Then, it is assumed that aging effects are time-varying. Therefore, the fault detection scheme can detect faults of new battery cells as well as aged cells. Some simulations have been conducted on a Lithium-ion battery cell and extended to battery pack, to demonstrate the performance of the proposed approach in more real-world scenarios.
This study compared two nondestructive testing methods, SAM and CT, for the detection and 3D localization of defects in battery cells. It is important to detect such defects before performance degradation or safety issues arise.
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.
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.
Different fault detection approaches based on model, signal-processing, or knowledge can be applied for the battery. The model-based approaches consider an electrochemical model or an equivalent circuit model, to detect faults.
For this investigation, it was important to use components with controlled and known defects at defined positions inside the pouch cells. In order to make the battery cell as realistic as possible, electrodes sheets and separator foils extracted from commercially available cells were used.
