A hybrid model based on black-winged kite algorithm and dual-attention mechanism optimized temporal convolutional network (TCN) with simple recurrent unit (SRU) is proposed to improve the accuracy of online remaining-useful-life (RUL) prediction for Li-ion batteries (LIBs). Health indicators (HIs) correlated battery capacity are extracted from calculated variables verified Spearman correlation coefficient constructed, applying TCN multi-head self-attention capture in spatial dimension decay pattern HIs, introducing attention ability SRU timing patterns input sequences as well BKA further optimize hyper-parameters, enhancing performance. Experimental data used validate model’s predictive performance LIBs at different usage levels under complex conditions such regeneration, sharp fluctuations, plunges. The results achieve MAE less than 3.66%, MAPE below 2.02%, RMSE not exceeding 5.03%, R 2 greater 0.96, absolute error RUL 5. experimental demonstrate that can accurate perform good robustness.

To accurately predict the state of health (SOH) lithium-ion batteries and improve safety reliability battery management systems, a new SOH estimation method based on fusion features (HFs) adaptive boosting integrated grey wolf optimizer to optimize back propagation neural network (Adaboost-GWO-BP) is proposed. First, five kinds multi-type HFs were extracted from charging process, correlation between proposed was verified by Pearson Spearman coefficients. Then, indirect feature (IHF) obtained multidimensional scaling dimensionality reduction reduce data redundancy SOH. The GWO-BP model then used establish nonlinear mapping relationship IHF In order overcome problem low accuracy in single model, Adaboost algorithm ensemble learning introduced enhance estimation. Finally, NASA dataset, compared with other models. comparative experiments, mean absolute error root square for less than 0.81% 1.26%, which has higher

Abstract The state of health (SOH) lithium-ion batteries is a crucial parameter for assessing battery degradation. aim this study to solve the problems single extraction features (HFs) and redundancy information between in SOH estimation. This article develops an estimation method based on multifeature fusion Bayesian optimization (BO)-bidirectional gated recurrent unit (BiGRU) model. First, total eight HFs three categories, namely, time, energy, probability, can be extracted from charging data accurately describe aging mechanism battery. Pearson Spearman analysis verified strong correlation SOH. Second, multiple principal components obtained by kernel component (KPCA) eliminate HFs. with highest selected bicorrelation defined as fused HF. Finally, improve accuracy, BO-BiGRU model proposed. proposed validated using datasets NASA. results show that accuracy high, while mean absolute error (MAE) lower than 1.2%. In addition, lithium estimated different proportions test sets, root-mean-square (RMSE) percentage (MAPE) remain within 3%, high robustness.
