Early morning, very quiet.

Occasionally, I heard the faint sound of **** crowing, which chirped here and there, as if being rhythmic.

I also heard the next door start the motorcycle, and the sound of "puff puff" gradually faded from near to far. You don't need to look at it, you can tell from the sound that this motorcycle has some years.

"Daughter-in-law, what time is it?"

Mu Yang shouted habitually in a daze, grabbed the air with his right hand, and cleared his mind a little, only then did he know that Song Xuelu was sleeping at home.

Turning over, facing the sky, spread out your hands, lay flat like a "wood", and lifted the quilt covering your head a little, feeling a slight chill on your face, as if the wind was blowing in from the window.

Greentown's winter morning is still relatively cold, and Muyang didn't close the window last night.

The home is equipped with an inverter air conditioner, and the heating can be turned on, but Muyang does not like to sleep with the air conditioner on.

I touched it to the side and found my mobile phone, only to find that it was only 5:30 in the morning, and it was still dark outside.

Maybe it's because of the empty side, Mu Yang misses his wife.

I haven't been by my pillow for three nights, and I feel like something is missing.

At this time, she is still sleeping.

Mu Yang picked up the phone, hesitating whether to flirt with her, but finally dialed it, "beep beep" rang a few times, and a light and confused voice came from the other end of the phone: "Yangyang, what are you doing? ?"

"Hey, daughter-in-law, you're sleeping in the wrong position."

"You're so annoying. Early in the morning, I'm going to go back to sleep. I'm so sleepy."

"Well, I miss you, daughter-in-law."

"Oh, I missed you too."

Mu Yang hung up the phone and went back to sleep.

I don't know how long it took, Mu Yang habitually took it.

Hey, there is body temperature!

Feeling the familiar body, Mu Yang suddenly opened his eyes.

It turned out that there was one more person in the bed.

"Daughter-in-law, why are you here?"

"Don't be noisy, I drove here early in the morning, and I was sleepy." After speaking, Song Xuelu curled up like a kitten into Mu Yang's arms.

Muyang's house is only a few minutes' drive away from Song Xuelu's house. After checking the time, only half an hour has passed. This little girl must have just arrived.

"Um."

With the familiar feeling and smell around him, Mu Yang fell asleep soundly.

It was almost 7:30 in the morning, Mu Yang woke up and suddenly became interested.

Half an hour later, he was lying on the bed like a "too".

After resting for a while, she couldn't fall asleep. The daughter-in-law next to her was breathing smoothly and she slept soundly.

Mu Yang put on his clothes and stood outside the balcony enjoying the scenery of his hometown.

Standing on the highest point of the whole village, the whole village is unobstructed.

The soft warm sun was rising from the east, and the fog was gradually disappearing.

The countryside is not as noisy as the city. As the Chinese New Year approaches, villagers can be seen from time to time riding a battery car or driving a newly bought car to go out to the market.

After watching it for about 20 minutes, I went back to the room and saw that my daughter-in-law had woken up and was sitting in front of the dresser to straighten her hair.

Mu Yang has nothing to do today, but he is used to looking for something to do.

Last night, Mu Yang told his family about the Spring Festival Gala in Gui Province. He didn't want to go, but his family wanted to go there and experience the atmosphere.

In desperation, Mu Yang decided to go watch with the Song Xuelu family.

After having breakfast with Song Xuelu, Mu Yang sat at the computer desk in the bedroom, opened his laptop, sorted out the 48 plans, and dealt with the Hummer Company.

Recently, he had not received any achievement points from the reading system, which made him a little nervous, but Mu Yang believed that what should come will come, and there will be no shortage.

The progress of the reading system upgrade to level 7 has reached 34.3%, and John, the president of Hummer Company, reported to him the recent progress of car building.

The prototype did not go very smoothly, mainly due to the lack of spare parts.

Some automotive engineers are skeptical about the parameters of the battery pack and motor, and do not believe that the headquarters of Xinghai Group can develop such an advanced thing.

John suppressed the doubts and said that it was implemented according to the plan. If the headquarters can't come up with something, it is the headquarters' problem, but if their research and development progress is slow, it is their problem.

The battery pack and motor are shipped directly to the Port of Los Angeles on the west coast of the beautiful country. It takes about 13 to 16 days for the fast boat to sail at sea. If the boat is slow or the east coastline, the time will be longer, and the sailing time will take 30 days. about.

The battery pack is a dangerous item and is very heavy, and it is impossible to go through air logistics. The UPS6 fire in 2010 was caused by a lithium battery fire.

The Hummer Company is located in Detroit, Michigan, in the eastern part of the Pretty Country.

After the goods arrive on the shore, it is much faster to transport by road than by sea.

Last night, Muyang received an email from Yang Zifei, the vice president of China in Beautiful Country, saying that the battery pack and motor had been shipped to the company in the afternoon, and the engineers began to test the data individually.

Yang Zifei is a returnee Ph.D. from MIT. After working in the headquarters base for a period of time, Muyang appointed him as the vice president of the overseas Hummer company.

This morning, Yang Zifei gave feedback that the parameters of the battery pack and motor were fine, and he had conquered those engineers who had questioned before.

Seeing the report work of the two, Mu Yang sent a message to John: "If it is so difficult to build a prototype car, it is even more impossible for a mass-produced car;

It's okay to question, but if there are people who don't cooperate with their work and work negatively, one warning and two get out!

You must unite, not only unite the beautiful people, but also unite the Chinese people, whoever engages in splits will get out!

The batch of cars is progressing smoothly, and everyone will be paid half a year at the end of the year; if the listing is successful, the year-end dividend will be paid as promised.

You can improve the relationship between team members through weekly team building. "

John saw Mu Yang's message and knew that the boss was angry, so he conveyed his opinion to all employees, and started team building at night.

Mu Yang gave him a stick and then a candy, no one dared to object.

After Mu Yang worked for a while, Song Xuelu went upstairs to get a small plate of fruit and watched him enter a state of reverie. He glanced at the pictures and parameter configuration diagrams on the computer.

As soon as she saw it, she was fascinated by the special effects pictures of the car. She leaned her chin on Mu Yang's shoulder and asked gently:

"Yangyang, this is the Hummer EV? This car looks huge, wow, it's 5.5 meters, so long! It's still 2.2 meters wide!"

Song Xuelu has studied mechanical design. She seldom sees Muyang's office. She also has work to do. Now she has nothing to do at home, and she also pays attention to Muyang's car-making business.

Mu Yang laughed: "Yes, this guy is longer and wider than a full-size SUV. It is a platform for a small pickup truck, but it is made into an off-road vehicle with seven seats. All SUVs are younger brothers in front of it, Buddha. To block and kill Buddha, God blocks and kills God."

"Look at what you're saying, you're killing the gods, and the gods snap when you pinch them. However, with such a big car, it's inconvenient to park."

"If it is a car of this length, it is true in China, but people who can afford this car will definitely have a parking space or a small villa.

Taking this into account, it is equipped with a four-wheel steering system, that is, the four tires can walk diagonally at the same time, like a small crab, but it can only be used when parking, which is more convenient than SUV parking.

In fact, this car is actually sold to overseas customers who prefer big guys, especially ones that don't burn oil. Mu Yang said with a smile, he plans to make a smaller Hummer EV in the future, a full-size SUV with a length of 5.2 meters and a width of 2 meters, with a slightly lower price.

The big ones will be released first, and the wallets of potential consumers will be emptied. After another two years, the smaller ones will be released.

No matter how small it is, it doesn't matter, it will affect the reputation of Hummer EV.

"What's the price of this car?"

"It has not been decided yet, but the low-end version of the car will not be less than 850,000 yuan. It will be sold to Hummer. According to the price of 15,000 per kilowatt-hour, the battery of 160 kilowatt-hours is 240,000 yuan. Our cost is very low, 64,000 yuan. The cost of the motor is about 20,000 yuan, the price to Hummer is 60,000 to 70,000 yuan, and the body cost is between 320,000 and 350,000. The production cost of Hummer is about 630,000 yuan, and we have to guarantee 30% The above gross profit margin." Mu Yang explained.

Generally speaking, the cost of electric vehicles is shared, and the cost of battery packs accounts for 30%-45%, which is the largest cost.

The battery capacity cost of a battery pack in a battery factory is about 3,500 yuan to 5,000 yuan, and it is about 7,000 yuan when sold to a car manufacturer.

Therefore, if a car with the same configuration can run less than 20,000 kilometers a year, it is really not cost-effective to buy an electric car.

The gross profit margin of cars will not be very high. According to Tesla, the average gross profit margin of all models is about 30%, which is very high, even higher than that of Porsche.

The domestic Great Wall is about 18%, which is also very good.

Hummer

EV is equipped with many advanced elements, and Muyang must earn more.

However, his Hummer EV is not a necessity. He sells it expensive. Customers would rather buy other brands of cars. Moreover, even if the car is sold for a few years, the price is very stable and does not fluctuate much. The prices of many parts are transparent. .

The comprehensive gross profit margin of Muyang's control of Hummer EV is between 30% and 35%. In fact, if you count the part of the money earned by the headquarters of Xinghai Group, that is, the automatic driving system, battery pack and motor make some money first, the gross profit margin is definitely More than 40%.

"Then this car is really tall, not something ordinary people can afford." Song Xuelu said in surprise.

"Yes, the main customers who intend to buy Mercedes-Benz Grand G, Wrangler, and Land Rover Off-Road. In fact, in this size of off-road vehicles, it has no competitors. This market is completely blank." Mu Yang smiled confidently. .

In 2022, the price of the top Hummer EV in the previous life is about 110,000 US dollars, and the lower version starts at 80,000 US dollars, but the battery capacity is slightly worse than the current Xinghai Hummer, the motor is much worse, and it is one ton heavier. Compare.

Of course, the electronic components, such as the screen, are indeed much worse than in 2022.

Xinghai Hummer EV, Muyang believes that the speed of 0-100 kilometers per hour will be faster, and ordinary sports cars can't match it.

"It does feel like it looks good and is domineering, but the size is much larger, the interior is not much different, and it's electric, fast and quiet. Your bet with that foreigner, Nathan, seems pretty sure." Song Xuelu praised.

"There are still many problems to be solved. I think it's a bit difficult to plan mass production this year." Mu Yang sighed. The difficulty of building a car is mass production.

He planned for more than a year, and it was already a fast request.

Mu Yang made this request because he was confident that his technology was fine. Under normal circumstances, mass production of cars within two years would be considered very fast.

Hengda has been doing it for so many years, but it has not been successful.

Xinghai Group started from the foundation of automobiles. Many technologies were bought by Muyanghua's achievements, and there were many fewer detours.

If you don't spend achievement points to build a car, mass production in three years? Mu Yang did not have this certainty.

It's not that it's hard to build a car, it's that it's hard to build a good car.

In 2022, more than 400 vehicles have been recalled for a Hummer EV with electrical problems caused by water leaks.

Song Xuelu is a mechanic. He knows a little bit about building cars, so he comforted: "I'm in a hurry, take it slow, how is the structural strength of this big guy? It doesn't look like he's afraid of collision."

"As for off-road vehicles, it must be strengthened in all directions. Don't break the axle after a few jumps. It's an international joke. It looks big, but it's not very heavy. High-strength aluminum alloys are used in many places, with five doors and one door. The cover is made of aluminum alloy automobile plate." Mu Yang explained patiently.

There are three main factors for the structural strength of automobiles: material strength, structural design, and plate thickness.

Structural stiffness refers to the ability of the structure to resist deformation, such as the ability of a car door to be hit and change.

Different materials have different material strengths, which can generally be expressed by tensile strength;

Structural design refers to shape and form, such as I-beam, H-beam, and square tube. Even with the same weight of material, the structural strength is better than a round bar. This involves the calculation of the moment of inertia, which is clearer for those who have studied mechanics.

A layman writes a car essay, boasting that a certain part of a certain brand of car uses 1500MPa hot-formed steel plate, and the color is marked, such as red for hot-formed steel, yellow for ultrhigh-strength steel, and blue for high-strength steel.

If that's all, it can't be said that the strength of this car is good enough.

But there is no lift plate thickness?

Other cars use 1.2 mm, his car uses 0.8 mm;

The strength of other cars may be 1200MPa, his car is 1500MPa.

Whose car is stronger?

Under the same structural design, 1.21.2=1.44, 0.81.5=1.2, there is no doubt that the former has better structural strength.

Of course, under the same strength, the material strength is stronger, which can reduce the weight of the vehicle and save energy.

The Hummer EV five doors and one cover use a large number of aluminum alloy automotive plates. Although the material strength is not as strong as high-strength steel, the thickness of the plate is strengthened. Under the same quality, the structural strength is much stronger.

In terms of structural design, Muyang has optimized it, but in this respect, it will not be too different.

But no matter what, the structural strength of the Xinghai Hummer is better than most off-road SUVs, but not too much better. After all, this is a new energy vehicle, and the battery life is very important, so it should not be too heavy.

"Why, you want to drive this kind of car, it's really shocking for a girl to drive this style of car."

Song Xuelu smiled: "It feels quite interesting."

The mechanical guy likes this style of car, and she is also the mechanical girl, of course she likes it too.

"Then let's wait for the future 01 and the future 02 to come out, bulletproof level, no matter how you hit it."

"Um."

Mu Yang embraced her, kissed her, and ate a few grapes.

Today is the twenty-eighth Chinese New Year, and we are going to see the Spring Festival Gala.

Muyang's family of four, grandparents, uncle's family, and Song Xuelu's family of three had dinner together in the food court.

After dinner, Muyang's family of four, Song Xuelu's family of three, plus cousin Mu Qing, a total of eight people, drove two cars to the city.

The Spring Festival Gala in Gui Province starts at 8 o'clock, but it is necessary to enter the venue in advance.

Muyang arrived at the place where the Spring Festival Gala was held, and it was 7:30 in the evening. He called Song Shichang's secretary, waited for a while, and the secretary brought Muyang's family into the venue.

Muyang's family is in the front row. There are fruit drinks on the round table, and there is no melon seed snack food. The TV station is also afraid that everyone will eat retail, and the photographer will take pictures and affect the image.

Only the first few rows can sit at the round table, and there are not many. They are all family members of heavyweights, and those sitting in the back are all rows of chairs.

After the Spring Festival Gala started, Mu Yang looked at the stage, but his mind had drifted to the achievement point store.

The total number of achievement points is still 396.5, which has not changed for several months.

He is working on bulletproof glass technology.

The bulletproof glass standards of different countries are different. Each grade classification table has its own grade standard definition and test requirements, mainly divided by firearm types such as pistols, submachine guns, automatic rifles, bullet types, shooting times and shooting distances.

China's bulletproof glass standard is GA165-1997, and the new standard was not adopted until 2016.

There are currently 5 levels, with level 1 being the lowest and level 5 being the strongest.

The standard of the beautiful country is UL752, and the glass bulletproof grade is 10, and 10 is also the highest.

The 7.62 mm diameter warhead AK47 shoots at 4.6 meters, can resist five times at the same position, and the bulletproof level is 8.

Those that can resist sniper rifles are all level 9 and 10 bulletproof, but the same position can only be resisted once.

The bulletproof level is divided like this, but it is difficult to say whether it can be created.

Muyang's requirements for bulletproof glass are at least level 10, AK47 can't be broken after dozens of shots, can resist 50 Caliber sniper rifles no less than 5 times, and can resist heavy sniper rifles once. Well, as long as you don't hit the enemy only in the same position.

If it can reach this level, it must be the strongest bulletproof glass in the world.

Muyang's bulletproof glass technology ~www.mtlnovel.com~ can reach this level, and 20 achievement points is not a waste.

Of course, manufacturing is also very difficult. Before the holiday, the research and development progress was stuck at about 35%.

What Mu Yang didn't know was that the camera had captured him and Song Xuelu several times, and it could be said that they were the most photographed audience members in the audience. They even gave Mu Yang a big close-up.

The Spring Festival Gala on local stations is recorded and broadcast in advance, and it is usually broadcast before the New Year's Eve. On the New Year's Eve, the Y Shen Spring Festival Gala needs to be broadcast.

It's just that Mu Yang kept a smile on his face and didn't move. After a show, he didn't applaud.

Fortunately, the shot is only short-lived, and it doesn't shoot him all the time.

What Mu Yang didn't expect was that after the recording, due to his presence and many appearances, the ratings also increased.
