Abstract

The present invention provides a battery test device. The battery test device (10) is a device for testing a battery arranged in a test tank, and comprises: a compressing plate (16) used for pressing the battery (B) when a crush test is performed for the battery (B); and a driving unit (18) for generating a driving force used for moving the compressing plate (16). A clamp used for a nail penetrating test can be installed at the compressing plate (16). Accordingly, the burden of test preparation operation can be reduced.

Description

technical field [0001] The invention relates to a battery testing device. Background technique [0002] Conventionally, a battery testing device for evaluating battery safety as disclosed in Japanese Patent Publication No. 4408058 is known. In the battery testing apparatus disclosed in Japanese Patent Publication No. 4408058, a flat plate or square is mounted on the top end of a rod to be driven when the battery is subjected to a crush test. The cell is pressed by a flat or square bar through the drive rod. On the other hand, when a battery is subjected to a nail penetration test, a nail is mounted on the tip of the rod. Through the drive rod, the battery is spiked. As a result, an internal short circuit of the battery is caused. [0003] In the battery testing device disclosed in Japanese Patent Publication No. 4408058, when performing a squeeze test or a nail penetration test on the battery, it is necessary to remove the member mounted on the top of the rod and replace...
