Core Points - The recent revision of the "Technical Conditions for Motor Vehicle Operation Safety" represents a comprehensive upgrade of China's motor vehicle safety management system, addressing new issues in road traffic safety and proactively planning for the development of new energy vehicles and intelligent driving technologies [2] Group 1: Safety Requirements - The revised draft proposes stricter safety technical requirements, including vehicle acceleration performance, safety of new energy vehicles, regulation of auxiliary driving systems, and enhancement of safety performance for large and medium-sized passenger and freight vehicles [1] - Passenger cars must default to a 0-100 km/h acceleration time of no less than 5 seconds after each start, aiming to limit safety risks associated with excessive acceleration performance [1] - Pure electric and plug-in hybrid passenger vehicles are required to have a "pedal misoperation acceleration suppression function" to automatically detect and suppress power output during stationary or low-speed crawling conditions, along with sound and light signals to alert the driver [1] Group 2: Battery Safety Standards - In response to the frequent battery fire incidents in new energy vehicles, the new standards impose specific safety requirements for power batteries, such as automatic disconnection of the power circuit during collisions or airbag deployment [1] - Vehicles must have abnormal monitoring and thermal event warning functions for battery cells, with sound and light signals to alert occupants [1] - Power batteries must include directional pressure relief and pressure balance devices to ensure passenger cabin safety during thermal runaway, and for electric buses longer than 6 meters, the battery compartment must not catch fire or explode within 5 minutes after an alarm [1]
