PROBLEM TO BE SOLVED: To develop a testing device capable of keeping a temperature of an object under test within a desired temperature range even if the object under test generates heat, and to provide a secondary battery evaluation method capable of accurately evaluating performance and characteristics of a secondary battery after a charge/discharge test.SOLUTION: A testing device includes: a test room 2 covered with an adiabatic wall 5; whole temperature regulation means 28; a plurality of auxiliary heating sources 17; and a plurality of target-temperature measuring means 20 measuring temperatures of secondary batteries 50, respectively. The test room 2 is partitioned into a plurality of object-under-test placement rooms 11a to 11f in which the secondary batteries 50 are installed, respectively. The whole temperature regulation means 28 includes a main heating source 21 and a main blower 22, and can supply air regulated to have a predetermined temperature to the object-under-test placement rooms 11a to 11f in the test room 2. The auxiliary heating sources 17 regulate the temperatures of the respective object-under-test placement rooms 11a to 11f so that the temperatures of the respective secondary batteries 50 are equal to the predetermined temperature, on the basis of the temperatures detected by the target-temperature measuring means 20. |
