On January 16, CAC released the latest batch of C-NCAP safety crash test results, and BYD Leopard was awarded a five-star safety rating with a combined score of 88.6 percent and passed the "electric safety" evaluation. This is the first hardcore endorsement from a third-party authority since the launch of the Ocean Leopard model, with its aesthetic, safety, handling and efficiency advantages. Since the implementation of the C-NCAP Administrative Rules (2021 version), the overall score rate of the Ocean Leopard model has ranked first on the overall list.
The test difficulty is enhanced, and the new C-NCAP regulations have higher gold content. The model participating in the test is the BYD Seal 700km long-range rear-drive version with a market guide price of 262,800 RMB. According to the latest "C-NCAP Management Rules" (2021 version), the Seal has passed a number of high standard safety evaluations. 2021 version of the "Management Rules", based on the 2018 version, has significantly increased the difficulty of the test, and the "gold content" of the test results is higher. "higher. Just take the original frontal "40% overlap deformable barrier crash test" as an example, in the 2021 version of the "management rules" upgraded to "frontal 50% overlap moving progressive deformation barrier (MPDB) crash test ", simulating a frontal collision of two vehicles at a speed of 50km/h, the kinetic energy of the collision in the test is greatly increased, and the test of the vehicle structure is of course greater.
As shown in the chart, in terms of occupant protection, which is of most concern to users, the Seal scored a record 92.27 %. The crash score is 58.211 out of 60, the whiplash score is 7 out of 7, the child occupant protection score is 3 out of 3, and the side air curtains and E-CALL device are equipped with 4 out of 5 additional points. In terms of active safety, Seal also received a score of 92.97% due to the excellent performance of various features.
Based on CTB technology to create a pure electric exclusive safety body structure, Seal designs a high standard of safety for users
"Safety is the biggest luxury of electric vehicles", it is said that high standard of safety is designed, and this statement is fully verified in Seal models. Based on the advanced e-Platform 3.0, Seal is equipped with the first CTB battery-body integration technology. This technology is inspired by honeycomb aluminum panels, which is also very understandable in concrete terms. For example, two pieces of paper stacked on top of each other can still be easily folded into various shapes, but if a special honeycomb structure is added in the middle of the two pieces of paper and glued together, it can become a material with better structural strength and toughness. Similar forms are almost ubiquitous in daily life, as small as courier packing boxes, as tough as cushioning devices for air-dropped armored vehicles, and as light-weight, high-strength honeycomb aluminum sheets, which are more widely used in the aviation industry.
Thanks to this inspiration, BYD's engineers developed a sandwich structure for the entire vehicle consisting of a battery pack top cover integrated with a body floor, a "blade battery" and a battery tray. In particular, the aforementioned "honeycomb special structure" has become a "blade battery", which is different from the general soft pack or cylindrical battery cells. This structure of the CTB battery system can give full play to the strength advantages of the "blade battery" as both an energy body and a structural component, which not only solves the problem of volume utilization of the battery system and obtains a longer range by virtue of the energy density advantage of the system, but also eliminates the traditional sense of the underbody, and can play a significant role in strengthening the body, which brings a series of benefits to the overall vehicle design, interior space, ride comfort, NVH, handling performance and safety performance. handling and safety performance.
The CTB battery system also creates a more complete and efficient crash stress transfer path with the body-in-white, which can better absorb kinetic energy when the vehicle is involved in a crash. Compared with the common CTP structure, the longitudinal force transfer performance of Seal's CTB battery system has been improved by 83%, and the structural safety of the vehicle has been improved by 50%; the lateral force transfer performance has been improved by 125%, and the structural safety of the vehicle has been improved by 45%; the intrusion of the whole vehicle's side pillar has been reduced by 45%, which is called the electric car that can't be stopped. In addition, the Seal's full-frame subframe helps to disperse stress, and its special collapse structure design can absorb collision energy more efficiently and protect the occupants of the car.
Safety is just one of the many benefits of the Seal model. With the "four firsts", the Seal has an inherent sporting talent that can fully meet the high standard of driving fun demanded by young users in the new energy era. In addition, the high efficiency, good range and fast charging of Seal have also been highly recognized by users and media. In the "2022 New Energy Winter Test" organized by a well-known media, the Seal withstood the test of low temperature and severe cold, and among more than 60 test vehicles, the Seal model ranked top in many tests, and the product reliability was effectively verified. As of the end of December 2022, BYD Seal's cumulative sales exceeded 50,000 units in just less than five months. With its hard-core product strength, the good-looking, good-driving, fun and safe BYD Seal is definitely the best choice for high-quality travel in the new energy era.
