Abstract

Accurate prediction of the reversible capacity and remaining useful life (RUL) of Li-ion batteries (LiBs) is crucial for effective battery management strategies. This paper combines a bimodal decomposition algorithm with a Long Short-Term Memory (LSTM) network for LiB capacity and RUL prediction. First, battery health features and capacity degradation trends are decomposed with the Complementary Ensemble Empirical Mode Decomposition (CEEMDAN) and subsequently clustered using the k-means method to identify modal components. Then high-frequency components are further decomposed using Variational Mode Decomposition (VMD), optimized with the Symbiotic Organisms Search (SOS) algorithm. These processed features are then fed into the LSTM model to construct their relevance with respect to capacity and RUL. Finally, comparative experiments using the NASA dataset demonstrate that the proposed method outperforms other mainstream approaches, particularly in capturing the capacity regeneration interval, showcasing its superior prediction accuracy.
