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?
