Therefore, timely and accurate detection of abnormal monomers can prevent safety accidents and reduce property losses. In this paper, a battery cell anomaly detection method is proposed based on time series decomposition and an improved Manhattan distance algorithm for actual operating data of electric vehicles.
The experimental method for studying defective batteries typically involves the following steps: preparing defective batteries, conducting battery aging and charge-discharge tests, and performing disassembly for observation and analysis.
Improving the safety of batteries is a systematic project, and at a time when there has been no breakthrough in the chemical system, improvements, such as build a practical graded warning system, are needed in all aspects of design, production, use and disposal to improve battery safety and minimize the risk of failure. 1. Introduction
Thermal abuse mainly includes abnormal temperature (AT) [3, 4], e.g., overheating and extremely low temperature. All the faults of the three abuse conditions threaten the safety of lithium-ion batteries; as such, diagnosing the battery fault accurately and in a timely manner plays a key role.
Volume 7, article number 35, (2024) Lithium-ion batteries (LIBs) are susceptible to mechanical failures that can occur at various scales, including particle, electrode and overall cell levels.
When the malfunction worsens, the degree of abnormality in the battery will rapidly evolve, ultimately leading to safety accidents. Therefore, we need to detect abnormal cells within the battery pack before the battery fault deteriorates.
