  After 1003 days of announcing its entry into the electric vehicle industry, Xiaomi Automobile officially made its debut. On December 28th, Xiaomi Group held the Xiaomi Automobile Technology Conference in Beijing. The design, performance, battery life, safety and other details of Xiaomi SU7, the first work of Xiaomi Automobile, made its first public appearance.

  "Xiaomi decided to invest ten times, start with the underlying core technology, seriously build a good car, and through 15 to 20 years of hard work, become the top five automobile manufacturers in the world and strive for the all-round rise of China’s automobile industry!" Lei Jun, founder, chairman and CEO of Xiaomi Group, said at the scene that Xiaomi Automobile is a major leap for Xiaomi Group from the mobile phone industry to the automobile industry, and it is also a key leap for the complete closed loop of "the whole ecology of people, cars and homes".

  Lei Jun said that from the beginning, Xiaomi Automobile insisted on starting from the underlying core technology, insisting on positive research and development, and deep self-research on key tracks. At present, Xiaomi Automobile has invested more than 10 billion yuan in the first phase of R&D, and the R&D team has more than 3,400 engineers, including thousands of top technical experts at home and abroad in key fields.

  This conference officially revealed the progress and breakthrough of five core technologies of Xiaomi Automobile, including electric drive, battery, large die casting, intelligent driving, intelligent cockpit and other key areas, which can be called a comprehensive display of Xiaomi’s 13-year technology accumulation.

  Among them, in the field of industrial hard technology, Xiaomi has demonstrated the scientific and technological strength of self-developed manufacturing hard core, and has the leading intelligent manufacturing strength of complete automobile industry. For example, the super motor HyperEngine V8s independently developed and produced by Xiaomi has a rotational speed of 27200rpm, ranking first in the world in terms of mass production motor speed; Xiaomi has developed the integrated battery technology of CTB, and the world’s first battery inversion technology has achieved the highest battery integration efficiency of 77.8% in the world. In order to ensure the battery performance and quality from the source, Xiaomi even built its own battery pack factory.

  In addition, Xiaomi has independently developed "9100t super large die-casting cluster" and self-developed die-casting alloy material "Titan alloy", becoming the only automobile manufacturer in China with self-developed large die-casting and die-casting materials. At present, the industry is winding up the tonnage of clamping force of large die casting. Xiaomi firmly takes the road of full-stack self-research, from self-research materials and equipment cluster systems to finished castings, and has completed the full-stack self-research of almost all links in the large die casting industry chain.

  In the field of intelligent soft technology, Xiaomi has demonstrated the unique advantages of "technology giant, eco-car-making" and promoted the integration of automobile industry, consumer electronics industry and intelligent ecology. For example, based on Xiaomi 澎湃 OS, Xiaomi intelligent cockpit has realized the bottom reconstruction, evolved for the car, and created an advanced intelligent mobile space; In the field of intelligent driving, Xiaomi industry launched three key technologies, namely adaptive zoom BEV technology, large road model and super-resolution occupation network technology.

  In addition, the comprehensive empowerment of AI has also become a new bright spot for Xiaomi Automobile to integrate cutting-edge technologies and achieve innovative breakthroughs. For example, in addition to the first road model in the industry, Xiaomi has also developed the world’s first mass-produced "end-to-end perception decision-making model" for the parking service scene of intelligent driving, which can observe and dynamically adjust the parking spaces in mechanical garages and other ultra-difficult parking spaces in real time.

  Zhang Xiang, director of Vodafone Digital Automobile International Cooperation Research Center, told the Securities Daily that Xiaomi currently adopts the mode of self-purchasing equipment and self-building factories in core areas such as batteries and die casting, which is a common practice in the current industry. For example, Weilai makes its own motors, Tesla has a battery assembly plant, and BYD has mastered the most self-developed technologies for core components. Car companies build their own factories in these fields, on the one hand, because the production capacity of some core components is not very large, the supply chain is not very mature, and outsourcing faces supply chain security problems; On the other hand, the prices of these core components are relatively high and the profits are relatively high. If you choose to build your own factory, you can enjoy the industry dividend. If you outsource it completely, the technical content and profits of Xiaomi Automobile will be greatly reduced.

  At the end of October this year, Xiaomi announced a comprehensive upgrade of the group’s strategy, from "mobile phone ×AIoT" to "people, cars and homes are all ecological", and cars have become the most important part of Xiaomi Group’s strategy. Lei Jun announced that with the addition of Xiaomi Automobile, Xiaomi’s "full ecology of people and cars" was officially closed.

  Lei Jun introduced that "the whole ecology of people, cars and homes" is a super-intelligent ecology that comprehensively opens up people, cars and homes, realizes seamless connection and real-time collaboration of hardware equipment, and drives industrial chain partners to create a people-centered and active service. Xiaomi 澎湃 OS has opened up more than 200 categories including Xiaomi Automobile. In the past 13 years, Xiaomi has laid out 12 technical fields and 99 sub-tracks. Based on the principle of "deep integration of soft and hard, comprehensive empowerment of AI", Xiaomi has formed a "fusion technology stack" to continuously empower product development and manufacturing.
