OCPP Security Across Mixed Versions

Tecell’s platform maintains secure communication with chargers using both OCPP 1.6J and OCPP 2.0.1 by implementing dynamic TLS negotiation and version-aware message routing. The system automatically detects the protocol version of each charger and applies the appropriate security policies, ensuring encrypted connections and authenticated exchanges regardless of the OCPP version in use.

How It Works in Practice

In a mixed-version fleet, Tecell’s ChargeSphere software acts as a central coordinator that negotiates secure connections with each charger individually. It uses certificate-based authentication and TLS 1.3 for all communications, adapting to the capabilities of each charger’s OCPP implementation. This means that even if some chargers only support OCPP 1.6J, the system still enforces secure communication through compatible encryption methods.

The platform also maintains a secure session registry that tracks which chargers are using which version. This allows for granular control over access policies and ensures that any security updates or patches are applied consistently across the entire fleet, regardless of protocol differences.

What This Means for Fleet Operators

Fleet operators benefit from a unified dashboard that shows the security status of all chargers, regardless of their OCPP version. This visibility helps ensure compliance with security standards and simplifies audits. Operators can also configure different security profiles for different charger types, allowing for more granular control over access and data flow.

For example, a fleet operator managing chargers from multiple vendors might have some units supporting OCPP 2.0.1 and others on 1.6J. Tecell’s platform ensures that all units are equally protected, with no single point of failure due to protocol mismatch.
