Tecell’s platform maintains secure communication with chargers using both OCPP 1.6J and OCPP 2.0.1 through standardized TLS encryption, mutual authentication, and protocol-specific message validation. The system dynamically adapts to each version’s security requirements while preserving consistent access control and data integrity.
Security Implementation Details
The platform enforces TLS 1.3 for all communications, ensuring that data exchanged between chargers and the backend remains encrypted and tamper-proof. Each charger must present a valid certificate during the handshake process, which Tecell verifies against a trusted certificate authority. This mutual authentication prevents unauthorized devices from connecting to the network.
For OCPP 1.6J, Tecell applies legacy security measures such as secure HTTP headers and message signing. In contrast, OCPP 2.0.1 supports enhanced features like automatic certificate renewal and more robust key exchange mechanisms. Tecell’s software layer abstracts these differences, allowing operators to manage both versions seamlessly without compromising security.
Practical Benefits for Operators
Operators benefit from a unified dashboard that displays real-time status updates from chargers regardless of their OCPP version. This consistency simplifies troubleshooting and reduces operational overhead. The platform also logs all communication attempts, providing audit trails that help meet compliance standards.
When deploying new chargers or upgrading existing ones, Tecell ensures backward compatibility without requiring manual configuration changes. This capability is especially valuable in large-scale installations where mixing older and newer hardware is common. Operators can confidently expand their networks knowing that security protocols remain intact across all devices.
