Seres Granted Patent for Battery Pack Detachment in Collisions

[Technological Innovation] Seres has been granted a patent enabling rapid detachment of the battery pack from the vehicle body during a collision.

Key Development: Authorized on May 8, 2026, aimed at enhancing electric vehicle crash safety

The patent, filed by Chongqing Seres New Energy Vehicle Design Institute Co., Ltd., utilizes front and rear support components linked with an electric actuator. Upon receiving a collision signal, the system quickly unlocks the battery pack’s connection mechanism, allowing it to separate from the vehicle chassis—thereby mitigating fire and electrical leakage risks at the source.

Industry Impact: Technically feasible but controversial; likely serves as strategic reserve

Industry insiders note that while this design can isolate thermally runaway batteries and prevent whole-vehicle combustion, the detached battery may pose new hazards to following vehicles. It is speculated that the technology is currently positioned more as a strategic technical reserve rather than for immediate mass production.
