Nail penetration test chamber is an indispensable testing equipment for battery manufacturers and research institutes. The nail penetration test chamber is suitable for simulating the use, transportation, storage or disposal of household waste of various kinds of batteries, the condition in which the battery is pinched and pricked, The test shall be conducted at an ambient temperature of 20℃±5℃, Place the battery connected to the thermocouple in the fume hood, The thermocouple contacts are fixed on the large surface of the battery.
A non-corrosive steel needle with a diameter of 2mm to 8mm is used to pierce the center of the largest surface of the battery at a speed of 10mm/s ~ 40mm/s, Hold it at any time and observe the test results, If the battery does not explode or catch fire, it can be judged as qualified product. The safety performance of the battery shall be tested through crush and nail penetration test. After the test, the battery shall not catch fire or explode.

Extrusion test for nail penetration test machine: The battery under test was squeezed between two surfaces, Through pliers or pistons, About 13KN extrusion pressure is applied to the 32mm diameter hydraulic arm, The squeeze continues until the pressure gauge reading on the hydraulic device reaches 17.2Mpa, Once the maximum pressure is reached, the squeeze is lifted. For cylindrical batteries, squeeze the long shaft of the battery, It shall be parallel to the extrusion plane of the extrusion device.
For prismatic cells, The pressure shall be applied in one of two directions perpendicular to its long axis, And then squeeze in the other direction. For the button cell, extrude its plane. Each battery tested needs to be squeezed only once. Test standard for Wewon’s nail penetration test chamber comply with SJ/T 11169 (equal to UL 1642:2008), SJ/T 11170 (equal to UL 2054:2008), UL 1642, GB8897.4 2002 6.3.2.9, IEC 62133, IEC 60086-4:2000, QC/T 743-2006, QC/T 744-2006.
