battery crush & nail penetration tester

Lithium-ion Battery Crushing Test Machine China Manufacturer and Supplier

Lithium-ion Battery Crush & Nail Penetration Test Equipment is used to simulate the mechanical abuse, including the crushing and nail penetration exerted on the lithium-ion cells/batteries, to determine their safety performance when subjected to the same conditions in practical applications.

In particular, the crush test is essential for battery safety testing, and you can almost see it in all mainstream lithium-ion battery safety testing standards.

AMADE TECH lithium-ion battery tester is a 2-in-1 dual-purpose testing equipment thanks to the replaceable test fixtures and attachment inside the chamber. Before the test, it allows you to mount crushing plates or crushing heads in different sizes and shapes to perform the crushing test or mount the corresponding needles and fixtures to perform the nail penetration test. The whole disassembly and assembly process is effortless and convenient.

Our conventional crush & nail penetration test equipment has a common feature: the test space adopts an enclosed box structure. It is because unqualified battery samples may be encountered during testing, which means that an internal short circuit may occur and cause a fire or explosion. This box-type structure can effectively isolate the testing area from the external laboratory environment. In the event of a fire or explosion, it can control and limit the flame, smoke, and shock waves within the box as much as possible, thereby protecting surrounding people or equipment from hurt. Apart from this, we have also equipped the equipment with safety features such as pressure relief vents, explosion-proof chains, smoke vents, and even fire extinguishers if necessary.

For the crushing test of large-volume battery packs, we can also supply unconventional horizontal open-type testing machines to provide greater crushing force and test space.

Control System

We configure each battery crush & nail penetration test equipment with a computer pre-installed with specialized testing software. With the support of PLC, precise control and real-time data display of parameters such as applied pressure, specimen deformation, specimen voltage, and specimen surface temperature can be achieved. You are allowed to preset the desired parameter values based on the standard’s requirements. The machine automatically ends the test when the test conditions reach any of the preset values.

Li-ion Battery Crush & Nail Penetration Tester Features

  • The box is divided into three layers: the material of the outer box is cold-rolled steel plates. The inner box is made of stainless steel, and the intermediate layer plays the role of buffering and heat preservation.

  • The computer control unit is separate from the test box.

  • Support a variety of different machine styles to meet your testing requirements.

  • Equipped with various safety features, such as explosion-proof chains, pressure relief port, smoke detector, web camera, etc.

  • Fitted with a piece of tempered glass at the front of the chamber for easy observation during testing.

  • The inner chamber is equipped with explosion-proof lighting.

  • The servo motor and drive system enhance the control accuracy.

  • Support free selection and collocation of test conditions such as pressure, voltage, deformation, etc., as variables.

  • Thanks to the built-in PLC unit, and the pre-installed professional software, the monitoring and execution of all parameters are controlled by the computer. When the test conditions are reached, it will automatically stop.

  • Test results can be stored and exported for further editing.

Learn More about the Crush Test

With the wide application of lithium-ion batteries, it has become the power source of much industrial equipment and electric vehicles from its initial use as a power source for consumer electronics products. Due to lithium-ion batteries’ special material and chemical characteristics, their safety hazards still exist when subjected to extreme situations. Especially in the event of an electric vehicle crash, the battery pack will inevitably be crushed and deformed in the accident. If these power units fail the crush or needle tests, there may be dangerous consequences.

The crush or nail penetration test for the lithium-ion cell, module and battery pack is an essential safety test item. In order to test the safety of lithium-ion cells and batteries, many international organizations have formulated and promulgated regulations and standards for different applications. The process of the crush and nail penetration tests is described in the test methods.

  • Crushing force: The maximum crushing force exerted on the cell is usually 13 kN, but the crushing force applied to the electric vehicle battery is required not to exceed 1000 times that of the tested object. Usually, the upper limit of crushing force is 200 kN, 500 kN even 1000 kN.
  • Drive mode: The drive mode of the battery crushing test equipment depends on the upper limits of the required crushing force. Generally, we choose servo drive for conventional models or electro-hydraulic servo drive for models needing large crushing forces.
  • Crushing head: We configure different crushing heads according to the type of test samples(cells, modules or battery packs) and the test standards to be followed.
  • Data acquisition: The crushing test is usually controlled by three variables simultaneously: the sample’s voltage, the sample’s deformation, and the maximum pressing force. The test can be stopped if any one of these conditions is met. After the test, it is sometimes required to observe the sample for a period of time or until the surface temperature of the sample drops to a specified value. Therefore, acquiring voltage, sample deformation, pressing force, and sample surface temperature is essential.
