Xiaomi's automotive technology conference was held in Beijing at two o'clock this afternoon, and Lei Jun told everyone what the "Spring Festival Gala of the car circle" was in a few hours, and even, in theory, this is just a "trailer".
The first half of the press conference mainly dismantled the main key technologies of Xiaomi cars:
1. Motor.
As the core of electric vehicles, the motor is the main component that drives the car, and Xiaomi brought it this timeXiaomi Super Motor-V6 V6SThe speed reached 21,000 rpm, which has surpassed the level of Tesla and Porsche's motors.
At present, the Xiaomi V6 and V6S motors have been mass-produced, and will be equipped with the Xiaomi SU7 for the first time. Among them, the V6 has a maximum power of 220kW, a peak torque of 400N·m, and a maximum horsepower of 299PSThe V6S has a maximum power of 275kW, a peak torque of 500N·m, and a maximum horsepower of 374PS.
Xiaomi also plans the V8S motor and laser winding rotor technology in the future, the V8S speed can reach 27200rpm, and it is expected to be on the car in 2025, and the rotor technology speed can reach 35000rpm, and the laboratory pre-research has been realized.
2. Battery
For pure electric vehicles, the public generally has concerns about battery performance and safety.
At the press conference,Xiaomi unveiled its 800V SiC high-voltage platform jointly developed with CATL。There is no false standard in the data, reaching 871V, Xiaomi's 800V battery pack adopts CTB integrated body technology, and has the highest 77 in the worldThe 8% volume efficiency of the battery pack, the thickness of the battery pack and the bottom plate is only 120mm, which can bring more space to the passenger compartment.
According to the data provided at the press conference, the theoretical upper limit of the battery pack platform of Xiaomi cars reached the maximum power of 150kWh, and the CLTC range was 1200+km, but in order to weigh the cost, the final battery capacity was selected to be 132kWh, which still maintained a CLTC range of 1000+km.
In response to security issues, the entire platform is wrapped with 14 layers of hard-core physical protection, and the industry's first battery cell inversion technology is adopted.
At the press conference, Xiaomi Auto also challenged the "King of Winter Trams", and Lei Jun introduced its heat pump system, which can absorb heat from the cold air outside.
3. Body
Xiaomi has also cooperated with the National Key Laboratory of Materials to develop its own alloy materials"Xiaomi Titan".。The maximum clamping force of 9100t is independently designed"Xiaomi Super Big Die Casting".Equipment.
4. Intelligent driving
Intelligent driving is a technology that Xiaomi has been focusing on for a long time. The three technologies of zoom BEV, road large model, and super-resolution occupancy network technology are combined to achieve a higher precision intelligent driving experience.
5. Smart cockpit
In terms of driving experience, the Xiaomi Su7 smart cockpit provides up to 5 screen linkageThe car machine is equipped with a Qualcomm Snapdragon 8295 chip。Using Xiaomi's surging OS car machine system, the mobile phone and the car machine can be seamlessly connected across terminals, and even supports wireless CarPlay, AirPlay and iPad rear row expansion, Apple users can also have a good experience.
Originally, this conference will focus on technology and will not involve product releases, but in order to respond to the expectations of fans, the second half of the conference also brought some information about Xiaomi cars, including color matching, interior, space, speed performance, etc.
AbsolutelyThe ** that everyone is most concerned about is still not public, but Lei Jun also said".90,000 9 is impossible, but anyone with this kind of performance and configuration has to be more than 400,000!So 140,009 doesn't need to talk about it anymore, we still have to respect technology. ”
