Principle details of equipment:
Test objective:This tester is used to simulate all kinds of power lithium battery in the course of being squeezed.Itpresents different possible situations when the battery is under strong external pressure.When the battery explode or burn during the test,the equipment shall guarantee the personal safety and does not harm the test environment absolutely . In the squeezing test,the battery shall not explode or burn.
Test method
The single cell battery is tested according to the following conditions:
Squeezing direction: pressure should be perpendicular to the battery plate (Refer to figure 1 below)
Squeezing plate form: the half cylinder’s length is 650mm,diameter of 75mm, its size is larger than
the battery Squeezing rate: (5±1)mm/s
Squeezing level:When the voltage reaches 0V or deformation reaches 30% or the extrusion
pressure reaches 30kN, stop squeezing.Observe for 1 hour.
The battery module is tested under the following conditions:
Squeezing plate form:the half cylinder’s length has a diameter of 75mm, its length is longer than
the size of battery,but no more than 1m.
Squeezing direction:it is the same as the most likely direction to be squeezed of the battery module in the vehicle layout. Pressure should be perpendicular to the battery plate or monomer arrangement.
Squeezing rate: (5±1)mm/s
Squeezing level:deformation of battery module reaches 30% or the pressure reaches 1000 times the weight of the battery module and larger values in the following sheet.
Keep it for 10min,observe for 1 hour.
Main feature and function
Equipment safety explosion-proof function,
convenient and environmental protection performance
The equipment should be tested in a separate compartment, surrounded by a solid wall .Compartment door is explosion-proof .There should be 2-3 meters of space around the compartment.For test safety,controller and testing section should be separated.
Tester type:four column vertical structure,maximum extrusion force 30kN
Remote control the main part of the equipment and console extension.Operators stay away from the
test area, guarantee the safety of test personnel.
Inner box, middle layer, outer box are three parts of testing machine:
Inner box material: stainless steel plate (SUS#304 thickness: 3.0mm), stainless steel welded, and all affixed withhigh temperature resistant and flame retardant tape. Not only protect the inner box , it is easy to clean after the test, easy to replace tape.
Outer box material: cold-rolled plate stoving varnish (3.0mm thick), the middle layer has buffer insulation effect, when tank pressure is too large, it can effectively alleviate the pressure impact on outer box.
Meanwhile, inside the box,when the burning tempertureof the test sample is too high,it can effectively interrupt the transmission of temperature, protect the safety of the test personnel.
The rear part of the box is equipped with an explosion-proof door, with explosion-proof door lock. When the inner pressure intensity is too large (about 30kgf), explosion-proof door will open, which is helpful to pressure relief and explosion venting.Explosion-proof door is easy to open and close, easy to operate, good sealing and connection.There should be no sundries within two meters of open space around the explosion-proof door , ;
Front door:single door on left.The front door is equipped with a safety power-off induction switch. When the door is opened, the control part of power equipment can not be started, unable to carry out follow-up operation. Only when the door is closed, the tester can start the control program for subsequent operations, play a protective role in a true sense.
Air smoke exhaust and outfire system
The rear part of the box is equipped with an exhaust fan,has a diameter of 300mm, and an exhaust duct which can connect to external exhaust fan.While the air inlet at the left side of the box can be opened at the end of the test t. Flue gas can be discharged quickly. In the test,exhaust fan should be opened at first.
Smoke alarm and outfire system design: As for battery explosion may occur, first smoke alarms should be installed in the test area.When the test sample lets out smoke, smoke alarm can automatically detect it, the fan would start automatically (you can also start it at the begining). Remind testers manually open the external exhaust fan, smoke would be discharged through the exhaust duct .
Equipped with a fire extinguisher: if the battery is on fire, the fire extinguisher can be operated on the integrated control panel
Lighting design:The top of the test box is equipped with a three-proofings lamp, dustproof,explosion-proof ,fire-proof,explosion proof lamp housing can be replaced easily.
The power battery extrusion test machine has the "emergency stop" button, which is convenient for the emergency treatment in the critical situation, and the emergency stop button is used to stop all the actions of the squeezing testing machine under the critical condition to prevent the occurrence of harm
Equipment strength support section:the bottom of the device is equipped with a fixed universal roller and an adjustable supporting foot for fixed position
