Tecell’s Charge Point Management System (CMS) enables simultaneous firmware updates across 1000+ chargers through a distributed, prioritized update queue. The system automatically groups chargers by model, firmware version, and location to optimize bandwidth and reduce downtime. Updates are scheduled during off-peak hours and can be paused or rolled back if issues arise. This approach ensures consistent, reliable upgrades without disrupting charging operations.
How updates are prioritized and scheduled
The CMS evaluates each charger’s current firmware version, model compatibility, and operational status before assigning update priority. Critical security patches are deployed first, followed by feature enhancements. Updates are batched to avoid overwhelming network capacity and are scheduled during low-usage periods. The system also allows manual override for urgent deployments, ensuring flexibility for fleet operators and infrastructure providers.
What happens during a large-scale update
During a large-scale update, Tecell’s CMS monitors each charger’s progress in real time. If a charger fails to respond or encounters an error, the system flags it for manual review. The update process includes rollback capabilities, so if a new firmware version causes issues, the system can quickly revert to the previous stable version. This ensures minimal disruption to users and maintains service availability across the entire fleet.
