Kexun Battery Needling and Extruding Machine

Short Description:

Power Battery Extrusion and Needling Machine is an essential testing equipment for battery manufacturers and research institutes.

It examines the safety performance of the battery through extrusion test or pinning test, and determines the experimental results through real-time test data (such as battery voltage, maximum temperature of battery surface, pressure video data). Through the real-time test data (such as battery voltage, battery surface temperature, pressure video data to determine the results of the experiment) after the end of the extrusion test or needling test battery should be No fire, no explosion, no smoke.

Application

1.Installation of lighting tube, outside the studio can clearly see the situation; needling / extrusion speed 10 ~ 80mm / s can be adjusted; - Needling / extrusion force value

2.The needling/extrusion force values can be set at any customised level to meet different standard requirements. Wire coat metal fire pipe, effectively prevent the battery test process of ignition and combustion phenomena; separation of control and test box with form, available at 1~2 meters operation, be safe.

Squeeze: The test cell is squeezed in two planes, and a squeezing pressure of about 13KN is applied through a vise or a hydraulic arm with a piston diameter of 32mm, the squeezing continues until it rises, and once the maximum pressure is reached, the squeezing is lifted.

Needling: The test shall be carried out at an ambient temperature of 20℃±5℃, the battery connected with a thermocouple (thermocouple contacts are fixed on the surface of the battery) is placed in a fume cupboard, and a non-corrosive 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 and held for an arbitrary period of time. center of the largest surface of the cell at a speed of 10mm/s-40mm/s and hold it for an arbitrary period of time.
