AI Customer ServiceDue to the complex nature of batteries, determining the cause of a failure of a battery-powered device may require expert knowledge across several scientific and engineering areas. Failure analysis is the process of collecting and analyzing data to identify the root cause of a failure.
In essence, a battery failure analysis involves data collection, analysis of the data, and proving that the true root cause has been found by demonstrating the ability to create and eliminate the problem at will. Situation appraisal: A general term describing the need to fully understand the failure and what is being requested.
Extensive testing with real-world data demonstrates the potential for accurate battery cell failure diagnosis and thermal runaway cell localization. Recently, a research introduces a real-time fault detection method using Hausdorff distance and modified Z-score , particularly for internal short-circuit faults in battery packs.
Battery-powered devices can fail for a number of reasons: battery/cell failure, device malfunction (external to the battery), or failure of the battery management control system integrated into the battery itself or through separate circuitry designed into the device.
In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions. At present, model-based fault diagnosis methods are still the hot spot of research.
They analyze the mechanisms of battery faults, classifying them into mechanical, electrical, thermal, inconsistency, and aging faults, and use model-based, data-driven, and knowledge-based methods for fault diagnosis. Battery faults are primarily indicated by changes in voltage, current, temperature, SOC, and structural deformation stress.
