After a thousand years of trading, start a million barrels of oil

Chapter 126 Hard Gang Te Spicy

Jiang Fan thought about Wei Qiang's problem, and the situation was indeed more urgent than that of high-end CNC machine tools, which was equivalent to a race against time.

It's a pity that the young people only gave 60% of the technical information at that time. If it can be completed like a machine tool and there are prototypes, just read it, and there will be no so much hesitation and entanglement.

Regarding Professor Wei's first question, Jiang Fan didn't have a good plan. Research and development of this kind of thing needs to be overcome slowly one by one, and there is no rush.

But for the second question that Professor Wei said, he has some ideas. The other party's solution is not to break through the idea of ​​battery cells, but to start with the battery management system, through a more reasonable structure, more effective scheduling, and improve The group performance of the battery can achieve the purpose of improving battery life.

We can also learn from this idea.

Jiang Fan thought of this and looked at Wei Qiang: "Professor Wei, I understand that we also have a blade battery, can you tell me the specific situation?"

Wei Qiang nodded: "Biadi's blade battery was released on March 2020, 3, and it is actually similar to the 29. It is not an improvement on the single battery, but a structural innovation.

This battery uses lithium iron phosphate technology and will be first installed on the "Han" model.

Through structural innovation, "modules" can be skipped when grouping, which greatly improves the volume utilization rate, and finally achieves the design goal of loading more batteries in the same space.

Compared with traditional battery packs, the volume utilization rate of "blade batteries" has increased by more than 50%, which means that the cruising range can be increased by more than 50%, reaching the same level as high-energy-density ternary lithium batteries.

It's just that the final effect of this technology is still much inferior to that of the latest 4680 to be launched by Masigram. "

After Wei Qiang finished speaking, he showed some specific technical details including materials to Jiang Fan and explained them.

Jiang Fan nodded, and continued: "I haven't thought of a good way to quickly break through the all-solid-state battery.

However, regarding the launch of a new car with a size of four grams next month, it is not too late to compete with him.

You think, if we have a battery management system that is more efficient than the Y[-]G, combined with our own blade battery module, we can create a new car with better performance and longer battery life than the one he is about to release. battery system? "

"This" the professors were lost in thought.

"You mean the management system mentioned in the technical information given?" Wei Qiang realized that there was indeed a piece of content that mentioned a better battery management system.

"Not bad." Jiang Fan said.

"We have actually thought about this before, it is not compatible with our blade battery system." After Wei Qiang finished speaking, all the professors also nodded in agreement.

Jiang Fan smiled, you said that based on the knowledge system in 2022, they are incompatible, can I tell you that you have found a solution to make them organically combined around 2030?

Jiang Fan didn't say much, got up and went to the whiteboard next to him, picked up a marker pen and started drawing on the whiteboard.

"As long as we make some adjustments to the blade structure."

As soon as Jiang Fan explained, the entire whiteboard was basically filled with drawings.

A group of experts and professors listened intently, and many technical details and ideas constantly broke their thinking inertia.

After listening to everything, a group of people only looked at each other and shook their heads and smiled in disbelief. It's too awesome. How did you come up with this kind of thinking.

When Jiang Fan solved the negative electrode material proposed by the researcher just now, Wei Qiang had already admired Jiang Fan, but he was still lucky. Maybe it was a blind cat meeting a dead mouse.

But when Jiang Fan just finished talking about the organic fit of the entire management system and the module system, he completely admired Jiang Fan.

It may be possible to solve a problem, but it is impossible to rely on luck to complete the organic integration of a system. It can only be hard power, and they are really good.

Not only the technical strength, but also the strategic vision of this person. He is not like many scholars who like to focus on the knowledge itself and ignore the combination with strategy.

As soon as people listened to my speech, they immediately realized that they had to break it down and compete segment by segment. They had to win the technology and at the same time not lose the market, which is amazing.

He now admires this friend's student, the director of the Joint Research Institute, from the bottom of his heart.

Jiang Fan asked everyone's opinion on what he just said, and seeing that everyone had no opinion, he added:
"In my opinion, this matter can be divided into two parts, and some people are selected to form a project team for a short-term special purpose to overcome the integration of blade battery modules and battery management systems.

Others continue to interpret and promote the research and development of solid-state batteries without delaying the progress. What do you think? "

Everyone nodded. This allocation is very reasonable. Director Jiang should often do this kind of overall planning and allocation work. It can be seen that he is very skilled in his movements and voice.

"Okay, if that's all right, the specific project team members and other personnel arrangements will be determined by Professor Wei, and the meeting will be adjourned." Jiang Fan directly left the job to Wei Qiang, acting as the shopkeeper.

After finishing the matter of the joint research institute, Jiang Fan doesn't need to go there every day, just go to a regular meeting to listen to the situation report, solve some bottleneck problems and set the follow-up direction at the same time.

Xiao Zhou is a migrant worker. He works alone in a big city. His income is not bad, but buying a house in a big city is still unrealistic.

His parents, wife and children are all in his hometown, and his working city is nearly 500 kilometers away from his hometown. He has to go home every week or two.

Although being able to see his parents, wife and children made him very happy, what bothered him was that the fuel cost was too high. The gas cost of hundreds of dollars would be gone in one round trip, especially with the recent rise in fuel prices, which made the cost of refueling even higher.

Therefore, Xiao Zhou especially hopes to replace his gasoline car with an electric car. Electric car charging only costs about one-fifth to one-tenth of the price of a gasoline car, especially for his heavy usage, so he can save money every month. The money is not a star and a half.

But the reason why I have not dared to start is that the various disadvantages of electric vehicles, the cruising range is too short, and the number and distribution of charging piles are far from enough.

If you run out of power halfway along the highway, you can’t find a charging pile, and you have to wait a lot when you find it. After all, charging is not as fast as refueling, and sometimes you can encounter broken ones, which is too much trouble.

And not long ago, he saw news on the news that Miguo Teshala is going to release a new car equipped with a 4680 power battery in the near future. It is said that the cruising range can be about 800 kilometers, which has already met his expectations.

Because even if it is not fully charged or the battery is locked for some reason, there can still be five or six hundred kilometers available, and a single trip is usually enough.

So he plans to go to the 4S shop to have a look after it is released, and if it is really good, he will sell the current gasoline truck and buy one.

He has also paid attention to some domestic brands. It’s not that he doesn’t want to support domestic brands. Although the performance indicators are not bad, after this round of 800-kilometer battery life, the price is said to have not increased much. In comparison, it must be someone else who is more cost-effective high.

Xiao Zhou decided that unless a comparable car can be produced in China, there is no need to hesitate too much, just buy it.

Jiang Fan was preparing to go to the research institute that day, when he received a call from Zhang Feng, saying that the higher-ups had decided to retain the title of honorary director, and at the same time officially appoint him as the official director of the joint research institute, enjoying all the rights and treatment of the official director .

Jiang Fan didn't know why there was such a change, but he didn't care, anyway, he was working as a formal director anyway.

Professor Wei and the others also received the appointment of Jiang Fan at the same time. If it had been postponed, they would have protested. Isn't it a joke to let a young child lead their group of experts and professors who are all industry elites?

But now, no one has any objections. In just one or two weeks, they have cultivated a habit. Whenever they encounter problems that cannot be solved, the first thought that pops up in their minds is to find Director Jiang.

And if you find it, you will definitely be able to solve it, so since Jiang Fan came, no one in the institute dared to say that the progress was delayed because of bottlenecks, because the logic is not valid. The bottleneck problem is said.

After Jiang Fan arrived at the research institute, he directly held a meeting to discuss the recent progress.

Knowing that the fusion technology of battery management and blade modules is close to completion, I am quite satisfied with the progress.

It’s just that the progress of the analysis and development of another module cell is not fast at present, and Jiang Fan can also understand that there are too many contents to be digested and developed, and many details need to be broken through.

Take it slow, it's not that urgent right now.

There is still more than half a month left before the launch of the new car, and the battery has been made. The following is how to deal with the problem in marketing.

Jiang Fan had already considered this issue, so he also invited Biyadi's sales director to come to this meeting in advance.

The person in charge of sales expressed his opinion: "We already have a batch of cars ordered by customers in production. We can negotiate with these customers to upgrade the battery system of their cars to a new battery system with stronger power in this batch. I believe They must be receptive.

In this way, we can accumulate word-of-mouth and collect feedback faster for optimization and improvement. After waiting for three or four months, we can stagger the popularity of the opponent's release, and our technology can be further improved. It will be more appropriate to release it at that time. "

Jiang Fan thought for a while, and it made sense, but he was not satisfied, and said: "This method is a bit of a way to avoid the edge, it's not impossible, but it's unnecessary.

Our current technology is already very good, and my idea is to have a head-to-head encounter with Teshala.

It is definitely too late to release it on the same day as him, but it can’t be too late. It takes about a month for the whole vehicle test, assembly line, and pre-production work, so we will release it one month later, which is equivalent to half a month later than him.

At that time, the new battery will be installed on the new car and released as a separate model. After half a month, it is still within a big cycle. If it is publicized in advance, buyers will still put the two cars together for comparison and choose, and they can still start. What do you think of the effect of a frontal touch? "
