Want to know Xiaomi SU7？ Just read this one!
● Xiaomi 澎湃 OS intelligent cabin system can realize cross-end interaction.
In terms of intelligent cabin hardware, the SU7 center console includes three pieces of screen hardware:
1. 56-inch HUD head-up display (10°x3.6° wide viewing angle, 1500: 1 contrast, 13000 nits brightness)
2. Display system of overturning instrument with 7.1-inch screen.
3. 16.1-inch 3K large screen (aspect ratio 16 to 10, 91.7% screen ratio, 1024-level dynamic dimming)
The intelligent cabin system is built with the latest and strongest car gauge chip in the current production car.Qualcomm Snapdragon 8295, the computing power is up to 30TOPS of ops. System software is Xiaomi’s strong point, equipped with Xiaomi’s own research.澉湃 OS(Xiaomi HyperOS) system, has the characteristics of fast start-up, fast upgrade and convenient operation. Based on Xiaomi’s strong consumer electronics product ecology, SU7 also has a strong interconnected ecology, spanning many aspects of people, cars and homes. The system also specially considers the security of accounts. When logging in different user accounts, the self-defined layouts (desktop layout, sitting posture, driving habits, etc.) of each account are independent and invisible to each other, and the private data will be automatically isolated when the vehicle is sent for repair, so that the staff cannot view or call the information. The system logically supports the flexible framework and the adjustment of window size and position. In addition, the co-pilot can also slide down the control center from the right side to directly adjust the co-pilot seat and air conditioner. Rapid response is also a major feature of the intelligent cabin system. 澎湃 OS supports a 1.49-second cold start, and it takes about 3 minutes and 30 minutes to upgrade the OTA package and the whole car package respectively.
In terms of the interconnection between people and vehicles, 澎湃 OS system supports mobile phone cross-terminal screen projection, and mobile phone applications can be directly projected on the central control screen to realize functions such as short video brushing, web browsing and online conference. A standardized interface is preset behind the driver and passenger, which can be externally connected with devices such as Xiaomi tablet or Apple iPad. After the Xiaomi tablet and Apple iPad are connected, they can continuously supply power through the 22.5W magnetic interface. At the same time, the tablet can also be connected to the car machine to directly control some hardware on the car, including more than 30 car control functions such as navigation, seat and air conditioning. The standardized interface is not limited to flat plates, but also can be externally connected with equipment such as car hangers with a maximum load of 20 kg. In order to take care of Apple users, 澎湃 OS fully supports wireless CarPlay handcart interconnection, and can realize audio and video circulation based on AirPlay.
In terms of car-home interconnection, SU7 can realize remote control of 1,000+meters of home equipment by means of secret-free connection with the same account, and even support the setting of automatic scene linkage, so as to quickly adjust the air conditioning temperature at home and turn on the lights when driving home from work. Using the magnetic interface around the central control panel, SU7 also prepared a special physical keyboard for the control panel and an aromatherapy system. At the same time, Xiaomi Ecology will be opened to a third party to realize the status reminder of child safety seats (whether to fasten seat belts) and call Xiaomi flat-panel camera (check the status of children in the back row).
● Motor: 21,000 rpm super motor has been put into mass production, and the speed exceeds Model Slaid.
(|) There are two power versions, the 668km single-motor rear-drive version and the 800km dual-motor four-wheel drive Max version. The two cars are slightly different in hardware configuration and power parameters. In terms of motors, the rear-drive is equipped with Xiaomi Super Motor V6 (United Automotive Electronics), and the Max (four-wheel drive) is the Xiaomi Super Motor V6s of UMC. Both motors have the highest speed of 21000rpm. However, in terms of motor speed, the "20000+ Club" has many rivals, including Model Slaid (20000 rpm), Zhijie S7 (22000rpm released from Huawei DriveONE production car) and Krypton 001 FR(21000rpm). The speed of Xiaomi super motors V6 and V6s has reached the leading level in the industry.
In terms of power parameters, the V6 motor with single motor version has a maximum power of 299Ps(220kW), a peak torque of 400N·m, an acceleration time of 5.28s from 0 to 100 km/h and a maximum speed of 210 km/h.. The dual-motor four-wheel drive version uses the V6s super motor. The maximum power of a single motor is 374Ps(275kW), the peak torque is 500N·m, and the power density is 6.78kW/kg. After the combination of two motors, the total power of Xiaomi SU7 Max system is 673Ps(495kW), the total peak torque of the system is 838N·m, the time of 0-100km/h is 2.78s, and the maximum speed is 265 km/h. The parameter performance is better than that of Model S dual-motor all-wheel drive version (corresponding parameters 3.2s and 250km/h), but lower than that of Plaid version (corresponding parameters 2.1s and 350km/h).
Considering that the Max version deliberately sets the Boost mode button on the steering wheel (the maximum torque output lasts for 20 seconds) and sets the ejection start mode in the driving mode, I guess the strongest state can only be turned on in a specific mode. After all, it is very likely to cause danger if people who are unprepared are driven by such rapid acceleration. In addition, SU7 also provides users with an infinitely adjustable driving mode, including 10 adjustable items, and personalized settings can be uploaded to Xiaomi community to share with other riders.
At the press conference, Mr. Lei also announced the next-generation super motor developed by Xiaomi: V8s. At the press conference, it was revealed that the motor has been mass-produced and it is planned to be put on the train in 2025. Compared with V6 and V6s, V8s uses silicon carbide electronic control module, with the highest speed of 27000rpm, the maximum motor power further increased to 578Ps(425kW), the peak torque of 635N·m, and the highest efficiency of 98.11%. The power density is 10.14kW/kg.
In order to withstand ultra-high speed, the rotor is made of a new generation of 960MPa silicon steel material, and the idea of "stepped" design of rotor silicon steel sheet is adopted. At the same time, in order to improve the temperature control ability and prevent overheating at high speed, the V8s super motor also adopts two-way all-oil cooling technology, including the design of stator double-cycle three-dimensional oil circuit and rotor S-type oil circuit. At the meeting, it was even revealed that a super motor is still in the pre-research stage of technology, which uses laser winding rotor technology and has a maximum rotation speed of 35000rpm in the laboratory environment.
In the research and development of high-speed motors, the technical routes adopted by different brands are slightly different. For example, Model Slaid motor uses carbon-coated motor rotor technology, and Huawei DriveONE uses silicon steel sheets as the rotor of Xiaomi Super Motor.
