The battery combustion test machine is suitable for the flame resistance test of lithium batteries (or battery packs).

Test instructions:

1. Place the test lithium battery or battery pack on a wire mesh located on a circular hole with a diameter of 102mm (4 inches). The wire mesh is composed of 20 mesh wires per inch, with a wire diameter of 0.017 inches (0.43mm).

2. Place the steel wire mesh approximately 38mm above the flame.

3. Cover the sample with an octagonal aluminum wire mesh. The specifications of the aluminum wire mesh are: the distance between the parallel sides is (610 plusmn; 10) mm, and the height is (305 plusmn; 5) mm. The specification of aluminum wire mesh is aluminum wire diameter 0.25mm, mesh size 16-18

4. Ensure that the test sample is heated on the wire mesh until it explodes or the lithium battery (battery pack) is ignited and burned out.

5. Test results: After the test, the components that make up the battery (excluding dust like products) or the entire battery must not penetrate the aluminum mesh.

According to the standard:

GB 31241-2014 quot;Safety requirements for lithium-ion batteries and battery packs for portable electronic productsquot;

UL 1642 quot;Lithium Battery Standard (Safety)quot;

UL 2054 Safety Standard (Lithium Battery)

Technical parameters:

1. Control method: PLC human-machine touch interface

2. Burner: Bunsen burner, with an inner diameter of 9.5mm and a length of approximately 100mm

3. Flame application time: 0~999.9 seconds plusmn; 0.1 seconds

4. Test circular hole surface diameter: 102mm

5. Experimental mesh screen: A mesh screen with 20 grids woven from stainless steel wire with a diameter of 0.43mm (0.017inch) into a US inch mesh screen

6. Ignition controller: Remote control ignition, automatic control during the test process

7. Remote line control distance: unobstructed, 10 meters

8. Flame screen height: 38mm

9. Test the width of the octagonal mesh cover: the distance between each side is 24 inches (610mm), octagonal, and the eight sides are movable for easy replacement and disassembly

10. Test the height of the octagonal mesh cover: 12 quot;(305mm)

11. Octagonal cover material: aluminum mesh, composed of 0.010 inch (0.25mm) diameter aluminum wire woven into a mesh containing 16-18 grids per inch

12. Smoke exhaust outlet: There is one smoke exhaust outlet installed at the rear of the equipment, with a diameter of 110mm

13. Combustion gas: liquefied petroleum gas or industrial methane (to be provided by the customer)
