According to reports, the system can detect thermal runaway (when one battery cell ignites and the fire spreads rapidly), and it ejects the entire battery pack out of the vehicle. In its current iteration, the battery pack is blasted 10 feet (3 meters) to 20 feet (6 meters) away from the car in under a second.
According to the Australian site CarExpert, the Chinese Vehicle Collision Repair Technical and Research Center and Joyson Electronics created the EV battery ejection technology. The above Facebook post shows it in action, and there''s also a video that''s appearing all over Chinese social media if the embed above doesn''t work.
