Battery Acupuncture Extrusion Test Chamber/Battery Acupuncture Extrusion Puncture Integrated Testing Machine

The Chamber is used for the acupuncture/extrusion test of the battery/battery pack, simulates the detection of local thermal runaway or internal short circuit that may be caused by the extrusion force or foreign object penetration of the battery product.

Test method description
The test should be carried out at an ambient temperature of 20ºC±5ºC. Place the battery connected with the thermocouple (the contacts of the thermocouple are fixed on the large surface of the battery) in a fume hood and cover it with a non-corrosive steel pipe with a diameter of 2-8mm. The needle pierces the center of the largest surface of the battery at a speed of 10mm/s-40mm/s and maintains it for any time.

 
The battery extrusion and acupuncture testing machine is suitable for simulating various types of batteries to test their safety performance through extrusion tests and acupuncture tests. After the test, the battery should not catch fire or explode. It is also a must for all battery manufacturers and research institutes. Less testing equipment.
 
Features of Battery Test Chambers:
Automatic explosion-proof pressure relief device, smoke exhaust device, fire extinguishing device, emergency stop switch, etc. After the box is designed to have an outlet, the professional car battery tester is equipped with lighting.
