Measuring and Analysis of Nonlinear Characterization of Lithium-Ion Batteries Using Multisin Excitation Signal

Year: 2016

Type: article

Abstract: This paper introduces a novel methodology for analysis in the frequency domain. This methodology looks to the battery from a different point of view and covers aspects of the battery that is often neglected in other works and analysis battery precisely. Using periodic signals such as random phase multisine for system identification, allows separating noise and nonlinear distortions from the linear part of the system’s response. In addition to a shorter test time in comparison with conventional single sine EIS, by performing extra periods and different phase realizations, transients are eliminated and noise disturbance and also nonlinear distortion is detected.
