Abstract
Battery-cell hysteresis has crucial impact to battery-management system (BMS) performance. Improved hysteresis modeling accuracy can improve state-of-charge (SOC) estimation. This paper proposed using a linear least-squares method to identify a Preisach weight function and using the discrete Preisach model to estimate hysteresis for a Li//Si half cell. We found that the discrete Preisach model gives acceptable hysteresis-error estimates within 5% with resonable levels of discretization of 50.
