Tecell’s Charge Management System (CMS) ensures seamless firmware updates for EV chargers regardless of the OCPP version in use. It leverages standardized update mechanisms defined by each protocol, allowing operators to manage firmware centrally while maintaining compatibility across different charger models and communication standards.
How firmware update protocols differ between OCPP 1.6J and OCPP 2.0.1
OCPP 1.6J uses a more limited update process, typically relying on the Central System to push firmware files via the existing communication channel. In contrast, OCPP 2.0.1 introduces enhanced capabilities for remote firmware management, including better handling of update statuses, rollback procedures, and more granular control over update scheduling. Tecell’s CMS supports both, adapting its behavior to the protocol’s specific commands and data structures.
For example, when a charger is running OCPP 1.6J, the CMS triggers a firmware download request through the existing connection, while OCPP 2.0.1 allows for more detailed progress tracking and conditional update logic. This flexibility ensures that operators can maintain consistent update practices across their fleet, even when using mixed protocol versions.
What this means for fleet operators and infrastructure providers
Fleet operators benefit from centralized control over firmware updates, reducing manual intervention and minimizing downtime. The CMS allows them to schedule updates during off-peak hours, ensuring that charging stations remain available for users. For infrastructure providers, this capability simplifies compliance with evolving standards and helps maintain a secure, up-to-date network of chargers.
Operators can also monitor update success rates and troubleshoot issues in real time. If a firmware update fails on a specific charger, the system flags it for attention, enabling quick resolution. This level of visibility is essential for maintaining service quality and avoiding costly on-site interventions.
