As discussed above, the faults diagnosis and abnormality of battery pack can be detected in real time. In addition, timely detection and positioning of faults and defects of cells can improve the health and safety of the whole battery pack.
By applying the designed coefficient, the systematic faults of battery pack and possible abnormal state can be timely diagnosed. 2) The t-SNE technique, The K-means clustering and Z-score methods are exploited to detect and accurately locate the abnormal cell voltage.
However, the current large-scale battery pack monitoring systems exhibit certain design flaws: (1) wired communication leads to cable harness problems such as connection failure, high cost, heavyweight, and complex design; and (2) insufficient monitoring data, preventing timely warnings [ 11, 12, 13 ].
Through comprehensive analysis of operation data of the battery pack in E-scooters, we use the statistical technology to analyze the distribution characteristics of each parameter in battery packs and design the abnormal state detection coefficients.
However, misdiagnosis and missed diagnosis happened occasionally. In this paper, a statistical analysis-based multi-fault diagnosis method is proposed to detect and localize short circuit faults, electrical connection faults and voltage sensor faults in LFP battery packs.
Therefore, the proposed method for voltage fault diagnosis can detect the aberrant battery cell accurately in a timely manner, thereby enabling great significance to prognosis and safety management of future battery failures. In this study, a large amount of voltage data are analyzed based on the Gaussian distribution.
