Chapter 385: A Groundbreaking Product that Promotes the Construction of Charging Pile Infrastructure

"There are definitely highlights, and they are several epoch-making data." Hua Ming replied to Chen Xing slowly.

Song Weiguo's eyes lit up when he heard this, and he quickly asked: "What is it?"

"800V high-voltage platform for the whole car."

"800V?"

Song Weiguo was stunned.

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

What is a high-voltage platform?

Simply put, it is the voltage standard used by the high-voltage system of electric vehicles. Under this platform, the battery, motor, electronic control and other key components 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 beats slower than those who don't like to exercise. This is because the 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, who is out of breath after running two kilometers, and whose heart can't stop beating wildly. He has reached the limit of his body, but the "athlete" of the 800V high-voltage platform has just started to feel it and his body has just warmed up. This is the difference between the two.

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

"I understand. For electric vehicles, the stronger the energy supply, the more powerful it is."

Song Weiguo replied.

He was originally from an engineering background, and he still had some research on these voltages, currents, and mechanical design.

Seeing that Song Weiguo understood immediately, Hua Ming continued: "Because it is a real 800V full-vehicle voltage platform, the high-voltage circuit components of the vehicle, such as batteries, motors, electronic controls, PTC, DCDC, PDU, MCU, etc., are all running at the limit of 800V."

"Of course."

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

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

"315???"

Song Weiguo flashed a look of surprise.

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

What does 315 horsepower mean?

Take Chen Xing's commuter car, the 2014 Mercedes-Benz S320, for example. It has a 3.0T V6 engine and a horsepower of 272.

272 horsepower is the limit of the 2014 Mercedes-Benz S-Class. Even the new 2015 Mercedes-Benz S-Class has only 333 horsepower. How can your Pilot 001 have 315 horsepower?

The most important thing is that the price of the Mercedes-Benz S-Class starts at one million yuan. The Pilot Automobile, Chen Xing’s car manufacturing plan is in the range of 200,000-300,000 yuan, and the price of the two is several times different.

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

Song Weiguo: "..."

Wow!

It’s really great!

A 315-horsepower car to buy groceries, his Audi A6 only has 190 horsepower, he suspects Chen Xing is fooling him.

Up to 315 horsepower, you call this a commuter shopping car?

"It can reach 315 horsepower because we use a permanent magnet synchronous motor. It 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 has a large size, a higher speed limit, and a simple structure. If it is a sports car, it will be the best choice."

"I understand."

Chen Xing silently memorized it.

To put it bluntly, the permanent magnet synchronous motor and the induction asynchronous motor are the former's energy conversion efficiency, that is, the battery life will be high, while the latter pursues the speed limit, the energy conversion efficiency is low, and the battery life will be greatly reduced.

Because Chen Xing's car-making task for Hua Ming is to make a family car, and it is also the first car for young people, how to make good use of limited electricity is the top priority.

Song Weiguo suppressed the shock in his heart and asked: "What is the maximum torque?"

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

For example, an off-road SUV, such as the 2015 Range Rover, has a maximum torque of 600. If an ordinary family car plays tug-of-war with it, it will just be dragged along.

"450N·m."

Hua Ming said the value without hesitation, and then added: "At present, the acceleration from 0 to 100 kilometers is 2.81 seconds."

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

"In the past few days."

Hua Ming replied.

When he got the specific date, Song Weiguo was completely upset. In other words, the 2.81 seconds measured by Linghang 001 was only about 14 degrees.

Don't think that the temperature will not affect the acceleration from 0 to 100 kilometers. 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 will decrease, and it will take longer to reach the expected speed, thus affecting the test results of the acceleration from 0 to 100 kilometers.

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

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

After understanding the complete power, Song Weiguo looked at Chen Xing again, and the shock in his pupils seemed to say: 800V high-voltage platform, 315 horsepower, 450N·m maximum torque, and this 2.81-second 100-kilometer acceleration, are you sure you built a family car?

Feeling that gaze, Chen Xing also felt that his car was a bit abnormal, and looked at Hua Ming and said: "2.81 seconds 100-kilometer acceleration is too fast, not suitable for daily use, try to set a limit to reduce the vehicle performance."

"This is available."

Hua Ming had expected it.

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 modes."

After the voice fell, Ren Guofei, who had been standing aside and had not spoken for a long time, nodded and agreed: "Yes, we have set limits, namely energy saving, daily and sports mode."

"Ahem."

Lei Jun coughed twice, attracting everyone's attention and said: "These three modes, I actually want to change the sports mode to combat mode, which sounds more impressive."

"Combat is good."

Chen Xing nodded slightly and gave affirmation.

Liu Dongzi once said that you should 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 sports mode, it feels very ordinary and can't run fast.

But if it is combat mode, the passion will rise all of a sudden.

Can Linghang 001 fight?

2.81 seconds to accelerate from 0 to 100 km/h in cold weather is already very "combat", faster than Chen Xing's Mercedes-Benz S320.

"Then change 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 the vehicle's power as much as possible and limit the vehicle's maximum horsepower."

"In daily mode, the acceleration from 0 to 100 km/h can also reach 3.1 seconds. Horsepower and torque are also limited to a certain extent to avoid the owner's discomfort and tragedy."

"Combat mode is to release all restrictions, regardless of energy saving issues. The power of the motor, electronic control, and lithium battery will reach the limit value I mentioned above."

"Not bad."

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 also praised.

Automobiles are a field that Longguo has never made a breakthrough in.

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

If Longxing Group really succeeds this time, it will definitely have a strong and colorful chapter in modern history. He dare not imagine whether the history books will give Chen Xing a separate page.

In the past, there were semiconductor chips, communications, fast charging technology, and conquered mobile phones. In the future, there are solid-state batteries and automobile technology. It is not an exaggeration to say that it is the pride of domestic production.

"By the way."

Song Weiguo changed the subject and asked: "After saying so much, can I test drive it to see the quality of our domestic cars."

"This..."

Chen Xing hesitated a little. He looked at Hua Ming, Ren Guofei, and Lei Jun to ask for their opinions.

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

"Chief Song, why don't you let me drive it, because our Linghang 001 has not been sent for quality inspection, and the safety aspect is 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 responsibility even if something goes wrong."

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

Hua Ming said what he was thinking.

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

There are many cases of vehicles losing control. Tesla in Shanghai has lost control many times abroad. No one can guarantee whether a probabilistic event will happen.

"Let me do it."

Chen Xing stood up.

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

Since he said it was okay, it must have been foolproof. Besides, Longxing Heavy Industry of Linghang Automobile has now been transferred to Longxing Group. He is the big boss behind the scenes. He has to experience it himself.

"Don't argue. It's just that it was not sent for a complete test. I know my limits. I was not afraid of driving a tank before. Can I make a big difference in driving a small family car?"

Song Weiguo didn't take the probabilistic event of "possible loss of control" seriously at all. As a veteran who participated in the counterattack, his courage is not comparable to that of ordinary people.

He came to the left side of the 800V Linghang car and opened the door directly...

The next second.

He was stunned again.

"This interior..."

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

"How to drive without a gear lever?" Song Weiguo was stunned.

He is now like a "Sankara" from the countryside, suddenly coming to a bustling metropolis. The towering buildings alone open his eyes and shock his heart.

"Bang——"

The right door opens.

Hua Ming looked at Song Weiguo's stunned look and continued, "Commander Song, you only need to step on the brake to power on. The first button below the center console is a 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. For the P gear, just press the button at the end."

"There is also a mode selection. It is on the console on your left hand side. It is a button with a red warning frame. Press it once for energy-saving mode, and long press 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 shift mode of a sports car. Commander Song is busy with all kinds of things and should not be familiar with this driving mode. Let me demonstrate it first."

"Then... OK."

Song Weiguo was really shocked.

Sure enough, 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 really had never driven such a car.

Chen Xing sat in the main driver's seat, Song Weiguo came to the back seat, and Hua Ming did not hesitate and also sat in the co-pilot seat of the vehicle.

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

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

If this "low probability event" happened, it would be terrible. He had already imagined what would be written on the front page of tomorrow's news.

"Ding Dong--"

Chen Xing stepped on the brake and powered on the vehicle. The dashboard flipped and displayed the current specific values ​​of the vehicle.

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

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

In contrast, the electric car was so quiet that it made people suspect that it did not start successfully.

"You can shift gears."

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 shifts the paddles down while keeping the brakes on.

"Ding!"

The vehicle makes a warning sound.

At the same time, the dashboard also shows that it has been engaged in D gear, which is often called the start gear, or the drive gear.

"Electric cars don't have a clutch. After the president successfully shifts the gear, the vehicle will automatically release the handbrake. You can drive directly now."

"Okay."

Chen Xing tapped the accelerator pedal.

The Pilot 001 began to move forward. Out of caution, he did not say to pull it to the full speed. After all, if the five people in the car got into trouble, the whole Longguo would have to shake.

Even if it was just daily mode, when Chen Xing stepped on the accelerator, he could clearly feel the seat pushing back, and the acceleration was very fast. In the blink of an eye, it reached 60 kilometers per hour. This was when Chen Xing was more 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 needs to meet daily use needs, but we also try to make it take into account the driving pleasure of the owner as much as possible."

"Yes."

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

"I understand." Song Weiguo nodded, then looked ahead and said, "Young friend Chen, try the combat mode. I want to feel the limits of this car in real life."

"No problem."

Chen Xing replied.

"Turn left later. There is a 1,000-meter straight test area over there."

Ren Guofei pointed to a road.

"Got it." 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 area was not long, only 100 meters, but there were also wading, gravel roads, speed bumps, and continuous speed bumps test areas behind, which were very challenging for the vehicle's comprehensive performance.

I don't know whether Chen Xing's driving skills are good or Linghang 001 is indeed strong in comprehensive strength. Even if the road is complicated, the vehicle didn't bump much, and Song Weiguo was secretly amazed.

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

He thought to himself.

After passing the continuous speed bumps, there is a crossroads. To the left is the straight test area, to the right is the uphill and downhill test area, and to the front is the vehicle parking lot.

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

"Ding!"

The vehicle sounded a prompt.

The tail wing in the rear area of ​​the car rose, and the whole car looked nothing like an ordinary family car from the side.

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

The accelerator pedal was pressed.

"Boom--"

The car roared.

"Why is there an engine sound?"

Song Weiguo couldn't help asking.

Isn't it driven by a motor?

How can a motor drive make a sound?

"This is a simulated sound wave. As I said before, we want to add some driving pleasure to 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.

"Hold on tight."

Chen Xing reminded.

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

Seeing this, Song Weiguo was about to say whether he should be so exaggerated, but the sudden strong inertia made him fall back suddenly, and the back of his head came into close contact with the seat.

"Boom--"

The Linghang 001, which stepped on the accelerator pedal, made a roar, like a bullet shot out of a gun, shooting forward at high speed.

"You said this is a family commuter car?"

"Ah??"

Song Weiguo complained in his heart.

He touched the back of his head. Fortunately, he hit the Nappa seat, which was soft enough. If it was the old bus seat, he estimated that the back of his head would hurt for a few minutes.

"This car is quite fast, Chief Song needs to hold on tight." Lei Juns reminded.

The 1,000-meter straight test area passed in a flash, and Chen Xing also gradually braked slowly, finally stopped, and put the parking gear in P.

"How is it?"

Chen Xing looked at Song Weiguo in the back seat.

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

"Chief Song said it's good, then we are relieved, do you want to experience it yourself?" Chen Xing planned to give up the driving seat.

He had just tested it, and the industrial foundation of his own car was still very good, and he also had this confidence.

"Okay, I'll try it."

Song Weiguo was not polite.

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

With a "boom", the vehicle rushed 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, which made Chen Xing and others confused and reminded him.

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

"It's not the problem of no license plate, it's that there is no quality inspection!"

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

"It's okay."

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

His bold move not only embarrassed Chen Xing and others, but also Fengtian's traffic supervision system.

"Captain, captain, come and see, there is a car without a license plate waiting for the traffic light."

Fengtian Traffic Management Bureau.

The police of 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 in my territory? You want to die, right?"

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

He has been in the industry for decades and has never seen this car. It looks a bit like a Porsche, a bit like an Audi, and a bit like a Mercedes-Benz. It is more sharp than their front faces, and the rear wing can be raised. Even the traffic control system can't recognize what kind of car it is.

"Hey, come here and see what kind of car this is. It seems that someone has modified the car and is driving without a license in our jurisdiction."

"What???"

Instantly.

The police from the Fengtian Traffic Control Bureau approached one after another.

When they came to the screen and looked carefully, they shook their heads and said frankly that they didn't know what kind of car it was. It was probably modified.

"Damn, the modified car is so arrogant, immediately send out the team to catch them and bring them in for tea."

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

"Hello, director."

He answered the phone.

The next second, he immediately changed his face and nodded, "Okay, I see, OK, OK, it turned out that our Chief Song and Longxing Group were testing the car together. No wonder he drove so coolly and his driving skills were so charming."

"By the way, director."

After the captain finished speaking, he asked again, "Should we send a team of traffic police to escort? After all, this matter..."

Before he finished speaking, the director on the other end of the phone interrupted him and said, "No, Chief Song has a special plainclothes vehicle."

"Got it."

As the phone hung up, the captain looked at the people who surrounded him. The traffic police also waved his hand and said: "Okay, go back to your posts, it's okay. This is the Longxing Group's test drive, our Fengtian's future pillar enterprise."

"It turned out to be the Longxing Group."

"No wonder I've never seen this car before, it turned out to be an internal test version vehicle."

"Hearing what the captain said, I found that the person in the back seat seemed to be Chen Xing, and Ren Guofei and Lei Jun."

"Oh, it's true!"

...

The people who were still testing on the road didn't know what happened. After strolling around, Song Weiguo drove back to the car production factory.

After getting off the car, he couldn't help but exclaimed: "This car is easy to drive, with enough power, fast acceleration, and the key is that the endurance is high."

Before Chen Xing and others could speak, Song Weiguo added: "I think it can be fully promoted, 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."
