UnityCharge’s CMS can perform real-time remote firmware updates on individual EV chargers in a fleet without cloud connectivity by leveraging Saha-Edge’s local edge computing capabilities. The system validates firmware updates using OCPP 2.0.1 protocols directly at the charger level, ensuring compliance and security even when offline. This approach enables fleet operators to maintain consistent software versions across their charging infrastructure while reducing dependency on constant internet access.
How Local Update Validation Works
The validation process occurs through Saha-Edge’s local processing units, which execute OCPP 2.0.1 validation routines directly on the charger. These routines check firmware integrity, version compatibility, and security certificates before initiating any update sequence. The charger maintains a secure local database of approved firmware versions and update policies, allowing it to make autonomous decisions about update eligibility.
This local validation ensures that only verified firmware reaches the charging station, preventing unauthorized or incompatible updates from compromising operations. The system also logs all validation events locally, providing operators with detailed audit trails even when network connectivity is unavailable.
Practical Implications for Fleet Operators
Fleet operators benefit from this capability during deployments in remote locations or areas with unreliable internet connectivity. For example, a utility company managing chargers across rural regions can schedule updates during network availability windows and allow chargers to apply updates autonomously when they reconnect.
This approach reduces operational overhead and ensures consistent software management across diverse deployment environments. Operators can also implement staged rollouts, where updates are first validated on a subset of chargers before broader deployment, minimizing risk to the entire fleet.
