Tecell’s Charge Management System (CMS) enables simultaneous firmware updates for multiple chargers using OCPP 2.0.1, with built-in rollback capabilities that allow operators to revert to previous versions if issues arise during or after an update.
How it works in practice
In real-world deployments, CMS groups chargers by firmware version and update status, allowing operators to schedule updates in batches. This approach minimizes downtime and ensures consistent performance across fleets. The system supports both automatic and manual update triggers, giving flexibility based on operational needs.
When an update fails or introduces compatibility issues, rollback functionality activates immediately. This feature preserves the previous firmware version and reverts the charger to its prior state without requiring physical intervention. Operators can review logs and diagnostics before deciding whether to retry or investigate further.
What this means for fleet operators
Fleet managers benefit from centralized control over firmware updates, reducing the complexity of managing large-scale deployments. With rollback capabilities, they can confidently deploy new firmware knowing that any problems can be quickly reversed. This reduces risk and increases operational confidence when upgrading charging infrastructure.
For example, a fleet operator deploying 500 chargers across multiple sites can initiate a firmware update for all units simultaneously. If one site experiences unexpected behavior, the system automatically rolls back only that subset, leaving the rest unaffected. This granular control ensures minimal disruption to service.
