Yes, OCPP 2.0.1 can enable real-time ISO 15118-2 Plug & Charge session initiation without cloud connectivity when used with Saha-Edge’s edge-AI capabilities. The edge platform handles local authentication and session management, allowing seamless plug-and-play charging even in offline scenarios.
How It Works in Practice
Saha-Edge acts as a local controller that processes ISO 15118-2 communication directly at the charging point. It uses embedded AI to authenticate EVs based on pre-registered credentials, eliminating the need for constant cloud connectivity. This setup ensures that charging sessions can begin immediately upon plug-in, without relying on external servers.
The system stores EV identification and authorization data locally, enabling secure and fast session start-up. Even if network connectivity is lost, the charging station continues to operate using cached credentials and local decision-making.
This approach is particularly useful in remote or low-connectivity areas where maintaining a stable internet connection is challenging. It also improves response times and reduces latency in session initiation.
What This Means for Charge Point Operators
For Charge Point Operators (CPOs), this capability enhances operational reliability and user experience. Charging stations can maintain service continuity during network outages, ensuring customers aren’t blocked from charging their vehicles.
It also simplifies compliance with ISO 15118-2 standards, which require secure and standardized communication between EVs and charging infrastructure. CPOs benefit from reduced dependency on cloud services, lowering both operational complexity and potential points of failure.
Operators can deploy scalable, resilient charging networks that meet evolving regulatory requirements while minimizing downtime and improving customer satisfaction.
