Description

Introduction:
Power battery extrusion needling machine is an essential testing equipment for all battery manufacturers and research institutes. It tests the safety performance of the battery through the extrusion test or the needling test, and determines the experimental results through real-time test data (e.g. battery voltage, maximum temperature of the battery surface, pressure video data). The battery should not catch fire, explode or smoke after the squeeze test or the needling test.

Standards:
        18897.4-2002, SJ/T 11170-1998, YDB 032-2009, UL 2054, QB/T 2502-2000, QB/T 31485-2015, QB/T 31486-2015, GB/T 31467.3-2015, GB/T 18332.2-2001, MT/T 1051-2007
Principle of operation:
        Squeezing: The test cell is squeezed in two planes by applying a squeezing pressure of approximately 13KN through a vise or piston with a 32mm diameter hydraulic arm, the squeezing The squeezing pressure is continued until it rises and once the maximum pressure is reached, the squeezing is released.
        Needling: The test should be carried out at an ambient temperature of 20°C ± 5°C. The cell connected to a thermocouple (the contacts of the thermocouple are fixed to the large surface of the cell) is placed in a fume hood. surface) in a fume hood and pierce the largest surface of the cell with a non-corroding steel needle of 2-8 mm diameter at a speed of 10 mm/s to 40 mm/s. centre and hold for any length of time.
Features:
-Lighting tube for clear view of the workshop from outside; Needling/extrusion speed 10~80mm/s can be adjusted at will.
-The needling/extrusion force value of 250N~13KN can be set at will to meet different standards.
-Test hole and air outlet, air outlet + exhaust fan will be more effective in removing the test exhaust and air pressure; test hole is designed for testers who want to detect the temperature or air pressure in the test space.
