Koopman operator-augmented physics-informed neural network with SEI kinetics for stable and explainable SOH estimation in battery packs
A Koopman Operator-Augmented Physics-Informed Neural Network (Koopman-PINN) tailored for battery pack SOH estimation, which embeds the nonlinear SOH degradation into a high-dimensional Koopman observation space where it evolves linearly.
