Explosion-proof pressure-relief fire extinguishing device for battery anti-short-circuit performance test and use method thereof

Abstract

The invention discloses an explosion-proof pressure-relief fire extinguishing device for a battery anti-short-circuit performance test. The explosion-proof pressure-relief fire extinguishing device comprises an explosion-proof box, an explosion-proof box, a battery, a battery anti-short-circuit test mechanism, a controller and a pressure-relief fire extinguishing mechanism, the battery anti-short-circuit test mechanism comprises a control panel, a slide rheostat, a coupling, a speed regulating motor, a starter, a rotary encoder and a current sensor which are arranged in an explosion-proof box, and the pressure relief fire extinguishing mechanism comprises a pressure relief assembly and a fire extinguishing assembly. The invention also discloses a use method of the explosion-proof pressure-relief fire extinguishing device for testing the short-circuit resistance of the battery. The controller controls the speed regulation motor to drive the slide rheostat to adjust the short-circuit current, the battery can be protected, the battery is prevented from burning and exploding in the anti-short-circuit test process, the personal safety of testers and the surrounding environment are protected, meanwhile, the camera can record the change process of the battery in the explosion process, and the safety of the testers is improved. And video playback after an explosion accident is facilitated, and help is provided for battery performance research.

Description

technical field [0001] The invention relates to the technical field of battery short-circuit resistance testing, in particular to an explosion-proof pressure relief fire extinguishing device for battery short-circuit resistance testing and a method for using the same. Background technique [0002] With the development of new energy sources, the application fields of batteries are becoming wider and wider. In order to ensure the safety and reliability of batteries during use, a number of performance inspection tests must be carried out on batteries. Due to market demand, the capacity and energy density of new batteries developed are several times greater than traditional batteries, and their explosive power and destructive power are also much greater than traditional batteries. The short-circuit resistance test of the battery is particularly important in the battery inspection and testing project, and the traditional detection explosion-proof device cannot meet the safety req...
