On September 23, a video depicting a "battery ejection test" on a new energy vehicle ignited a flurry of online debate. The video's depiction of the battery being abruptly ejected from the vehicle's undercarriage raised widespread safety concerns among the public. In reaction to this, a representative from the China Automotive Crash Technology Research Center offered a comprehensive explanation today. This technology is engineered to, in the event of a severe collision or battery thermal runaway, utilize sensors to monitor the situation and promptly eject the battery pack from the vehicle within 1 second, thereby averting potential in-vehicle fires or explosions. Nevertheless, this design has also stirred up controversy: Once ejected at high velocity, the battery pack, which can weigh several hundred kilograms, poses a significant risk of causing severe damage to nearby pedestrians, vehicles, or structures, particularly in urban or highway settings. Furthermore, the deployment of this technology encounters challenges such as sensor inaccuracies, the delineation of legal responsibility, and the absence of industry-wide standards. Although the developers intend to enhance environmental recognition capabilities through the integration of lidar and cameras, the technology is presently still considered a high-risk approach. In contrast, strategies like enhancing the inherent safety of the battery and refining the battery management system have garnered broader acceptance within the industry.
