New method improves nonlinear model parameter estimation for battery health prediction

A new paper introduces a regularized iterative generalized least squares method for identifying nonlinear phenomenological models, particularly useful in fields like state of health prediction for lithium-ion batteries where parameters can be difficult to estimate reliably. The method incorporates an automated approach to optimize a ridge regression hyper-parameter at each iteration using information-theoretic measures, demonstrating rapid convergence. This technique is designed to handle heteroscedastic and serially correlated data, with simulations confirming its effectiveness. AI

IMPACT This methodology could improve the accuracy of predictive models in various scientific and engineering domains, potentially impacting AI applications that rely on accurate parameter estimation from experimental data.
