How to define a good car? BYD is seriously answering with its own standards: Take Bill Han as an example, from the research and development stage, it puts safety and quality first. After massive simulation experiments and real vehicle tests, high-quality production vehicles are manufactured on the basis of large samples and delivered to users.

With the three benchmarks of safety, performance and luxury, China has become the first and only automobile brand with a monthly sales volume of over 10,000 in the history of the medium and large C-class car market, breaking the market structure in which German brands absolutely dominate the market. By the end of 202 1, Korea continued to rise, and formed the first group in the domestic medium and large C-class car market. The total sales volume of Korean models exceeded 50,000.

In March, 20021year, BYD held the activity of "Being Tested-BYD's Quality Journey". Different from other car companies, BYD is showing shiny new cars, but it is showing experimental scrapped cars. Let users truly see BYD's quality standards and intentions through every scrapped car that has experienced "countless storms".

At all costs, achieve "industry-leading" safety performance.

In BYD, engineers will define the vehicle performance one by one according to the "LACU strategy" in the model definition stage, and the main indicators are divided into more than a dozen items. Take Bill Han as an example, its safety performance is defined as "L" level, that is, it has reached "leading position in the industry". (LACU strategy -L: leading position in the industry; A: Ranked among the leading positions in the industry; C: competitive in the industry; U: industries that are not competitive are not competitive)

During the development of Korean car models, BYD has carried out a lot of simulation designs for safety, and simulated the passive safety of the whole vehicle, system, subsystem and parts in the event of collision through mathematical models. According to the problems exposed in the experiment, continuous optimization is carried out, and finally the design expectation of "L" level is achieved.

In order to reach the safety level defined in the plan, Han adopted a high-safety body, in which 43 military-grade thermoformed steel bars were used, and BYD Han used 97kg thermoformed steel bars in the body-in-white, which not only ranked first among China brand production cars, but also nearly doubled the second, creating "invisible" protection and safer driving experience for consumers.

Security testing is not only testing, but more importantly, it is really for the safety of users. BYD invested heavily in building a vehicle collision laboratory, which can meet the requirements of national standards, American standards, European standards and other laws and regulations and C-NCAP evaluation and testing. On the basis of relevant standards, more experimental methods and means are designed. In addition to common collision tests such as frontal collision, side collision and rear-end collision, Han also conducted more rigorous and complicated safety tests according to the complexity of road traffic and the characteristics of new energy vehicles, such as frontal collision with top speed 120km/h and ultra-difficult small offset collision, so as to protect users to the maximum extent.

Life safety in extreme traffic accidents.

BYD has also adopted a number of dummies far higher than the industry standard, and has complete dummy families of different ages and genders. The temperature of the dummy showroom needs to be controlled at 20 -22 degrees, and the cost is as high as tens of millions, which can restore the real situation of the real owner and passengers with different seats, sexes, ages and sitting postures in the car to the maximum extent and provide a more perfect safety protection scheme.

There are all kinds of "car abuse" in the world, just to let users feel at ease on the road.

China has a vast territory, with great differences in topography, road conditions, weather temperature and environmental humidity. BYD collected real data covering all parts of the country, such as road condition data, temperature data, humidity data, and simulation experiments in various extreme scenes, just to restore the real car scene of each user.

Behind Henkel's long and reliable life is the accumulation of numerous tests that fully simulate various extreme usage scenarios of consumers. According to industry standards, the vehicle life of 1.5 million kilometers is enough to cover 90% of users' needs. The design life of most high-end cars on the market is 300,000 kilometers, while the vehicle life target of Korean models is 600,000 kilometers, which is twice that of most high-end cars of the same class. But high quality is not the pursuit of figures on the odometer, but to meet the needs of users to the greatest extent.

BYD is not only satisfied with the strength and accuracy of "real vehicle road test", but also adopts a large number of international advanced precision test equipment. "24-way road simulation test" is one of the most rigorous links, which can restore 95% of the road conditions that users may encounter, and the 4-post test bench used by most brands can restore 70% at most. The Korean test vehicle will bump on the bench for 45 days and nights. This test takes 3 rounds, which is equivalent to 1 10,000 kilometers traveled on the real vehicle test road, which is more than 3 times the test volume of most similar vehicles.

In addition, Han also completed the "three highs" test in harsh and extreme environment, which not only withstood the environmental cabin test of various scenarios with temperature coverage of -40 -80, but also used the team self-driving mode to test the vehicle performance from Hainan, yakeshi to Turpan, and test the adaptability of charging facilities along the way.

The adaptability of charging piles is a headache for many users. At present, there are many kinds of charging piles in the market with different specifications and even different voltages, which greatly limits the application scope of electric vehicles. BYD's charging pile adaptation test team conducts tests all over the country all the year round. In order to adapt to the better booster charging technology, we will not let go of the old piles that will be eliminated soon. BYD strives to complete the point-to-point test deployment before users encounter problems, thus ensuring its strong national adaptability and high charging efficiency.

Strictly start from ourselves and promote the all-round progress of China standards

It can be seen from Han that BYD's safety and durability test standards are extremely strict, and it will strive for the final 1% safety with high investment. But all this is a process of accumulation. In 2009, BYD e6 completed the first collision of pure electric vehicles in China; 20 1 1, BYD S6 became the first domestic SUV with five-star standard in China. Since 20 13, BYD has selected at least one model every year and achieved five-star results.

Since the establishment of BYD Safety Testing Center, thousands of valuable "BYD standards" have been accumulated, which has consolidated the technical background and formed high-quality standards. At the same time, BYD has also invested a lot of energy and unremitting research in safety, and actively participated in promoting the gradual improvement of relevant national safety regulations and standards. It is predicted that in 2022, China's automobile safety standards will become the most stringent standards in the world.

Behind the constant pursuit of stricter standards is BYD's engineer culture of Excellence, which is BYD's enterprising spirit of "grinding a sword for ten years". It constantly drives itself, breaks through key core technologies and refines BYD's high quality.
