Design Standards - Xiaomi SU7 is designed according to the most stringent three safety standards: C-NCAP 2024 version five-star, Euro NCAP 2023 version five-star, and C-IASI 2023 version 3G+ [9][14]. - The vehicle's body structure utilizes a steel-aluminum hybrid design, with high-strength steel and aluminum accounting for over 90% of the materials used, and the maximum strength reaching 2000 MPa [10][14]. Safety Features - The overall torsional rigidity of the vehicle reaches 51,000 N·m/deg, indicating a robust structural design [10][14]. - The battery safety features include a self-developed battery pack factory, 14 layers of physical protection, 17 layers of high-voltage insulation, and a dual large-area active cooling system [14]. - The innovative battery cell inversion technology ensures that in the event of thermal runaway, the ejection direction is away from the passenger compartment, achieving "no open flame, no heat spread" [14]. Testing and Validation - The battery pack has undergone IP6K9K sealing tests and has experienced over 1,000 safety tests, which is 20 times the number required by national standards [14].
