Scope of application
Battery needling extrusion machine, this machine is suitable for simulating the needling of all kinds of batteries in the process of transportation and storage. The test should be carried out at an ambient temperature of 20ºC±5ºC. The battery connected with the thermocouple (the contact of the thermocouple is fixed on the large surface of the battery) is placed in the ventilator, and a rust-free steel needle with a diameter of 2-8mm is used to Pierce the center of the largest surface of the battery at a speed of 10mm/s~40mm/s. Keep it for any time and observe the test result that the battery does not explode or catch fire.
| 1. Product overview | |||||||||
| Test purpose | This machine is suitable for simulating the extrusion and needle puncture of various types of batteries when they are used, transported, stored or disposed of household waste. The battery is qualified if it does not explode or catch fire. | ||||||||
| Description of extrusion test methods | The test should be carried out at an ambient temperature of 20ºC±5ºC. Place the fully charged battery in two planes and squeeze the battery perpendicular to the direction of the plate with a squeezing force of 13KN±0.78KN. Once the pressure is high* If the value is large, the extrusion test can be stopped. During the test, the battery does not have an external short circuit. The tested battery is qualified if it does not explode or catch fire. | ||||||||
| 1). For cylindrical batteries, the longitudinal axis of the extruded battery should be parallel to the two flat plates of the extrusion device. 2). For prismatic and soft-pack batteries, only the wide surface of the battery is subjected to the extrusion test. 3). For coin-type or button-type batteries, perform the extrusion test with the upper and lower planes of the battery parallel to the flat plate. | |||||||||
