<p>A method of inspecting a secondary battery includes: discharging the secondary battery initially charged, at a discharge current, from an initial voltage to a discharge ending voltage; calculating an interval capacity in a voltage interval from a check starting voltage to a check ending voltage, based on the discharge current, and discharge time taken in the voltage interval; measuring a voltage change amount from a point in time when the voltage reaches a first voltage to a point in time when a length of time elapses from the above point in time, when the secondary battery is discharged from the initial voltage to the discharge ending voltage; and determining whether a total capacity satisfies a performance requirement, by comparing the calculated interval capacity with a first threshold value, and determining whether an output satisfies a performance requirement, by comparing the measured voltage change amount with a second threshold value.</p> |
