Before the press conference, Lei Jun said in a preview: “Only technology will be released, not products.” However, with the official debut of Xiaomi’s first model, SU7, details of more models and products have become increasingly clear.
At this technical conference, Xiaomi Motors “pre-released” its first product, Xiaomi SU7, and its appearance design, performance, battery life, safety and other details were publicly unveiled for the first time. According to Lei Jun, Xiaomi’s first model is positioned as a C-class high-performance ecological technology sedan. The body size is 4997 mm × 1963 mm × 1440 mm, the wheelbase is 3000 mm, and the drag coefficient is Cd 0.195. It only takes 2.78 seconds to accelerate from 0 to 100 km/h, the highest Speed of 265 km/h. At the same time, the Xiaomi SU7 is available in three colors.
Lei Jun also has thoughts on why he chose a sedan as the first model. “Making a sedan has a better chance of becoming a masterpiece of our era, so we firmly chose to make a sedan. From a technical point of view, making a sedan is more difficult than making an SUV, so among all the technical decisions, Xiaomi chose the most difficult and The farthest road.” Lei Jun said.
It is worth noting that Xiaomi SU7 has two endurance versions, with CLTC operating mileage of 668km and 800km, respectively. Among them, the MAX version uses 800V fast charging, and the battery life can reach 220 kilometers after 5 minutes. After this data was released, some netizens began to speculate on the version and configuration of the new car.
Although it is still several months until the model is launched, the price has become the focus of the attention of consumers and Xiaomi fans after many details were announced. On the eve of the press conference, Lei Jun warned that the price of SU7 may be a bit expensive, but it must make everyone feel that it is expensive and the experience will exceed expectations. Xiaomi Motors has not disclosed the price, but Lei Jun said at the scene: “Don’t shout 99,000 yuan, it’s impossible! There is no need to talk about 149,000 yuan; we must still respect technology.”
Clarify future goals
Xiaomi Motors does not have a clear target model compared with other model releases. Lei Jun said: “We have done a lot of research and hope to make a dream car that can carry all the aspirations of everyone; in terms of mechanical qualities such as driving performance, we hope to be comparable to the Porsche Taycan Turbo. in terms of intelligence, we hope to be comparable to Tesla Model S; it also has the most leading technology and the richest ecology.”
In Lei Jun’s view, Xiaomi Auto’s goal is to create a mobile smart space that looks good, is easy to drive, and is comfortable and safe. At this technical conference, Xiaomi Motors also announced that Xiaomi Pascal OS is officially on the road. “With the release of Xiaomi’s automotive technology, Xiaomi’s ‘Full Ecosystem for People, Cars and Homes’ has officially closed the loop.” Lei Jun said Xiaomi’s tablet application ecosystem has seamlessly integrated into cars. It is understood that Xiaomi Auto’s entire cockpit system upgrade only takes 3 minutes, and the entire vehicle upgrade only takes 30 minutes.
Lei Jun believes that the ultimate realm of smart electric vehicles is the technological leapfrog and integration of humans and vehicles. Only the most advanced technology and the most complete ecology can achieve the integration of people and vehicles and control driving freely. Cui Dongshu, Secretary-General of the Passenger Car Market Information Joint Association, believes that the new energy vehicle market is becoming more mature and market competition has entered a fierce stage. Car companies are using various methods to break through. As a technology company, creating a full ecological label will also benefit Xiaomi Auto’s standing to stand out from the competition.
After achieving a closed ecological loop, Lei Jun also set future goals for Xiaomi Motors. Lei Jun said that Xiaomi Motors will become one of the top five automobile manufacturers in the world through 15 to 20 years of hard work.
The automotive industry continues to change.
The current automobile industry has entered a period of great change that occurs once a century. Under the wave of electrification, the design of major automobile systems has undergone earth-shaking changes. Advanced materials accelerate their “onboarding” due to their unique performance advantages. In this context, advanced materials such as aluminum nitride, 3D printing technology, etc., have many applications and development potentials in the new energy automobile industry.
The application of aluminum nitride in the field of electric vehicles mainly involves the following aspects:
1) Electronic devices: In electric vehicles, high-power electronic devices (such as IGBT modules) require high-performance heat dissipation materials to effectively dissipate heat and increase the life of the electronic devices;
2) Engine parts: AlN ceramics have high wear resistance and high-temperature stability and can be used to manufacture engine parts for electric vehicles, such as pistons and cylinder liners, which help to improve engine efficiency and reduce friction losses, thereby improving the performance of electric vehicles. Performance and range.
3) Charging equipment: AlN can manufacture connectors and plugs for electric vehicle charging equipment. These components must have high wear and temperature resistance to meet the requirements when charging electric vehicles.
4) Sensor applications: AlN can also be used in sensor applications, such as temperature and pressure sensors, to monitor various parameters of electric vehicles.
What are the application prospects of 3D printing in industries such as aluminum nitride?
The application prospects of 3D printing in industries such as AlN are very promising:
1) Manufacturing AlN ceramic parts with complex geometric structures;
2) Customized production according to specific needs;
3) Reduce the production of materials, improve material utilization and reduce costs.
Overall, combining the two has broad prospects with the continuous advancement of 3D printing technology and the development of AlN materials. It can be used for various high-performance applications, but further research and development are still needed to solve Potential technical challenges.
