Technological Supremacy Chapter 124: Comrade Luo Ning exploded, and 3 stars also exploded!
Late at night, Baoshan Base.
"Boss Luo has been in the office all day, right?"
"That's right, when I brought him lunch, I saw him closing his eyes and resting his mind, with a frown, as if he was thinking. When I brought him dinner, I saw him scribbling in his notebook The writing formula."
"It's not easy, after all, after the hardware department has finished the battery, the next step is the car project."
"Really or not?"
"Of course it's true. Didn't you see that Mr. Luo used to point out most of the project departments below, but now he has come to the field in person, writing complex formulas that I can't understand, and drawing a lot of circuit design diagrams What about."
Several employees of the administration department were discussing in low voices, talking about Luo Jia's changes in recent days.
In Star Technology, the administrative department is equivalent to the function of the logistics headquarters.
Luo Jia wanted something to eat and went to the administration department, wanted to print some documents, send some couriers, or go to the administration department, so they knew Luo Jia's recent changes very well.
In the past, Luo Jia was like an inspector. Today he went to this project team to have a look and lead everyone to think of ideas on how to overcome difficulties. Tomorrow, he went to other project teams to hear their work progress.
When he encountered difficulties, he called a meeting of the brainstorming group.
But now, Luo Jia locked herself in the office and didn't come out all day, as if she was trying her best to solve some problem.
Different from the way other people work, Luo Jia needs to be absolutely quiet, because when he is designing a plan, he has to constantly search for information, and the information is in his brain.
This is a bit of a communication between heaven and man. On the one hand, it is to extract useful parts from massive data, and on the other hand, it is necessary to integrate these technical data into a feasible solution.
What he is currently trying to solve is the back-end consistency of lithium batteries, that is, large-scale electronic control systems.
This thing is one of the lifeblood of electric vehicles, even more important than the battery pack.
In the past few days, Luo Jia worked at least 16 hours a day. Apart from thinking in the office, he slept in the meditation center. The only entertainment was to call his parents in Russia and ask them about their travel Condition.
Despite Luo Jia's exhortations, something happened to Comrade Luo Ning.
On the second day after arriving in Vladivostok, Comrade Ronin had a fight with the Russians.
When he learned that the Russian name of Vladivostok is Vladivostok, which means to conquer the East, and that there was a sculpture on the seashore pointing to the land of China, he was very unhappy and ruthless. He glared at the local tour guide.
The ground guide is Russian and can speak. He asked Comrade Luo Ning, what are you looking at me for?
Comrade Luo Ning said, Vladivostok, Hailanpao, and Lake Baikal all robbed us of China. From 1926 to 1937, you massacred Chinese and killed nearly 200,000 Chinese. To count!
The Russian tour guide was in a hurry on the spot, and the two of them did not say a word, and went straight to work together.
Comrade Luo Ning was punched in the face, and the Russian tour guide was opened by Comrade Luo Ning with a wine bottle.
Fortunately, in addition to arranging the ground pick-up, the travel agency also arranged a full **** and a driver, and they quickly persuaded the person to leave.
It is supposed to be so unpleasant, Comrade Luo Ning should hurry home.
As a result, Comrade Luo Ning didn't say anything and said that this is our land, why let me go?
No way, the travel agency had no choice but to send Comrade Luo Ning and Luo Jia’s mother to Lake Baikal overnight, fearing that the local snake tour guide would find an opportunity to retaliate, and urgently arranged two bodyguards with big waists among Comrade Luo Ning’s entourage.
When Luo Jia was talking on the phone with Comrade Luo Ning, he was still in the middle of the conversation, yelling that we would meet again next time, and that the Russian must look good.
Anyway, Comrade Luo Ning's trip to Russia started in such a vigorous atmosphere.
Luo Jia can't do anything about his father. He has an upright personality all his life and hates evil, so he has to tell him and his mother to be careful
Shenzhen, BYD Group.
It is widely rumored that the major battery factories and Luo Jia have fallen out, but in fact that is just an illusion.
After receiving the diaphragm and machines from Star Technology, major battery factories have been working overtime to produce the first batch of products.
On May 5th, the first batch of 18650 high-capacity batteries officially rolled off the production line, and then they conducted a consistency test on this batch of products.
What is consistency detection?
It is to test whether all batteries have the same performance, and the testing process is extremely complicated, requiring hundreds of tests.
From physical characteristics to chemical characteristics, from internal resistance to voltage, from electrolyte injection amount to pole piece width and density, from charging curve to discharging curve.
All in all, this is a super complex project.
The purpose of the consistency test is to ensure that all batteries are exactly the same.
10,000 batteries, after being fully charged and discharged 100 times, the capacity drops by 3.7%, so it must all be 3.7%.
If there is a drop of 3.6 or 3.8, there will be a big problem in the end.
This is the harsh standard for power lithium batteries. All lithium batteries, no matter 10,000 or 100 million, must be consistent, and the error rate must be strictly controlled.
After all, power batteries are used for electric vehicles. There are usually seven to eight thousand or even tens of thousands of batteries in an electric vehicle. It is necessary to ensure that each battery will not go wrong.
People who don't know this industry will always think that it's just a battery, how difficult can it be?
However, in fact, the lithium battery industry is really difficult and belongs to the absolute top technology.
So far, no manufacturer in the world can completely solve the problem of battery consistency, even the world's number one Panasonic can't do it.
Tesla, which uses Panasonic's top battery, cannot be said to be advanced, and the price is also very high.
But even Tesla can spontaneously combust.
The fundamental reason is that the front and rear electronic controls are not perfect. After a period of use, some batteries age too quickly, which leads to catastrophic consequences.
BYD's engineering team repeatedly tested the first batch of off-line batteries, and then put the test report on the desk of the boss, Mr. Wang.
After watching it, Mr. Wang was stunned!
According to the test report, the total number of the first batch of batteries is 100,000, and all the performances are exactly the same!
Mr. Wang was taken aback for a moment, took off his glasses, quickly wiped them with a cloth for glasses, then picked up the report again, and started to read from the first page.
After a long time, he put the report on the table, took a deep breath, and said to Liao Anhai, the chief engineer who had been waiting beside him, "One hundred thousand batteries are all consistent, am I right?"
Liao Anhai nodded vigorously, "No, it's really 100% consistent. We have never seen such a situation before."
Boom~
Boss Wang's head exploded immediately. When Luo Jia sold the machine and diaphragm to BYD that day, he didn't mention the consistency.
Mr. Wang felt that everyone's level should be about the same. Among the 10,000 pieces, there are seven or eight substandard products, which are allowed by the industry, so he didn't ask too much.
At this moment, he discovered that the defective rate of the 100,000 batteries made by Xingchen Technology's machines is actually zero! There are no defective products at all!
Liao Anhai said in a deep voice, "Mr. Wang, this time there is a big problem. Those of us in this industry know very well that the so-called defective products are like students who have scored 50 points in the exam, but in such a large class, Not only those who got 50 points in the test, but also those who got 60 points and 80 points, anyway, as long as it is higher than 60 points, we will consider it a pass.”
"But the products made by Xingchen Technology are all 100%! This is no longer an exam, but a machine-answered question! Our engineering department thinks that the test results are completely incredible. I really don't know how they do it!"
"Damn it!"
President Wang seldom swears. He is a master of the Nonferrous Metal Research Institute and a senior intellectual among businessmen, so he is too aware of the terrifying technology of Xingchen Technology.
Have a lithium battery with perfect consistency?
What the **** is going on!
To be honest, he is a little scared now, the problem that even Panasonic failed to overcome, Star Technology actually solved it in one fell swoop?
If I had known this was the result, Mr. Wang would not have cheered and applauded when he was in Changzhou that day. He should have worshiped him!
"Book your flight now!"
President Wang stood up abruptly from his seat, his face flushed, and he said to the secretary, "I'm going to Shanghai."
The bosses of the manufacturers who bought diaphragms and machines from Xingchen Technology came to Shanghai by coincidence, because they were all shocked by the test results.
Thinking that Xingchen Technology has solved the problem of battery density, who would have thought that they also solved the most terrible problem of consistency!
From Mr. Wang of BYD to Mr. Huang of Ningde era, these lithium battery tycoons have entered Luo Jia's office one after another, looking anxious.
After listening to what they said, Luo Jia scratched his head with a smile, "I seem to have mentioned this question before?"
Mr. Wang quickly waved his hand, "I didn't say anything, I remember it very clearly, if I knew that you had even solved the consistency problem, why should we rush here overnight?"
President Huang of the Ningde era also said, "That's right, we all thought that day that you developed a battery technology with a density one-sixth higher than that of Panasonic. Now it seems that your technology is not only powerful, but also a god! "
Luo Jia recalled, "You remember wrongly. 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. The technological revolution, which is so important to emotions, was brought up by Luo Jia in one stroke, and it was not taken as a key point!
What is this called?
Know that for the lithium battery industry, the consistency problem exceeds the density problem.
After all, a lower density will not kill people, but consistency problems will cause vehicles to burn or even explode, which will kill people.
"We solved it through the mold temperature machine." Luo Jia said, "It is not convenient for me to tell you the specific technical details, but our mold temperature machine has added three new ones to the traditional four technical indicators. Metrics."
"In short, what I sell to you is not just a machine, but a complete set of solutions. If you don't use our mold temperature controller and replace it with another manufacturer's machine, don't ask me if you have any problems."
So it is!
Everyone suddenly realized ~IndoMTL.com~ The mold temperature machine is a kind of 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 public, but secretly sold the mold temperature machine to BYD and the others.
Thinking about it now, there is actually a reason why Luo Jia didn't mention the mold temperature controller.
It turns out that the mold temperature controller manufactured by Xingchen Technology is completely different from the previous products, and has undergone major technical upgrades!
Just when everyone was ecstatic and expressed that they would immediately expand production and make a big splash in the lithium battery industry, An Ran suddenly rushed in.
He didn't even have time to greet Luo Jia, he turned on the TV and tuned to the news channel.
"It exploded!"
"Ten minutes ago, South Korea really exploded!" An Ran shouted excitedly.
