enhanced messaging capabilities and flexible data models allow for handling multiple connector types and their unique communication requirements.
How It Works in Practice
In practice, this synchronization requires the charging station to manage two distinct communication channels—one for each connector type—while ensuring that session data, such as authorization and energy delivery metrics, are consistently updated across both. The CMS must interpret and relay messages between the two protocols without introducing delays or inconsistencies that could disrupt charging operations.
OCPP 2.0.1’s support for dynamic messaging and event-based communication enables the system to react to changes in connector status or user interaction in real time. This is especially important when a user switches between CCS1 and Type 2 connectors during a single charging session, as the system must maintain a seamless experience.
For operators, this capability ensures that all charging sessions are accurately tracked and billed, regardless of which connector is used. It also supports advanced features like load balancing and smart charging, where the system needs to monitor and control multiple charging points simultaneously.
Implications for Charge Point Operators
For Charge Point Operators (CPOs), implementing OCPP 2.0.1 with cross-protocol session synchronization means greater flexibility in deploying charging stations that support multiple vehicle types. This is particularly valuable in urban environments where mixed-use charging stations are common.
It also simplifies compliance with evolving standards, such as those related to Plug & Charge, which require that authentication and authorization processes are seamless and secure. CPOs can rely on OCPP 2.0.1 to maintain session integrity even when vehicles use different charging standards.
Operators benefit from reduced operational complexity, as the system handles the intricacies of protocol translation and session management automatically. This allows them to focus on scaling their networks and improving user experience rather than troubleshooting cross-protocol issues.
