Chapter 456: Solid-state batteries come into play, what is the battery life?


"The peak charging of 520kW is a kilowatt. Are you sure that such a terrifying value will not cause the lithium battery to explode?"

"How awesome is the heat dissipation to suppress this? Longxing Group doesn't Will room-temperature superconducting materials be integrated? "

"Don't mention it. If there are room-temperature superconducting materials, I wouldn't be surprised if there is 50,000kW, because there will be no energy leakage, and there will be no heat conversion. , let alone detonate the lithium battery, at most it will explode when it reaches the capacity limit."

"520kW is so terrifying, far ahead..."

"Really far ahead..."

When the parameters of the polymer semi-solid-state battery were announced, the entire audience, including the CEOs of friendly merchants, all opened their eyes wide with surprise.

What is the concept of 520kW charging power?

Take the Model S60 released by Tesla overseas as an example. Its peak charging power is 70kW. If a dedicated supercharging pile is not used, the charging power is only 12kW. This is also the common power of foreign charging piles.

Polymer lithium batteries have a peak charging power seven times higher than the lithium batteries used by Tesla. This made Masik’s palms sweaty and he wanted to know how it was done.

Chen Xing pressed his hands, and when the sound at the scene weakened slightly, he smiled and said: "The parameters of the polymer semi-solid lithium battery should make many friends unable to sleep tonight, but this is our favorite What we saw, now let’s analyze the advantages and disadvantages of this battery one by one.”

“Wuhu, Mr. Chen is awesome!”

“Shuffle the cards!”

“As a Yadi electric car owner, I can’t even imagine the 528kW charging power, but Mr. Chen is as good as ever. It’s awesome!”

“This is the foundation of technology, it’s awesome!”

The applause and cheers on the scene came like a black cloud over the city, and Chen Xing’s eardrums were huge. Despite the pressure, he still talked and laughed: "Let's talk about these 120 kilowatt-hours of electricity first, and see how long the mileage can be brought by these electricity, and how much money can be saved."

Chen Xing paused for half a second, Quick Organization Language continued:

“As we all know, our new energy vehicles are driven by electric energy, and the lithium battery capacity is equal to the gasoline capacity of fuel vehicles.”

“Generally speaking, the capacity of family cars is The fuel tank capacity is about 50 to 60 liters. We combined the basic fuel consumption, air conditioning, driving habits and other data to come up with a relatively average fuel consumption value per 100 kilometers, that is, about 8.5 liters of gasoline will be consumed per 100 kilometers. . ”

“Through the numerical values, we can conclude that the actual mileage of a family car is between 500 kilometers and 800 kilometers.”

When Chen Xing was narrating, the corresponding PPT page also appeared on the LED screen behind him, making the data more authoritative.

But after all, we are not a professional research organization. After describing the fuel life, he quickly added: "Of course, since we are not a professional data research organization, the values ​​​​from 500 kilometers to 800 kilometers are for reference only."

Although Chen Xing said that it is not authoritative data, for experienced drivers, this mileage is recognized.

Don’t look at the fact that the fuel consumption per 100 kilometers of most cars is only 6 liters or 7 liters. That is just the fuel consumption of the basic power, which is not accurate at all.

The most classic example is the Luxjet. The official fuel consumption is about 8.7, but in actual driving it can reach an astonishing 13 or even 14 per 100 kilometers. It is no wonder that other car owners openly ridicule it. The car owner is a strategic partner of Long Petroleum.

“Now that we know that 500 to 800 kilometers is the limit of ordinary household fuel vehicles, let’s take a look at a road test video equipped with a 120-kilowatt-hour polymer semi-solid lithium battery. Pilot 001, what is its real battery life?”

Chen Xing turned his body sideways and quickly pressed the remote control in his hand.

Next second.

The actual test video appears on the LED screen.

"Hello everyone, I am Chen Xing. Today is the winter solstice and the weather is getting colder. Remember to put on some clothes. But when you see this video, it should be the press conference."

At the beginning of the video, Chen Xing, who was wearing a black down jacket, had just fastened his seat belt. He looked at the camera and told what he was going to do today like a friend chatting.

"Today we are going to test the actual cruising range of the Pilot 001, which is equipped with a 120-kilowatt-hour polymer semi-solid battery."

After speaking, he picked up the camera, pointed the lens at the dashboard and said, "Everyone As you can see, the car is now fully charged, so we will start testing without further ado.”

After re-fixing the camera position, Chen Xing in the video started the vehicle and drove out of the underground garage. , came to the streets of Shencheng.

At first, the video was not accelerated, but the driving process was boring and impossible to fully present, so it needed to be accelerated.

“Now I’m in Guangfu, I’ve run 114 kilometers, and I still have 104 kilowatt hours of electricity. On average, 1 kilowatt hour of electricity is between 6 kilometers and 7 kilometers.”

Preliminary battery life values The exposure made Ningde Times CEO Zeng Yu unable to sit still. He couldn't help but exclaimed: "One kilowatt hour of electricity can run 7 kilometers, and this is still in a winter environment and the heating is turned on."

As lithium As a battery technology company, he is well aware of the impact of winter on lithium batteries.

As we all know, the low-temperature environment of lithium batteries will cause the chemical reaction rate inside the battery to slow down, and the resistance of the electrolyte solution to increase, resulting in poor lithium ion crossing performance, reduced activity, and smaller discharge current.

To put it simply, the low-temperature environment will increase the viscosity of the electrolyte and even partially solidify, causing the conductive performance of the lithium-ion battery to deteriorate.

“Incredible.”

Wang Fu couldn't hold himself any longer.

If he remembered correctly, the discharge capacity of the 100-degree Shenxing battery in the CATL era was cut by 30% in winter. Even at room temperature, it is impossible to say that 1 kilowatt-hour of electricity can run six or seven kilometers.

“How can it be so energy-saving?” Masik was equally puzzled.

“How is energy saving and efficiency increased?” Honda Group CEO Otaki Kazuki frowned, with question marks written all over his face.

It is no exaggeration to say that polymer semi-solid lithium batteries have exceeded everyone’s expectations, including tens of millions of viewers in the live broadcast room.

“114 kilometers only consumes 16 kilowatt-hours of electricity, and an average of 1 kilowatt-hour of electricity runs 7 kilometers. Doesn’t that mean that the polymer semi-solid battery can run 840 kilometers?”

“More than that, far away Far more than that, I am a professional in energy storage materials. Lithium batteries will suffer energy loss in low temperature weather, and the proportion is between 25% and 30%. Mr. Chen tested it during the winter solstice and found that it did not run in extremely cold weather. In other words, the standard The range of the new version of Linghang 001 may reach more than 1,000 kilometers.”

“Holy shit, 1,000 kilometers?”

“Heating consumes more electricity than air conditioning. How brave. Point, 1100 kilometers!”

“Nothing to say, far ahead”

There are constant barrage in the live broadcast room. Although the test video is not over yet, based on the first information disclosure, the entire network has calculated the true battery life of the standard version of Pilot 001.

The video continued to play. Chen Xing headed north and arrived at the Liannan Ancient Village tourist area. He had a casual meal and drove directly to the west of Guangxi.

Every time he goes to a place to rest, Chen Xing will report the remaining power.

“Arrived in Guiliu, now I’m going to find a place to park and have a meal of snail noodles. I still have 31 kilowatt-hours of electricity. I’ve driven more than 600 kilometers. I visually estimate that I’m still more than 200 kilometers away from Pawo. I just want to go there. Nanning, the capital of western Guangdong.”

In less than five minutes, I witnessed Chen Xing traveling from Shencheng to northern Guangdong, and then from northern Guangdong to western Guangdong. It was like a cloud. travel.

After eating snail noodles, Chen Xing in the video did not take a break and drove directly to Nanning, and the battery gradually began to bottom out.

20 degrees.

10 degrees.

5 degrees.

When the lithium battery has only 3 degrees of power left, the center console screen will quickly remind you to charge it in time, and provide the corresponding charging pile location and occupancy status.

However, Chen Xing chose to ignore it and drove across the highway with only 3 kilowatt hours of electricity remaining and entered the jurisdiction of Nanning City.

"The battery has run out for the last time. Let's find an edge road to finish it."

When Chen Xing spoke, he turned the steering wheel and did not go towards the city.

After driving around for dozens of minutes, an emergency reminder popped up on the center console screen.

【Emergency reminder, the remaining power of the lithium battery is less than 1%. It is expected that the vehicle will completely lose power in 2 minutes. Please drive aside and pay attention to the car coming from behind. If you need emergency call service, you can directly call Out "Call". 】

Chen Xing drove on the right side silently, and a 120-second countdown also appeared on the center console.

As the number continued to approach 0, the speed of Linghang 001 began to automatically decrease, and there was no way to forcefully accelerate. As the countdown ended, the vehicle finally came to a complete stop.

Although he was lying down, Chen Xing remained calm, picked up the camera and recorded: "The odometer before departure was 4041 kilometers, and now it is 4891 kilometers, that is to say, the aggregation of 120 kilowatt hours of electricity It uses a semi-solid lithium battery, which gives Linghang 001 a cruising range of 850 kilometers.”

The moment the cruising range results were released, the audience applauded again.

The air conditioning and heating were turned on all the way from Shencheng to Nanning, and the actual driving range of 850 kilometers exceeded most fuel vehicles.

The screen in the live broadcast room switched back to the Shenzhen International Racing Circuit. Chen Xing, who was on the podium, walked calmly and methodically back to the center position from one side of the podium.

“850 kilometers of battery life, this is the answer given by our standard version.”

“Bah bang bang——”

The applause was thunderous and continuous.

Chen Xing waited quietly for a few seconds. When the applause subsided slightly, he continued: "120 kilowatt hours of electricity, 0.6 yuan per kilowatt hour, which is equivalent to 72 yuan, can run 850 kilometers. Let's compare it with a gas-powered vehicle. "

Speaking of this, he pressed the remote control, and the gasoline sales price list from four days ago immediately appeared on the LED screen.

No. 92 gasoline: 5.58 yuan per liter.

No. 95 gasoline: 5.95 yuan per liter.

No. 97 gasoline: 6.44 yuan per liter.

"As shown in the picture, the oil prices in eastern Guangdong Province on January 21 were 5.58 yuan per liter for No. 92 gasoline, 5.95 yuan per liter for No. 95 gasoline, and 6.44 yuan per liter for No. 97 gasoline. ”

Chen Xing did not pause at all and directly announced the answer: "As we just said, an ordinary household fuel vehicle consumes about 8.5 liters of gasoline for every 100 kilometers. In other words, the cost of 850 kilometers is about 92 octane gasoline. 403.31 yuan, 95-proof gasoline 429.29 yuan, 97-proof gasoline 466.4 yuan.”

“His!”

The audience who were not good at mathematics were shocked.

They thought about saving money with new energy vehicles, but they didn’t expect it to save so much!

“Damn it, the same mileage of 850 kilometers costs more than 400 yuan for a fuel vehicle, but only 72 yuan for a new energy vehicle!”

“Mr. Chen is really awesome, this man is really No need to brag, electric vehicles are truly new energy sources, and they save a lot of money!”

“850 kilometers, full air conditioning and heating, only costs 72 yuan, no, what kind of bicycle do I need to buy without thinking? That’s it for new energy. This is the big trend in the future!” “I unilaterally announced that fuel vehicles will be banned by new energy vehicles!”

“I have failed in math since I was a child! But this time, I finally understand that even if the electricity cost for charging doubles, new energy vehicles will save money than fuel vehicles!”

What do ordinary people look for when buying a car?

1. Quality.

2. Price.

3. Save fuel (electricity).

Quality represents safety and value preservation, price represents cost-effectiveness, and fuel (electricity) saving represents daily expenses.

In terms of quality, Linghang 001 has already demonstrated that the body structure materials are fully 2000 MPa and integrated die-casting is used to make the body stronger and lighter at the same time.

In the stands at this time, the bosses of friendly car companies all had dark faces. The parameter configuration of Pilot 001 made it impossible for them to find anything wrong, so they could only wait for Chen Xing's next step.

“Now that the cruising range has been announced, the next step is the charging issue that car owners are most concerned about.”

Chen Xing is still confident.

After pressing the remote control, switch to the next PPT page.

The LED screen at this time does not display the parameter configuration of the battery, but intercepts the coded comment content on Weibo.

Chen Xing did not hesitate and continued: "I saw many voices on the Internet saying that it only takes a few minutes to refuel a fuel vehicle, but it takes several hours to charge a lithium battery in a new energy vehicle."

"Here, let me first To dispel the rumors, it only takes a few hours to charge the pilot 001 from zero to full power, while the polymer semi-solid battery only takes 20 minutes.”

“20 minutes?”

Luo Hao. Not calm anymore.

BYD's Wang Fu, SAIC's Chen Hong, and Tesla's Masik pupils once again flashed with shock. They were about to say something, but Chen Xing at the podium did not give them a chance.

“With a charging time of 20 minutes and a peak charging power of 520kW, everyone must be curious about how we achieved it.”

Speaking of this, Chen Xing pressed the remote control, and behind him The LED screen screen switched again, and a demonstration picture of the fast charging setup appeared.

“If you want to achieve fast charging, you must have exclusive fast charging piles. We have invested tens of billions in the construction of exclusive charging piles across the country that can recognize the energy chip of Linghang 001.”

"After confirming the vehicle model, the fast charging pile will output a maximum charging power of 520kW to quickly charge the high-rate battery cells of the polymer solid-state lithium battery."

"At this time, someone may want to ask, Is the peak charging power of 520kW unsafe? Is there a risk of explosion of lithium batteries? Here, I will educate you. ”

Chen Xing pressed the remote control again to switch to the next PPT page.

“The reason why lithium batteries spontaneously ignite and explode is generally due to damage to the internal diaphragm, resulting in electrolyte leakage.”

“For example, if the temperature is too high, the diaphragm melts. This will cause the electrolyte to leak and cause a spontaneous combustion explosion. "Theoretically, as long as the internal temperature of the lithium battery is well controlled, it will not spontaneously ignite, let alone explode."
< br>"In order to achieve rapid cooling, our Longxing Group's cooling laboratory has designed an exclusive "Water God Liquid Cooling Temperature Control System", which uses new heat dissipation materials and a unique pipeline design to cover every battery After tens of thousands of charging tests, the temperature of the polymer semi-solid battery has always been controlled below 100 degrees. You can rest assured."

"Immaculate, simply perfect." After listening to Chen Xing. As the story unfolded, Luo Hao, the CEO of Iron Hammer Company, couldn't help but admire.

The parameters currently displayed by Linghang 001 made him, a billionaire boss who is used to driving a Maybach, unable to help but feel excited.

2000 MPa body structure strength, 850 kilometers of extreme winter endurance, and the most important thing is that the charging time only takes 20 minutes!

Luo Hao, like most ordinary people, refuses to accept new energy vehicles because of the charging time.

For fuel vehicles, it only takes a few minutes to refuel.

But if it takes several hours to charge your new energy vehicle, how troublesome would it be?

But now the results are announced, 20 minutes, 20 minutes to fully charge!

What is the concept of 20 minutes?

Just take a nap and pass.

Whether you are running on the highway or charging in the city, 20 minutes is an acceptable range and can be used to take a rest.

This is no longer just Luo Hao, even Ferrari enthusiast Duan Yongping was a little moved, and said: "Pilot 001 is really awesome, far beyond my expectations."

I thought that new energy vehicles were a rising star, and it would take some time to catch up with the predecessors of fuel vehicles.

Unexpectedly...

It was instantly killed!

Unlike the CEOs of friendly businessmen who were watching the excitement, the CEOs of car companies were collectively silent.

I thought that Longxing Group, Kunpeng Company, and Rice Company would not be able to produce any good cars, but I didn't expect that the parameters were exploding one by one.

Forget about integrated die-casting, it is also equipped with L3 level driverless driving, which is acceptable here, but it actually has a battery life of 850 kilometers. It is still winter, and the lithium battery life is discounted, and the whole journey Data run with the heating on.

How to play?

How to compete with others?

Wang Fu was silent, Chen Hong was helpless, and Zeng Hong wanted to leave. They only realized in hindsight that Chen Xing did not regard domestic car companies as opponents at all, which was why he did not hold a press conference for so long. Yes, the purpose is to do Tesla's job.

However, at this time, Masik's eyes had completely changed. He now seriously suspected that Long Guo had set a trap for him.

Obviously there is a "top car company" in the Dragon Kingdom, but they pretend to be unable to build high-end cars to confuse the world, and then trick themselves into signing a "gambling agreement" with the Magic City.

"Fake! I've fallen into a trap." Masik realized later and his breathing became rapid.

If this "Gamble Agreement" loses, Tesla will really be in ruins and be killed directly.

“At this point, we can only see if other car companies have technical reserves.”

Masik thought to himself that he knew very well that it was no longer possible for him to fight against Longxing Group, Kunpeng Company and Rice Company alone. He had to unite to resist this new car-making force.

However, what he didn’t know was that BMW Group CEO Nagel, Mercedes-Benz Group CEO Olaf Leiter, Audi Group CEO Dusmai, Honda Group CEO Otaki Kazuki, Toyota Group CEO Nishikawa Takahiro had all made their decisions. Determined to enter the field of electric vehicles when I return.

This means that other car companies have little technical reserves.

When the CEOs of the car companies were all surprised and speechless, Chen Xing on the podium spoke again: "The introduction of polymer semi-solid batteries has been completed. Next, it is time to introduce sulfide all-solid-state batteries, which have also been introduced. It’s called Thor Battery.”

The moment the words fell, the audience in the live broadcast room, which was already refreshing like crazy, became even more crazy, and they were all talking about sulfide solid-state batteries.

"Thor?"

"Holy shit, Thor battery, my intuition tells me that batteries with code names are not simple. They can't have a 1,000-kilometer battery life, right?"

"1000 kilometers is a sure thing. I value charging power and time more. I hope Mr. Chen will not disappoint me!"

"No, Mr. Chen is serious. Solid-state batteries actually exist, and they are called Thors. I feel like I may not be able to afford Linghang 001, it always feels too high-end.”

“I’m a student, I bought it for 99,000.”

When countless barrages appeared, car company CEOs and viewers watching the live broadcast around the world held their breath.

Semi-solid batteries are so popular, what will happen to all-solid-state batteries?

Chen Xing didn’t question it for a moment. He pressed the remote control and revealed the answer directly.

Battery capacity: 200 degrees.

Energy density: 299Wh/kg.

Charging power: current is 700A+, charging power is 520kW.

Maximum discharge power: 7.3kW.

Temperature tube system: liquid cooling.

“200 kilowatt-hours of electricity is 80 kilowatt-hours more than the polymer semi-solid battery. Can this be understood as an extra 560 kilometers of battery life?”

“More than 1,400 kilometers of battery life?”< br>


"Hiss, is this a solid-state battery?"

There were constant exclamations at the scene. Honda Group CEO Ohtaki Kazuki's eyes widened at this time, not because of the mileage, but because he discovered the charging power In that column, the current and power "peaks" disappeared.

What does this mean?

Current 700A+, charging power 520kW is no longer the peak value?

What is the upper limit of charging power?

He didn’t dare to think about it!

Now he just wants to go back to the hotel, slap himself hard twice, and wonder if he is dreaming.

Ma Siike, who was belatedly aware of the situation, also saw the clues. He didn’t dare to breathe. If possible, he really wanted to sit down and talk with Chen Xing and ask if he could surrender and lose half. The parameters are outrageous.

"As you can see, it is a 200-degree ultra-large capacity lithium battery."

Chen Xing smiled faintly, and continued with a slight arc at the corner of his mouth:

"Because the Thor battery is all solid-state, its battery life will not be affected by extremely cold weather. This is not only good news for our friends in the north, but also good news for car owners who pursue mileage."

As soon as he finished speaking, he He continued: "As I just said, if it is not affected by extreme cold weather, its actual battery life reaches 8 kilometers per kilowatt hour."

"Holy shit!!!"
< br>"No, 1,600 kilometers?"

"Thor battery!!!"

"Stop talking, far ahead!!!"

Scene of the press conference There were constant exclamations, and viewers all over the Internet were incredible at this value. The 1,600-kilometer battery life was beyond their knowledge of cars.

Charge once and run for half a month?

That’s too exaggerated! ! !

However, what they didn't know was that Wang Zha was still behind. Chen Xing gently pressed the remote control, raised the volume to suppress the cheers, and solemnly announced: "It still has charging time. Yes, it only takes 7 minutes to charge from zero to full! ”
