Battery needle puncture testing machine

Usage: Used for needle puncture testing of lithium primary batteries and other primary batteries, as well as lithium-ion batteries (used in digital electronic products such as mobile phones, laptops, cameras, etc.), nickel hydrogen, nickel cadmium, and lead-acid batteries (used in products such as power tools, toys, electric bicycles, etc.) .

Technical specification requirements:

1 Scope of Application

1.1 Applicable standard

2） The machine has. pressure.time Two control methods,

3） Control method: 1.microcontroller 2 . PLC computer control

Main technical parameters

1 comply withQCT743-2006Lithium ion batteries for electric vehiclesQC/T743-201X(upcoming revised version)GB 8897.4-2008The Primary Battery4Part: Safety Requirements for Lithium BatteriesQB T 2502-2000Standard experimental requirements such as the General Specification for Lithium ion Batteries;

2 Studio size: not less than600×600×600 mmMeasurable battery size:500×500×500 mm；

3 When conducting needle puncture tests on individual batteries and module batteries, the size, shape, steel needle diameter, and length of the needle puncture head should comply with the requirements4.1According to various standards, it should be easy to disassemble and replace.

4 Acupuncture speed:10—50 mm/sAdjustable; Drive mode: electro-hydraulic servo drive.

5 Acupuncture force:10—50kNAdjustable.

6 Stroke (hydraulic cylinder stroke):0—500mmThe experimental platform can be adjusted up and down to obtain different sample placement heights.

7 High temperature resistant tungsten steel needle, with a diameter of Φ2.5-Φ10mm.

8 matching300mmThe thickness of the middle load-bearing plate is designed to facilitate the needle punching test of small-sized batteries;

9 The experimental box is equipped with an intelligent monitoring camera system; There is an electronic door lock system. The experiment can only begin after the door is closed; There are explosion-proof observation windows and explosion-proof lighting fixtures;

10 The chassis is made of high-strength steel, with two layers inside and outside, and the thickness of the inner layer is ≥10mmThere is insulation cotton and buffer film added in the middle; The thickness of the iron gate shall not be less than10mmThe inner material of the working chamber is made of corrosion-resistant insulation material, and all corners of the working chamber are designed with rounded lines, with no seams connecting the corners. The working chamber is equipped with drainage holes and a filter screen for easy cleaning.

11 There is a smoke detection alarm; There is an independent ventilation duct connected to the outside, and the flue is made of non combustible materials for emitting toxic gases; Equipped with a high-power exhaust system, it can quickly release toxic gases from the test chamber; Equipped with smoke filtering system; Equipped with an indoor air purification system to remove pollution caused by smoke and toxic gases leaking into the laboratory.

12 Detect the internal temperature of the test chamber to achieve the purpose of fire detection. If the battery causes a fire during the experiment, the automatic fire extinguishing device can be quickly activated.

13 The test chamber is equipped with a pressure relief valve. In the event of an explosion, the pressure will be quickly released to the outside through the pressure relief valve to ensure that the test chamber and external personnel are not damaged.

14 It can achieve both on-site and remote control methods;

15 Acupuncture control can be controlled by force and displacement, and the force and displacement can be maintained in multiple stages, making it convenient for users to program and control in multiple stages;

16 Acupuncture stopping conditions: pressure cut-off, acupuncture depth cut-off, voltage cut-off can be set to stop the acupuncture test.

17Computer remote control,PLCControl can simultaneously collect voltage, temperature, pressure, and speed; Voltage and temperature collection shall not be less than8Channel; The testing time and testing schedule can be set arbitrarily, and real-time monitoring of needle penetration depth, voltage, temperature parameter values, and curves can be achieved. The LCD digital display is convenient for recording test data and exporting itEXCELFormat saving.

18 Force control accuracy: ±1%Displacement control accuracy: ±1%Speed control accuracy: ±0.1mm/sVoltage control accuracy: measured value±0.5%Temperature measurement accuracy:±1℃, display resolution0.1℃。

19 The frequency of data collection shall not be less than100time/Seconds; Voltage display0—200VTemperature display0—1200℃。

20 The duration of acupuncture can be adjusted.

21 The hardware has an emergency stop function; Input protection: under voltage, over-voltage, over-current, phase loss, overload, over temperature shutdown protection alarm; Output protection: overvoltage, overcurrent, overload.
