After I Crossed, I Became A King, and My Uncle Wanted to Rebel

The refining technology is not a big problem for Jiang Feng.

Taking a look at the graphene battery technical data and graphene refining technology and equipment, the price is not too expensive, and the two together are only 5,000 national shipping points.

Without any hesitation, Jiang Feng simply recited the purchase.

[Ding, the purchase is successful, deduct 5000 national transport points. 】

Then, he spent another 10,000 points to purchase the technical information of permanent magnet synchronous motor and AC asynchronous motor, both of which have various advantages and disadvantages.

Among them, the advantage of permanent magnet synchronous motor technology is that the rotor has no excitation winding, so there is no rotor copper loss, so the efficiency is high. Secondly, the high-performance permanent magnet material provides excitation, the given power is small, and the volume can be reduced. The rotor moment of inertia is small, so the dynamic performance is much better. In addition, in terms of power output, the power and torque-output are larger at low efficiency.

High power density; high energy conversion efficiency (90%-95%); low energy consumption.

But the shortcomings are also obvious.

Limited by the material problem, the cost is relatively high, the reliability is low, and the process is much more complicated. Due to the limited material problem, the service life and strength are attenuated. Permanent magnets are at risk of demagnetization in high temperature and vibration environments.

The advantage of AC asynchronous motor is that there is no permanent magnet high temperature demagnetization problem, which can prolong the working time of peak power, rated power and peak power. Secondly, the characteristics of the motor are less affected by the environment, such as winter, summer, rainy days and other factors. Start high torque, high speed torque adjustment.

The reliability is much higher, and the cost is relatively much lower, and the performance is good at high speed.

The disadvantage is also obvious, the rotor magnetic field comes from the stator excitation, there is copper consumption, and the energy conversion rate is lower than that of the permanent magnet synchronous motor. At the same power level, the volume is larger and the energy consumption is higher.

And in practical application.

The choice of permanent magnet synchronous motor is mostly to increase the battery life, which is suitable for comfortable cars or family cars.

The choice of asynchronous AC motor is more inclined to give priority to performance. Taking advantage of the performance output and efficiency advantages of AC asynchronous motor at high speed, when the car is running at high speed, it can maintain high-speed operation and efficient power use efficiency, and maintain the maximum power output. At the same time, reduce energy consumption.

Its representative model is the early Tesla Model S.

All in all, both have various advantages and disadvantages.

The reason why the permanent magnet synchronous motor is expensive is not only the technical complexity, but also the need for rare earth.

The effect of rare earths can not only be used in civil use, but also in industry, such as aircraft, tanks, missiles, electronics, etc., which are needed in almost all walks of life, and can be called "industrial gold". In addition, rare earths are scarce resources, which The price of it will only be higher.

Asynchronous AC motors are different.

There is no need for a rare resource such as rare earth, and the structure is much simpler, which leads to a much lower cost.

Choose to exchange two motor technologies.

At that time, it will be applied to different models and scenarios.

Secondly, it can also be mixed and matched, such as a combination of dual motors, which can provide greater power.

Meet the needs of different scenarios.

In addition, the price is not expensive, for him now, it is nothing.

Naturally, it will not be stingy.

The rest of the chassis, production lines, etc., he did not exchange.

If these are exchanged again, at least 40,000 or 50,000 National Fortune Points will be required.

Unlike motorcycles, cars require a lot of equipment.

There is no need to spend precious national fortune points to exchange things that can be done with money.

Although I didn't buy a chassis, production line, etc.

However, he still spent 500 points in exchange for some car blueprints.

Keep a spare.

In case, when the time comes to design, the designed car does not look good, then these design drawings can come in handy.

To know.

The appearance of a car is very important, and it is also the first glance, and the second is to study the performance.

The appearance is not good-looking, no matter how good the performance is, no one buys it.

Unless it is a person who pursues a performance car, how many people are there?

After finishing these, exit the system interface.

I looked at the time, it was almost twenty minutes.

It is estimated that Xu Dongping is almost here.

He got up and walked towards the living room.

"His Majesty."

After drinking tea in the parlour for a while, Xu Dongping arrived.

"Come on, sit down.

Looking up at him, Jiang Feng said indifferently.

"Thank you, Your Majesty. 35

Xu Dongping bowed and saluted, then found a chair and sat down.

Putting the teacup in his hand on the coffee table, Jiang Feng turned his head to look at Xu Dongping, who was sitting upright, and said with a smile: "I came here to chat with you. Today, Yanhong and I went to the city. Immediately, I found an infuriating thing. An Alto that sold for 20,000 to 30,000 yuan in foreign countries actually sold for 200,000 yuan in our Tang country.

0.•**•••••••

A Volkswagen Jetta sold for less than 100,000 yuan in Daxia, but in our case, it sold for 320,000 yuan, what do you think about this matter?"

"This..."

"It's really a bit too dark-hearted."

Xu Dongping was also surprised. It is normal to increase the price. For example, doubling it is considered too much. After all, including tariffs and transportation costs, as well as storefront and labor costs, it is normal to increase the price by half. The direct increase of 2 times, or even several times, really shocked him.

"Humph! 39

With a cold snort, Jiang Feng said with a cold face: "This is more than a black heart... Forget it, I took a look, most of the cars are still used cars. Used cars are sold for several times higher than new cars, It's the first time I've seen such a thing.

I am afraid that this kind of thing will happen to me in the whole world.

Xu Dongping's mouth moved slightly when he heard the words, not knowing what to say.

0......

"Okay, I came to you today, just to discuss with you, I plan to let Stellar Power enter new energy vehicles."

Glancing at Xu Dongping, Jiang Feng said indifferently: "To solve the problem, solve it from the root. Instead of importing other people's garbage, we will develop it ourselves..."

new energy vehicles?

Xu Dongping was stunned and looked a little dazed.

"Your Majesty, what do you mean by new energy vehicles?"

"You can also understand my electric car."

"electric car?"

Hearing this, Xu Dongping raised his brows.

It is said that he builds motorcycles, but he also knows a lot about electric vehicles.

There are electric motorcycles in motorcycles.

But electric vehicles, the technology of this thing is not mature at all, and building a car is not as simple as a motorcycle.

"Your Majesty, there are no mature cases of electric vehicles in the world. If you enter this rashly, you may not gain much. If Your Majesty really wants to change the status quo, I think you can consider entering the fuel vehicle market. The difficulty is relatively simple. Practical.

Afraid that Jiang Feng would be overheated, Xu Dongping hurriedly persuaded him.

Jiang Feng said with a cold face, "You don't have to think about the technical aspect. What you need to do is to buy equipment, then set up factories and recruit workers..."

"His Majesty,,,"

Xu Dongping wanted to persuade, but was interrupted by Jiang Feng raising his hand, "Okay, I have made up my mind."

"Yes! Your Majesty.

Seeing Jiang Feng's firm attitude, Xu Dongping nodded helplessly.

(Ps: Little flutter, I beg for full order, custom... I beg for it.) Righteousness.
