Beschreibung
Zusammenfassung:	A charge and discharge control apparatus for a secondary battery, which uses feedforward control and feedback control in combination to execute charge and discharge control over the secondary battery, includes: a feedforward control unit that executes the feedforward control; a feedback control unit that executes the feedback control; and a control mode changing unit that changes a control mode between the feedforward control and the feedback control. The feedforward control unit controls at least one of a charging electric power and a discharging electric power on the basis of a predetermined permissible electric power value. When the permissible electric power value is lower than or equal to a predetermined value, the control mode changing unit prohibits the feedforward control, and changes the control mode so as to control at least one of the charging electric power and the discharging electric power through the feedback control.
