Technological Hegemony

After Luo Jia sent his partner away, An Ran anxiously asked why he predicted that the Samsung battery would have an accident, which seemed amazing.

An Ran's question also attracted the attention of other people. They quickly surrounded Luo Jia, as if he would not give up until he told the truth.

"I'm not a wizard, so I don't have the ability to see things." Luo Jia said with a smile, "Come on, go to my office, and I'll explain it to you."

So, the group returned to Luo Jia's office.

Luo Jia spread out a few sheets of white paper on the desk and drew sketches on them with a pencil.

They are the structure diagram of the lithium cobalt oxide battery, the discharge characteristic curve, the charging characteristic curve, the structure diagram of the existing charging pile, the power time-sharing diagram, etc.

Although the stick figure is crooked, everyone can still understand the general meaning of Luo Jia.

"Each design seems to have no problem, but when combined together, there will be a big or small problem. In the solutions announced by Samsung and LG, I have not seen it. They have made plans for this problem, so Judging them is likely to underestimate its destructiveness." Luo Jia said.

An Ran and others were studying on the table. They are also one of the most powerful brains in the company and even on this earth. If Luo Jia told them the answer directly, it would be meaningless. It would be more enjoyable if he could think of it himself.

Luo Jia sat on the sofa beside him, made a cup of coffee, and continued to meditate with his eyes closed.

It was completely different from the early stage of entrepreneurship, the pressure was increasing, and the cruel reality was like a race, surrounded by Bolt-level opponents, and even Bell Labs ended up in person.

So Luo Jia has to go all out. He spends a lot of time reading and researching every day.

As the head of the tough guy group, his job is like drawing a blueprint, making a precise top-level design, and then handing over the details to his employees to turn the blueprint into reality step by step.

This job is very important. After all, sea navigation depends on the helmsman. If the helmsman is crooked, the ship will go directly to the Mariana Trench.

Only ten minutes later, Luo Jia heard An Ran exclaim.

As expected of a genius, An Ran understood Luo Jia's meaning so quickly, which made Luo Jia somewhat unexpected.

The ink pen quickly calculated on the white paper, and finally got a series of very complicated data safely,

Pointing to this string of data, he said to Luo Jia, "The explosion is due to the thickening of the electrolyte interface!"

Luo Jia nodded, smiling, "Go ahead."

An Ran spoke quickly: "Lithium cobalt oxide battery has the highest capacity among the six major lithium battery systems, but it has a flaw, which is its service life."

"The negative electrode of the lithium cobalt oxide structure adopts a layered structure. During discharge, lithium ions move from the positive electrode to the negative electrode; the opposite occurs during charging, and the flow is from the negative electrode to the positive electrode."

"In order to increase the life of lithium batteries, Samsung and LG have injected nickel, manganese, and aluminum mixed materials into the lithium batteries."

"The idea of ​​adding mixed materials to solve the problem of life is not a problem in itself, but this time their design density is extremely high, which means that their charging power must also be increased accordingly, and the problem of lithium plating on the anode during the fast charging process will be eliminated. When the geometric multiple is enlarged, when the critical point is broken, the problem of lithium plating on the anode will lead to the problem of sei thickening.”

"The structure of lithium cobalt oxide is just layered. If the sei thickens to a certain extent, it will increase the internal pressure and cause the lithium battery module to expand during charging."

After An Ran finished his conclusion, everyone applauded at the same time. His thinking was clear and concise. He deserved to be a genius who received a double doctorate at the age of 23.

Luo Jia was also very happy. Assuming that An Ran got the extraterrestrial inheritance, this guy must have done a better job than himself, but unfortunately there is no such option in this world.

Luo Jia and An Ran carried out rapid calculations on the calculation paper. It was definitely a pleasure to watch them use their pens and brains to perform calculations that required powerful scientific calculation programs.

Everyone shook their heads one after another. It is really incomparable to compare people with popularity.

Luo Jia and An Ran are like two biological computers, their thinking speed is too fast. If the brainstorming group is composed of a group of monsters, they are the two most vicious of them.

It didn't take long, and the results came out. The calculation conclusions of the two people are completely consistent. The problem of SEI thickening will only occur during high-power and high-density fast charging and discharging. In addition, the designs of Samsung and LG are actually perfect.

The embankment of a thousand miles collapsed in an ant's nest, and now is a real example.

With the explosion in the direction of Ulsan, Samsung, LG, and even the future of the entire South Korea were all blown to pieces.

The others applauded enthusiastically, excited for Luo Jia and An Ran's genius performance.

Luo Jia left the ink pen on the table and shrugged, "Actually, there is also an element of luck in it. Although I thought that their design might go wrong, I didn't expect it to blow up so badly."

Everyone nodded. What science needs is not rigor, but absolute rigor. To do anything in the future, you need to do more calculations.

"Let's stop here today." Luo Jia said, "It is imperative to put lithium batteries on the car, and there is not much time left for us. Although the front-end electronic control has been solved, we still need to solve the back-end electronic control. That's a huge problem too."

 …

As Xingchen Technology intends to enter the automotive industry, Luo Jia also began to feel the sourness of the liver, and he was tortured by the back-end electronic control system.

The front-end electronic control is how to manufacture high-quality and highly consistent batteries, while the back-end electronic control is how to scientifically manage tens of thousands of batteries.

It is enough to manage tens of thousands of batteries at a time, but also to study how the battery pack cooperates with the transmission system to improve the efficiency of discharging and charging, and output the maximum power with the least energy consumption.

How to ensure that the temperature of each battery is consistent, in case one or two batteries in the battery pack decay too quickly, how to repair it, the repair cannot be completed, and how to shield the damaged battery.

Anyway, in general, the back-end electronic control is also the lifeblood of the vehicle safety, in addition to the cruising range, vehicle maintenance costs and so on.

Luo Jia and the entire hardware team are in pain and happiness. As a new company that has just been established for one year, it lacks experience in the huge and profound automotive industry. Although the introduction of talents has been going on, it is still difficult to make up for the lack of experience in the short term. .

Luo Jia maintained a work intensity of sixteen hours a day, and the office was filled with coffee and Red Bull, in addition to a large number of calculation papers and design sketches.

Although he is promoting paperless office, he is still not used to it, and prefers to trust the pencil and draft paper in his hand.

After another two days of busy work, Xu Chunbiao finally came back from Korea.

He didn't go alone, he also brought eight brothers from the security office with him.

Every employee in the security department was carefully selected by Luo Jia with the eyes of the sky. They retired from the field army or the reconnaissance army. They have a clean history, and their character and morals are impeccable.

The security office does not stand guard at the gates. They have a special office with 173 monitors in the office, which can clearly observe the entire base.

They will also patrol the company, but they wear the same clothes as everyone else, but with superb eyesight, they keep looking at dark corners, looking for suspicious infiltrators.

Anyway, Xu Chunbiao and more than 50 retired soldiers from the security department are the entire security force of Xingchen Technology.

They are divided into five shifts to ensure that there are about ten people on duty in the company at all times, the wages are top-notch in the country, and there are extra overtime pay for overtime work, and the company covers all meals and lodging.

Globally speaking, Huaxia has excellent law and order.

Luo Jia felt that the current defense force was enough, and it wasn't Mexico where there was a lot of bullets. There was no need to recruit a large group of men in black suits and sunglasses like in the movie. If there was anything to do, the best way was to call 110. Spectrum.

Luo Jia asked Xu Chunbiao to sit on the sofa, made two cups of black tea, and handed him a cigarette.

Xu Chunbiao seemed a little frustrated, he did what Luo Jia said, and after arriving in South Korea, he immediately divided into three groups, went to the three major test tracks in South Korea, and took pictures of every move on the test track with a telephoto lens.

This is not a rare thing. Many car magazines and websites will specially send people to watch the test track. Once Hyundai has some new models to test, they can take first-hand spy photos and put them on the magazines and websites. Great for car enthusiasts.

Luo Jia once read in car magazines that even in Alaska, Iceland, Norway, those proving grounds that specialize in testing the performance of cars in extreme cold conditions, there are also car paparazzi who are not afraid of the severe cold and have been stationed for a long time.

In addition to the media, the world's major automakers also need information on their opponents' new models, and they will also send people to keep an eye on them.

In short, according to Luo Jia's arrangement, Xu Chunbiao mixed with those car paparazzi and gathered on a hillside, waiting to shoot the scene of the explosion of a modern car.

But due to the problem of the shooting angle, they didn't take any pictures, and they didn't know where so many pictures and videos came from, so Xu Chunbiao was very disappointed.

Luo Jia smiled, those videos and pictures still need to be guessed, it must be the power of the authorities of various countries, if I knew they were so enthusiastic, I wouldn't let Xu Chunbiao make this trip in vain.

After comforting Xu Chunbiao, Luo Jia asked him to go back and rest.

The brothers who went to South Korea on this business trip all took a vacation. After all, they have no credit but also hard work. For a whole week, the three of them took turns to be on duty. physical strength.

The Administration Department has recently set up a travel office. As the scale of Xingchen Technology is getting bigger and bigger, it is no longer possible for the whole company to travel like it did in the early days of its business.

The role of the travel office is to help employees arrange vacations reasonably and make good use of the free travel benefits provided by the company.

Luo Jia insisted that everyone go out more, after all, only by experiencing the world for themselves can they better understand their opponents.

All employees travel twice a year at public expense, regardless of the destination, and they can find a travel agency wherever they want to go, and let them arrange visas and accommodation on their behalf. Such favorable conditions are the only one among domestic high-tech enterprises.

Time flies, and Luo Jia continues to think hard about getting the back-end electronic control. At the same time, the three major car manufacturers have started plans to put lithium batteries on the car.

At present, Luo Jia has two troubles, both of which are big troubles.

High-energy electric vehicles with a battery life of more than 600 kilometers have strict electronic control requirements and need to use a new, higher-level electronic control system.

Why is Luo Jia obsessed with the new generation of electronic control?

Because it is only the first-generation product of Xingchen Technology at present, and the battery life of 600 kilometers has just started. In the future, batteries with higher energy will come out. Electronic control problems must be prepared for a rainy day.

When even Xingchen Technology did not handle the high-energy electronic control, the three major factories had even more difficulties, and they sent their electrical engineers around in a hurry.

Another problem is the anger of domestic giants.

They were shocked to see that Luo Jia gave the world's best lithium batteries to BYD, Great Wall, and Geely, three small and medium-sized factories, but did not give them to them.
