ABSTRACT:
The present invention provides a battery testing device and a battery testing method which can appropriately verify the behavior of a battery when damage occurs. Appropriately verification of battery behavior in a case of battery damage has not been achieved since a completely crushed state of a battery almost never occurs during the sue of a portable device, such as a portable telephone, and a completely crushed state of a battery is not the worst condition when determining an abnormality induced by an internal short. Therefore a secondary battery set on a test stand is partially crushed using a pressing member, and the quality of the secondary battery is determined by measuring the temperature of the secondary battery, whereby battery behavior when the secondary battery is damaged can be appropriately verified.
