Let you make mobile phones, and you build a photolithography factory

Chapter 84

Inside Ye Zi Company.

Nowadays, mobile phone sales are in full swing, and tens of millions of points are stored in the points store.

Ye Feng couldn’t help but drool when he looked at these points.

Ye Feng already has a complete plan for the company’s next step.

In addition to mobile phones, the company also wants to expand other businesses.

In addition to mobile phones, new energy vehicles are naturally the most suitable.

In previous conversations with Huang Ruijin, Huang Ruijin had promised to obtain a new energy vehicle manufacturing qualification for Ye Zi.

The biggest difficulty has been solved.

In terms of batteries, there is graphene battery. No battery is more suitable than graphene battery.

Ye Feng has been researching electric vehicles.

Compared with traditional oil-burning cars, the only difference between the two is that one uses oil and the other uses electricity.

The way to obtain oil is much easier than obtaining electricity.

Which place doesn’t have a gas station now?

Even if you are going to a place without a gas station, you can still get a bucket of gasoline in advance and take it with you in the car.

This is an advantage that trams cannot match.

However, the shortcomings are also obvious.

Oil prices are rising day by day. Oil is also a non-renewable resource and will be used up one day.

There are also issues such as traffic restrictions and license plates in current cities

, and exhaust from petrol trucks is also a big pollution problem.

Therefore, almost everyone is not optimistic about the future development of oil trucks.

In this case, new energy trams emerged as the times require.

All the shortcomings of the oil car have been perfectly solved on the electric car.

Compared with the price of electricity, the price of electricity is not very cheap.

The issue of traffic restrictions and license plates is not difficult at all. wrong! The word”limited traffic” exists in the dictionary of trams.

And even in cities like Beijing and Shanghai where it is extremely difficult to get a license, it is even easy to get a license worth tens of thousands.

It’s not easy to get a tram license plate.

The more crucial point!

There is no purchase tax on trams!!

In many aspects, in terms of money, the price/performance ratio of the tram is simply amazing!

However, the shortcomings of trams are also obvious.

Basically, all the advantages of gas trains are the disadvantages of electric cars.

The mileage is short and charging is difficult. Except in first-tier cities, where there are many charging piles, in smaller counties, there are often only two or three charging piles.

And charging is slow.

If you want to run a long distance or take a self-driving trip, you will consider whether this tram is feasible.

It’s simply impossible to take a self-driving tour on the fly.

The most important point!

Trams, trams, batteries are the key to trams.

And if the battery fails, the tram will basically be useless.

The cost of replacing a battery is not much cheaper than buying a new car outright.

And in terms of lifespan.

As long as the oil truck is properly maintained, its service life is extremely long.

Although China has a mandatory scrapping policy for oil trucks.

But in foreign countries, as long as the car can successfully pass the inspection, it can be driven all the time.

Therefore, many foreign cars are like that, where people die and the car remains, and one car is passed down through three generations.

Maybe World War II-era cars can be seen on the highway as long as they are well maintained.

In this regard, new energy trams cannot even catch up.

Nowadays, trams generally use ternary lithium batteries and lithium iron phosphate batteries.

Both batteries have their own merits, but they both have one drawback.

This is a problem with all lithium batteries.

Over time, batteries wear out.

Not to mention electric cars, everything with batteries will have this problem.

And tram batteries are very expensive

, so this is also a hurdle that cannot be bypassed.

Also because of this problem, as far as the value retention rate of the second-hand car market is concerned.

The value retention rate of trams is quite low.

Especially after the mileage and time go up, even if you sell it half and half, no one may be willing to take it over.

However, in terms of power system, electric vehicles have the advantage.

Oil trucks mainly use engines and gearboxes as the main power systems.

The electric car is the motor and battery method.

Because the power systems of the two are different.

The power of the oil truck needs to wait until the engine speed increases before it can reach its peak value.

The most obvious implication is that the manual transmission always starts in 1st gear, then 2nd, 3rd gear, and finally 5th gear, reaching the fastest speed.

Although starting in 5th gear is very impressive, there is a high probability that the engine will stall and the car will tremble.

Even for an automatic car, this process is unavoidable, but you don’t need to use your hands to control the gear. certainly! The more advanced the automatic transmission, the shorter this process will definitely be.

But the tram is different.

Any tram, even a junk tram worth 10,000 or 20,000 yuan, the kind that specializes in online ride-hailing services.

As long as you step on the accelerator, the speed will immediately reach the top.

As soon as you brake, the speed will drop immediately.

The only drawback is that this rapid change of speed will make passengers dizzy.

(Damn! The last time I took a taxi, it was a tram. MD almost made me vomit.)

So in terms of power, gas-powered cars simply cannot compare with trams.

This thing is a natural advantage and it is difficult to change.

Of course, that kind of top-end oil truck can definitely achieve this effect.

But comparing the two, one is more than one million, and one is tens of thousands….

Let’s talk about the technical difficulty of the two.

The technical difficulty of oil trucks is much higher than that of electric cars.

It is high-tech in every aspect, and the trams are simply incomparable.

It’s been a hundred or two hundred years since the oil truck came out, and now it’s very technical.

I dare not say that I have completely mastered it yet.

But how long does it take for the tram to come out? ?

It may only be about 10 years ago, but Tetra has already occupied a large portion of the automobile market.

Nowadays, in the car market of Longguo, there is traffic on the street.

At least one-fifth of the total is tram.

However, although the technical content is lower than that of oil trucks, it is still more difficult to break through.

The three core technologies of trams.

Electronic controls, motors and batteries.

The electronic control technology is very mature and relatively simple.

It may be exaggerated to think that it only takes a few minutes, but within a few months, you can easily come up with something.

The hardest part is the motor and battery!

It is precisely because of this.

That’s why Ye Zi’s next plan is to develop trams.

Graphene batteries are really suitable for electric cars.

All the shortcomings that originally existed on the tram were basically caused by the limitations of the battery.

When many trams run long distances on the highway, once there is heavy snow, all the vehicles are stuck on the road.

That would be a nightmare for trams.

Don’t turn on the air conditioner. It’s so cold that people will freeze to death.

Turn it on, this thing consumes electricity!!

When the battery runs out, won’t the car just break down on the road?

Moreover, even if the tram is parked on the side of the road, the battery will run out of power if the weather is too cold.

Maybe it was fully charged, but when I tried to turn it on, I found that it was out of battery…….

This has led to people suggesting that when buying a train, two mattresses are given as a gift.

It’s okay if the car breaks down due to lack of battery.

Don’t freeze people to death.

If there are mattresses, at least tram users can keep out the cold.

There are various problems that can be raised. In the face of graphene batteries, is this thing a problem? ?

Just check the battery before setting off to make sure it’s fully charged.

When something like this happens, turn on the air conditioner!!

Just turn on the 30% air conditioner!!

Open all the car doors again!!

Lest others think I don’t dare to turn on the air conditioner on the tram!

Not only do you have to turn on the air conditioner, but you also have to play the loudest DJ dance music!

Everyone, give me a high.

Ask why.

Without him! It’s just too much electricity!!

As for the motor.

This is like the engine of a car.

Every tram manufacturer keeps its own motors absolutely top secret.

Ye Zi definitely does not have such technology. (If you want to read Baoshuang novels, go to Feilu Novel Network!)

But this doesn’t mean that Ye Feng doesn’t have it.

Ye Feng opened the points store and looked at the dazzling array of motors in the store. He couldn’t help but be dazzled for a moment.

“What kind of motor should I use for this thing? ?”

Although they are collectively referred to as motors, there are many types of motors.

It is like car engines are divided into diesel and gasoline.

The two cannot be used interchangeably, and each has its own advantages.

The same is true for motors.

Today’s mainstream There are two main types of motors.

Permanent magnet synchronous motors and induction asynchronous motors.

The biggest difference between the two is that one has magnets and the other does not.

The principle of the motor, simply put, is to use the interaction between the stator and the rotor in the magnetic field. A device that rotates to generate power.

Compared with the motor on a battery car, electric cars have greater magnetic requirements.

The magnetic field generated by ordinary magnets cannot be used at all.

This is also the reason why there were no electric cars before.

Until RuFeBoron The emergence of magnets.

This kind of magnet can provide a strong magnetic field.

It can completely drive electric vehicles.

It is under this circumstance that Tesla came into being.

However, RuFeBoron is not completely without shortcomings.[]

The first is that the cost is high, and the second is that it is easy to lose magnetism in high temperature environments.

In order to solve this problem, rare earths were added to RuFeB.

The results obtained are obviously quite outstanding.

RuFeBoron with rare earth elements is a permanent magnet and will not demagnetize under almost any circumstances.

But rare earths are well known.

This is strategic material.

In terms of the degree of cherishment, this is much higher than your iron boron.

However, rare earths are not something that is very cherished in the Dragon Kingdom.

The rare earth stocks of Dragon Kingdom are the largest in the world.

Basically one-third of the world’s rare earths are found in Dragon Kingdom.

At least 90% of the rare earths used globally every year come from the Dragon Kingdom.

With rare earths, permanent magnets can be made through iron and boron.

The permanent magnet synchronous motor, as the name suggests, is a motor made of permanent magnets.

Therefore, all domestic car manufacturers in Longguo use permanent magnet synchronous motors.

The advantages of this type of motor are many.

Small size, light weight, energy saving, high power and so on.

The only difference between asking for flowers 0 is the high cost.

After all, rare earths are not cheap, and they are not easy to buy.

But this is like a shortcoming of a photolithography factory.

For the Dragon Kingdom, what are rare earths and iron and boron? It’s not a big deal, okay!!

This is why permanent magnet synchronous motors are used in China.

no way!

There are so many rare earths!

As for induction asynchronous motors.

This is exactly the motor that foreign scientists came up with after racking their brains.

Because they don’t have rare earths!

The rare earths are all in the Dragon Kingdom.

Every year, Dragon Kingdom’s exports of rare earths are rationed.

Just a little bit.

And rare earths have a wide range of uses.

All high technologies require this stuff.

After other countries obtained the rare earths from the Dragon Kingdom, they basically invested them all in military and aerospace.

And it’s not enough, so we can only tighten our belts and live a tight life.

If this aspect is not enough, how can it be used by your private enterprise to build cars? Without rare earths there would be no permanent magnets.

That’s why we came up with an induction asynchronous motor.

Because there are no rare earths and iron boron, the cost of induction asynchronous motors is relatively cheaper.

All foreign manufacturers use induction asynchronous motors.

But the induction asynchronous motor has a fatal shortcoming.

High power consumption!!

The battery life itself is a big problem, and it also uses an induction asynchronous motor with higher power consumption.

Can this thing be done? ? Of course, induction asynchronous motors also have advantages.

In terms of power, electric vehicles with induction asynchronous motors are more powerful.

This is why the performance of Tesla’s electric vehicles in accelerating from 100 kilometers to 100 kilometers is always so impressive.

Overall, both motors have their own advantages.

Permanent magnet synchronous motor with strong stability.

The induction asynchronous motor is more powerful.

As the saying goes, only children make choices.

As an adult, of course Ye Feng chooses to have them all!!

Directly launch a dual-motor car!!

In the normal mode, the permanent magnet synchronous motor is used as the main working motor and the induction asynchronous motor is used as the auxiliary.

In the power mode, the induction asynchronous motor is used as the main working motor, and the permanent magnet synchronous motor is used as the auxiliary.

Ye Feng browsed the points store for a while and found two motors

【Black technology permanent magnet synchronous motor technology – 200W】

【Black technology permanent magnet synchronous motor production line – 400W】

【Black technology induction asynchronous motor technology – 200W】

【Black Technology Induction Asynchronous Motor Production Line – 400W]

Without any hesitation, Ye Feng redeemed it directly.

Just 1200W points.

For Ye Feng now, this is not a problem at all.

Leaves meeting room.

At this moment, the Yezi executives were sitting with serious faces.

Ye Feng looked around and said slowly

“Everyone! Now that we at Yee Company have reached the pinnacle in the mobile phone field, it is time to diversify our products and enter other fields.”

For a technology company, this kind of thing is quite normal.

Whether it is DaMi Technology or Juhua Technology.

The mobile phone field only accounts for the majority of them at most, not all.

Except for DaMi Technology, which is not engaged in real estate, other walks of life are basically They are all involved in it.

Although the chrysanthemum industry is not as large as that of rice, it is still quite large.

It is involved in all aspects such as notebooks and routers.

After hearing what Ye Feng said, the senior executives were also very excited!

Finally!! Finally, we are going to enter other industries.

The larger the scale of Ye Zi, the better the wages and benefits will naturally be for their most intuitive experience. As soon as Ye Feng finished speaking, a senior executive immediately spoke:

“Chairman! I think we can enter the power bank market! After we entered this industry with graphene batteries, we had no rivals at all.”

As soon as I finished speaking, a high-level rebuttal arose.

“Power banks are obviously not advisable. Our Dashu 2 is not short of power at all and charges very quickly. Power banks are mainly used to charge mobile phones.”

“As our mobile phone market becomes larger and larger, the market for power banks is destined to gradually decrease. It is even uncertain that power banks will disappear directly in the future.”

“Let me tell you, we should still be in the tablet and laptop space!”

“These two fields are very similar to mobile phones. The graphene batteries and 4k240hz screens we have can be used in these two fields.”

Tablets and laptops are also the preferred industries for technology companies that specialize in mobile phones when launching new businesses.

This statement also attracted the approval of many senior executives.

After Ye Feng finished speaking, he remained silent. Just looking at these senior officials with a smile.

Gradually everyone stopped talking and turned to look at Ye Feng.

Ye Feng���There is always only one chairman and only one voice.

The most they can do is make suggestions.

The main decision-maker has to be Ye Feng.

Ye Feng said slowly at this time

“so! This time our Leaf will officially enter the field of new energy vehicles!”
