State of charge (SoC) is a very important parameter for batteries used in EVs. Accurate SoC estimation is pivotal to optimizing battery health, energy management, and driving range reliability in EVs. This study first introduces a Bidirectional Long Short-Term Memory with Loung Attention Mechanism (BiLSTM-LAM) model, achieving high SoC estimation accuracy with 0.73% mean absolute error (MAE), 1.23% root mean square error (RMSE), and a significantly reduced maximum absolute error (MAX) of 4.46%. Leveraging precise SoC predictions, charging and discharging power profiles are dynamically optimized to align with grid conditions, minimizing battery stress. Uncoordinated charging exacerbates power losses and distribution line overloads, increasing operational costs. This study then presents a coordinated charging strategy integrating charging and discharging operations to optimize PEV integration with distribution networks. An optimization model is formulated, balancing operational costs, renewable energy utilization, battery degradation cost, and grid constraints. The model is solved via particle swarm optimization (PSO), demonstrating 40.36–46.86% cost reduction across 10%–30% PEV penetration levels in a 33-bus radial network integrated with solar and wind energy.

The overcharge and thermal behaviors throughout the entire overcharge process are briefly compared and analyzed; the state of charge (SoC) at the onset of thermal runaway and the corresponding overcharge safety limit SoC are determined. Further, the overcharge-induced degradation mechanisms and modes of the three cells at different terminal SoCs are analyzed and compared through incremental capacity analysis (ICA) and electrochemical impedance spectroscopy (EIS) results. Generally, their overcharge tolerances follow this order: cylindrical > pouch > prismatic. Under overcharge conditions, with respect to prismatic cells, the loss of active material (LAM) and the loss of lithium inventory (LLI) modes dominate the aging, whereas in cylindrical and pouch cells, the LLI and the loss of conductivity (LoC) are dominant degradation modes in the cell aging. Moreover, combined with the 3D x-ray computed tomography (XCT) results, the reasons for the distinct overcharge tolerances and failure mechanisms of cells with different packaging forms are elucidated from three perspectives: shell structure, exhaust mechanism, and heat dissipation mechanism.

Numerical simulation demonstrates that the uniformity is worse in MEA near end plates, and the improvement in uniformity realized by the vessel is more pronounced in such regions.
