Lithium ion Battery Cell Nail Penetration Test

 

The nail penetration test for lithium-ion battery cells refers to testing the safety and protective performance of lithium-ion battery cells by inserting needles or other sharp objects into the battery cell shell. This type of test is one of the important means to evaluate the resistance and protective performance of battery cells to external forces. The following are the relevant contents of the needle puncture test for lithium-ion battery cells:

 

1. Testing equipment: This test requires the use of professional high-precision needle piercing testing instruments, which have the characteristics of high accuracy, good stability, and strong repeatability. During testing, the appropriate needle diameter should be selected based on the battery cell model, usually 3 mm, 5 mm, etc.

  

2. Test method: Before testing, the battery cell should be charged to the standard voltage and then placed on the test bench. Adjust the corresponding testing parameters, such as the speed, depth, and time of the needle, and then insert the needle into the battery cell shell to test its normal operation, temperature changes, internal pressure, and current changes in the battery.

3. Test results: The results of the battery cell nail penetration test mainly include the degree of shell deformation, internal temperature changes, internal pressure of the battery, current changes, and other information. When evaluating the safety and protective performance of battery cells, analysis and judgment should be based on the test results.

 

4. Attention to safety: When conducting needle puncture tests, relevant operating procedures and safety precautions should be followed, such as wearing protective gloves and protective clothing. After the test is completed, the testing equipment must be cleaned and maintained, and the battery cells must be properly handled and disposed of.

 

In summary, the nail penetration test of lithium-ion battery cells is an important testing method for evaluating the safety and protective performance of lithium batteries. Before conducting the test, it is necessary to select appropriate testing equipment and parameters, and strictly follow the operating procedures and safety precautions to ensure the accuracy and safety of the test.

The System of High Low Temperature Chamber, Temperature Humidity Test Chamber

Image
  Interpretation of environmental simulation tests: There is all kind of environments in nature: high temperature, low temperature, humidity, ultraviolet light, sunlight, rain, etc. Different natural environments affect all kinds of our lives to varying degrees. An environmental simulation test is an activity performed to maintain functional reliability in all environments of expected use, transportation, or storage. It is to expose the product to natural or artificial environmental conditions to undergo its effects, in order to evaluate the performance of the product in the actual use, transportation, and storage of environmental conditions, and to analyze and study the degree of influence of environmental factors and their mechanisms. Introduce our Bell’s high and low temperature test chambers, constant temperature and humidity test chambers, both of which are also environmental chambers for battery safety.       The following introduces our environmental test c...

Something about walk-in high and low temperature chamber

  How does the automation control system of the walk-in high and low temperature chamber work ? 1. Sensor acquisition: Firstly, the system will use a temperature sensor to monitor the temperature inside the test chamber and convert the temperature value into an electrical signal. These sensors can monitor the temperature changes inside the test chamber in real time, ensuring the accuracy of the data.   2. Signal processing: Next, the electrical signal is sent to the controller for processing. The controller calculates the amplitude that needs to be adjusted based on the preset temperature target value and the current temperature value to achieve the set temperature target.   3. Control calculation: The controller will adjust the operating status of the refrigeration unit or heater through PID (Proportional Integral Differential) control algorithm based on the calculation results to achieve accurate temperature control. The PID control algorithm can effective...
