In the past, ML in the battery field primarily relied on training, verifying, and predicting data using single models, which is due to the fact that the single model demonstrates strong applicability in addressing battery data under specific conditions, while it unavoidably presents certain limitations.
Learn MoreCurrently, no standard data set from real-world operation exists for battery SOH forecasting models like ImageNet, MNIST, or CIFAR for image classification models (see overview Table 12 in ref. 19).
Furthermore, we investigate a multi-modal deep learning framework to accurately predict the SOH of batteries in EVs leveraging operational data. The approach involves the extraction of multi-modal HIs from a consistent voltage range observed during the charging process of the battery.
By using a dynamic learning rate strategy, the framework achieves remarkably accurate SOH estimations for EV batteries. The MAPE of the SOH estimation results is 2.83%. This result illuminates the potential of the proposed framework for large-scale EV battery evaluation.
Wang et al. 41 proposed a physics-informed neural network for accurate estimation of battery SOH. The results indicated that features extracted from the current and voltage data during the constant current-constant voltage process before the battery is fully charged held promise for accurate SOH estimation.
