In the field of new energy batteries, it is crucial to guarantee the safety and reliability of batteries. AndBurst Pressure Tester(also called pressure burst tester, burst tester) as a key testing equipment, can help us accurately assess the burst pressure of the battery. In this article, we will introduce in-depthBurst pressure tester use, test principle and pressure unit conversion relationshipIt helps you to better understand and apply the pressure burst tester.
First, the use of burst pressure tester
1. Preparation
- Ensure that the Burst Pressure Tester has been properly connected to the power and air sources and is installed and calibrated according to the instructions.
- According to the type and specification of the battery product, choose the appropriate tooling fixture to fix it in the test chamber.
- Set the desired maximum burst pressure value, test time and pressure loading rate and other parameters.
2. Pressurized test
- Place the battery sample to be tested securely in the test chamber of the tester, ensuring a tight seal.
- Start the instrument and gradually increase the pressure in the sealing chamber by slowly pressurizing it.
- Closely monitor the instrument test interface and battery product status, once there is leakage, cracking or rupture, bursting instrument will immediately stop pressurization, and record the highest pressure value at this time, that is, the actual bursting pressure of the battery product.
3. Security
- Due to the risk of battery explosion during testing, operators are required to wear protective equipment such as protective eyewear and gloves.
- The burst tester should be equipped with an explosion-proof cover or protective chamber to avoid personnel injury due to uncontrolled testing.
- The test site should be well ventilated to prevent the accumulation of harmful gases.
4. Analysis of results

It should be noted that, due to the blasting test has a certain degree of danger, the operator must be professionally trained, familiar with the safety regulations, and strictly comply with the protective measures to ensure that the test process is safe and controlled.
Second, the burst pressure tester test principle
The Burst Pressure Tester observes and records the bursting of batteries under different pressures by applying different pressures to the batteries. It performs the test based on the following principles:
- Data logging and analysis:The Burst Pressure Tester is capable of recording the bursting condition of the battery under different pressures and generating corresponding data and graphs for subsequent analysis and evaluation.
- Pressure sensors:The Burst Pressure Tester has a built-in high-precision pressure sensor for accurately measuring the change in pressure of the battery during testing.
- Control system:The tester's control system is capable of controlling the pressure applied to the battery and monitoring the battery's condition.
For example, new energy rupture disc bursting test is an application of pressure-resistant bursting test. Soft pack battery cells are an important part of power batteries. Soft pack battery cells play a key role in the performance and efficiency of power batteries by enhancing energy density, increasing design flexibility and improving thermal management.The rupture disc bursting test for flexible pack batteries is designed to assess the ability of the battery's aluminum-plastic film to withstand damage under the impact of an explosion, and to reduce the risk of an explosion by releasing the pressure through structural rupture in the event of a failure to improve the battery's safety performance.
III. Pressure unit conversion relationship
When using a burst pressure tester, we often encounter different pressure units. Below are some common pressure units and their conversion relationships:
Commonly used units:
Common units of pressure include pascals (Pa), kilopascals (kPa), megapascals (MPa), bars (bar), and kilograms.
Conversion relationships:
1 kilopascal (kPa) = 1000 pascals (Pa) = 0.001 megapascal (MPa) = 0.01 bar = 0.01 kilograms.
JCGK can provide pressure loading test equipment for gases from a few kPa to 3MPa, and the test range can be customized from high pressure to 5MPa.
Understanding and mastering the conversion relationship between these units will help us to better understand and apply the test results of the burst pressure tester and make accurate judgment and evaluation.
IV. Summary
Burst pressure tester plays a key role in the field of new energy battery, which improves the strong support for the safe design of battery.In the continuous development and innovation of new energy battery technology, JCGK's series of new energy testing equipment will continue to play an important role in ensuring the safety of battery operation and application.
