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 proposed methods in these works [, , , ] are mainly based on the voltage data of a single cell in battery packs, and they cannot accurately diagnose faults and anomalies incurred by variation of other parameters, such as current, temperature and even power demand.
From the detection results and the voltage variation trajectories of cells, it can be concluded that the detected abnormality is a rapid descent of voltage caused by the battery pack that is discharged with a high rate current in a low voltage stage.
The systematic faults of battery pack and possible abnormal state can be diagnosed by one coefficient. For the voltage abnormality, an accurate detection and location algorithm of the abnormal cell voltage are attained by combining the data analysis method and the visualization technique.
With the development of electric vehicles in China, the fault monitoring and warning systems for the charging process of electric vehicles have received the industry’s attention. A method for the monitoring and warning of electric vehicle charging faults based on a battery model is proposed in this paper.
Firstly, the faulty or abnormal battery cells’ voltage is roughly identified and classified using the K-means clustering algorithm . Secondly, the abnormal cell voltage is located based on the designed coefficient that is calculated according to the Z-score theory .

Battery Cabinets. Battery charging cabinets are a type of safety cabinet that''s designed especially for lithium-ion batteries. Over the recent years, as the prevalence of lithium-ion batteries has grown in workplaces, battery cabinets have become more popular due to the many risk control measures that they provide.
Battery abuse faults mainly refer to external short circuit (ESC), internal short circuit (ISC), overcharge and over-discharge. Sensor faults usually indicate abnormal operation of current transducers as well as voltage and temperature sensors, and connection faults are usually caused by loose contact between neighboring cells.
