EV fire in a tunnel! Recently, we challenged our Reliable Automatic Sprinkler Co., Inc. Model TNL280 Tunnel Nozzle against an EV fire in a tunnel fire test series at Applus+ Laboratories in Asturias, Spain. To ignite the first EV we used a customer pan burner positioned under the battery pack. Vehicles were positioned 1 m (3 ft)apart. It took more than 45 min to see the first signs of #thermalrunaway - jet flames from beneath the vehicle. Then we waited for the temperature at the ceiling to reach 68 C (155 F) before starting a 3 minute countdown to deluge system activation. The #fire grew significantly during that 3 minute period, spreading to the adjacent and downstream target vehicles. Once the deluge system was turned on, it effectively controlled and suppressed the fire as can be seen in the video. This was the last of a series of tests - we look forward to sharing the results and the report with you in the near future. Special thanks to the entire team Applus+ Laboratories and Reliable Automatic Sprinkler Co., Inc.’s Product Development Engineering and Product Technology team for the hard work that went into this test series. #sprinklers #fire #firefighting #future #transportation #technology #sustainability #TunnelFireSafety #FireProtection #Infrastructure #Innovation
