Researchers have developed C2L-Net, a novel data-driven framework designed for efficient and accurate state-of-charge (SOC) estimation in lithium-ion batteries. This new model addresses limitations of existing methods by using a significantly shorter historical window (20 seconds) and separating contextual encoding from the latest measurement updates. C2L-Net integrates chunk-based feature extraction with Theta Attention Pooling and a Fourier-based Seasonality Basis, alongside a causal context encoder using a gated recurrent unit and Causal Cosine Attention. Experiments show C2L-Net achieves state-of-the-art accuracy while being up to 60 times faster and requiring fewer parameters than previous baselines, demonstrating robust performance on unseen driving profiles.
