New Energy Battery Acupuncture and Extrusion All-in-One Machine

This machine is suitable for simulating the needling of various batteries in the process of transportation and storage. The test should be carried out at the ambient temperature of 20℃±5℃. 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 corrosionless steel needle with a diameter of 2-8mm is used to Pierce the central position of the largest surface of the battery at a speed of 10mm/s~40mm/s. Keep any time and observe the test results of the battery does not explode, do not fire is qualified.
