    OCPP 1.6 vs 2.0.1: What CPOs Need to Know About Support Automation

    January 28, 2026EVCalls Team

    Understanding OCPP Versions

    The Open Charge Point Protocol (OCPP) is the standard communication protocol between charging stations and central management systems. As networks grow, understanding how different OCPP versions affect support automation becomes essential.

    OCPP 1.6: The Current Standard

    OCPP 1.6 remains the most widely deployed version. It supports core operations like remote start/stop, status notifications, and firmware management. However, its SOAP-based architecture can limit real-time diagnostic capabilities.

    OCPP 2.0.1: The Next Generation

    OCPP 2.0.1 introduces significant improvements including device management, improved security with certificate-based authentication, and richer telemetry data. For AI support systems, this means more data points for automated diagnostics.

    What This Means for AI Support

    • OCPP 2.0.1 provides richer error codes for more accurate AI diagnostics
    • Device management features enable remote resolution of more issue types
    • Certificate-based security improves the reliability of AI-to-charger communication
    • Both versions are fully supported by EVCalls AI agents

    EVCalls: Protocol-Aware AI

    EVCalls AI agents are designed to work seamlessly with both OCPP 1.6 and 2.0.1. Our protocol-aware diagnostics automatically adapt to the version running on each charger, ensuring accurate troubleshooting regardless of your hardware mix.
