Technology company, I will become the light of China!

Chapter 385: A groundbreaking product that promotes the construction of charging pile infrastructure
"There are definitely highlights, and they are several data that are epoch-making." Hua Ming replied to Chen Xing slowly.

When Song Weiguo heard this, his eyes suddenly lit up and he quickly asked, "What is it?"

"800V high-voltage platform for the entire vehicle."

"800V?"

Song Weiguo was stunned for a moment.

Chen Xing was shocked and secretly sighed: "He is indeed a red quality talent. He actually bypassed the 400V high-voltage platform and directly made an 800V high-voltage platform."

What is a high pressure platform?

Simply put, it is the voltage standard adopted by the high-voltage system of electric vehicles. Under this platform, key components such as batteries, motors, and electronic controls of electric vehicles are designed for a voltage of about 800V.

To put it more simply, the 800V platform is like the "heart" of an electric vehicle, providing it with a stable source of energy.

People who exercise regularly will know that the heart rate of those who love to exercise will be slower than that of those who do not. This is because high-intensity training leads to increased myocardial contractility, and the heart ejects more blood each time than normal people.

What is the difference between 400V and 800V high voltage platforms?

The 400V high-voltage platform is equivalent to an ordinary person. He is out of breath after running two kilometers, and his heart can't stop beating wildly. He has reached the limit of his body. But the "athlete" of the 800V high-voltage platform is just beginning to feel it and his body is just warming up. This is the difference between the two.

Hua Ming saw Song Weiguo's confusion and explained systematically: "It is the power supply voltage of the vehicle. The larger this value is, the more powerful the vehicle will be."

"I see. For electric cars, the stronger the energy supply, the more power they have."

Song Weiguo replied.

He is originally from an engineering background and has some knowledge of voltage, current, and mechanical design.

Seeing that Song Weiguo understood immediately, Hua Ming continued, "Because it is a real 800V full-vehicle voltage platform, the vehicle's high-voltage circuit components, such as batteries, motors, electronic controls, PTCs, DCDCs, PDUs, MCUs, etc., all operate at the 800V limit."

"Of course."

Suddenly he changed the subject and continued, "The 800V high-voltage platform is only for our sulfide solid-state battery car. The polymer can only achieve 570V high voltage."

"Let's get back to the point. Under the high voltage environment of 800V, the horsepower of the motor is much stronger than when we first tested it, reaching 315 metric horsepower."

“315???”

Song Weiguo showed a look of surprise.

He looked at Chen Xing, and his eyes seemed to be asking: Are you sure you are building an ordinary car, not a sports car?

What does 315 horsepower mean?
Take Chen Xing’s car, the 2014 Mercedes-Benz S320, for example. It has a 3.0T V6 engine with a horsepower of 272.

272 horsepower is already the limit of the 2014 Mercedes-Benz S-Class. Even the new 2015 Mercedes-Benz S-Class only has 333 horsepower. How can your Pilot 001 have 315 horsepower?
The most important thing is that the price of Mercedes-Benz S-Class starts at one million, while for Pilot Automobile, Chen Xing's car manufacturing plan is in the range of 20 to 30. The price of the two differs by several times.

Noticing Song Weiguo's puzzled look, Chen Xing immediately organized his words and said with a smile: "It's also good to have stronger power and higher horsepower. It can save a lot of time when buying groceries."

Song Weiguo: "..."

Good guy!
It’s really great!

He used a car with 315 horsepower to buy groceries, while his own Audi A6 only had 190 horsepower. He suspected Chen Xing was fooling him.

With a maximum horsepower of 315, you call this a car for commuting and shopping?
"We can achieve 315 horsepower because we use a permanent magnet synchronous motor, which is smaller in size than an induction asynchronous motor and has a higher energy conversion efficiency. It can better adapt to daily use, but the corresponding cost is also relatively high."

Hua Ming took a breath and continued to explain: "But the induction asynchronous motor also has advantages. It is large in size, has a higher speed limit, and has a simple structure. If it is a sports car, it will be the best choice."

"understood."

Chen Xing took note of it silently.

To put it simply, the difference between permanent magnet synchronous motors and induction asynchronous motors is that the former has high energy conversion efficiency, which means it has a longer battery life, while the latter pursues a speed limit, has low energy conversion efficiency, and its battery life is greatly reduced.

Because Chen Xing's task for Huaming was to make a family sedan, which would also be the first car for young people, how to make good use of limited electricity was the top priority.

Song Weiguo suppressed his shock and asked, "What is the maximum torque?"

The maximum torque is the "strength" of the car. This parameter plays a decisive role in scenarios such as sudden acceleration, off-road escape, towing heavy objects, and climbing.

Off-road SUVs, such as the 2015 Land Rover Range Rover, have a maximum torque of 600. Ordinary family cars can only be dragged when playing tug-of-war with it.

"450N·m."

Hua Ming gave the number without hesitation, and then added: "Currently, the acceleration from 2.81 to km/h is seconds."

"2.81 seconds?" Song Weiguo's eyes flashed with surprise, and he quickly asked: "When did you measure the data?"

"In the next few days."

Hua Ming responded.

When he got the specific date, Song Weiguo was completely shocked. That is to say, the 001 seconds measured by Linghang 14 was in a weather with a temperature of only about 2.81 degrees.

Don’t think that the temperature will not affect the acceleration from 0 to 100 km/h. You must know that tires are made of rubber. Rubber will harden in low temperature weather, resulting in reduced elasticity and affecting grip.

During the acceleration process, the elasticity and grip of the tires decrease, so it takes longer to reach the expected speed, thus affecting the test results of the 0-100 km/h acceleration.

Moreover, in a low temperature environment, the density of the air will also increase.

Song Weiguo has concluded that if tested at room temperature, around 22 degrees, it is estimated that it can run in 2.7 seconds, or even a staggering 2.6 seconds. After all, its maximum torque has exceeded 450N·m, which is very scary.

After understanding the complete powertrain, Song Weiguo looked at Chen Xing again. The shock in his pupils seemed to be saying: 800V high-voltage platform, 315 horsepower, 450N·m maximum torque, and 2.81 seconds to accelerate from to kilometers. Are you sure you are building a family car?
Feeling that gaze, Chen Xing also felt that his car was a bit abnormal. He looked at Hua Ming and said, "The acceleration of 2.81 seconds from to kilometers is too fast and not suitable for daily use. Try to set a limit and reduce the performance of the vehicle."

“This one is available.”

Hua Ming had anticipated this.

He glanced at Lei Jun and Ren Guofei and continued, "Mr. Lei and Mr. Ren have proposed that vehicles should take into account different groups of people, so we have three models."

After the words fell, Ren Guofei, who had been standing aside and had not spoken yet, nodded and agreed: "Yes, we have set limits, namely energy saving, daily and sports modes."

"Cough cough."

Lei Bushi coughed twice, attracting everyone's attention and said, "Among these three modes, I actually want to change the sports mode to the combat mode. It sounds more impressive."

"Good fight."

Chen Xing nodded slightly in affirmation.

Liu Dongzi once said, never compete with Lei Jun in marketing.

The moment Lei Jun said "combat mode", he knew what the marketing genius was going to focus on.

If it is in sports mode, it feels very ordinary and cannot run fast.

But if it's combat mode, the passion will rise immediately.

Can Pilot 001 fight?

The acceleration from 2.81 to 320 km/h in seconds in cold weather is already very "combat" and faster than Chen Xing's Mercedes-Benz S.

"Then change it to combat mode." Hua Ming had no special feelings about the name and continued to introduce: "In energy-saving mode, our electronic control system will recover as much power as possible and limit the maximum horsepower of the vehicle."

"In daily mode, the car can accelerate from 3.1 to km/h in seconds. The horsepower and torque are also limited to a certain extent to prevent the owner from not adapting and causing tragedy."

"In combat mode, all restrictions are lifted, and energy saving is not considered. The power of the motor, electronic control, and lithium battery will all reach the limit values ​​I mentioned above."

"good."

Chen Xing couldn't help but praise.

Then, he looked at Song Weiguo and said, "What do you think, Chief Song?"

"very good."

Song Weiguo was equally impressed.

Automobiles are an area in which Longguo has never made any breakthroughs.

High-end engines, differentials, and corresponding power transmission systems are more dependent on foreign technology.

If the Longxing Group really succeeds this time, it will definitely make a significant contribution to modern history. He dare not even imagine whether the history books will give Chen Xing a separate page.

In the past, we had semiconductor chips, communications, and fast-charging technology, which had conquered mobile phones. Now we have solid-state batteries and complete vehicle technology. It is no exaggeration to say that we are the pride of domestic products.

"correct."

Song Weiguo changed the subject and asked, "Having said so much, can you let me test drive it to see the quality of our domestically produced cars?"

"this…"

Chen Xing was a little hesitant. He looked at Hua Ming, Ren Guofei and Lei Jun, seeking their opinions.

The vehicle is still being tested in a closed area and its safety performance is still unknown. If the vehicle loses control and something happens to Song Weiguo, no one here can take the responsibility.

"Commander Song, why don't you let me drive it, because our Pilot 001 has not yet been sent for quality inspection, and the safety aspects are still under study."

Lei Jun volunteered.

Ren Guofei waved his hand and also volunteered: "Let me do it. I watched this car being assembled and produced bit by bit. I will take the blame even if anything goes wrong."

"The car will be fine, please rest assured, because we use an integrated aluminum structure, plus the closed area, there are tire walls around to buffer, even at 100 kilometers per hour, life safety can be guaranteed."

Hua Ming said what was on his mind.

It takes great courage to test drive the first domestically produced electric car.

There are many cases of vehicle loss of control. Tesla has lost control many times abroad. No one can guarantee whether a probabilistic event will occur.

"Let me do it."

Chen Xing stood up.

With Hua Ming's guarantee, he believed in his red talent.

Since he said it was possible, it must have been foolproof. Besides, Longxing Heavy Industry of Linghang Automobile has now been transferred to the Longxing Group. He is the big boss behind the scenes, and it is reasonable for him to experience it personally.

"Don't argue. It's just that it hasn't been sent for a complete test. I know my limits. I wasn't afraid of driving a tank before, so how can I expect to be able to do anything wrong with a small family car?"

Song Weiguo didn't take the probability event of "possible loss of control" seriously at all. As a veteran who participated in the counterattack, his courage was unmatched by ordinary people.

He came to the left side of 800V's pilot car and opened the door directly...

next second.

He froze again.

“This interior…”

The center console has a super-large screen, and the seats are ergonomically designed chairs made of Nappa leather. There is no gear lever under the center console, only a few buttons and storage area.

"How do I drive without a gear lever?" Song Weiguo was confused.

He was now like a "Sankara" from the countryside who suddenly came to a bustling metropolis. The towering buildings alone opened his eyes and shocked his heart.

"Bang-"

The right door opens.

Hua Ming looked at Song Weiguo's stunned expression and continued, "Commander Song, you only need to step on the brake to turn on the power. The first button below the center console is the one-touch ignition. On the left side of the steering wheel are the turn signal and wiper, and on the right side are the shift paddles. If you want to engage the drive gear, step on the brake and pull down to enter the D gear."

"When driving, you can directly shift gears, and for P gear, just press the button at the end."

"There is also a mode selection button. It is on the left side of the control panel. It has a red warning border. Press it once for energy saving mode, and hold it for three seconds for combat mode."

"How about letting me drive it for a while first?" Chen Xing came behind Song Weiguo and continued, "This is the gear shifting mode of a sports car. Commander Song is very busy and probably not familiar with this driving mode. Let me demonstrate it first."

"Then...okay."

Song Weiguo was truly shocked.

As expected, if you stay in the army for too long and don't come into contact with new things in the outside world, you will be left far behind. He didn't show off, after all, he had never driven such a car before.

Chen Xing sat in the driver's seat, Song Weiguo sat in the back seat, and Hua Ming did not hesitate and also sat in the passenger seat.

Lei Jun and Ren Guofei looked at each other, and before the vehicle started, they quickly sat in the back seat, which just reached the maximum passenger capacity of five people.

Faced with the suddenly full vehicle, Chen Xing was also a little stressed.

If this "low probability event" happens, it will be a disaster. He has already imagined what will be on the front page of tomorrow's news. "Ding Dong——"

Chen Xing stepped on the brakes and powered on the vehicle. The dashboard flipped over and displayed the vehicle's current specific values.

Then he followed Hua Ming's instructions and pressed the start button on the center console. There was only slight vibration during the whole process.

Anyone who has driven a fuel car knows that when the engine starts, there is a strong vibration and roar.

Comparing the two, the tram was so quiet that one would suspect it had not started successfully.

"It's time to shift into gear."

Hua Ming reminded.

Song Weiguo opened his eyes wide, not daring to miss any details.

As a former second-generation rich man and now a first-generation rich man, Chen Xing has played with sports cars and is very familiar with paddle shifting. He gently paddles down while keeping the brakes firmly on.

"Ding!"

The vehicle emits a warning tone.

At the same time, the instrument panel also shows that the car has been engaged in D gear, which is commonly known as the starting gear or driving gear.

"Electric cars don't have a clutch. Once the president successfully shifts gears, the vehicle will automatically release the handbrake, and you can just drive now."

"Row."

Chen Xing lightly pressed the accelerator pedal.

Pilot 001 began to move forward. Out of caution, he did not say to pull the gear to full throttle. After all, if anything happened to the five people in the car, the whole Dragon Country would be shaken.

Even in daily mode, when Chen Xing stepped on the accelerator, he could clearly feel the seat pushing back, and the acceleration was very fast, reaching 60 km/h in the blink of an eye. This was when Chen Xing was relatively restrained.

"It's a bit fast."

Song Weiguo looked very carefully.

As soon as he finished speaking, Lei Jun quickly replied: "It is indeed a bit fast, but as a commuter car, it not only has to meet the needs of daily use, but we also try our best to make it take into account the driving pleasure of the owner."

"Yes."

Ren Guofei echoed and continued: "Only by taking into account the diversification of use can our cars be competitive in the market."

"I understand." Song Weiguo nodded, then looked forward and said, "Friend Chen, try the combat mode. I want to experience the limits of this car."

"no problem."

Chen Xing replied.

"Turn left later. There is a one-thousand-meter straight test area over there."

Ren Guofei pointed out a way.

"I understand." Chen Xing concentrated on driving.

Now they were passing through a circular raised area, and the vehicle was constantly bumping, which was a great test for the vehicle's suspension system.

Fortunately, the test section is not long, only one hundred meters, but there are also test areas for wading, gravel roads, speed bumps, and continuous speed bumps, all of which are very challenging for the vehicle's overall performance.

It is not known whether it is because Chen Xing is a good driver or the overall strength of Pilot 001 is indeed strong. Even if the road surface is complicated, the vehicle does not shake much. Song Weiguo was secretly amazed.

"It seems that the Linghang 001 not only has excellent performance, but also has an excellent overall driving experience. Longguo Automobile has finally seen the light of day."

He thought to himself.

After passing the continuous speed bumps, there is an intersection. To the left is the straight line test area, to the right is the uphill and downhill test area, and if you drive forward, it is the vehicle parking lot.

Following Ren Guofei's reminder, Chen Xing skillfully turned the steering wheel to the left, and then pressed and held the mode switch button for three seconds.

"Ding!"

The vehicle has a warning tone.

The rear wing in the rear area of ​​the car is raised, and the whole car seen from the side no longer looks like an ordinary family car at all.

As the driver, Chen Xing could clearly feel that the shackles binding this beast seemed to have been broken free.

The accelerator pedal is depressed.

"boom--"

The car roared.

"Why is there an engine noise?"

Song Weiguo couldn't help but ask.

Isn't it a motor drive?
Why does the motor drive make noise?

"This is simulated sound waves. As I said before, we want to increase driving pleasure for users." Lei Jun explained quickly.

"Yes, simulated sound waves."

Hua Ming echoed.

"I see." Song Weiguo was completely impressed. The intelligence and comfort of the Linghang 001 were much better than his Audi A6. If possible, he wanted to change his car to the Linghang 001.

"Sit tight."

Chen Xing reminded me.

Ren Guofei and Hua Ming silently grabbed the handle on the upper right side of the vehicle, while Lei Jun, who was sitting in the middle of the back row, held the front seat steady with his hands.

Seeing this scene, Song Weiguo was just about to ask if it was too exaggerated, but the sudden strong inertia made him fall backwards suddenly, and the back of his head came into close contact with the seat.

"boom--"

With the accelerator pedal fully pressed, the Pilot 001 roared like a bullet fired from a gun, shooting forward at high speed.

"You said this is a family scooter?"

"what???"

Song Weiguo complained in his heart.

He touched the back of his head. Fortunately, it was the Nappa seat that hit him, which was soft enough. If it was the old bus seat, he would probably have felt pain in the back of his head for several minutes.

"This car is going very fast. Commander Song, please hold on tight." Lei Jun reminded.

The one-thousand-meter straight test area passed by in a flash, and Chen Xing gradually and slowly braked, finally stopped, and engaged the P gear for parking.

"How about it?"

Chen Xing looked at Song Weiguo in the back seat.

Song Weiguo gave a thumbs up and couldn't help but praise: "One word, awesome, two words, awesome, I think this car is good!"

"If Chief Song says yes, then we feel relieved. Do you want to experience it yourself?" Chen Xing planned to give up the driving seat.

He had just tested it and found that his company's automobile industrial foundation was very good, and he had the confidence in it.

"Okay, I'll try."

Song Weiguo was not polite.

After the two exchanged seats, Song Weiguo performed a launch start. The specific operation was to step on the brake and accelerator at the same time, and the words "rocket start" appeared on the dashboard.

With a loud bang, the vehicle sped forward quickly.

As an experienced driver, Song Weiguo was very confident. After running through the closed test area, he drove directly out of the production industrial park. This confused Chen Xing and others, and they quickly reminded him.

"Chief Song, the car has no license plate!"

"It's not that there's no license, it's that there's no quality inspection!"

"Why don't we go back? It's quite dangerous. What do you think, Chief Song?"

"fine."

Song Weiguo waved his hand and looked ahead and said, "I already have a certain understanding of this car. Now that there are few cars on the lane, I can help you test it in advance."

His bold move not only made Chen Xing and others ashamed, but even Fengtian’s traffic supervision system couldn’t help but feel ashamed.

"Captain, Captain, come over here and see, there is a car without a license plate waiting at the traffic light."

Fengtian Traffic Management Bureau.

The police from the Sky Eye system shouted hurriedly.

The captain, who had been thinking of taking a nap, immediately perked up after hearing this and shouted, "Fuck you, who dares to drive without a license on my territory? You're asking for your life, right?"

When he looked at it carefully, he was stunned and asked quickly: "What kind of car is this?"

He has been in the industry for decades, but has never seen this type of car. It looks a bit like a Porsche, a bit like an Audi, and a bit like a Mercedes-Benz, but its front face is sharper than theirs, and it can even raise a spoiler at the rear. Even the traffic control system can't recognize what kind of car it is.

"Hey, come here and take a look at what kind of car this is. It looks like someone modified it and is driving it without a license in our area."

"What???"

All of a sudden.

Police from the Fengtian Traffic Police Bureau approached one after another.

When they came to the screen and looked at it carefully, they all shook their heads and said frankly that they didn't know what kind of car it was and it was most likely a modified one.

"Damn it, the modified cars are so arrogant, send out a team immediately and bring them in for tea."

Just as the captain was about to set off, his cell phone suddenly rang. It was his immediate superior, the director, calling.

"Hello, Chief."

He answered the call.

The next second, he immediately changed his expression and nodded, "Okay, I get it. Okay, okay, it turns out that our Chief Song and Longxing Group are testing the car. No wonder he drives so coolly and his driving skills are so charming."

"Yes, Chief."

The captain finished speaking and asked again: "Should we send a team of traffic police to escort them? After all, this matter..."

Before he could finish his words, the director on the other end of the phone interrupted him and said, "No need, Chief Song has a special plainclothes vehicle."

"understood."

As the call ended, the captain looked at the traffic police who had gathered around him and waved his hand, saying, "Okay, everyone, go back to your posts. It's all right. This is Longxing Group's test drive, our Fengtian's future pillar enterprise."

"So it's Longxing Group."

"No wonder I've never seen this car before. It turns out it's an internal test vehicle."

"After hearing what the captain said, I realized that the person in the back seat seemed to be Chen Xing, as well as Ren Guofei and Lei Bushi."

“Oh, it’s true!”

……

The people who were still doing road tests didn't know what was going on. After taking a stroll, Song Weiguo drove back to the car manufacturing factory.

After getting off the car, he couldn't help but exclaim: "This car is easy to drive, powerful, fast acceleration, and most importantly, long battery life."

Before Chen Xing and the others could speak, Song Weiguo added: "I think it can be promoted across the board, at least in Fengtian."

"What does Chief Song mean?"

Chen Xing vaguely guessed something.

Song Weiguo didn't keep the secret and smiled and said, "That's what you're thinking. The performance of the Pilot 001 is very good in all aspects. If you can include charging piles in the national infrastructure projects, you can save a lot of money and continue to invest in research and development."
