Technological Hegemony

Late at night, Baoshan base.

"Mr. Luo has been in the office all day?"

"No, then when I gave him lunch, I saw that he was keeping his eyes closed and his eyes frowned, as if thinking about it. When I sent him dinner, he saw that he quickly wrote the formula in his notebook. . "

"Not easy, after all, after the hardware department has got the battery, the next thing is the car project."

"real or fake?"

"Of course it's true. You haven't seen Luo always used to point to the project department below. Now he has been playing in person. He keeps writing complex formulas that I can't understand, and has drawn a lot of circuit design diagrams."

Several employees of the administrative department were whispering, talking about Luo Jia's changes in recent days.

In Xingchen Technology, the administrative department is equivalent to the function of the logistics headquarters.

Luo Jia wanted something to go to the administrative department, wanted to print some documents, send a few courier services, or went to the administrative department, so they knew the recent changes in Luo Jia.

In the past, Luo Jia was like an inspector. I went to this project team to take a look today, and led everyone to think about how to overcome difficult ideas. Tomorrow, I will go to other project teams to hear their work progress.

When he encountered difficulties, he called a brainstorming group to meet.

But now, Luo Jia kept herself in the office and couldn't come out all day, as if she was trying her best to solve any problems.

Unlike the way other people work, Luo Jia needs to be absolutely quiet, because when he is designing a plan, he still has to query the data, and the data is in his brain.

This is a kind of meaning of natural exchange. On the one hand, it extracts useful parts from massive data, on the other hand, it also needs to integrate these technical data into a feasible solution.

What he is currently trying to solve is the problem of lithium battery back-end consistency, that is, a large-scale electrical control system.

This thing is one of the lifeblood of electric cars, and even more important than battery packs.

In the past few days, Luo Jia worked at least sixteen hours a day. In addition to contemplating in the office, she was sleeping in a meditation center. The only entertainment was to call parents who were far away in Russia and ask them about their travel.

Despite Luo Jiaqian's orders, Comrade Luo Ning was in trouble.

On the second day of Vladivostok, Comrade Luo Ning had a fight with the Russians.

When he learned that the Russian name of Vladivostok was Vladivostok, meaning to conquer the East, and a sculpture was set up beside the sea, pointing to the land of China, he looked very upset and stared at the local area. Tour guide eyes.

The local tour guide is a Russian. He will talk. He asked Comrade Luo Ning, what did you do to me?

Comrade Luo Ning said that Vladivostok, Hailan Pao, and Baikal were all robbing us of China. From 1926 to 1937, you mass excluded Chinese people and killed nearly 200,000 Chinese. This account will be calculated sooner or later!

The Russian tour guide was anxious on the spot, and the two of them worked directly without saying a word.

Comrade Luo Ning was punched in the face. The Russian tour guide was opened with a bottle of wine by Comrade Luo Ning. The fight between the two men was fierce, and Luo Jia's mother was frightened.

Fortunately, in addition to arranging ground pick-ups, the travel agency also arranged a full **** and a driver, and they quickly urged people away.

It is said to be so unpleasant, Comrade Luo Ning hurried home.

In the end, Comrade Luo Ning said that he would leave nothing, and since this is our land, why did he let me go?

No way, the travel agency had to send Comrade Luo Ning and Luo Jia's mother to Lake Baikal overnight, fearing that the local snake tour guide would take the opportunity to retaliate, and urgently arranged two bodyguards with large waists among Comrade Luo Ning.

When Luo Jia and Luo Ning talked on the phone, he wasn't finished yet, and he thought he would meet again next time. The Russian must look good.

Anyway, Comrade Luo Ning's trip to Russia began in this vigorous atmosphere.

Luo Jia can't help Dad. He has an upright personality and jealousy throughout his life, and has repeatedly told him and his mother to pay attention to safety.

Shenzhen City, BYD Group.

It is widely rumored that the major battery factories and Luo Jia have fallen out. In fact, that is just an illusion.

After getting the diaphragm and machine of Xingchen Technology, major battery factories have been working overtime to make the first batch of products.

On May 5th, the first batch of 18650 high-capacity batteries officially went offline, and then they performed a consistency test on this batch of products.

What is consistency check?

It is to detect whether all batteries have the same performance, and the detection process is extremely complicated, and hundreds of tests are required.

From physical characteristics to chemical characteristics, from internal resistance to voltage, from the amount of electrolyte injection to the width and density of the pole pieces, from the charge curve to the discharge curve.

All in all, this is a super complicated project.

The purpose of the conformance test is to ensure that all batteries are exactly the same.

After 10,000 batteries are fully charged and discharged one hundred times, the capacity drops by 3.7 percent, so all of them must be 3.7.

If there is a decrease of 3.6, and there is a decrease of 3.8, there will be a big problem in the end.

This is the rigorous standard for power lithium batteries. All lithium batteries, whether 10,000 or 100 million, must be all consistent, and the error rate must be strictly controlled.

After all, power batteries are used for electric vehicles. An electric vehicle can be 7,000 to 8,000, or even tens of thousands of batteries. You must ensure that each battery will not cause problems.

People who do not understand this industry will always feel that there are only a few batteries. What is the difficulty?

However, in fact, the lithium battery industry is really difficult and belongs to the absolute top technology.

So far in the world, there is no manufacturer that can completely solve the battery consistency problem, and even Panasonic, the world's first, cannot do it.

Tesla, which uses Panasonic's top battery, cannot be said to be unadvanced, and the price is very high.

But even Tesla can spontaneously ignite.

The fundamental reason is that the front-end and back-end electrical controls are not perfect. After using for a period of time, individual batteries age too quickly, leading to catastrophic consequences.

BYD's engineering team did repeated tests on the first batch of offline batteries, and then put the test report on the desk of boss Wang.

After looking at Mr. Wang, he stayed straight!

According to the test report, the total number of the first batch of batteries is 100,000, and all performance is completely the same!

Mr. Wang stunned, took off his glasses, quickly wiped them with the glasses cloth, and then picked up the report again, starting from the first page.

After a long time, he put the report on the table, took a deep breath, and said to the chief engineer Liao Anhai, who was waiting beside him, "One hundred thousand batteries, all of them are the same, am I correct?"

Liao Anhai nodded forcefully. "No, it is 100% consistent. We have never seen this before."

Boom ~

President Wang's head exploded directly. When Luo Jia sold the machine and diaphragm to BYD that day, he did not mention consistency.

Mr. Wang felt that everyone's level should be similar. There are so many seven or eight substandard products in 10,000, which is also allowed by the industry, so I didn't ask too much.

At this moment, he discovered that the defective rate of the battery made by Xingchen Technology's machine was zero. No defective products at all!

Liao Anhai Shen Sheng said, "General Manager Wang, this time the problem is big. People who are doing this are very clear. The so-called defective products are like students who have passed the 50th grade test. Fifty-fifth, and sixty-fifth, and eighty-fifth, anyway, as long as it is higher than sixty, we are considered to be passing. "

"But the products made by Xingchen Technology are all 100%! This is no longer an exam, but a machine answer! Our engineering department thinks that the test results are totally incredible. I really don't know how they did it!"

"Hell!"

President Wang rarely swears a swear word. He is a master of the nonferrous metal research institute and a senior intellectual among businessmen, so he is too aware of the terrible technology of Xingchen Technology.

Lithium battery with perfect consistency?

what is happening!

To be honest, he is a bit scared now, and even Panasonic has not been able to overcome the problem. Star Technology solved it in one fell swoop?

I knew this was the result. When he was in Changzhou that day, President Wang wouldn't cheer and applaud. He should worship and worship!

"Book a ticket now!"

Mr. Wang suddenly got up from his seat, flushed, and said to the secretary, "I'm going to Shanghai."

The manufacturers of diaphragms and machines that have already bought from Xingchen Technology, their bosses came to Hudu by accident, because they were all surprised by the test results.

I thought Xingchen Technology solved the battery density problem. Whoever thought, they also solved the consistency, the most terrible problem!

From BYD's President Wang to Ningde's Huang, these lithium battery bosses entered Luo Jia's office before and after, with an eager look.

After listening to their words, Luo Jia smiled and scratched her head. "I seem to have said this, right?"

President Wang waved his hands quickly, "I didn't say, I remember very well, I knew you had solved the problem of consistency, shall we come over overnight?"

Mr. Huang of the Ningde era also said, "Yes, we all thought that you had a battery technology one-sixth the density of Panasonic. Now it seems that your technology is not only powerful, it is simply God!"

Luo Jia recalled, "You remembered it wrong, I said that day that Xingchen Technology has completely opened up the lithium battery technology chain, and this technology chain obviously includes consistency issues."

Everyone was stunned, and the technical revolution with such an important feeling was brought by Luo Jia in one stroke, without focusing on it!

What is this saying?

We must know that for the lithium battery industry, the consistency problem is more than the density problem.

After all, a lower density will not kill people, and the consistency problem will cause the vehicle to burn down or even explode, which is fatal.

"We solved it with a mold temperature machine." Luo Jia said, "I am not convenient to tell you the specific technical details, but our mold temperature machine is based on the traditional four major technical indicators, and three new indicators have been added."

"In short, I sell you not only the machine, but a complete set of solutions. Imagine that if you don't use our mold temperature machine and change to other manufacturers' machines, you don't need to find me."

So this is ah!

Everyone suddenly realized ~ www.wuxiahere.com ~ The mold temperature machine is a machine used in the coating process of lithium batteries, in order to keep the raw materials uniform and highly consistent.

Luo Jia did not mention the mold temperature machine to the outside world, but secretly sold the mold temperature machine to BYD.

Now think about it, there is a reason that Luo Jia does not mention the mold temperature machine.

It turns out that the mold temperature machine manufactured by Xingchen Technology is completely different from the past products, and major technical upgrades have been made!

Just when everyone was ecstatic, they all said that they would immediately expand production. When the lithium battery industry was doing a big job, Enron suddenly rushed in.

He didn't even have time to say hello to Luo Jia, turned on the TV directly, and adjusted to the news channel.

"exploded!"

"Ten minutes ago, South Korea really exploded!" Enron shouted excitedly.
