A model with a single encoder (temporal-wise) may struggle with the complexity and the multi-dimensional nature of the data in large-scale EV applications. Such a model tends to be insufficient in isolating channel-specific information and temporal dependencies simultaneously, leading to less accurate fault predictions.
Here, we proposed to solve this issue by “creating” more abnormal data. The aim of this work was to use the data collected from the first cycle of the aging test to identify the lifetime abnormality. However, as shown in Figure 1 and many other battery aging datasets, [22, 35, 36] the battery's behaviors in the first few cycles were highly similar.
The use of improved Lyapunov exponent method to detect abnormal changes in battery data has a stable effect on different levels of abnormal conditions. The proposed multi-fault coding method can use unified coding to characterize different fault scenarios, and has good robustness.
Verified with the largest known dataset with 215 commercial lithium-ion batteries, the method can identify all abnormal batteries, with a false alarm rate of only 3.8%. It is also found that any capacity and resistance-based approach can easily fail to screen out a large proportion of the abnormal batteries, which should be given enough attention.
Therefore, developing a reliable and efficient early warning model for battery failures is not just about selecting an optimal embedding time. It also necessitates understanding the nature and severity of potential faults and the anticipated prediction tasks. This knowledge is as crucial as the selection of embedding time.
This work proposes a lifetime abnormality detection method for batteries based on few-shot learning and using only the first-cycle aging data. Verified with the largest known dataset with 215 commercial lithium-ion batteries, the method can identify all abnormal batteries, with a false alarm rate of only 3.8%.
