1. Definition of battery puncture testing machine
The battery puncture test machine is a test equipment specially used to simulate the safety performance of batteries when punctured by sharp objects. It punctures the battery through a mechanical device to observe whether the battery will catch fire, explode or other dangerous situations, thereby evaluating the safety performance of the battery.
2. Working principle of battery puncture testing machine
The working principle of the battery puncture test machine is relatively simple and mainly includes the following steps:
1.stationary battery: Fix the battery to be tested on the fixture of the testing machine to ensure that the battery will not move during the test.
2.needle movement: The puncture needle is driven by a motor or hydraulic system to puncture the battery at a set speed and force.
3.Data collection: During the puncture process, the device will record the temperature, voltage, current and other parameters of the battery in real time, and monitor whether thermal runaway occurs.
4.Result analysis: Evaluate the safety performance of the battery based on the collected data and observed phenomena.
3. Application scenarios of battery puncture testing machine
Battery puncture testing machines are widely used in the following fields:
1.New energy automobile industry: Used to test the safety of power batteries to ensure that vehicles will not cause accidents due to battery problems in extreme circumstances.
2.Energy storage industry: Used to evaluate the safety performance of energy storage batteries and prevent fires caused by battery thermal runaway.
3.Battery R&D: Help R&D personnel optimize battery design and improve battery safety performance.
4.Quality inspection: As a required inspection item before the battery leaves the factory, it ensures that the battery meets relevant safety standards.
