PROBLEM TO BE SOLVED: To automate calibration to shorten a calibration/adjustment time, resolve human errors, and simplify works, and thereby, to enable improvement of a quality of a charge and discharge test and the like.SOLUTION: With respect to a charge and discharge testing device 1A having a plurality of charge and discharge power supplies 41-4n, and charging and discharging each charge and discharge power supply from and to a secondary battery of a charge and discharge testing target by means of a controller 3 to perform a charge and discharge test of the secondary battery, a calibration device 20 calibrates each charge and discharge power supply 41-4n. This calibration device 20, at calibration of the charge and discharge power supply to be a calibration target, utilizes the charge and discharge power supplies other than the calibration target as a DC power supply and/or a resistive load. |
