Lithium-ion Battery Impact Tester Manufacturer

Battery Impact Testing Machine China Manufacturer

Lithium-ion battery impact tester is intended to simulate the impact of a cell or battery block by a heavy hammer in a free fall from a specified height. The safety performance of the cell or batteries can be judged by observing whether the sample catches fire and explodes.

Unintentional impacts of batteries during daily use or transport are a foreseeable situation. An unqualified battery may cause an internal short circuit after being hit and cause the battery to catch fire or explode.

In the international testing regulations for the transportation of dangerous goods, it is stipulated that cylindrical batteries such as 18650 cells should be subjected to a free-fall impact test with a weight of 9.1 kg. The UL lithium battery safety standard is also required to perform an impact test. Secondary lithium cells and batteries in industrial applications also require impact testing.

The battery Impact testing machine is one of the important members of lithium-ion battery safety testing devices.

TEST PRINCIPLE

A weight of specified mass hits the sample in free fall from a specified height. The weight must not be shaken as it falls. After the impact is completed, the sample is qualified if it does not catch fire and does not explode.

Test Methods

The sample cell is placed on a flat surface. A stainless steel rod with a diameter of 15.8 mm was placed criss-cross at the geometric center of the sample.
- The cylindrical battery is required to make its longitudinal axis parallel to the surface of the heavy massduring the impact test, and the metal rod is perpendicular to the longitudinal axis of the battery.
- Rectangular and pouch batteriesare only subjected to the impact test on the wide side.
- Coin or Button cells are impactedwith a metal rod across the center of the cell surface.
Set the drop height, and elevate the heavy hammer to an intended value by means of the electric lifting device.
Press the start button to make the weight of 9.1 kg impact the specimen in a free-falling manner. (Each sample cell only has to withstand one impact, and a different sample is used for each test.)

Features of Battery Impact Testers from AMADE TECH

The internal box is made of 304 stainless steel and pasted with Teflon tapes for insulation, which is fireproof and easy to clean after testing. And the external box is made of cold-rolled sheets.
The hammer and lifting apparatus are guided by 2 vertical rods to prevent tilt and waggling during dropping.
The double-column design and equipped with a safety hook can effectively prevent the heavy hammer hanging at a high position from falling automatically once the brake motor is powered off, thus resulting in potential safety hazards.
Configured with a touch screen with an intuitive operation interface.
The impact height is adjustable, ranging from 0 to 1000 mm.
Supports one button to lift the hammer electrically.
The door is fitted with an explosion-proof glass as the observation window.
An illuminating lamp is configured inside the chamber to facilitate the observation.
It can automatically detect the opening and closing status of the door, and the test cannot be started when the door is open.
An exhaust outlet and pressure relief port are available in the equipment to vent and relieve pressure once there is a fire or explosion.
