    Abstract: A control device for measuring the capacity of a lithium ion secondary battery without inconveniencing the user of the secondary battery, wherein the control device controls operations for a plurality of charge and discharge cycles comprising charging of the secondary battery and discharging of the secondary battery following thereafter. The control device acquires a first voltage which indicates the maximum voltage value in a first charge/discharge cycle, a discharge end voltage which indicates a voltage in the period between the end of discharge in the first charge/discharge cycle and the start of the next charge, and a reference voltage which indicates a voltage at which capacity measurement of the secondary battery is started. When the discharge end voltage is higher than the reference voltage, a second voltage which indicates the maximum voltage value in a second charge/discharge cycle, which is the next cycle after the first charge/discharge cycle, is set lower than the first voltage.
