Abstract
A charging apparatus includes a control unit configured to determine an average ion concentration, a surface ion concentration and a solid phase potential for anode particles and an electrolyte potential in an anode, using a predefined electrochemical reduced order model. The control unit is further configured to determine a side reaction rate from the solid phase potential and the electrolyte potential. The control unit is further configured to reduce the magnitude of the charging current applied to a secondary battery based on at least one of a cutoff voltage, the surface ion concentration and the side reaction rate.
