SAFT RAILWAY MAINTENANCE C.O.M.M. Batt monitoring system C.O.M.M. Batt provides real-time remote monitoring for onboard nickel-technology rail batteries to enable predictive maintenance for longer life and lower operational costs. Through continuous, real-time measurement of operational data, C.O.M.M. Batt indicates the capability of the battery to fulfill its mission profile and provides remote monitoring for onboard nickel-technology batteries. By applying Saft’s proprietary modeling algorithms to this data, C.O.M.M. Batt offers an accurate picture of battery system health to enhance battery management, diagnostics, maintenance and service. By putting the emphasis on predictive maintenance, rather than conventional periodic, corrective or preventive maintenance, C.O.M.M. Batt reduces maintenance costs, cuts downtime and associated revenue losses, increases fleet availability and optimizes fleet management. Moving from preventive to predictive maintenance Get the most from your rolling stock battery fleets Implement remote battery performance monitoring Increase the efficiency of maintenance operations Receive advanced warnings to avoid unplanned downtime Optimize operations to save on resources and costs. C.O.M.M. Batt is an innovative step within Saft’s global LCC (Life Cycle Cost) improvement program. It benefits from a specially developed in-built algorithm – based on Saft’s extensive global experience of real-world battery installations – to monitor and evaluate battery status. This algorithm uses data including: • Saft’s proprietary cell models and field data • Temperature, Ah charged and discharged, number of cycles, and current profile

SAFT RAILWAY MAINTENANCE Taking the digital track: rail batteries join the Internet of Things for predictive maintenance at every stage of the journey Before starting Clear indication that the battery has sufficient charge to deliver the required duty profile Real-time indication of battery status and alerts in the event of an emergency Accurate maintenance forecasts, adapted to operator needs Make fully informed decisions Improve productivity Lower maintenance costs C.O.M.M. Batt gives train operators information on the battery system’s ability to perform the defined duty cycle (under worst-case...

Easy to fit and use C.O.M.M. Batt is easy to fit in new or existing applications, for backup or starting. Sensors fitted to each battery measure and transmit key parameters to the C.O.M.M. Batt control unit, which determines the different operation and maintenance indicators, sends real-time alerts if any parameter is out of range and stores operational data. Alert parameter settings can be customized to the operator’s maintenance intervals and strategy. As a standard, C.O.M.M. Batt integrates Ultra Narrow Band (UNB) type wireless or Ethernet interfaces. Different options for data transmission...
