I asked you to save a bankrupt factory and you became the richest man in the world.

Chapter 344 Chapter 243-244: The big layout of battery technology! (Two chapters in total)
Time quickly came to October 2013, and now it is getting closer and closer to the launch time of Hillhouse P10.

The success of Hillhouse’s deployment in Brussels can be said to have inspired all Hillhouse people!
In the past, Hillhouse's products would only be sold in China. The relationship between sales price, sales volume, and R&D expenses can be said to be very stuck.

Every R&D department is frantically involution.

996 and 007 are the norm.

All departments feel that there are not enough people!
In fact, there are not enough people.

In order to reduce R&D expenses, Gao Huaijun now uses the method of paying one person to two people for the work of three people.

Give you a high salary, but also let you do the most tiring work!
Don't want to do it?
Think it’s too bitter?

There are people in Hillhouse who can't stand it.

Basically, among the college students recruited every year, more than 20% will be lost in the first three months, and then half of the remaining 80% will be lost in three years.

In this way, just like the big factories of later generations, there are still a large number of 985 and 211 graduates rushing to enter every year.

Every year, as long as Hillhouse goes to Hua Wu and C9 to recruit, the campus job fairs are basically packed.

Why?

There are many domestic companies offering 996, but not many are willing to pay high prices like Hillhouse!
In China, there is too little such high-profit enterprises.

But even Hillhouse, if it were in China, would definitely stagnate at a certain bottleneck, and then repeatedly torture its employees and barely survive.

The core reason is that China has a narrow market space and does not have huge consumption power to support a giant super technology company!

But now the success of Brussels Fulcrum has given these employees a lot of confidence.

It is because now that the market scope has expanded, the purpose of our work is completely different.

When there are foreign markets to share R&D costs, the R&D funds Gao Huaijun can provide will be correspondingly higher!

Better treatment!

In the hearts of everyone, even the most optimistic Hillhouse employees.

Everyone feels that for a long time in the future, Hillhouse’s core development strategy will be to use China as the core fulcrum and then slowly expand abroad.

And this time may still be more than ten years!

Everyone is lacking in confidence!

After all, foreign products are all high-precision, and foreign moons are rounder.

Deutsche's oilcloth paper is still lying in the sewer of Qingdao.

It is basically impossible for Chinese products to crush foreign products on a large scale.

However, while everyone was worried about this trend, only one person felt optimistic, even cheering.

That is Gao Huaijun.

Because the mass production of Hillhouse P1 is getting closer!

Under the hot spot of Brussels point expansion, Hillhouse P1 is too low-key.

But only Gao Huaijun knows that Hillhouse P1 is an absolutely epoch-making product.

Although it seems that the research and development of this product is very radical!
The deep ecosystem and fast charging system can definitely be said to be the most sophisticated among the most sophisticated.

The binding of deep ecosystem and smart home can better enhance customer stickiness.

At the same time, it can also fundamentally improve Hillhouse’s comprehensive profits!

Why is there a cold 1000 billion in the account of a certain coarse grain company in later generations?

Is selling mobile phones really that profitable?
Hongcooliang mobile phone costs less than 1000 yuan each, and the profit is only a few dozen yuan!
The real reason lies in the various derivative products in the Coarse Grain Mall!
Ballpoint pens, smart small desk lamps, smart small speakers, smart air conditioners, etc.

These products are all pushed out through the inherent sales channels, and there is no need to add new sales expenses. The profits of these products are extremely high!

Now Hillhouse Derivatives Company's annual sales are only a few billion, but its profits are close to 40%!
This level of profit is simply too exaggerated!

Gao Huaijun really couldn't imagine what would happen if the deep ecological closed loop developed to a mature form.

How many cold billions will be on his card!

By then, even if the big collision in mid-2019 befalls Hillhouse, Hillhouse can still easily avoid it.

However, such an excellent product encountered R&D difficulties.

"When using high current charging, we must ensure the safety of charging and discharging. When red dot batteries are connected in parallel, we also need to be vigilant about the mismatch in impedance and initial capacity."

"For internal parallel charging of multiple battery cells, additional management is required. If the two battery voltages differ by more than 400mV, the charger must prevent cross-charging. Only in the case where the lowest battery charge is too low to support the system load, Only then can you cross-charge for a limited time.”

"During the battery charging process, pushing greater current into the battery will inevitably generate a lot of heat. Without proper management, the battery can overheat or, in the worst case scenario, undergo a thermal runaway reaction, thereby causing the battery to explode."

Gao Huaijun listened to Hillhouse Battery Wang Shichong's speech and roughly understood why this battery was difficult to deliver.

The core reason is that the current battery density is not high, but in order to increase the battery capacity, more lithium ion elements will be used.

Lithium atoms are the most active elements in real life. In order to control the generation of heat, multiple small batteries are connected in parallel inside the battery to increase the battery storage capacity.

This is also a last resort.

And because of the internal parallel connection, a stronger battery control system and the development of battery control chips are needed.

But now, Hillhouse is not very mature in this system. Now it needs to strengthen the fast charging technology, which is equivalent to amplifying the power shortage.

The heat energy generated by fast charging is not comparable to ordinary charging speeds!
After all, increased heat is a side effect of increased charging current, so proper thermal management is necessary.

The simplest way to prevent the battery from overheating is to reduce the charging current, but this will extend the charging time of the battery.

This has entered an infinite loop!
So Hillhouse battery is very difficult now.

Gao Huaijun listened in silence for a while.

He now knows why the Sansang note series will explode in a few years.

This thing is not a major R&D factory, so I really don’t dare to touch it!

In later generations, there will only be a few companies with strong volume charging technology.

"I understand what you mean, it's just a trade-off between ideal (fast charging) and reality (safety and maintaining battery life)!"

"But this is not allowed!"

Gao Huaijun shook his head ruthlessly.

The strategy of the P series is to become a high-end mobile phone that supports each other with the mate series.

If there are only apps with deep ecosystems, consumers will definitely feel a lack of interest.

That's how they feel.

That's it?

Therefore, it is necessary to use high-end fast charging technology!
Because this is an issue that determines the fate of mobile phone manufacturers.

The functions of a flagship phone must be stable and reliable, and have strong differentiation.

This technology can be used not only on mobile phones, but also on cars!
At this moment, Wang Shichong was very upset after hearing this!

Although Gao Huaijun now requires 15W charging power, it is three times more than the original 5W.

It seems to be much less than the 120W of later generations.

However, the difference between the battery and circuit board design and 5W can be seen. A slight change is a rearrangement. The charge pump needs to be changed to a larger one.

From 5W charging to 15W charging, the wires have to be replaced with thicker and more wire cores.

Where can this be done by simply setting up a software protocol and replacing it with a high-power battery?

Another issue is product positioning and cost trade-offs. The flagship machine must have enough materials in other parts, such as top-level SoC, imaging system, screen, etc., all of which already have sufficient costs.

Then there is the high-power fast charging technology, and the cost is high.

If the price is too high, will it become a key decision-making point for target users?

No one understands this!
Just when Wang Shichong was thinking about how to answer Gao Huaijun, Gao Huaijun on the side said to Min Weiguo who was sitting, "The cost of stacking materials is going up. There is no need to be afraid!"

"The core problem now is actually the chip problem!"

“The control technology of battery chips is still very insufficient!”

"Remember, re-adapt the charger for this phone!"

"Don't save this little money on a small place like a charger."

"Remember, my exact words were no matter the cost!"

Gao Huaijun said in a calm tone, but very firmly.

Compared with the 15W of later generations, this 200W is extremely small.

I'm afraid of just this current, but the super fast charging at the back is useless.

Stop playing!

There is no adventurous spirit at all. It seems that Hillhouse has gradually become ill with big companies.

All the executives present couldn't help but look at each other.

They did not expect that Gao Huaijun would dare to be so radical in this technology.

After all, this is considered a high-end model!
However, Min Weiguo on the side tasted it.

he knows.

In order to achieve fast charging of batteries, the charger needs to provide large currents, and the battery needs to be able to accept these large currents safely.

Battery Transient Response Optimization (BTO) is one way to deal with this challenge.

Using this method, when the battery voltage reaches a certain threshold, the charger can instantly reduce the current supply, causing the voltage to fall back.

The charger then gradually increases the current until the voltage reaches this threshold again, and then decreases the current again. Pass

In this way, the current supply during battery charging is kept within the safe operating range of the battery.

So at the beginning, their idea was to make minor modifications and modifications on the original basis, just like the B737 broadcast, without any so-called updates and improvements.

But from a higher perspective, Gao Huaijun doesn't care about the gains and losses of a product at all.

Re-research and development of the charger will slow down the research and development progress, and will also increase the stand-alone cost of this mobile phone by more than 100 yuan.

But Gao Huaijun could afford the loss.

At most, the P1 phone is not profitable.

What's so great?

As long as it can support the rise of another flagship mobile phone, it can make up for the shortcomings of only one high-end model being launched a year and being in a dull period most of the time.

No matter how much money you spend, it's worth it.

Doesn’t Hillhouse even have the error tolerance rate to lose money on a mobile phone?
That is absolutely impossible!
The pain of high R&D expenses for this product can amplify the expected revenue several times, directly further increasing Hillhouse's power in the battery field.

Make sacrifices for the next step, the greater electric energy revolution strategy.

In comparison, what does a small short-term difficulty mean?
Even if the P series doesn’t make any money or even loses money for several consecutive models, it’s still worth it!

Since 1840, Chinese civilization has been unable to dominate the pulse of the two scientific and technological revolutions of mankind.

The core reason is that we are being strangled in terms of energy.

In Gao Huaijun's previous life, the new energy revolution was started by mistake due to the Europeans' strategy of meeting carbon standards.

But in terms of grand strategy, it can only be said that they are following suit.

Still not beyond the control of the grand chess game.

So in this life, Gao Huaijun hopes to be more radical in battery technology.

He needs to quickly promote the formation of China's industrial chain.

After roughly understanding what Gao Huaijun meant, the executives present had already begun to take action.

Various departments have also been mobilized for chip re-modulation. Under the policy of "concentrating efforts on big things", Hillhouse Chip and Hillhouse Technology are operating rapidly with unprecedented efficiency.

There are now more than three months left, close to four months, and this product, Hillhouse P1, will be released!

Moreover, in this process, some technologies will be the core reserves of the later electric vehicle strategy.

Overall, this option is a sure win.

At this moment, a sudden call came directly to Gao Huaijun.

"Hello, Xiao Gao! We haven't seen each other for a long time!" On the other end of the phone was the hearty laughter of the deputy leader of the Industry and Information Technology Department.

"That's right, the boss wants me to discuss it with you."

"We are going to vigorously launch the layout of large-scale smart charging piles, but the early pilot results were very poor!"

"There are almost no related products in operation in various cities now, so I would like to ask you, is Hillhouse sure about making pure electric new energy models?"

Hearing the leader's words, Gao Huaijun here couldn't help but smile.

China's desire to develop a new energy strategy for automobiles was a strategy that had already been launched before Gao Huaijun's reincarnation.

But there has been no leading company to help launch the strategy.

Most companies just want to cheat on subsidies and get new energy points.

Where are new energy vehicles likely to be vigorously developed?

Open new production lines and conduct targeted research and development.

Battery management system.

Targeted research and development for battery protection.

Targeted research on battery range.

Etc., etc.

These research and development all require real money to be invested.

Whose money was blown away by the strong wind?

Just make do!

The baby feels bitter in his heart, but he can’t express it!
