Cell pressure loading test machine: the guardian of new energy power battery pack safety

With the increasing popularity of new energy electric vehicles and portable electronic devices, the safety and reliability of batteries have become the focus of attention.The quality of the battery cell is directly related to the performance and safety of the battery. As the core component of the battery, the quality of the core is directly related to the performance and safety of the battery.Cell pressure loading testerIt is one such device that is specifically designed to test the safety of the battery cells.Here, let's unveil the mystery of this machine.

1. Cell pressure loading testerrole of

Cell pressure loading testerIt is mainly used to test the airtightness, constant pressure loading tensile burst strength and variable load compressive strength of the electric core. It evaluates the structural stability and safety of the battery cell by simulating various pressure situations that the battery cell may encounter during actual use.

Practical application examples of JCGK pressure loading tester

Simply put, it is a kind of specialized equipment for safety performance testing of power battery cells. ThroughBy simulating the extreme conditions that the battery cells may be subjected to in various environments, we test their airtightness, pressure resistance, and other indicators, so as to make a comprehensive assessment of the safety of the battery in use.

2. Cell airtightness testing

Airtightness is crucial for the electric core, because once the core leaks, internal short-circuiting, electrolyte evaporation and other hidden dangers of use may occur, which may lead to cause safety accidents.Cell pressure loading testerUtilizing high-pressure gas storage tanks and test water tanks to detect whether the electric core will leak, expand and other abnormalities under a certain pressureThis ensures the sealing performance of the cell.

3. Constant pressure loading pull-out test

Sometimes the battery pack is heated by foreign objects or short-circuited and the internal pressure increases dramatically. In the constant pressure loading pull burst test, theThe tester will continue to apply high pressure to the battery cell to simulate this extreme environment until the battery cell "pulls out" and ruptures.(internal gas escape), to detect its maximum degree of pressure resistance. This test evaluates the structural integrity of the cell under sustained pressure and provides an important reference for battery design and manufacturing.

4. Variable load compressive strength test

In addition to the constant-pressure burst test, the cell may also be subjected to cyclic loading and unloading pressure during actual use.The variable load compressive strength test simulates the cyclic pressure variations that a battery cell may encounter under different conditions of use.The test machine can apply repeated changes of pressure to the battery cell in different pressure segments to test its pressure resistance performance in this "drop" environment. Through this test, we can understand the pressure-resistant performance of the battery cells in actual use, so as to optimize the structural design of the battery.

5. Principles of operation

Cell pressure loading testerThe working principle is not complicated.It is mainly composed of control system, loading device and test box body.The control system is responsible for setting the test parameters and monitoring the test process, the loading device is used to apply pressure to the cell, and the test chamber is used to hold the cell under test.

6. Scope of application

Cell pressure loading testerThe scope of application is very wide, itServing not only the battery manufacturing industry, but also testing any battery product where sealing and structural integrity need to be ensured.. For example:

Battery Manufacturing:It is used to test the airtightness and pressure strength of various types of battery cells such as lithium batteries, nickel-metal hydride batteries, lead-acid batteries and so on.
