Tecell’s Charge Management System (CMS) ensures secure communication with charging hardware through end-to-end encryption, mutual authentication, and real-time monitoring of communication channels. All data exchanged between chargers and the CMS is encrypted using industry-standard protocols, and each device must authenticate itself before establishing a connection. The system also implements automatic security updates and intrusion detection to maintain a secure environment.
How encryption and authentication work in practice
The CMS uses TLS 1.3 encryption for all communication between chargers and the central system. Each charging station is provisioned with a unique digital certificate during deployment, ensuring that only authorized hardware can connect. This mutual authentication process prevents unauthorized devices from accessing the network or manipulating data.
Additionally, the CMS enforces strict access controls. Only users with valid credentials and appropriate permissions can initiate or modify charging sessions. This layered approach ensures that even if one component is compromised, the overall system remains protected.
What this means for fleet operators and facility managers
Fleet operators benefit from secure communication because it guarantees that charging data—such as session logs, energy consumption, and billing details—remains intact and tamper-proof. Facility managers can trust that their charging infrastructure operates reliably without risk of external interference or data breaches.
For example, a large commercial property using Tecell’s CMS can confidently monitor hundreds of chargers across multiple buildings, knowing that each communication channel is protected. This security framework also supports compliance with data protection regulations, which is essential for businesses handling sensitive user information.
