Saha-Edge Offline Diagnostics with OCPP 2.0.1

Saha-Edge enables real-time offline diagnostics and fault logging for individual AC chargers using OCPP 2.0.1 without cloud connectivity, maintaining compliance with ISO 15118 Plug & Charge through local data processing and secure communication protocols.

How Saha-Edge Handles Offline Operations

When cloud connectivity is unavailable, Saha-Edge maintains full diagnostic capabilities by storing event logs locally on the edge device. The system continues to monitor charger status, record faults, and log communication events using OCPP 2.0.1 standards. These logs are retained until connectivity is restored, at which point they are synchronized with the central CMS for comprehensive analysis.

This local processing ensures that critical information about charger performance and faults is never lost. The edge platform also supports secure communication protocols that maintain compliance with Plug & Charge requirements even in disconnected scenarios. Data integrity is preserved through cryptographic signing of logs and secure storage mechanisms.

Practical Implications for Charge Point Operators

For CPOs managing networks in remote or low-connectivity areas, this capability ensures continuous monitoring without relying on constant internet access. Operators can identify and resolve issues proactively, reducing downtime and improving user satisfaction. The system’s ability to maintain Plug & Charge compliance means that security standards are upheld regardless of network conditions.

Field technicians benefit from detailed offline logs that provide context for troubleshooting. These logs contain timestamps, error codes, and operational data that help diagnose problems quickly. The seamless transition between offline and online modes ensures that no diagnostic information is lost during network interruptions.
