Lithium Battery Nail Penetration and Crush Squeeze Test Equipment 

Application  

Through real-time test data ( battery voltage, max, battery temperature, pressure voltage data) to test battery safety performance by crushing & nail-penetration and judge test result on the condition of no flame, smoke, explosion after test.                                                      

Function description

Power battery crush and puncture test machine has up to 50KN-5000KN pressure, Driving a large stroke cylinder by an independent hydraulic system , oil cylinder drive the extruding plate to do the test of the extruding and deformation of the battery. The test panel can be adjusted up and down slightly to obtain the best test position.
It could do both piercing and extrusion, and can provide different extrusion deformation and duration according to the set program. 
In the work, the corresponding program can be selected according to the purpose of the test, and  get the test date you need.

4)needles used in the module experiment are two forms (a) for independent steel needle, (b) and (c) for parallel structure.The separation distance of needles must be adjustable and the adjustable range is between 100mm-250mm.

Process Performance
1. Four columns horizontal pressure structure, maximum 200KN pressure, could pierce the battery.
2. 800mm oil pressure stroke, operation speed can be adjusted automatically.
3. The test platform has large space, large scope of application and can accommodate multiple batteries at one time.
4. Test platform can be up and down (0-300mm) to obtain different placement height, bearing 300KG. the platform size 800*500mm.
5. Pressure Control Accuracy:±1%.
6. Displacement control Accuracy:±1%.
7. Voltage Control Accuracy:±1%FSR.
8. Temperature Accuracy: ±1ºC; Temperature  Resolution: 0.1ºC( automatic acquisition function)
9.Displacement control Speed:0mm/s~25mm/s(Automatic speed regulation of proportional valve)
10.Auxiliary function: temperature acquisition (temperature range 0ºC~1200ºC), voltage acquisition, video function, data output to the computer hard disk automatic.
11. Function: load setting, displacement setting test, extrusion force and displacement maintenance test in multi-stage.
12. Shielded screen protection, safe and convenient.
13. Working space adopt closed structure.
14. Using PLC automatic control, the human-computer interface could pre-setting various working modes, operation easy and convenient.
15. The operation is safe and stable, reilable, and the operation is convenient.
16.Computer remote control, pressure, stroke, total voltage or monomer voltage can be individually or combined as control variables; and any conditions reach the setting value the test will be stopped.
17.The data acquisition of voltage, temperature, pressure, speed and other parameters are synchronously output and recorded the stored data, and derived the EXCEL format with the curve chart.
The frequency of data acquisition can be set randomly, the minimum time unit is 1s .
18. The input of the voltage signal has the function of reverse connection or automatic speed recognition (the abnormity is displayed after the overpass, but it could not damage the data acquisition system).
19.Pollution discharge function: the bottom of the test chamber has a extractable collection tray for collecting the electrolyte or chippings.
20.Explosion-proof device: With the function of exhaust, a lot of waste gas from the test will be discharged out of the door; it has the function of explosion-proof and pressure relief.
21.Smoke exhausting device:The back of the equipment is added two exhaust holes, which can be connected to the laboratory exhaust pipe to discharge the smoke.
22.Fire extinguisher: manual CO2 Fire extinguishing device.
