What is a battery acupuncture extrusion testing machine?
With the rapid development of new energy vehicles and energy storage industries, battery safety has become the focus of public attention. Recently, one of the hot topics on the Internet is the battery acupuncture extrusion testing machine. This equipment has attracted much attention because it can simulate the safety performance of batteries under extreme conditions. This article will introduce the definition, principle, application and industry data of this equipment in detail to help readers fully understand its importance.
1. Definition of battery acupuncture extrusion testing machine
The battery acupuncture and extrusion testing machine is a device specially used to test the safety performance of lithium-ion batteries under conditions of mechanical abuse (such as acupuncture and extrusion). By simulating internal short circuit or external stress scenarios of the battery, we can evaluate whether it will cause dangerous situations such as fire and explosion, and provide data support for battery design improvement.
2. Working principle and testing standards
The testing machine tests battery safety in two main ways:
| Test type | Method description | International Standard Reference |
|---|---|---|
| Needle prick test | Penetrate the battery with a steel needle to simulate an internal short circuit | GB 38031-2020, UN38.3 |
| squeeze test | Apply pressure until the battery deforms to simulate external impact | IEC 62660-2 |
3. Industry applications and hot events
Data from the entire network in the past 10 days shows that topics related to battery safety testing have soared in popularity, mainly due to the following events:
| Date | hot events | Social media discussion volume |
|---|---|---|
| 2023-11-05 | A car company released a video of acupuncture testing and the battery did not catch fire | 125,000 times |
| 2023-11-08 | The country plans to revise the mandatory testing standards for power batteries | 87,000 times |
4. Comparison of technical parameters
The key performance indicators of mainstream testing machine manufacturers are as follows:
| Brand | maximum pressure | Needle punching speed | temperature monitoring |
|---|---|---|---|
| Company A | 200kN | 10mm/s | support |
| Company B | 150kN | 25mm/s | Infrared thermal imaging |
5. Future development trends
According to industry analysis, the global battery testing equipment market size in 2024 is expected to reach$4.5 billion, among which acupuncture and extrusion testing machines will account for more than 30%. The following are key drivers:
1. Countries strengthen battery safety regulations
2. Increased demand for testing of new technologies such as solid-state batteries
3. It has become a trend for car companies to build their own battery laboratories
Summary
As the core equipment to ensure battery safety, the battery acupuncture extrusion testing machine’s technological development is directly related to the reliability of the new energy automobile industry. As testing standards become increasingly stringent, this equipment will develop towards higher-precision, multi-scenario simulation, providing important support for the global energy transformation.
