2.Equipment Overview

2.1 Equipment Overview

This machine is specifically designed to test the damage caused by product packaging falling and evaluate the impact resistance during transportation and handling;

The test sample automatically rises to the predetermined height and then falls freely in the predetermined state, colliding with the impact table;

2.2 Main Features

(1)This machine can perform free fall tests on the surface, corners, and edges of objects such as battery packs and battery systems;

(2)Equipped with a digital height display instrument and using an encoder for height tracking, it can accurately determine the drop height of the product;

(3)The drop height error shall not exceed 2% or 10mm;

(4)This machine adopts a single arm double column structure, with electric reset, electric drop and electric lifting devices, making it easy to use;

(5)The machine is equipped with a buffering device, which can improve the service life, stability, and safety of the machine;

(6)Single arm setup allows for easy placement of products, with an error in the angle between the impact surface and the bottom plate plane when dropped≤5º；

(7)base plate thickness≥10mm， It can withstand a load of 2KG ± 100g at a height of 1.5 meters, without tilting or shaking during equipment testing, and achieve free drop of packaging.

3. Compliant with standards

GB31241-2022 Safety requirements for lithium-ion batteries and battery packs for portable electronic products;

4. Test rules

Lift the test sample and fix it on the drop arm, support it in the predetermined state, and raise it to the desired drop height position. Its height is consistent with the predetermined height The difference shall not exceed the predetermined height± 2%. The drop height refers to the distance between the lowest point of the test sample and the impact table when released. Release the test sample in the following predetermined state:

A.When the surface is dropped, the maximum angle between the dropped surface of the test sample and the horizontal plane should not exceed 2º；

B.When the edge falls, the maximum angle between the falling edge and the horizontal plane should not exceed 2 º, the error of the angle between the specified surface on the test sample and the impact table surface shall not exceed ± 5 º or 10% of the angle (whichever is larger), so that the gravity line of the test sample passes through the dropped edge;

C.When the angle drops, the angle error between the specified surface on the test sample and the impact table surface shall not exceed± 5 º or 10% of this angle (whichever is greater), so that the gravity line of the test sample passes through the angle at which it is dropped;

D.Regardless of the state and shape of the test sample, the gravity line of the test sample should pass through the dropped surface, line, or point;

E.The difference between the actual impact velocity and the impact velocity during free fall shall not exceed that during free fall±1%；

F. After the experiment, inspect the packaging and contents for damage according to relevant standards or regulations, and analyze the test results
