Battery Combustion Test Machine Experimental Description

Author:QINSUN Released in:2023-08 Click:88

The battery combustion test machine is suitable for the flame resistance test of lithium batteries (or battery packs). It is a test equipment independently developed and produced by our company. Full service.

Standards:

GB 31241-2014 \"Safety requirements for lithium-ion batteries and battery packs for portable electronic products\"

UL 1642\" Standard for lithium batteries (Safety

UL 2054 \"Safety Standard (Lithium Batteries)\"

Description of the experiment:

1. Place the lithium battery or the test battery pack in a wire mesh. , the wire mesh is placed over a round hole 102 mm (4 inches) in diameter. The wire mesh was made of 20 mesh per inch wire 0.017\" (0.43mm) diameter.

2. The wire mesh is placed approximately 38 mm above the flame.

3. Cover the sample with aluminum meshoctagonal. The specifications of the aluminum mesh are: the distance between the two sides parallel to each other is (610±10)mm, and the height is (305±5)mm. The specification of aluminum wire mesh is aluminum wire diameter 0.25mm, mesh number 16~18

4. Make sure the test sample is heated on the steel wire mesh until it explodes or on the lithium battery (battery) is ignited and burned.

5. Test results: After the test, the components that make up the battery (except dusty products) or the battery as a whole must not penetrate the aluminum mesh.

Technical parameters:

1. Control method: PLC human-machine touch interface

2. Burner: Bunsen burner, the inner diameter of the nozzle is 9.5mm, and the length is about 100mm

3. The flame application time: 0 ~ 999.9 seconds ± 0.1 seconds

4. Trial circle Hole surface diameter: 102 mm

5. Trial mesh: woven by a stainless steel wire with a diameter of 0.43 mm (0.017 inch) through a mesh screen with 20 meshes per inch

6. Ignition controller: remote control ignition, automatic process control of test

7. Remote controlWire control distance: no barrier, 10 meters

8. Height of flame on the wire mesh: 38 mm

9. Test the width of the octagonal grid: the distance between each pair of faces is 24″ (610 mm), octagonal, and all eight sides are movable for easy replacement and disassembly

10. Test octagonal grid height: 12″ (305mm)

11. octagonal cover material: aluminum mesh, woven from aluminum wire with a diameter of 0.010 inch (0. 25 mm) to contain 16-1Composition of 8 grids

12. Smoke evacuation outlet: There ishas a smoke outlet at the rear of the equipment, 110 mm in diameter

13. Combustion gas: liquefied petroleum gas or industrial methane (supplied by the customer)
