Technical Parameters

1. Relevant standard test requirements

1.1 The Battery Pack External Fire Exposure Testing Equipment matches the requirements of UL 2580 clause 42, ECE R100 Annex 8E, etc. The test object is the electrical road vehicle battery packs or systems.

1.2 The test environment temperature is above 0℃, the wind speed is not more than 2.5km/h, and the SOC requirement of the battery pack is above 50%

1.3 In the test, the size of the flat plate containing gasoline exceeds the horizontal size of the test object by 20cm, but not more than 50cm. The height of the pan should not be higher than 8cm above the gasoline surface. The test object should be centered. The distance between the gasoline liquid level and the bottom of the test object was set to 50 cm. Fill the bottom of the pan with water. The schematic diagram of the external fire is shown in the figure:

1.4 The first stage: preheating. Ignite gasoline at least 3m away from the test object, and after 60 seconds of warm-up, place the oil pan under the device under test. If the gasoline flat plate is too large to move, move the test object and stand

1.5 The second stage: direct combustion. Test subjects are directly exposed to flame for 70 seconds

1.6 The third stage: indirect combustion. Put the refractory baffle over the oil pan. Test subjects test in this state for 60 seconds. Or by mutual agreement, continue to be directly exposed to the flame for 60s. The refractory clapboard is made of standard refractory bricks. The specific mesh size is shown in the figure below. It can also be made of refractory materials with reference to this size. 

Fire resistance: (Seger-Kegel) SK 30

A12O3 composition: 30-33%

Porosity (Po): 20-22% volume

Density: 1900-2000kg/m3

Effective hole area: 44.18%

1.7 The fourth stage: Leave the fire source. Remove the gasoline flat plate or the sample and observe for 2 hours or the surface temperature of the sample drops below 45℃.
