The battery needle punching test machine is used for testing the squeezing and needle punching performance of electric vehicle power batteries. According to the standard requirements, the needle
punching device must meet the operating speed of the steel needle to meet various test requirements; So the adjustment of the steel needle speed adopts a programmable scheme, with a customized
range of 0-30mm/s and adjustable speed. The commonly used needle speed is (25 ± 5) mm/s.
The main technical parameters of the battery needle puncture testing machine are:
1. Case structure: double-layer box structure, inner box: SUS # 304 stainless steel plate, 2/3 of the box is covered with PTFE tape for easy cleaning
2. Outer box: cold-rolled steel plate painted, box door with explosion-proof glass and observation window for easy observation;
3. Working voltage: AC 380V 50Hz 3KW;
4. Drive mode: Hydraulic system drive, single oil cylinder.
5. Pressure control: controlled by an electro-hydraulic servo valve.
6. Working oil pressure: 10Mpa;
7. Maximum single oil pressure stroke: 1500mm.
8. Needle size: Ф 5mm to ф 10mm high-temperature resistant steel needle can be replaced;
