Lithium-Ion Battery Capacity Prediction Using Recursive Least Squares with Forgetting Factor

How to predict capacity for lithium-ion battery is one of the most important problems in the field of battery health management. To make the newest data more efficiently, this paper proposes recursive least squares with forgetting factor to estimate the coefficients of the linear capacity degradation model, and presents the adaptive capacity prediction based on the estimation result. The experiment example demonstrates the effectiveness of the proposed approach Keywords-lithium-ion battery; capacity prediction; recursive least squares with forgetting factor; linear degradation model
