Abstract
This work investigates the modeling of lithium-ion batteries (LIBs) with a recurrent neural network (RNN), rather than with an equivalent circuit or similar type model as is typically used. The RNN is trained with dynamic battery data, such as vehicle drive cycle test results. Specialized characterization tests and model parameterization are not necessary, simplifying the process of battery modeling. A compact unified methodology consisting of an RNN with gated recurrent unit and deep feature selection structures is utilized. A total of two RNNs are evaluated, one with current as the input and another with power as the input. Both RNN forms accurately model LIB dynamic responses including battery nonlinear behavior at different temperatures. The models are compact in size, require fewer characterization tests compared to conventional equivalent circuit models, and can be further used as an LIB simulator in model-based design and hardware-in-loop applications to test battery management systems and other electronic components.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
