Purpose
To verify the resistance of the REESS against exposure to fire.
To leave the driver and passengers with enough time to evacuate.

KATRI Outdoor Test
Review
Phase A : Pre-heating, 60sec
Only ‘Direct exposure’
Mock-up simulates real DUT size
(L x W x H, 920 x 605 x 206 mm)
Pan exceed the horizontal
projection of the every DUT side
by 25cm
(Draft : 20 ~ 50cm)
Under the DUT(Center) Temp. :
about 700 ℃
Even if initial wind speed is
lower than Draft limitation,
heat generated by flame causes
turbulence
∵ speed of evaporation, difference of
thermal distribution
☞ REESS are getting bigger
☞ Actually impossible to test on
outside
Phase B : Direct exposure, 70 sec
Phase C : Indirect exposure, 60 sec
An explosion proof test facility
A large ventilation, emission and
waste water disposal facility
☞ An enormous expense
Phase D : End of test, 3hr
Wind speed : 2.5 km/hr (= 0.69 m/sec)
Wind speed : about 0.5 m/sec
Fuel quantity : 25 lit./m2

Burning Temp. : 890 ~ 900 ℃
- LPG + Air, PDA Control
- Top of burner is open
- REESS are getting bigger
☞ Hard to control of burning

Attachment
Draft amendment of KMVSS test procedures
KMVSS Article 18-3.
KMVSS Test Procedure Annex Traction Battery Safety Test
FIRE RESISTANCE TEST
1) TEST PURPOSE
The purpose of this test is to confirm the safety of traction battery to secure an evacuation time for driver and passengers when vehicle is on fire.
2) TEST PROCEDURE
a. The REESS shall be placed on the test equipment. The REESS shall be horizontal.
b. The number of temperature sensors shall be at least 5. The sensor locations shall be representative locations which cover the whole area of REESS. The sensor shall be placed 25 ± 10 mm downward from the bottom of REESS.
c. Whole bottom area of REESS shall be uniformly heated by flames.
d. Temperature shall reach 800 ℃ within 30 sec from ignition. Flames with temperature of 800 ℃ shall be maintained for 2 minutes, after that fuel supply shall be stopped. After 2 hours from the stop of fuel supply, the test shall be terminated. The temperature of flames shall not exceed 1100 ℃.
e. Check the explosion of REESS during the test.
