Tecell’s Charge Management System (CMS) allows operators to perform real-time diagnostics on EV chargers without physical access by leveraging standardized communication protocols like OCPP 1.6 and 2.0.1. The system collects and analyzes data from chargers remotely, enabling troubleshooting, performance monitoring, and proactive maintenance from a centralized dashboard.
How remote diagnostics work in practice
In practice, the CMS connects to chargers via secure network protocols, pulling live telemetry data such as power consumption, error codes, and operational status. Operators can view this information instantly through the web-based interface, identifying issues like communication failures, hardware malfunctions, or charging session anomalies. This eliminates the need for on-site visits for routine checks or initial diagnostics.
For example, if a charger reports an unexpected drop in power output, the CMS can flag this as a potential issue. The operator can then review logs, check for firmware updates, or dispatch a technician only when necessary. This approach significantly reduces downtime and improves response times.
What this means for fleet and commercial operators
For fleet managers and commercial charging operators, remote diagnostics mean better control over large deployments. Instead of manually checking each station, they can monitor hundreds of chargers from one location. This is especially valuable for installations in remote or hard-to-reach areas.
It also supports predictive maintenance strategies. By analyzing usage patterns and historical data, the CMS can alert operators before a failure occurs. This proactive stance helps avoid service interruptions and extends the lifespan of charging infrastructure.
