UnityCharge’s Charging Management System enables real-time remote restart of individual EV chargers in a fleet even without cloud connectivity by leveraging local OCPP 2.0.1 session management and edge computing capabilities. The system maintains session state locally and can execute restart commands through direct communication with chargers via OCPP 2.0.1, ensuring operational continuity during network outages.
How Local Session Management Works
UnityCharge uses OCPP 2.0.1’s built-in session management features to maintain real-time control over charging sessions even when cloud connectivity is lost. The system stores session data locally on edge devices, allowing operators to monitor and manage chargers directly from their local network. This approach ensures that critical functions like restarting a stuck charger or updating firmware can proceed without requiring an active internet connection.
When a charger is offline, UnityCharge’s edge computing layer continues to track its status and can queue commands for execution once connectivity is restored. This local-first architecture reduces dependency on centralized infrastructure and improves resilience for fleet operations in remote or low-connectivity environments.
Practical Implications for Fleet Operators
Fleet operators benefit from this capability during routine maintenance or unexpected downtime scenarios. For example, if a charger becomes unresponsive due to a temporary network issue, an operator can remotely restart it using UnityCharge’s CMS interface, which then communicates directly with the device via OCPP 2.0.1. This eliminates the need for on-site intervention and reduces operational delays.
Additionally, this feature supports proactive fleet management by enabling operators to schedule restarts during off-peak hours or respond quickly to customer requests. The system’s ability to function independently of cloud connectivity also enhances security by minimizing exposure to external threats and reducing reliance on third-party infrastructure.
