In fact, it is said that it is bright on the surface, but Li Fanyu's idea is quite simple.

"In the past, there was no way, and if there was nothing, of course we had to chase and fight. Now that the master has a status in the Chinese market, of course he has to ride them to fight!" Li Fanyu, who returned to Tiancheng and intervened in the I8 project, told the engineers.

During this period of time, several assembly parts of the I8 have begun to see the context.

According to the previous R&D plan, Xu Fufang has led the team to roughly complete the chassis part, and further optimized the overall distribution and battery, electronic control, and body weight ratio according to the cost control required by Li Fanyu and some other needs.

The power aspect should have been completed by Liu Qing's team, but because the R&D center already has a ready-made in-wheel motor. Therefore, Liu Qing's team had to carry out a temporary split, and a part of it was combined with Xu Miao and others, who had previously started the research and development of "gyro" hub motors. Because of Li Fanyu's structural design with design expertise, a set of finished products has been manufactured and is now being tested.

According to the original R&D goal of Zhongzhong, the weight of the I8 vehicle needs to be controlled within 2000KG. The acceleration time should be at least within 0-100KM/h6.5S. Because it is a sports car, the loading performance requirements are low, and it is considered to be a pass within 800KG. IN THIS WAY, THE MAXIMUM ALLOWABLE WEIGHT IS 2800KG.

The battery is ready-made, according to the body layout standard, the I8 pure electric interior can be loaded with a maximum length of 0.8m, a width of 1.2m, and a maximum volume of 0.56 cubic meters of battery space. However, this space needs to take into account the placement of radiators, so according to the design of Xu Compound, it is initially planned to be equipped with two sets of super dissolved metal battery packs.

According to the current power of the hub motor, the I8 can have a maximum travel of 320KM under the condition that the battery pack is fully charged and the body is fully loaded.

With such a battery capacity, under the standard electric pile of 400V and 16A, the charging time can be shortened to 15 minutes for 60% fast charging and 60 minutes for 0-100% charging. Under the condition of 200V10A household electricity, the home power conversion charger designed by Wang Yu's team for super dissolved metal battery packs can also reach a full state of power in 3 hours.

This is the basic performance.

On this basis, in order to implement the principles of "green environmental protection, ease of use innovation and customer economy" formulated by the team. In terms of the electronic control system, the R&D team has done a lot of tricks.

According to the Group's marketing department's survey of the users of pure electric models in the market, especially the two models of TSL, 86% of the users who choose pure electric models are users in first-tier cities with license plates restricted in Beijing, Shanghai, Guangzhou, Shenzhen and other cities, and it is difficult to obtain the road through lottery bidding, and there is a green channel policy for new energy vehicle license plates.

As we all know, these four international metropolises with a population of more than 10 million are the hardest hit areas by traffic congestion.

In view of such characteristics, as the same I8 as Pally, the electronic control R&D team has carried out a series of model innovations;

For example, to cope with traffic congestion, a low-power mode similar to the automatic sleep and wake-up of mobile phones has been added. An electronic control scheme for energy-saving mode at low speeds and so on to reduce power consumption and improve battery life.

In addition, according to market research reports, about 54% of the users of pure electric vehicles are female users aged 22-32.

In order to win the "heart" of this type of user, the R&D team has also further optimized the control mode of I8;

In addition to integrating the pattern recognition technology of Baiwei Interactive Entertainment previously used in high-end models such as A4,6,8 mini into the I8, adding basic intelligent control functions such as automatic parking and positioning. It also relies on the power layout scheme driven by 4x4 in-wheel motors, and sets up female users who are friendly to "stream of consciousness driving" such as greatly improving the turning angle in a small space and even making a U-turn on the spot.

Li Fanyu, who returned to Tiancheng, was quite satisfied after seeing the progress of the R&D team and the results achieved at this stage.

In a small conference room in the R&D center.

Li Fanyu put down the information about the current R&D progress in his hand, and smiled at the three Xueba sitting opposite: "It's good, the current progress and results are really beyond my expectations." ”

Hearing Li Fanyu's praise, Liu Qing raised his nostrils, "That's, you don't look at who is in charge of this project." Our brothers have been separated from the group's business for a long time, and this reunion will of course explode into the entire small universe. ”

Xu Fufang said that "in fact, the main thing is that the meaning of the I8 car is different. Thinking about the time when I was in Germany, the five of us students who had not yet left the school with an unknown reputation were treated with cold eyes and treatment when they came up with this design, and I was holding back a breath of anger in my heart. ”

Wang Yu obviously agrees with this statement, "That's right." To tell the truth, the defendant was plagiarized in Munich, and the Saifang so easily believed the statement of the people at Dongda, and I will never forget the matter of taking our I8 down. To this day, I can still remember the kind of competition team at that time, that kind of ...... Although we can't find too conclusive evidence, based on the ability of your Chinese students, it is surmised that you have plagiarized your attitude. After the development of Zhengxin, I would like to suggest to you several times to reshape I8, our original dream, and put it on the market to prove us again. Now that I finally have a chance, of course I feel like I'm full of energy!"

"Oh, it's like yesterday when you think about it. After Wang Yu and Xu Fufang said this, Li Fanyu's mind came back to the situation in Munich.

Although only three years have passed, too many things have happened in the past three years, and now thinking about it makes Li Fanyu feel like a world away, as if it only happened yesterday.

In three years, I have gone from a poor student with nothing to today. Zhengxin has also grown from scratch until it has become such a behemoth with fixed assets of more than 150 billion yuan and total assets of more than 200 billion yuan.

Among the five people who went to Germany together at the beginning, and the people involved. Professor Zhang has now become a big man in the field of education and the automotive industry, in addition to presiding over the training of senior technicians of Zhengxin, but also leading the research and development center of Zhengxin. Basically, every time Tiancheng University of Technology communicates with other universities at home and abroad, it has to invite him to the town.

Sanxueba has also grown from a technical nerd to a senior engineer who can lead one side alone.

Cheng Ke has grown from a second-year sick girl to a person who can lead the R&D team and the project internally, and can lead the team to kill the Quartet, and he is very good at fighting battle royale and eating chicken...... A girl with a second illness.

Yourself, not to mention.

His eyes were foggy for a moment before he came to his senses and smiled at the three of them, "Okay, let's work harder." Now that the EV market has changed, the I8 should be completed as soon as possible. You go and explain to the team in a moment and ask them to speed things up. But it's not bad to be in a hurry for a while, so don't work overtime tonight. Let's go out and get together, and tomorrow, we'll start chasing the progress!"

"Gotcha!" Hearing Li Fanyu say that he wanted to treat him, the three scholars let out a burst of cheers.
