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, IEC 62133, IEC 60086-4:2000, QC/T 743-2006, QC/T 744-2006.

Nail Penetration Test Chamber for Lithium Ion Battery, Lithium Batteries

The structure design of the Wewon Tech’s nail penetration test chamber is advanced and reasonable, the manufacturing process is standard, and the appearance is beautiful and generous. The main functional components of the crush & nail penetration system are equipped with world famous brand, advanced and reliable technical principles, and the best control of noise and energy saving — its performance can replace similar foreign products.

The matching of parts and components is good, and the main functional components are imported with the international advanced level, which improves the safety and reliability of products and ensures the users’ requirements of long time and high frequency. The nail penetration test chamber for lithium ion battery, lithium batteries has good operation, maintenance, good temperature stability and durability, good safety performance, no pollution of the environment and harm to human health. All the wires in the control cabinet have the serial number and number printed by special equipment, and the lines are clear and clear at a glance.

The battery is squeezed between the two plates. The extrusion pressure is applied by a hydraulic head with a 32 mm diameter piston. The pressure reading on the hydraulic head reaches 17.2Mpa and the acting force is about 13 KN. Once the maximum pressure is reached, the pressure can be relieved.
The cylindrical ring prismatic cell shall be subjected to extrusion with its longitudinal axis parallel to the plane of the extrusion device. The prismatic cell also needs to be rotated 90° around its vertical axis so that the wide and narrow sides can withstand extrusion pressure.
Each sample cell is subjected to pressure in only one direction. Different samples should be used for each test. Coin or button type battery, the battery plane should be parallel to the extruder plane under extrusion pressure.
