多应力作用下锂离子电池老化模型
Aging models of lithium-ion batteries under multiple factors
摘要
Abstract
A second order polynomial aging model was proposed to describe the relation between cell aging rate and five main factors.Quadratic regression orthogonal design of experiments with 28 groups of tests was applied to fit the parameters in the model.The applicability of the model was validated using four additional experiments.An empirical model in the form of Arrhenius was put forward after further screening of the factors.The parameters were fitted and the applicability of the model was validated by the data from the quadratic regression experiments.关键词
