When a charger switches from OCPP 1.6J to OCPP 2.0.1 during an active charging session, Tecell’s CMS ensures session integrity by maintaining the session state and communication context. The system automatically detects the protocol change and adapts its message handling to align with the new version while preserving all session data and charging metrics. It manages the transition without interrupting the ongoing charge, ensuring compliance with both OCPP standards and operational continuity.
How the transition works in practice
Tecell’s CMS monitors protocol versions in real time and initiates a graceful handover when a charger switches from OCPP 1.6J to 2.0.1. The system preserves session identifiers, transaction data, and charging status to maintain continuity. It also validates that all required fields and parameters are compatible between the two versions. This process prevents data loss or session termination during the protocol shift.
What this means for charge point operators
For charge point operators, this seamless handling means minimal disruption to users and consistent billing accuracy. The CMS ensures that even if a charger updates its OCPP version mid-session, the operator’s systems continue to track charging correctly. It also supports compliance with roaming agreements that may require specific protocol adherence. Operators can rely on Tecell’s CMS to maintain reliable operations across mixed-version deployments.
