On January 16, "CAIC Center" released the latest batch of C-NCAP safety crash test results, and BYD Seal won the five-star safety evaluation with a comprehensive score rate of 88.6%, and passed the "electrical safety" evaluation. This is the first hardcore endorsement from a third-party authority since the launch of the marine "Leopard" model with the advantages of aesthetics, safety, handling and efficiency. Since the implementation of the C-NCAP Management Rules (2021 edition), the overall score rate of Seal models has ranked first in the overall list.
The difficulty of the test has increased, and the new C-NCAP regulations have higher gold content
The model participating in the test is the 700km long-range rear-drive version of the BYD Seal, with a market guidance price of 262,800 yuan. According to the latest C-NCAP Management Rules (2021 edition), seals have passed a number of high safety standards. The 2021 version of the "Management Rules", on the basis of the 2018 version, greatly increases the difficulty of the test, and the "gold content" of the test results is higher. Taking the original frontal "40% overlapping deformable barrier crash test" as an example, it was upgraded to "frontal 50% overlapping moving progressive deformation barrier (MPDB) crash test" in the 2021 version of the "Management Rules", simulating a frontal collision between both vehicles at a speed of 50km/h, and the collision kinetic energy in the test was greatly improved, and the test of vehicle structure was of course greater.
As shown in the figure, in terms of occupant protection, which users are most concerned about, seals scored a record 92.27%. The collision score was 58.211 out of 60, the whiplash score was 7 out of 7, the child occupant protection score was 3 out of 3, and 4 out of 5 for the side air curtain and E-CALL device. In terms of active safety, Seal also received a score rate of 92.97% because of its outstanding performance in various functions.
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 greatest luxury of electric vehicles", it is said that high standards of safety are designed, and this sentence has been fully verified on the Seal model. Based on the advanced e-platform 3.0, Seal is the first to use CTB battery body integration technology. This technology is inspired by honeycomb aluminum plates, which are also very well understood specifically. For example, two sheets of paper stacked together can still be easily folded into various shapes, but if you add a honeycomb-like special structure between the two sheets and bond them together, it can become a material with better structural strength and toughness. Similar forms are almost ubiquitous in daily life, from small express packaging boxes to powerful cushioning devices for air-dropped armored vehicles, and lightweight, high-strength honeycomb aluminum plates, which are more widely used in the aviation industry.
Thanks to this inspiration, BYD engineers developed a sandwich structure consisting of a battery pack with an integrated underbody panel, a "blade battery", and a battery tray. In particular, the aforementioned "honeycomb special structure" has become a "blade battery", different from the general soft bag or cylindrical cell, this structure of the CTB battery system can give full play to the "blade battery" is both an energy body, but also can be a structural part of the strength advantages, not only to solve the battery system volume utilization problem, with the system energy density advantage to obtain a longer mileage, but also because of the elimination of the traditional sense of the body floor, can play a significant role in strengthening the body, It brings a series of advantages to the vehicle's styling design, interior space, ride comfort, NVH, handling performance and safety performance.
The seal has a body torsional rigidity of 40,500Nm/°, which is comparable to a million-class luxury car. The CTB battery system is also able to form a more complete and efficient crash stress transfer path with the body-in-white, which can better absorb kinetic energy when the vehicle collides. Compared with the common CTP structure, the longitudinal force transmission performance of the CTB battery system of Seal is increased by 83%, and the safety of the interior structure is increased by 50%. The lateral force transmission performance has been improved by 125%, and the safety of the interior structure has been improved by 45%; The number of side pillar collisions in the whole vehicle has been reduced by 45%, which can be called an electric vehicle that constantly crashes. In addition, the seal's full-frame subframe also helps to disperse stress, and its special collapse structure design can absorb crash energy more efficiently and protect the safety of occupants.
Safety is just one of the many advantages of the SEAL model. With the blessing of the "four firsts", Seal has an innate athletic talent, which can fully meet the high standard requirements of young users for driving pleasure in the new energy era. In addition, seals' high efficiency, good battery life and fast charging have also been highly recognized by users and media. In the "2022 New Energy Winter Test" event organized by a well-known media, the seal was forbidden to withstand the test of low temperature and cold, and in the same competition of more than 60 test models, many test results of seal models ranked among the best, and the reliability of the product was effectively verified. As of the end of December 2022, BYD Seal has exceeded 50,000 units in less than 5 months. With its hardcore product strength, BYD Seal is beautiful, open, fun and safe, which is definitely the best choice for high-quality travel in the new energy era.
