Chapter 300 Overturning a fuel vehicle, new energy battery pack test completed
For two consecutive days, the financial sickle of US dollar interest rate hikes was still waving, and its power gradually became apparent.
Before the interest rate hike, the Nikkei 225 index of the Neon Island stock market was stable at 18,240 points. After four days, the index had reached 14,330. The entire market was ruthlessly bloodbathed by Wall Street financial giants.
Some opportunists 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 are copying the bottom?
No!
Actually, it’s 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, with a decline of more than 30%. %, still relying on massive rescue funds, barely stabilized 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 influence.
The biggest impact of the US dollar interest rate hike is actually on the settlement of international trade.
SWIFT international settlement system, it currently only supports US dollar settlement.
As a large amount of U.S. dollars return to the United States, the number of U.S. dollars circulating in the market decreases, and its exchange rate gradually fluctuates.
The currency exchange rate fluctuates, which makes it lose its stability. Some balance payment merchants pursue maximizing profits and begin to delay settlement, waiting for the appreciation of the US dollar before settling the bill.
Things that originally cost 2 US dollars can now be bought for 1.9 US dollars. Decimals cannot stand the calculation.
The farce caused by the US dollar interest rate hike continues to affect the world.
……
Dragon Kingdom Deep City.
Longxing Technology Base Headquarters.
Energy Lab.
Lingchuan, a red quality talent and chief of the energy laboratory, is constantly trying to add new sulfides to develop solid-state batteries.
Sulfide solid-state batteries have now taken shape, but the problem is that sulfide will react chemically with humid environments.
If this problem is not solved, solid-state batteries will be far away.
“Zizzi——”
When the new sulfide battery enters the humid environment simulated by the equipment, the solid electrolyte will instantly collapse and produce violent sparks.
After several failures, Lingchuan murmured to himself: "It's a pity that I didn't catch the inspiration that night."
At that time, he had gone to bed, and suddenly an idea flashed in his brain, He immediately rushed back to the laboratory, but 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.
"Beep——"
The access control card made a swiping sound.
The laboratory door opened automatically.
Ling Chuan thought it was other engineers and didn't pay attention until Chen Xing's magnetic voice came: "Chief Ling, how is the new energy battery pack?"
President?
He immediately looked sideways.
After seeing that it was Chen Xing, Lingchuan put down the work at hand and stepped forward to respond: "The solid-liquid hybrid polymer battery pack has been made and is undergoing discharge testing at Chief Gu's place."
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.
To put it simply, there is actually no technical obstacle to the battery pack. At most, the liquid cooling system needs to be optimized.
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 go over and have a look together?"
"That's okay."
Lingchuan didn't 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.
"Busy?"
Chen Xing said hello.
The moment he heard the sound, Gu Ren immediately turned around and said: "The president is here? Just in time, I am currently doing the discharge test of the battery pack. Once the stability is passed, it can be used."
" So fast?”
Chen Xing’s tone was filled with admiration.
"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, which is not a new technology at all."
"How about stability?"
Chen Xing is not entangled in this issue.
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.
“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 imagined. A single battery module It can store 15 kilowatt-hours of electricity. It depends on how many kilowatt-hours of electricity you want to use as a battery pack.”
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. composed.
“Let me think about it.”
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 were basically about five kilometers.
Of course.
Battery life will continue to shrink in winter.
If new energy vehicles are to quickly replace gasoline vehicles, mileage and endurance are very important. In the past, 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 can be sold.
If the seller uses charging piles, he can get another handful of users’ money.
Now 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 the 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 one and a half meters high. According to this size, its battery pack should be between 2.4 meters long and 2.4 meters wide. 1.2 meters, the thickness is about 20 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 protective 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. Centimeters..."
After a series of calculations, Gu Ren also got the data he wanted. He stood up again and responded to Chen Xing: "It's over. According to the size you gave us, CEO, we can make a maximum of 140 kilowatt hours. Battery pack."
"140 kWh."
Chen Xing's eyes lit up.
Based on the average of 5 kilometers per kilowatt hour, doesn’t that mean it can run 700 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 goal, Chen Xing continued to ask: "What about fast charging technology? How many watts of star flash fast charging does it support?"
"Currently only 3KW has been tested, and No instability was found. After the discharge test is completed, I will test the 5KW star flash fast charge.”
Gu Ren responded quickly.
Don’t look at the charging power of mobile phones being 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 do not 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 is not in a hurry to leave.
He has two tasks at this stage, new energy vehicles and building satellite base stations.
As for the satellite base station, Ren He hasn't given him a reply yet, and 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 to assemble it at the Changxi Launch Center. He has also notified Bian.
Now for new energy battery packs, as long as the core battery pack is taken care of, the motor and other things are just minor problems.
"Okay." Gu Ren didn't shy away from it. He was still confident in solid-liquid hybrid batteries.
……
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.
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 reached 60 degrees, the liquid cooling circulation system finally started.
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.
"Up."
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 hurt Chen Xing and others at all.
"Then I'll do it." Hearing this, Gu Ren adjusted the equipment parameters.
A moment later.
Charging power increases to 7KW.
At the moment when the charging power was increased to 7KW, the solid-liquid hybrid battery, which was originally stable at 65 degrees Celsius, began to stir. The temperature reached 66 degrees Celsius, followed by 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 this is the first time to make a battery for a new energy vehicle, they all know that there are many areas for improvement. Now it’s time to see how long this solid-liquid hybrid battery pack can last.
“It’s not moving!”
“It’s stabilizing!”
Suddenly, someone shouted in surprise.
Data testing equipment shows that the temperature of the battery pack is maintained at 87 degrees Celsius when charged at 7KW ultra-high power.
This result dissatisfied the chief executives of fast charging technology and thermal dissipation laboratory.
“Obviously liquid cooling is installed, but 7KW brings the battery pack temperature close to the limit. It seems that optimization needs to continue.”
“Need to continue research.”
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 themselves and comforted: "We are crossing the river by feeling the stones, taking our time. 7KW is already very powerful, but if possible, I hope this value Double the price and extend the excitement of fast charging for mobile phones 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 700 kilometers in 10 minutes, and the cost of using the car is one-third of 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, the chief fast charging technology chief, 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 agreed.
Looking at the highly motivated people, Chen Xing nodded slightly and said: "Everyone, work harder. Although the battery pack has enough power now, we need to keep improving and overturn the fuel vehicles."
"Okay!"
Gu Ren immediately agreed and took the lead: "Kill the fuel vehicles and make new energy vehicles the mainstream!"
"Kill the fuel vehicles!"
“Kill the fuel truck!”
Researchers shouted slogans one after another.
Behind the fuel vehicle 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, let alone the engine, it would be difficult to build even a differential.
This is also the reason why there are many joint venture models. To put it bluntly, this is that 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.
While Chen Xing was inspecting the energy laboratory and checking the battery pack, a black Mercedes-Benz parked at the entrance of the Longxing base. Security immediately stepped forward and asked, "Hello, do you have an appointment?"< br>
“No.”
“Then let me register you. What is your name?”
“Wei Yan.”
