Battery test extrusion platform

Abstract

The invention provides a battery test extrusion platform. The battery test extrusion platform comprises a bottom plate, a pressure strain gauge baffle, a force application plate, a stud fixing plate,a force transmission plate, a spring and a stand column which are sequentially arranged from top to bottom. Receding holes are symmetrically formed in the bottom plate, the pressure strain gauge baffle, the force application plate and the force transmission plate around the center; the receding holes in the bottom plate, the pressure strain gauge baffle, the force application plate and the force transmission plate are in one-to-one correspondence up and down; the stand column sequentially penetrates through receding holes in the bottom plate, the pressure strain gauge baffle, the force application plate and the force transmission plate. A to-be-tested battery is arranged between the stud fixing plate and the force application plate; the stand column between the force application plate andthe force transmission plate penetrates through the spring; and a central force application device is arranged at the central position of the force transmission plate. By applying the technical scheme, the accuracy of the battery pressure test can be realized based on a simple platform structure.

Description

technical field [0001] The invention relates to the field of battery testing, in particular to a battery testing extrusion platform. Background technique [0002] As people pay more and more attention to the environment, new energy drives are increasingly favored by the public. Lithium batteries have become the core of new energy drives due to their advantages such as high energy density, environmental friendliness, and long service life. One, and its safety is also the most concerned by the public. With the large number of batteries put into use, safety accidents are constantly increasing, such as the explosion of mobile phone batteries, and the fire of new energy vehicles. In order to test the safety of the battery under certain conditions, it is necessary to design a device that can apply pressure to the battery to evaluate the safety of the battery. At present, the pressure test of batteries on the market generally uses expensive pressure testing machines, which has ca...

AI Technical Summary

Problems solved by technology

At present, the pressure test of batteries on the market generally uses expensive pressure testing machines, which has caused some small institutions to give up the safety testing of this item. In addition, some cheap and simple pressure devices can meet the requirements of battery testing in principle. pressure, but they cannot guarantee the consistency of pressure on the same plane of the battery, resulting in inaccurate test results
