DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test battery holder for automatic test of battery characteristics, and more particularly to an improvement of an automatic test device for battery characteristics indispensable for evaluation of various batteries.

[0002]

2. Description of the Related Art In recent years, miniaturization of various electronic devices,
Due to higher performance and portability, demand for batteries is increasing. In response, battery improvements and developments are becoming more active. Also, new application areas of batteries are expanding.

[0003] Evaluation by a characteristic test is indispensable for battery development and application to new fields. This is because the characteristics greatly depend on the test conditions. Moreover, those conditions may affect not only the characteristics but also the safety of the battery.

[0004] When developing batteries and applying them to new applications, it is important to conduct battery tests that reflect various conditions actually used as faithfully as possible. However, a test that satisfies them has not been easy because it requires a lot of manpower and equipment.

In particular, with the rapid development of communication devices such as mobile phones, cordless phones, and PHSs and portable home appliances in recent years, not only has the demand for various types of batteries increased significantly, but also commonly used single and single batteries. In addition to AA, AA, and AA, special sizes such as A, 3 / 2A, 5 / 4A, 5 / 4AAA, etc. have increased especially in lithium ion batteries and the like. Correspondingly, several types of battery holders were required to test batteries, which not only increased costs, but also caused considerable inconvenience, such as the need to secure a place to store the parts. .

[0007] An object of the present invention is to provide a test battery holder for an automatic battery characteristic test apparatus capable of coping with a single type of cylindrical batteries of different sizes from single to AAA in order to improve the above-mentioned situation. It is in.
