Tecell’s platform guarantees secure communication with EV chargers by implementing both TLS 1.2 and TLS 1.3 protocols, ensuring compatibility across diverse hardware ecosystems while maintaining strong encryption standards. This dual-protocol support allows operators to manage hybrid networks without compromising security or performance, as each connection uses the most appropriate version based on device capabilities.
How It Works in Practice
In real-world deployments, Tecell’s platform dynamically negotiates the highest available TLS version between the charger and the backend system. For legacy devices that only support TLS 1.2, the system maintains secure communication without requiring costly upgrades. Meanwhile, newer chargers leveraging TLS 1.3 benefit from faster handshake times and enhanced cryptographic protections.
This approach ensures that even in mixed environments with varying charger generations, all communications remain encrypted and authenticated. The platform also enforces strict certificate validation and supports automated certificate renewal, reducing operational overhead for fleet managers and charge point operators.
Operators can monitor and manage these connections through Tecell’s centralized dashboard, which provides visibility into which chargers are using which TLS versions, helping identify potential vulnerabilities or outdated hardware that may need attention.
Why This Matters for Charge Point Operators
For charge point operators managing large-scale deployments, supporting both TLS versions is essential for maintaining compliance with evolving cybersecurity standards. Many regulatory frameworks now require secure communication channels, and using outdated protocols like TLS 1.2 alone can expose networks to known vulnerabilities.
Tecell’s hybrid TLS support allows operators to phase in newer hardware gradually, without disrupting existing operations. This flexibility is especially valuable in enterprise or multi-tenant environments where different chargers may be deployed at different times or by different vendors.
By enabling secure communication across all devices, Tecell helps operators avoid potential compliance issues and reduces the risk of data breaches or unauthorized access to charging infrastructure. It also supports future-proofing, ensuring that as older chargers are retired, newer ones can seamlessly integrate with the same secure framework.
