AI Technical Summary

Technical Problem

Traditional battery consistency assessment methods suffer from low accuracy and cannot effectively monitor the safety and lifespan of energy storage battery systems due to the inconsistent sampling frequencies between cluster-level and cell-level data.

Method used

A method for dividing the detection point interval based on the time of change of cell data is adopted. By acquiring battery cluster data and cell data, different detection point intervals are divided, and the anomaly detection results are analyzed using a prediction model to determine the battery consistency detection results.

Benefits of technology

It improves the timing accuracy and reliability of battery consistency assessment, can comprehensively consider the impact of changes in operating conditions on battery consistency, avoids misjudgment, and enhances the safety and life prediction of battery systems.

Abstract

The application relates to a battery consistency detection method and device, computer equipment and a storage medium. A shot interval division method taking a battery cell data change moment as a reference is adopted, a time mismatch problem caused by inconsistency between cluster level data and battery cell level data sampling frequencies in a traditional method is solved, different level data can be aligned and fused on a unified time axis, and therefore, time accuracy of battery consistency evaluation is improved. Cluster level features reflecting energy storage system operation conditions and battery cell level features reflecting individual differences of battery cells are extracted, influence of operation condition changes on battery consistency can be comprehensively considered, battery cell abnormities are avoided from being misjudged as operation condition fluctuations, and reliability of battery consistency evaluation is improved.
