Lithium ion batteries are widely used in various electronic products and new energy vehicles due to their high energy density. However, their safety issues, especially the risk of fire and explosion caused by thermal runaway, have always been a focus of industry attention. Thermal runaway is a violent chain reaction process with complex and rapidly changing internal mechanisms. Among the tools used to study this phenomenon, the battery needle puncture testing machine plays a key role as a “surgeon“ and is one of the more direct and effective methods in the laboratory to simulate internal short circuits and reveal the mechanism of thermal runaway.

The battery short-circuit test is a crucial step in evaluating the safety performance of batteries, and improper operation can easily lead to risks such as battery fire and explosion. From the perspective of the entire process, the following outlines the key points for standardized operation of battery short-circuit testing machines, in order to help avoid safety hazards and testing errors. ​

The detection data of vacuum cleaner air performance testing equipment (such as anemometer, negative pressure gauge, etc.) directly determines whether the product meets the requirements of national standards (such as GB/T 1019-2021), and regular calibration is the core link to ensure accurate data, which needs to follow standardized procedures for operation. ​

The plastic track impact absorption tester is a key equipment to ensure the safety of sports fields, and its measurement accuracy depends on standardized daily maintenance and timely fault handling. A scientific maintenance process can significantly extend the lifespan of equipment and reduce detection errors. ​

The automation control system of the oxygen rich spark ignition test device is the core to achieve precise testing and safe operation. Through multi module collaboration, it realizes integrated management of parameter regulation, process monitoring, and safety interlocking. Its design needs to balance control accuracy and anti-interference ability to meet the complex combustion test requirements in oxygen rich environments. ​
