Technology company, I will become the light of China!

Chapter 300: Overturned a fuel vehicle, new energy battery pack test completed
For two consecutive days, the financial scythe of US dollar interest rate hikes was still waving, and its power gradually became apparent.

Before raising interest rates, the Nikkei 225 index of the Neon Island stock market was stable at 18240 points. After four days, the index had reached 14330. The entire market was ruthlessly bloodbathed by Wall Street financial giants.

Some opportunists and those who want to buy the bottom are also buried in the stock market.

As for "flying men", there have been no fewer than ten cases in Ginza, all of which were retail investors and hot money whose leveraged positions were liquidated.

Do you think you copied the bottom?
Do not!
In fact, it’s the top!

The tragic situation of the island country's stock market is not an isolated case, but a large number of examples.

Hong Kong stocks, A-shares, British stocks, French stocks, as long as it is a stock market other than rice stocks, the index has fallen by about 20%. Among them, Hong Kong stocks have been the key target of Wall Street giants. The decline once exceeded 30%, but they relied on massive rescue efforts. Funds are barely stable at around 24%.

It is no exaggeration to say that in just four days, "trapezes" were staged all over the world, and these "trapezes", without exception, were all levered.

however.

The stock market is not the biggest impact yet.

SWIFT international settlement system currently only supports US dollar settlement.

When the new sulfide battery enters the humid environment simulated by the equipment, the solid electrolyte instantly collapses and generates violent sparks.

"Our battery must be as stable as an old dog!" Gu Ren gave himself a thumbs up, and then continued: "And the solid-liquid hybrid battery is more stable than expected. A single battery module can store 15 kilowatt hours of electricity. It just depends on how many kilowatt-hours of battery pack you want to use, CEO."

Because solid-liquid hybrid batteries have front-end technology, it is not difficult to make a battery pack. At most, the battery module groups are connected in series and then a liquid cooling plate is added for heat dissipation.

……

The moment he heard the sound, Gu Ren immediately turned around and said: "The president is here? Just in time, I am doing the discharge test of the battery pack now. Once the stability is passed, it can be used."

"The battery pack has no technical difficulties." Gu Ren glanced at Lingchuan and continued: "After all, the battery pack is a series connection of solid-liquid hybrid batteries. It is not a new technology at all."

He had gone to bed at that time, and suddenly an idea flashed in his mind, and he immediately rushed back to the laboratory. Unfortunately, it only lasted one night, and there were still a lot of difficulties that had not been overcome. He often began to regret the wasted few minutes.

To put it simply, there is actually no technical obstacle to the battery pack. At most, the liquid cooling system needs to be optimized.

"So fast?"

As a large amount of U.S. dollars flow back to the United States, the number of U.S. dollars circulating in the market decreases, and its exchange rate gradually fluctuates.

"also."

If this problem is not solved, solid-state batteries will be nowhere in sight.

The currency exchange rate fluctuates, which makes it lose its stability. Some balance payment merchants pursue maximizing profits and start to delay settlement, waiting for the appreciation of the U.S. dollar before settling the bill.

Dragon Kingdom Deep City.

He immediately looked sideways.

Chen Xing's tone was filled with admiration.

Although the solid-liquid hybrid battery is not a new breakthrough technology within Longxing Technology, it has not been announced to the outside world. In theory, it is still new.

Chen Xing said hello.

The laboratory door opened automatically.

After several failures, Lingchuan murmured to himself: "It's a pity that I didn't catch the inspiration that night."

Longxing Technology Base Headquarters.

"drop--"

Chen Xing is not obsessed with this issue.

Lingchuan, a red-quality talent and chief of the energy laboratory, is constantly trying to add new sulfides to develop solid-state batteries.

Lingchuan thought it was another engineer and didn't pay attention until Chen Xing's magnetic voice came: "Chief Ling, how is the new energy battery pack?"

Things that originally cost $2 can now be purchased for $1.9, and decimals cannot stand calculations.

"How about stability?"

Nowadays, sulfide solid-state batteries have taken shape, but the problem is that sulfide will chemically react with humid environments.

Chen Xing was not surprised. As the "big money maker behind the scenes", he knew about it in advance and continued to ask, "Want to come over and take a look together?"

President?

After seeing that it was Chen Xing, Lingchuan put down what he was doing and stepped forward to respond: "The solid-liquid hybrid polymer battery pack has been made and is undergoing discharge testing at Chief Gu's side."

"Busy now?"

Energy Lab.

The access control card made a swiping sound.

"Zizzi-"

Lingchuan did not refuse.

After the two reached an agreement, they went straight to Gu Ren's laboratory.

At this time, Gu Ren was holding a notepad and pen, constantly recording data. In the tempered glass test area in front of him, a battery pack composed of multiple battery modules connected in series was continuously discharging.

The biggest impact of the US dollar interest rate hike is actually on the settlement of international trade.

The farce caused by the US dollar interest rate hike continues to affect the world.

The battery pack is not high-end. Anyone who has taken apart a power bank knows that it is actually composed of battery modules connected in series.

"let me see."

Chen Xing fell into thinking.

How big is the new energy battery pack?

If he remembered correctly, the new energy vehicles in the previous life could run about four to eight kilometers with 1 kilowatt hour of electricity. Normally, they could run about five kilometers.

Of course.

Battery life will continue to shrink in winter.

If you want new energy vehicles to quickly replace gasoline vehicles, mileage and endurance are very important. In previous generations, owners of gasoline vehicles could criticize new energy vehicles because of the endurance issue.

Like running a long distance and having to sleep one night in a high-speed service area, or the trouble of charging.

It takes time to lay out charging piles, but home charging piles are available for sale.

If the seller uses charging piles, he can still get a lot of money from users.

Now here comes the problem. If you want car owners to buy their own charging piles and still be competitive in the market, determining the car's cruising range is a top priority.

"What I want to build is a family car, no more than five meters long, no more than two meters wide, and about 2.4 meters high. According to this size, its battery pack should be 1.2 meters long and 20 meters wide. In terms of thickness, It’s about centimeters. Look at how many kilowatt-hours of electricity a battery pack of this size can produce.”

Chen Xing is not a scientific researcher, he is only responsible for assigning tasks.

After getting the data, Gu Ren fell into deep thought. Then he went to the computer on the side and opened the graphic design tool.

I saw him analyzing while designing: "Assume that the battery pack is 2.4 meters long, 1.2 meters wide, and 20 centimeters thick. We need to subtract the thickness of the battery protection shell."

"Continue to assume that the edge of the battery protective shell is 3 cm and the bottom thickness is 1 cm..."

"A single battery module has 34 series connections, and the size of a single battery is 15 cm long, 7 cm wide, and 3 cm thick..."

After a series of calculations, Gu Ren also got the data he wanted. He stood up again and responded to Chen Xing: "It's done. According to the size you gave, CEO, we can make a battery pack with a maximum power of 140 kilowatt-hours."

"140 kilowatt hours of electricity."

Chen Xing's eyes lit up.

Calculating based on the average of 1 kilometers per kilowatt hour, doesn’t that mean it can run 5 kilometers?

You must know that this is the middle value. According to the internal testing of previous manufacturers, it is basically calculated based on 1 kilowatt hour of electricity and 8 kilometers. This is why there is virtual electricity.

The temptation of 700 kilometers of real electricity, which car owner can withstand such a test?

Chen Xing doesn't like hiding technology. What he wants is to quickly seize the market. And the only potential rival is Tesla. There is no need for him to gradually release the technology.

The most important thing is that sulfide solid-state batteries are the king. Solid-liquid hybrid battery?

It’s just a product of energy transition!
After determining the initial strategic goals, Chen Xing continued to ask: "What about fast charging technology? How many watts of star flash fast charging does it support?"

"Currently, I have only tested 3KW and found no instability. After the discharge test is completed, I will test 5KW star flash fast charging."

Gu Ren responded quickly.

Regardless of the fact that the charging power of mobile phones is limited to 300W, that is not the limit of Star Flash fast charging, but the limit of the heat dissipation system.

Why can new energy vehicle battery packs withstand 3KW charging power?

Very simple.

Liquid cooling system!

In each battery module, a corresponding liquid cooling module will be installed to help the lithium battery control the temperature.

As long as the temperature of ordinary lithium batteries does not exceed 60 degrees, it will not leak electrolyte and cause spontaneous combustion and explosion.

If the mobile phone is modified with liquid cooling and the temperature is controlled, it can also withstand ultra-high-power charging.

But then again, mobile phones don’t need such a large charging power. After all, the battery is not as big as a palm, and 300W charging is enough for daily use.

"Then I'll take a look."

Chen Xing was in no hurry to leave.

His current tasks are two, new energy vehicles and building satellite base stations.

As for the satellite base station, Ren He hasn't given him a reply yet. He is probably still working hard to conquer it. As long as he says it's done, Chen Xing can immediately take it to Zhao Chenguang for assembly. He has also notified the Changxi Launch Center. .

Now when it comes to new energy battery packs, as long as the core battery pack is taken care of, the motor and other issues are just minor issues.

"Okay." Gu Ren didn't shy away from it. He was still confident in the solid-liquid hybrid battery.

……

As the discharge test ended, Gu Ren began to adjust the 5KW charging power. The data was a super large current and voltage of 220V32A, which was directly poured into the battery pack.

When the power is turned on, the blocked electrical energy will be converted into heat energy due to resistance, causing the internal temperature of the battery to rise.

In just the blink of an eye, the temperature has reached 50 degrees.

If it were an ordinary ternary lithium battery or a lithium iron phosphate battery, it would probably have started a liquid cooling cycle to dissipate heat.

But there is no solid-liquid hybrid battery pack. Because it uses an improved polymer battery separator, its temperature endurance limit is 100 degrees, and 50 degrees cannot reach its ignition point.

But when the temperature reaches 60 degrees, the liquid cooling circulation system finally starts.

As the liquid cooling system began to dissipate heat, the testing equipment showed that the temperature of the battery pack was controlled at 65 degrees and did not continue to rise.

"Would you like to try 7KW?"

Gu Ren looked at Chen Xing.

"superior."

Chen Xing wanted to see the limit.

Because of the tempered glass cover, the test is still very safe. Unless the entire battery explodes, similar to a C4 bomb, otherwise, it will be difficult to harm Chen Xing and others.

"Then I'll do it." After hearing this, Gu Ren adjusted the equipment parameters.

Not a moment.

The charging power increases to 7KW.

就在充电功率提升到7KW那刻，原本温度稳定在65摄氏度的固液混合电池开始躁动，温度来到了66摄氏度，紧接着是67、68、69…

While testing, Gu Ren also did not forget to record the battery data.

75 ...

80 ...

The temperature is still rising.

If this were replaced with an ordinary lithium battery, it would probably spontaneously ignite and explode.

While testing, the chief executives of the cooling laboratory and the Star Flash Fast Charging Laboratory also came to the scene to observe.

Because it is the first time to make batteries for new energy vehicles, they all know that there are many areas that can be improved. Now it depends on how long this solid-liquid hybrid battery pack can last.

"Stay still!"

"Stabilized!"

Suddenly, someone shouted in surprise.

Data testing equipment shows that the temperature of the battery pack is maintained at 7 degrees Celsius when charging at 87KW ultra-high power.

This result dissatisfied the chiefs of fast charging technology and thermal dissipation laboratories.

"Obviously liquid cooling is installed, but 7KW brings the battery pack temperature close to the limit. It seems that optimization will continue."

"Continued research is needed."

In their opinion, the charging power must be at least 10KW, otherwise it cannot be considered fast charging at all.

Chen Xing listened to the two people muttering to each other and comforted: "We are crossing the river by feeling the stones. Take your time. 7KW is already very powerful, but if possible, I hope to double this value and put the phone on The shock of fast charging extends to new energy vehicles.”

What are the advantages of fuel vehicles?
In a few dozen seconds, refuel and leave.

What are the disadvantages of new energy vehicles?
Charging is slow.

If the shock of being fully charged in 10 minutes can be extended to new energy vehicles, then new energy vehicles will no longer have any disadvantages.

It can run 10 kilometers in 700 minutes, and the cost of using the car is one-third that of a fuel vehicle. As long as the car owner is not stupid, he will know how to choose.

The most important thing is that if Chen Xing realizes all his ideas, he can still make money by selling charging piles.

"We will work hard to achieve 14KW power charging as soon as possible."

Liu Ziheng, the chief cooling officer, had just finished speaking, but Yang Bochao, chief of fast charging technology, doubled down and said: "If you want to do it, be the first and set the target above 20KW. The difficulty now lies in the heat dissipation system. During this time, we will study carefully how to reduce The temperature of the battery when charging.”

"Chief Yang, you are right."

Liu Ziheng echoed.

Looking at the highly motivated people, Chen Xing nodded slightly and said, "Work harder. Although the battery pack has enough power now, we need to keep improving to defeat the fuel-powered vehicles."

"it is good!"

Gu Ren immediately agreed and took the lead: "Dump the fuel vehicles and make new energy vehicles the mainstream!"

"Kill the fuel truck!"

"Kill the fuel truck!"

Scientific researchers shouted slogans one after another.

Behind the fuel vehicles is actually technology from Germany and Neon Island countries, and the patents are basically firmly in their hands.

It is no exaggeration to say that if others did not provide technical support, it would be difficult to build a differential, let alone an engine.

This is also the reason why there are many joint venture models. To put it bluntly, joint venture car companies are foreign OEMs.

If we can really overturn fuel vehicles and reshuffle the automotive field, we will not be far from our ambitious goal of exporting overseas.

When Chen Xing inspected the energy laboratory and checked the battery pack, a black Mercedes-Benz parked at the entrance of Longxing Base. Security immediately stepped forward and asked: "Hello, do you have an appointment?"

"No."

"Then I'll register you. What's your name?"

"Wei Yan."
