The rear-wheel drive model was not introduced much at this launch, but the corresponding data was announced. The battery is equipped with a 73.6kWh lithium iron phosphate battery provided by Verdi, with a CLTC range of 668km. the system supports 400V fast charging, and charging for 15 minutes can increase the range by about 330km.
Max version equipped with Ningde Times ternary lithium kirin battery, the whole battery system adopts CTB (battery and chassis integration) technology, battery height 120mm, capacity 101kWh, CLTC range (four-wheel drive) 800km. the whole system adopts the 871V (some other brands in the publicity will be called "quasi-900V") charging platform, charging system support 400V fast charging, charging 15 minutes can increase the range of about 330km. The whole system adopts 871V (some other brands may call it "quasi-900V" in their publicity) charging platform, which is extremely fast, and the data announced on the site shows that 5 minutes of charging can extend the range by 220km, and 15 minutes can extend the range by 510km.
In terms of safety, the complete battery system has 17 layers of insulation protection, the side of the battery cell is filled with 165 pieces of aerogel insulation material, and the use of thermoformed steel, high-strength steel and other materials to manufacture components such as bezels and beams. The battery also detects the condition of the battery in real time through the car-cloud cooperative network (800 detections in 1 second, and it takes only 4ms to disconnect the battery in an emergency). Even in the event of an unavoidable extreme situation, the inverted cell technology allows the energy to be released downwards, maximizing the safety of the cabin.
For the battery in extreme cold environments commonly encountered discounted range and low activity at low temperatures, on the basis of the above insulation protection and filling of thermal insulation materials, Xiaomi SU7 is also equipped with dual-mode heat pump technology, in addition to meet the needs of the battery thermal management, in -15 ºC without the need to turn on an additional heater to maintain a certain cabin temperature, and even in the -20 ºC of the climate conditions can still be obtained from the cold air heat. The SU7 also features triple-heat-source heating technology, which realizes up to 18 kW of battery heating power to extend low-temperature range and shorten low-temperature charging time.
Integration die casting technology compared to traditional punching and pressing welding assembly has less parts, low cost, high efficiency, as well as in the precision, safety and lightweight advantages, is the future of automobile manufacturing a big trend. However, integrated die casting in material, large mold integration, die casting strength and other aspects there are certain technical difficulties, especially pile die casting strength requirements are very high, so we see have integrated die casting technology of each brand die casting machine tonnage are very large. Tesla shanghai factory and the United States factory used 6000t and 9000t die casting machine, Zeekr factory for 7200t, Xpeng has the world's only one 12000t integrated die casting machine, and plans to expand a 16000t die casting machine in the future in order to manufacture larger die castings.
In contrast, millet used two 9100t die casting machine tonnage is not really big, at present mainly through the integrated die casting manufacturing part for the SU7 head triangle beam and 72 in 1 rear floor. Compared with the traditional stamping + welding process, the one-piece die-cast rear floor can reduce the weight by 17% and 840 weld joints, and the die-cast parts can also help to reduce the noise of the cabin by about 2dB. The die-casting material used to make the rear floor is developed by Xiaomi and is officially called "Xiaomi Titan Alloy", which is an alloy material consisting of more than 10 elements including aluminum silicide, rare earths, and zirconium, of which the aluminum content accounts for about 30%.
The suspension structure is a combination of front double-wishbone + rear multi-link, and of course, more importantly, Xiaomi's intelligent chassis technology, which includes CDC variable damping dampers and air springs, with adjustable soft and hard heights. At the same time, combined with the Bosch DPB brake controller and ESP 10.0 body stabilization system, as well as the full stack of self-developed chassis control algorithms, can realize the following three adaptive functions:
1. Road surface adaptive: the body stabilization function similar to a magic carpet can be predicted 5-150m in advance, 500 times per second motor torque control + 1000 times per second CDC damping adjustment to reduce the impact of bumps and improve smoothness.
2. Curve Adaptive: 500 times per second motor torque control, 1000 times per second CDC damping adjustment, optimize acceleration and deceleration tilt/nod amplitude, inhibit roll and improve body responsiveness when cornering.
3. Aerodynamic Adaptive: automatically adjusts the height of the rear wing and air spring, and actively controls the front grille opening.
The SU7 with fast start & top speed naturally needs to have excellent braking ability in order to give users sufficient confidence. Its Max version is equipped with Brembo four-piston braking system, which makes the shortest distance from 100km/h to braking stop only 33.3 meters, which is 6.6% shorter than the braking distance of the rear-drive version (35.5m) that does not have a high-performance braking system.
In terms of safety, the entire car adopts an armored cage-type steel-aluminum hybrid body, with the proportion of high-strength steel and aluminum alloy reaching 90.1%, and the torsional stiffness reaching 51,000N-m/deg, which is higher than that of the super sports car Bugatti Veyron (50,000N-m/deg). The battery crossbeam and door sill beam are made of 2000MPa ultra-high-strength steel and ultra-wide multi-chamber extruded aluminum alloy respectively, which can withstand lateral impacts of up to 820kN.
Xiaomi Pilot Xiaomi intelligent driving covers three major parts:
1. full-stack self-research smart driving algorithms
2. single NVIDIA DRIVE Orin for the rear-drive version and dual chips for the Max version (total computing power of 508 TOPS)
3. (Max version) 128 threads + 1,530,000 points cloud / second integrated LiDAR (rear-drive version without LiDAR)
Based on ultra-high resolution occupancy network technology, the system's recognition accuracy for shaped obstacles is as low as 0.1m (0.32m for Tesla), and is more accurate for small objects such as highway tollbooth stop bars and temporarily set up movable traffic lights. In addition, it can also recognize the water mist raised by the front vehicle in rainy and snowy weather, reducing the probability of misrecognition.
The overall recognition accuracy of the entire Smart Driving System is high, but in different environments the recognition accuracy will be adjusted according to demand. Parking state of the system's minimum recognition accuracy and pixel grid size of 0.05m, can recognize the floor locks and other small-sized objects, the scene demonstration video shows that the width of 1963mm SU7 can rely on the auto-parking function to autonomously park into the minimum 2.05m wide lifting space, parked automatically close the rear-view mirrors. Function, the system supports away from people to automatically find a parking space and parking, and even further can complete automatically through the gate, automatic cross multi-level, automatic will let the car, call when no one to take over the car and other "difficult" action.
In the city and highway roads to enable the smart driving function, the widest recognition range of 160m in the city, in the two-way 10 lanes of the wide avenue can also turn autonomously. Higher speeds on the highway, the need to detect the road ahead of the front of the car farther, high-speed state of the front of the car front field of vision increased to 250m, the pixel grid size of 0.2m.
