Punture machine specification:

Drive mode: hydraulic system drive;

Pressure control: solenoid proportional valve control;

Equipment type: four column horizontal structure

Maximum penetration: 100kN (10 tons)

Maximum test space: 500 x 500 x 500mm (L * W * H), can be tested for a variety of the

                    test space smaller than the size of power cell;

Puncture maximum stroke: 500mm (excluding length)

Puncture speed: (25 + 5) mm/s;

Data sampling frequency: 100 times / sec;

Puncture test time: 0 ~ 9999s can be arbitrarily set

Equipment running direction: from left to right to pierce (horizontal structure, based on the

                                                 thickness direction from the puncture)

Single cell: pierce a battery pack from the direction perpendicular to the center of the battery plate

          (the needle stuck in the battery), observe for 1 hours;

Dimensions:about 2000*1500* 2000mm (L*W*H) (excluding hydraulic oil source

                                           and control box volume);

Equipment structure and features

Equipment safety explosion-proof function, convenient performance and

environmental protection performance

 

  Test should be placed in a separate test compartment, surrounded by a solid wall. Compartment door should be explosion-proof door.There should be should be 2-3 meters of space around the compartment.Controller and testing section should be separated in order to achieve the purpose of safety test.

  Tester type: three beams four columns four nuts horizontal mechanism, advantages of this structure: three beams were high 45# cast steel, with sufficient strength and stiffness; enhance the wear resistance of column surface by chromate treatment, spacious work space, compact structure, flexible action, high speed, low energy consumption, low noise.

Maximum penetration force: 100kN.

Fastest speed: 40mm/s (10 – 40mm/s adjustable)

  Front door: single door,open on the left, front box door equipped with safety power-off induction switch, when the door is opened, the control part of equipment cut off power and can not be started, unable to carry out follow-up operation, only when the box door is closed, it can start the control program for subsequent operations, play a protective role in the true sense.

  Observation window: the window size is 400*400mm, double toughened glass, affix explosion-proof membrane to the toughened glass inside and outside, 10mm thick, square anti projection net can be installed between the double glass, during the protection, the test case can be observed within at the same time .

Puncture fixture: configure a set of puncture fixture according to the requirements of the

               GB/T 31485-2015

Equipment power support part: the device is equipped with a fixed universal roller at the bottom

                            of the device and an adjustable support foot for a fixed position;

 

Hydraulic pressure system

Oil stroke：500mm

Puncture speed:(25±1)mm/s ,operating speed can be adjusted by proportional valve

Maximum puncture force: 100kN (i.e. 10T)

Fuel tank material: stainless steel plate, can effectively prevent the corrosion of long-term use,

                 strong heat dissipation

 

Security protection system:

 

Emergency stop function on the control panel of the equipment ; the whole process of the equipment

        to limit the conditions of protection;

Input protection: under voltage, over voltage, over current, lack of phase, overload shutdown protection;

Output protection: over voltage, over current, over load;

Abnormal protection function and earth leakage protection of the whole machine

The control system is separated from the test box, keep the operator away from the test area,

remote control is available, the cable distance is 10 meters, can maximize the safety protection

of the test personnel

The above design is to ensure the safe operation, stable, reliable control of the machine, while the professional measurement and control system makes it easier for operation

 

A brief introduction to the method of power battery punture test

 Pierce a battery pack from the direction perpendicular to the center of the battery plate,with high temperature resistant steel needle which has a diameter of 3mm ~ 8mm( the cone angle of the needle tip is 45 degrees ~60 degrees.The needle surface is smooth, no rust or oxidationn layer or oil contamination. Observe for an hour.

 

Introduction to the main interface of puncture testing software

4 regions (curve area, real-time acquisition of data area, control panel area and test data area)

at a glance; this system summarize force, deformation (displacement data), voltage in a test

interface display;

Data area can be hidden;

Test settings, curve selection and report print storage;

Test settings include: sample information, control plans, test completion criteria and other

                   common information;

Mobile speed can be set quickly on the test board (for speed requirements of the test);
