Battery pack extrusion needle punch testing machine

This machine is suitable for simulating the needling of various types of batteries during transportation and storage. The test should be carried out at an ambient temperature of 20 °C ± 5 °C. The battery connected with the thermocouple (the contact of the thermocouple is fixed on the large surface of the battery) is placed in a fume hood. The needle pierces 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 results, if the battery does not explode or fire, it is qualified.
