UL 2580 PLC PC Control External Fire Test Machine for EV Battery Safety

EV Battery Safety Tester External Fire Test Machine According to UL 2580

External Fire Exposure Test Machine Standard

• UL 2580

Relative Standard test requirements

1. Test Object: Battery pack and system.
2. The test ambient temperature should be above 0 ℃, wind speed is not more than 2.5 km/h, and the SOC requirement of the battery pack is more than 50%.
3. In the test, the size of the Flat plate with gasoline should exceed the horizontal size of the test object by 20 cm, no more than 50 cm. The height of the Flat plate should no more than 8 cm above the gasoline. The test object should be placed in the middle. The distance between the gasoline level and the test object is set to 50 cm. Inject water to the bottom of the Flat-plate before testing. The external burning diagram is shown in the graph.

• Test Phase 1: Preheat.

Ignite the gasoline at least 3m away from the test object, and after 60 seconds of preheating, put the gasoline plate below the test device. If the gasoline flat plate size is too large to move, you can use the way of moving the test object and rack.

• Test Phase 2: Direct burning.

The test object is directly exposed to the flame for 70 seconds.

• Test Phase 3: Indirect burning.

Cover the gasoline plate with refractory baffles. Keep the test object in this condition for 60 seconds. Alternatively, by mutual consent, the test object continues to be exposed directly to the flame for another 60 seconds. The refractory baffles are made of standard refractory bricks. The sieve hole size is shown in the figure below. Refractory can also be made with reference to this size.

• Test Phase 4: Leave the fire source.

Remove the gasoline plate or test object. Then observe for 2h or when the test object exterior temperature drops below 45°C.
