AutoBeta(AutoBeta.net)07/21 Report--

A few days ago, some netizens revealed that a millet SU7 chassis in a residential area was emitting white smoke. Xiaomi Automobile officially released "Xiaomi SU7 answers netizens' questions (episode 45)" on July 18, responding to the above incident.

Xiaomi official said that the day before yesterday, Xiaomi received the driver of the vehicle into the line, feedback that the vehicle had a short-term local smoke phenomenon after the collision. The service staff of Xiaomi car store rushed to the scene as soon as possible. after communication with users and on-site inspection, the situation was confirmed as follows:

1. The chassis of the vehicle has serious damage caused by obvious external force, but the battery package has only a short period of pressure relief and exhaust, and there is no heat spread and no fire. At the same time, the background data networking function was actively turned off at the time of the accident.

2. Extreme external force collision is suspected to have occurred at the bottom of the battery of the accident vehicle. According to the analysis of the on-site situation, it is speculated that the ultimate trigger of the extreme operating conditions (it is not possible to confirm whether the chassis has been bumped before) is a loose marble concrete floor tile (300*300*20mm), which tilts one side after the tire is rolled, violently hits the bottom of the battery pack at a sharp intrusive angle, and causes it to tear (the maximum opening exceeds 350mm). Finally, the bottom of the battery pack is seriously sunken (the maximum depth is more than 30mm), and the internal cell is damaged and exposed, and the amount of deformation is about 14.3mm.

3. The development of Xiaomi CTB battery pack is designed according to the highest safety standards, and carries out comprehensive and stringent tests for the collision safety at the bottom of the battery, such as placing the solid hemisphere with a diameter of 150mm on the ground, and then scraping the bottom at the speed of 30km/h, and the deformation of the cell is only 1mm. And even in response to the industry's most stringent bottom impact test, the battery deformation is only 5.4mm. In this accident, the deformation of the cell exceeds that of 14mm, which is 2.6 times that of the most stringent test, which is an extreme condition. However, due to a series of protection measures of Xiaomi SU7 battery pack, no more cells caught fire due to heat spread, and only temporary pressure relief and exhaust occurred.

At present, Xiaomi Automobile is assisting users to properly handle follow-up matters. At the same time, Xiaomi stressed that the above events can only be regarded as extremely accidental circumstances, due to extreme external forces caused by a very small probability of extreme operating conditions. Without knowing the real situation, some of the reports have been completely untrue in terms of "spontaneous combustion" and "fire". I hope you will not believe the rumors and do not spread the rumors.

It is understood that Xiaomi SU7 is a blockbuster model built by Xiaomi Automobile in three years, and it is also the first model of Xiaomi Automobile. It is based on Xiaomi Modena platform architecture, positioning C-class high-performance eco-tech cars, which went on sale on March 28th. The current price range is 21.59-299900 yuan. Power provides dual-motor version and single-motor version of the model choice.

As Xiaomi Group's first masterpiece to enter the new energy vehicle market, Xiaomi SU7 has attracted the attention of many consumers since its launch. Retail data show that since the launch of Xiaomi SU7, Xiaomi SU7 delivered a total of 30, 000 vehicles by the end of June, of which April-June sales were 7100, 8600 and 14300 respectively, showing a gradual growth trend. As a new car just on the market, Xiaomi SU7 has delivered more than 10,000 cars a month, which has indeed created a miracle in China's auto market, which to a certain extent reflects consumers' recognition of Xiaomi cars.

According to the plan, Xiaomi will deliver at least 100000 cars this year and sprint 120000. Calculated on the basis of 100000 vehicles, it means that Xiaomi needs to complete the delivery of 70, 000 vehicles in the next seven months, with an average monthly sales of 10, 000 vehicles, while if it is calculated on the basis of 120000 vehicles, the average monthly sales volume will reach about 12900 vehicles, which is still under great pressure. However, Xiaomi pointed out in the above article that the Xiaomi car factory experienced a production line maintenance tuning in July, but it will not affect the achievement of the set target of delivering more than 10,000 units a month.

On July 12, in the 385th batch of "Road Motor vehicle production Enterprise and Product announcement" new product announcement disclosed on the official website of the Ministry of Industry and Information Technology, four "Xiaomi brand" pure electric cars appeared. The new tail bid of Xiaomi SU7 was changed from "Beijing Xiaomi" to "Xiaomi", and the name of Xiaomi SU7 production enterprise was also changed to "Xiaomi Automobile Technology Co., Ltd." This also means that Xiaomi Automobile has officially acquired the qualification to build independent cars.

As for whether Xiaomi will launch other new cars in the future, it is not clear and will not be known until further official announcements. It should be noted that for the online popularity of the "Xiaomi SU8" model, Xiaomi car said: "it is not true, Xiaomi car does not have such a car line, model planning."
