The independent brands that have risen up in the cracks of the joint venture brand have achieved quite good results in recent years, and with the advancement of technology, the competitiveness of the system has been formed in research and development, manufacturing and sales, and the competition with the joint venture brand has become a reality. Recently, we were invited to visit the three laboratories and achievement exhibitions of BYD headquarters, from a professional perspective and many achievements across fields, let us re-understand BYD, a "not simple" car company.
Learn about BYD's inner show
The main visit is BYD's three laboratories, namely the collision laboratory, NVH laboratory and EMC laboratory, because the laboratory can not take pictures, we can only rely on part of the network map and text to outline the outline of BYD's three laboratories.
The first is the collision laboratory, as the name suggests, this laboratory is the place to test the safety of the whole vehicle, therefore, the laboratory is full of tracks in all directions, which is convenient for the body to carry out frontal collisions, bias collisions and other items at different angles, deeply simulate the collision results in reality, and test and adjust the various indicators of the product according to the collision data.
In the parking lot outside the laboratory, nearly 100 vehicles that were scrapped by collisions were densely parked, and from here we can also see the intensity of BYD's crash test. In addition, the crash test is naturally inseparable from the dummy, in a constant temperature and humidity room in the collision laboratory, dense dummies are placed on a special stretcher, according to byddio official introduction, the average price of a dummy is as high as 2 million, and the most expensive up to 7 million, even a small baby dummy, the price is more than 100,000 yuan, it is reported that the total value of the dummy in this room is tens of millions.
Next is BYD's NVH laboratory, before entering the laboratory, the official promotional video uses a body frame to vibrate the form of a song, so that we can simply understand the characteristics of sound transmission, and there is a feeling of returning to the classroom in an instant. The laboratory is covered with a large amount of sound-absorbing material, which can reduce the noise in the laboratory to individual dB.
Located in the center of the laboratory bench, can simulate the NVH performance of the vehicle at different speeds, a brand new model, from the body in white to carry out NVH testing, so as to continuously adjust the NVH of the vehicle according to various indicators, from the structure began to solve the vibration, noise.
The last laboratory was emc labs, which cost up to 100 million yuan and had walls covered with absorbing material. The laboratory mainly tests the electromagnetic radiation compatibility, in addition to testing the electromagnetic radiation of the vehicle itself, it also tests the stability of the vehicle for the external strong electromagnetic radiation environment.
The three laboratories reveal not only BYD's investment in technology, but also show the attitude of THE BYD brand in development, based on technology in the market, continuous investment, providing a steady stream of impetus for BYD's take-off.
Technological innovation
Next, we visited BYD's Concierge Building, which shows the history of brand development from multiple dimensions such as BYD's development nodes, industries and technologies. Among them, the industry is concentrated from the four aspects of automobile, rail transit, new energy and electronics.
The most shocking thing in the concierge building is BYD's huge innovation wall, which is densely covered with various patents, showing BYD's technological progress and honor. The next tour is the DM technology of BYD's one-step market, the development mileage and technological progress from the first generation, the second generation to the third generation, and the differences and advantages of DM-i and DM-p technology systems.
Of course, there is also a unique blade battery of BYD, for this reason, BYD also specially showed us the blade battery and ternary lithium battery acupuncture experiment, although separated by glass, but after the ternary lithium battery acupuncture, the instantaneous burst of flame still let us feel the heat from the paving, and the blade battery after the needle puncture, there is no fire burning, only the voltage has a slight change, through the needle prick comparison, can clearly perceive the safety gap between the ternary lithium battery and the blade battery. Next, we continued to visit BYD's electronic control, motors, steering systems, braking systems, etc., which CAND can produce in-house.
Summary: From this trip to BYD's headquarters, we can more clearly understand the development process of the brand, BYD's technology and innovative development are indeed worthy of our admiration, thick accumulation, not a simple word, but bydir since its inception to practice the development strategy. Especially the recently released DM-i series models, the hot market feedback has made the market recognize BYD's technical heritage, quite a kind of "ten years of cold window no one asks, in one fell swoop to become famous in the world" marvel, which is also a microcosm of the independent brand represented by BYD.
