Tecell’s Charge Management System (CMS) calculates and reports charging session data by capturing real-time energy consumption, vehicle state, and communication logs from AC/DC chargers. It uses standardized protocols like OCPP 1.6 and 2.0.1 to ensure accurate billing reconciliation across hybrid networks. The system aggregates data per session, validates it against charging station logs, and generates detailed reports for operators and fleet managers.
How Session Data is Collected and Validated
The CMS pulls session data directly from the charging point via OCPP, capturing start and stop times, kWh delivered, and power levels. It cross-references this with the vehicle’s battery state and the charger’s internal logs. This dual validation ensures that billing data matches actual charging behavior, even in complex hybrid setups with multiple charger types.
For example, when a vehicle switches from AC to DC charging mid-session, the system tracks both transitions and maintains a continuous billing record. This prevents discrepancies that often occur in multi-phase charging environments.
What This Means for Fleet and Facility Managers
Fleet managers benefit from detailed session reports that show energy usage per vehicle, enabling cost allocation and operational efficiency tracking. Facility managers can monitor real-time energy consumption and identify underperforming chargers or peak usage times.
By providing granular data, Tecell’s CMS supports accurate billing reconciliation, reduces disputes, and helps operators optimize their charging infrastructure investments. The system also enables automated reporting, saving time and reducing manual errors.
