Professional analysis and application of battery pack drop tester (zero drop)
Publish Time: 2024-08-22
With the rapid development of electric vehicles, portable electronic devices and energy storage systems, the safety and reliability of battery packs as their core components have become the focus of industry attention. In order to ensure the safety performance of battery packs and modules under extreme conditions such as transportation, use and accidental falls, battery pack drop testers (especially zero drop function) came into being. This article will discuss in detail the working principle, technical characteristics, application scenarios and importance of this key test equipment.
Working principle
The battery pack drop tester realizes the safe drop test of battery packs and modules through a highly integrated control system. Its core workflow includes the following steps:
Sample installation and positioning: First, place the battery pack or module to be tested safely on the support arm of the tester. As a working surface, the support arm not only firmly supports the sample, but also connects to the control system through a precise mechanical structure.
Height setting: Set the drop height through the control panel according to the test standard or actual needs. The height can start from zero or be accurate to the millimeter level to meet the needs of different test scenarios.
Lifting and release: After starting the test, the lifting device smoothly lifts the support arm and the sample to the preset height. When the specified height is reached, the control system triggers the release mechanism, and the support arm instantly detaches from the sample with an acceleration greater than 1g, ensuring that the sample falls freely with almost no external interference.
Drop and collision: The sample falls freely to the bottom plate plane (impact surface) to complete the drop process. The bottom plate is usually made of high-strength, impact-resistant materials to simulate the collision situation in the real environment.
Data recording and evaluation: During the test, the sensor records key parameters such as impact acceleration, displacement, and velocity in real time, and processes them through data analysis software to evaluate the impact resistance and potential safety risks of the battery pack.
Technical features
Double-column guidance: The double-column structure is adopted to ensure that the lifting process is smooth and without shaking, and improve the accuracy and repeatability of the test.
Electric buffering: Before the sample contacts the bottom plate, the electric buffering device slows down the impact, protects the sample from damage caused by excessive impact force, and simulates the buffering effect in the real environment.
Height adjustment and automatic control: The drop height can be flexibly set according to needs, and automatic control can be realized to improve test efficiency and accuracy.
High-precision sensor: Integrate high-precision sensors to capture and record various parameters during the fall process in real time, providing a reliable basis for data analysis.
Application scenarios
Battery pack drop testers are widely used in the following fields:
Electric vehicle manufacturers: Perform strict drop tests on vehicle-mounted battery packs to ensure their safety performance under extreme conditions such as traffic accidents.
Portable electronic device manufacturers: Perform drop tests on battery modules of mobile phones, tablets and other devices to evaluate their anti-fall capabilities.
Energy storage system suppliers: Perform drop tests on large energy storage battery packs to verify their stability during transportation and installation.
Scientific research institutions and universities: Used for basic research on battery safety performance and new product development.
Importance
Battery pack drop testers play an irreplaceable role in ensuring battery safety and improving product quality. By simulating drop scenarios in real environments, potential safety hazards can be discovered and resolved in a timely manner, providing strong support for product design optimization. At the same time, it is also one of the important testing methods that meet international safety standards and meet market access requirements.
As an important equipment in the field of battery safety testing, the battery pack drop tester (zero drop) has an important role in ensuring battery safety and improving product quality due to its working principle, technical characteristics and application scenarios. With the continuous development of electric vehicles and energy storage technology, the application prospects of this equipment will be broader, providing solid technical support for the sustainable and healthy development of the industry.
