With the rapid development of battery technology, especially the widespread application of lithium-ion batteries in fields such as electric vehicles and portable electronic products, ensuring the safety of batteries has become a focus of attention in the industry. As an important tool for evaluating battery safety, the design and operation of the battery combustion projectile testing machine must fully consider potential safety hazards to prevent accidents during the testing process that may endanger personnel and property safety.

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. In order to ensure that these energy storage devices remain stable and reliable in the face of extreme situations, the battery needle puncture testing machine plays an irreplaceable role as an important detection device.

Purpose: According to the technical specifications of BS EN IEC 60879:2019, GB/T13380-2018, GB 12021.9-2021 “Energy Efficiency Limits and Grades for Electric Fans“: 1 Scope of application (applicable standards) The requirements for this air volume testing device are based on the convenience of walking, and because the testing methods are basically the same, it can meet the air volume testing requirements of table fans, wall fans, floor fans, and column fans Four anemometers are used to collect wind speed (two anemometers are added in the vertical direction on top of the original two horizontal anemometers on the test plane) to represent the average wind speed on the same ring.
