6 FAQs about [Energy storage cell abnormality]
What causes abnormal battery voltage data?
Such abnormal voltage data occur because the battery has experienced over-charging, over-discharging, imbalance, thermal runaway, and other faults [5, 6], causing voltage changes abnormally. Consistency anomaly detection of the battery voltage can help to achieve early warning of battery faults and avoid safety accidents in energy storage stations.
Why do we remove abnormal data from EV data?
The abnormal data at or near battery failures are removed so that successful predictive models need to identify battery problems at least days ahead based on historical data. They may also be used for tasks beyond anomaly detection such as battery capacity degradation prediction. Fig. 1: EV dataset and challenges in fault detection.
Can Cell 47 & 31 detect abnormal cells before battery failure?

How accurate is the capacity-resistance-based method for identifying abnormal batteries?
Our method can accurately identify all abnormal batteries in the dataset, with a false alarm rate of only 3.8%. The overall accuracy achieves 96.4%. In addition, we find that the widely used capacity-resistance-based methods are not suitable for identifying lifetime abnormality, which must draw enough attention from the battery community.
Why is voltage anomaly important in battery anomaly detection?
Many existing studies have shown that when there are various abnormal faults in the battery, the voltage of the battery exhibits more pronounced fluctuations compared to other data during abnormal conditions. Therefore, voltage anomaly is an extremely important fault indicator in battery anomaly detection.
