Overview

Deep learning evaluation demonstrates robust state of health estimation in lithium-ion batteries, indicating viability for real-time embedded management systems.

Key Points

Develop a multi-scale spatiotemporal deep learning architecture to accurately estimate lithium-ion battery degradation from noisy, nonlinear charging signals.
Constructed a multi-scale convolutional neural network integrated with an attention-enhanced bidirectional long short-term memory network (MS-CNN-BiLSTM).
Applied a degradation-aware sliding-window strategy to capture multi-scale aging representations from battery charging curves.
Tested and validated model performance across distinct battery chemistries using open-source NASA LCO and MOLICEL NCM datasets.
Achieved high estimation accuracy with mean absolute error (MAE) values as low as 0.0026.
Reached coefficient of determination (R2) values above 0.979 across varying degradation profiles.
Maintained stable performance across different chemistries with low computational overhead suitable for embedded systems.
