PROBLEM TO BE SOLVED: To provide a charge/discharge control device, a battery pack, an electronic apparatus, an electric motor vehicle and a charge/discharge control method, capable of improving a cycle characteristic of a secondary battery while securing the volume energy density of the secondary battery.SOLUTION: The charge/discharge control device includes a circuit configured to control to charge/discharge, by second charge/discharge control, a secondary battery on which charge/discharge is performed under first charge/discharge control. A time variation of the charging rate of the secondary battery when the second charge/discharge control is performed is smaller than the time variation when the first charge/discharge control is performed.
