Abstract:

This study takes the issue of internal faults in lithium batteries as the starting point and proposes an internal fault analysis strategy for lithium batteries based on the Isolation Forest algorithm. It not only explains the impact of lithium battery faults on their operational safety, but also explores the feasibility of applying the Isolation Forest algorithm. Analyze the necessity of fault data collection and preprocessing, and based on this, construct an isolated forest algorithm model. Then, elaborate on the effectiveness of the designed method from three aspects: anomaly score calculation, fault determination, and fault diagnosis.
