Common operational errors and their consequences when using a battery needle testing machine

Against the backdrop of the booming development of the new energy vehicle industry, the position of lithium-ion batteries as the power core of electric vehicles is increasingly prominent. To ensure that these energy storage devices remain stable and reliable in the face of extreme situations,Battery needle puncture testing machineAs an important detection device, it plays an irreplaceable role.

　　Battery needle puncture testIt is a precise and rigorous test aimed at evaluating the safety performance of batteries in extreme situations. However, improper operation may lead to distorted test results that cannot accurately reflect the true safety level of the battery. Here are several common erroneous operations and their potential adverse consequences:

　　1. Ignore preprocessing conditions

Error operation: Ignoring standardized preprocessing of the battery, such as not storing the battery according to the specified temperature and humidity conditions, or not fully charging the battery to the specified state.

Consequence: This negligence can lead to inconsistent battery states, directly affecting the reliability of test results and rendering comparisons of batteries of the same model meaningless.

　　2. Needle does not meet the standard

Incorrect operation: Using needles that do not meet the specified size, material, or passivation for testing, or not cleaning and disinfecting the needles according to regulations.

Consequences: Inappropriate needles may cause the puncture force, depth, and speed to deviate from the set values, affecting the reproducibility and consistency of the experiment; Pollutants may introduce additional variables that interfere with data interpretation.

　　3. Improper parameter settings

Incorrect operation: The various parameter settings of the battery needle puncture testing machine (such as pressure, speed, puncture position, etc.) were not adjusted according to standard requirements, or the parameters were suddenly changed during the testing process.

Consequence: Inaccurate parameter settings can lead to test conditions deviating from the standard, making the results unable to objectively reflect the performance of the battery under real conditions. In severe cases, it may trigger unnecessary battery failure modes and mislead subsequent product improvement decisions.

　　4. Lack of safety awareness

Incorrect operation: Neglecting safety regulations during the testing process, such as not wearing protective equipment, not activating the fire prevention system, or the presence of other flammable materials in the laboratory.

Consequence: During the battery needle puncture test, it is possible to cause severe reactions in the battery, including thermal runaway, explosion, and fire, endangering the personal safety of the operator and laboratory facilities.

　　5. Ignore data recording

Incorrect operation: Failure to record in detail the readings of every parameter during the experiment, or failure to immediately record any abnormalities discovered.

Consequence: The lack of complete data records means that the experimental conditions cannot be reproduced, making it difficult to analyze and interpret the results, and losing the opportunity to locate and solve problems.

　　6. Neglecting subsequent analysis

Incorrect operation: Only focusing on the completion of the experiment itself, neglecting the data analysis of the test results, and failing to explore the specific reasons for battery failure in depth.

Consequence: Unanalyzed results can only indicate what type of failure occurred in the battery, but cannot guide the improvement of design or production processes, wasting valuable testing resources.

In order to avoid the above errors, users should strictly follow the operation manual to perform each step, regularly participate in professional training, enhance their understanding of the test standards and safety awareness, ensure that each needle puncture test can provide accurate and meaningful information, and contribute to the continuous progress of battery technology and safety standards.
