Detecting Changes in Readings from Remote Battery Systems

摘要

Uninterruptable Power Supply (UPS) systems are essential in modern-day industry to ensure that equipment continues to function even in the event of power failure. These UPS systems must themselves be resistant to failure to guarantee that they will be working when necessary. Because monitoring and maintaining these UPS systems is beyond the scope of many industries, it is contracted out to firms that manage systems at hundreds of installations nationwide. These companies require automated monitoring tools to use sensor data (collected by instruments installed on the UPS systems) to determine when batteries are in need of replacement. In this paper, we present a case study using real-world battery data demonstrating the use of a tool for detecting unusual behavior in battery resistance readings, such as those indicative of impending or recent battery replacement. This tool will allow practitioners to identify when upgrades have not been properly recorded, or as part of a larger system for autonomous monitoring and managing of battery systems.
