The approach promises significant cost reduction for the monitoring system compared to a distributed electrical sensing system. Furthermore, due to coherent reception a high sensitivity can be reached, which can be further improved by combining with machine learning algorithms for detection and classification.enBattery monitoring | machine learning | OTDRMLE@TUHHTechnology::600: TechnologyConference Paper10.1109/PEDG54999.2022.9923150Conference Paper
