Chapter 385: An epoch-making product, promoting the charging pile infrastructure construction plan
“There are definitely some highlights, and they are several data of epoch-making significance.” Hua Ming replied to Chen Xing unhurriedly.
Hearing this, Song Weiguo suddenly felt his eyes light up, and quickly asked: "What is it?"
"The whole vehicle is an 800V high-voltage platform."
"800V?"< br>
Song Weiguo was stunned for a moment.
Chen Xing was shocked and secretly sighed: "As expected of a red-quality talent, he actually bypassed the 400V high-voltage platform and directly built an 800V high-voltage platform."
What is high voltage? platform?
To put it simply, it is the voltage standard used 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 voltages of around 800V.
To put it more simply and understandably, the 800V platform is like the "heart" of an electric vehicle, providing it with a stable energy source.
People who exercise regularly will know that the heart beats slower for people who like to exercise than for people who don't. This is because the myocardial contractility increased due to high-intensity training, and the heart ejects more blood each time than normal people. caused.
What is the difference between 400V and 800V high voltage platforms?
The 400V high-voltage platform is equivalent to an ordinary person. After running for two kilometers, he will be out of breath, his heart can’t stop beating wildly, and he has reached the physical limit. But the 800V high-voltage platform, this "athlete" has just come to feel, The body has only warmed up, and this is the difference between the two.
Hua Ming saw Song Weiguo's doubts and explained systematically: "It is the supply voltage of the vehicle. The larger the value, the more powerful the vehicle will be."
"I understand, electric cars, the stronger the energy supply, the more powerful they are."
Song Weiguo responded.
He has an engineering background, and has done some research on these voltages, currents, and mechanical design.
Seeing that Song Weiguo was easy to understand, 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, PTC, DCDC, PDU, MCU, etc., all operate at the limit of 800V. "
"Of course."
Suddenly he changed the topic and continued: "The 800V high-voltage platform is only for our sulfide solid-state batteries. For cars, polymers can only achieve 570V high voltage.”
"Let's get back to the point. In a high-voltage environment of 800V, the motor's horsepower 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 with a look that seemed to ask: Are you sure you are building an ordinary car and not a sports car?
What is the concept of 315 horsepower?
Take Chen Xing’s mobility scooter, the 2014 Mercedes-Benz S320, for example. It has a 3.0TV6 engine with a horsepower of 272 horsepower.
272 horsepower is already the limit of the 2014 Mercedes-Benz S-Class. Even the new 2015 Mercedes-Benz S-Class has only 333 horsepower. Your Pilot 001 has 315 horses?
The most important thing is that the price of the Mercedes-Benz S-Class starts at one million. The car-building plan issued by Linghang Auto and Chen Xing is in the range of 200,000-300,000. The price difference between the two is several times. .
Aware of Song Weiguo's confused gaze, Chen Xing immediately organized his speech and said with a smile: "It would be a good thing to have stronger power and higher horsepower. It can save a lot of time when buying groceries."
Song Weiguo: "..."
Good guy!
What a great guy!
He went shopping for groceries in a 315-horsepower car, while his Audi A6 only had 190 horsepower. He suspected that Chen Xing was deceiving him.
With a maximum power of 315 horsepower, what do you call this a grocery shopping cart?
“We can reach 315 horsepower because we use a permanent magnet synchronous motor, which is smaller in size than an induction asynchronous motor and has higher energy conversion efficiency. It can better adapt to daily use, but the corresponding cost It's also relatively high."
Hua Ming took a breath and continued to explain: "However, 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 It will be the best choice.”
“I understand.”
Chen Xing silently wrote it down.
Permanent magnet synchronous motors and induction asynchronous motors, to put it bluntly, are the former’s energy conversion efficiency, that is, the battery life will be high, while the latter pursues the speed limit, and the energy conversion efficiency is low, and the battery life will be greatly reduced.
Because Chen Xing’s car-making task for Huaming is to make a family car, which 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 "power" of the car. This parameter is useful for scenarios such as rapid acceleration, off-road escape, towing heavy objects, climbing hills, etc. decisive role.
For off-road SUVs, such as the 2015 Land Rover Range Rover, its maximum torque reaches 600, and ordinary family cars can only be towed in a tug-of-war with it.
“450N·m.”
Hua Ming said the value without hesitation, and then added: “For now, the acceleration from 100 kilometers 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 respond.
Song Weiguo lost his composure when he got the specific date. In other words, Pilot 001 measured 2.81 seconds in a weather with a temperature of only about 14 degrees.
Don’t think that the temperature will not affect the acceleration of 100 kilometers. You must know that tires are made of rubber. Rubber will harden in low temperature weather, resulting in reduced elasticity and affecting road grip.
During the acceleration process, the tire elasticity and grip are reduced, and it will take longer to reach the expected speed, thus affecting the test results of 100 kilometers acceleration.
And in low temperature environments, the density of air will also increase.
Song Weiguo has concluded that if tested at normal temperature, that is, around 22 degrees, it is estimated that it can run in 2.7 seconds, or even reach an astonishing 2.6 seconds. After all, its maximum torque has exceeded 450N·m. This is Very scary.
After understanding the complete power, Song Weiguo looked at Chen Xing again, the shock in his pupils seemed to say: 800V high-voltage platform, 315 horsepower, 450N·m maximum torque, and these 2.81 seconds 100 kilometers acceleration, 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 100 kilometers in 2.81 seconds is too fast. It is not suitable for daily use. Set a limit as much as possible. , reducing vehicle performance.”
“This is true.”
Hua Ming had expected it.
He glanced at Rebus and Ren Guofei, and continued: "Boss Lei and Ren have proposed that vehicles should take into account different groups of people, so we have created three modes."
After the words fell, Ren Guofei, who had not spoken for a while, nodded and agreed: "Yes, we have set limits, namely energy saving, daily and sports modes."
"Ahem."
Rebus coughed twice, attracted everyone's attention and said: "Of these three modes, I actually want to change the sports mode to the combat mode, which sounds more majestic."
"The battle is good."< br>
Chen Xing nodded slightly and affirmed.
Liu Dongzi once said, never compare marketing with Rebus.
The moment Rebus said "battle mode", he knew what the marketing genius wanted to focus on.
If it is in sports mode, it feels very average and cannot run fast.
But if it is combat mode, the passion will suddenly rise.
Can Pilot 001 fight?
The acceleration from 100 kilometers in 2.81 seconds in low-temperature weather is already very "combat", faster than Chen Xing's Mercedes-Benz S320.
"Then change it to combat mode." Hua Ming had no special feelings about the name and continued: "In energy-saving mode, our electronic control system will recover as much power as possible from the vehicle and limit the maximum power of the vehicle. Horsepower.”
"In daily mode, acceleration from 100 kilometers to 100 kilometers can reach 3.1 seconds. Horsepower and torque are also limited to a certain extent to prevent car owners from being uncomfortable and causing tragedy."
"Combat mode relaxes all restrictions. Regardless of the energy saving issue, 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 was also impressed.
Automobiles are an area that Longguo has never broken through.
High-end engines, differentials, and corresponding power transmission systems are all relatively dependent on foreign technology.
If the Longxing Group really succeeds this time, modern history will definitely be a highlight. He can't even imagine that the history books will give Chen Xing a separate page.
In the past, there were semiconductor chips, communication fields, and fast charging technology, which conquered mobile phones. Later, there were solid-state batteries and automobile technology. It is really not too much to say that the light of domestic production is strong.
“That’s right.”
Song Weiguo changed the topic and asked: “After talking so much, can you let me take a test drive to see the quality of our domestically produced cars.”
"This..."
Chen Xing hesitated a little. He looked at Hua Ming, Ren Guofei, and Rebus, asking for their opinions.
The vehicle is still being tested in a closed area, and the safety performance is not yet known. 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, because our pilot 001 has not yet been sent for quality inspection, and the safety aspect needs to be studied."
Rebus volunteered.
Ren Guofei waved his hand and also introduced himself: "Let me do it. I watched the assembly and production of this car bit by bit. Even if something happens, I will admit it."
“There will be no problem with the car, please rest assured, because we use an integrated aluminum structure body, plus a closed area, and there are tire walls around it to buffer, which can ensure life safety even at 100 speeds. ”
Hua Ming said what was on his mind.
Test driving the first domestic electric car requires great courage.
There are many cases of vehicles losing control. Tesla has lost control of its vehicles abroad many times. No one can be sure whether the accident will happen.
"I'll do it."
Chen Xing stood up.
With Hua Ming's guarantee, he believed in his red talent.
Since he said yes, he must have done everything absolutely. Besides, Longxing Heavy Industry, which leads the automobile industry, has now been transferred to the Longxing Group. He is the big boss behind the scenes, and he has to personally do whatever it takes. Experience it.
“Don’t argue, it’s just that it hasn’t been submitted for complete testing. I have my own sense of proportion. I wasn’t afraid of driving a tank before. How can I make a difference in a small family car?”< br>
Song Weiguo did not take the probability event of "possible loss of control" at all. As a veteran who had participated in the counterattack, his courage was not comparable to that of ordinary people.
I saw him coming to the left side of the 800V pilot car and opening the door directly...
The next second.
He was stunned again.
"This interior..."
The central control has a large screen, and the seats are ergonomically designed chairs made of Nappa leather. There is no shift lever under the center console, only a few buttons and Storage area.
“How can we drive this without a gear lever?” Song Weiguo was confused.
He is now like a "Shankara" who came from the countryside and suddenly came to a prosperous metropolis. The towering buildings alone opened his eyes and shocked his heart.
“哐——”
The right door opened.
Hua Ming looked at Song Weiguo's dazed look and continued: "Chief Song, you only need to step on the brakes to power on. The first button under the center console is one-touch ignition, and the one on the left side of the steering wheel is There are turn signals, wipers, and a shift paddle on the right side. If you want to shift into drive gear, step on the brake and pull it down to enter the D gear. "
"When driving, you can directly shift it. For P gear, press the button at the end directly. ”
"There is also a mode selection. It is on the console on your left hand side. It has a button with a red warning border. Press it once to enter the energy-saving mode, and press and hold for three seconds to enter the combat mode."
"How about first? Let me drive around." Chen Xing came behind Song Weiguo and continued: "This is the shifting mode of a sports car. Chief Song is busy with many things, so he may not be familiar with this driving mode. Let me demonstrate it first."
"That...okay."
Song Weiguo was really shocked.
Sure enough, if you stay in the army for too long and are not exposed to new things from the outside world, you will be left far behind. He also failed to show off. After all, he has never driven such a car.
Chen Xing got into the driver's seat, Song Weiguo came to the back seat, and Hua Ming also got into the passenger seat without hesitation.
Rebus and Ren Guofei looked at each other and quickly got into the back seat before the vehicle started, which just reached the maximum capacity of five people.
Faced with the suddenly full vehicle, Chen Xing was also a little stressed.
If this was a "low probability event", it would be terrible. He had already figured out what would be written on the front page of the news tomorrow. "Ding dong——"
Chen Xing stepped on the brakes, powered on the vehicle, and the instrument panel flipped over to display 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 a slight vibration in the whole process.
Anyone who has driven a fuel vehicle knows that there is a strong vibration and roar when the engine is started.
Comparing the two, the tram was so quiet that one suspected it had not started successfully.
“You can put it into gear.”
Hua Ming reminded.
Song Weiguo opened his eyes wide and did not dare to miss any details.
As a second-generation rich man who is now a rich man, Chen Xing has played sports cars and is very familiar with paddle shifters. While keeping the brakes firm, gently push down. dial.
“Ding!”
The vehicle made a beep.
At the same time, the instrument panel also showed that it had been shifted into D gear, which is often called the startup gear, or the drive gear.
"Electric vehicles do not have clutches. After the president successfully shifts the gear, the vehicle will automatically release the handbrake. You can just drive now."
"Okay."
Chen Xing tapped the accelerator pedal.
Pilot 001 began to move forward. Out of caution, he did not say to fill up directly. After all, if something happened to the five people in the car, the entire Dragon Kingdom would be shaken.
Even in the daily mode, when Chen Xing stepped on the accelerator, he could clearly feel the seat pushing back, and the acceleration was very fast, reaching the speed of 60 in the blink of an eye. This is still Chen Xing's restraint. case.
“It’s a bit fast.”
Song Weiguo looked at it very carefully.
As soon as he finished speaking, Rebus quickly answered: "It is indeed a bit fast, but as a mobility vehicle, it must not only meet the needs of daily use, but we also try our best to make it Driving pleasure for car owners ”
“Yes.”
Ren Guofei echoed and continued: "Only by taking into account the diversification of uses can our cars be competitive in the market."
"It's understandable." Song Weiguo nodded, then looked forward and said: "Chen Xiaoyou, give it a try In combat mode, I want to actually feel the limits of this car."
"No problem,"
Chen Xing responded.
"Drive to the left later. There is a one-thousand-meter straight test area over there."
Ren Guofei pointed the way.
"I understand." Chen Xing concentrated on driving.
Now they are passing through a circular raised area, and the vehicle is constantly bumping, which is a great test of the vehicle's suspension system.
Fortunately, the road section in the test area is not long, only 100 meters, but there are wading, gravel road, speed bumps, and continuous speed bump test areas behind it, all of which test the overall performance of the vehicle.
I don’t know whether it was Chen Xing who was good at driving, or whether Pilot 001 was really strong overall. No matter how complicated the road surface was, the vehicle didn’t bump very much, and Song Weiguo also secretly said that he was surprised.
"It seems that 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 bump, there is an intersection. If you drive to the left, you will see the straight-line test area. If you drive to the right, you will see the uphill and downhill test areas. If you drive forward, there will be a 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 button for three seconds.
“Ding!”
The vehicle beeps.
The rear wing of the car is raised, and when viewed from the side, the entire car does not look like an ordinary family scooter at all.
As the driver, Chen Xing could clearly feel that the shackles on this beast seemed to have been broken off.
Depress the accelerator pedal.
“Boom——”
The car roared.
"Why is there an engine sound?"
Song Weiguo couldn't help but ask.
Isn’t it motor driven?
Why does the motor drive make noise?
“This is a simulated sound wave. Again, we want to add some driving fun to users.” Rebus quickly explained.
“Yes, simulate the sound wave.”
Hua Ming agreed.
“That’s it.” Song Weiguo has been completely impressed. The intelligence and comfort of the Pilot 001 are much better than his Audi A6. If possible, he would like to replace his car with the Pilot 001.
“Sit tight.”
Chen Xing reminded me.
Ren Guofei and Hua Ming silently grabbed the handle on the upper right side of the vehicle. Rebus was sitting in the middle of the back seat, holding the front seat steady with his hands.
Seeing this scene, Song Weiguo was about to say whether he should be so exaggerated. The sudden strong inertia made him fall backwards, and the back of his head came into close contact with the seat.
"Boom——"
With the accelerator pedal fully pressed, Pilot 001 roared, like a bullet coming out of the chamber, shooting forward at extremely high speed.
"You said this is a family scooter?"
"Huh???"
Song Weiguo complained in his heart.
He touched the back of his head. Fortunately, the seat he hit was a Napa seat, which was soft enough. If it had been the old bus seat, he would probably have had pain on the back of his head for a few minutes.
“This car is very fast, Commander Song must support it well.” Rebus reminded.
The one-thousand-meter straight test area passed in an instant, and Chen Xing gradually braked slowly, finally stopping and shifting into Parking P gear.
"How is 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 will work!"
"Chief Song said yes, then We are relieved, do you want to experience it for yourself?" Chen Xing planned to give up the driving seat.
He has just tested it, and the industrial foundation of his own car is still very good, and he also has this confidence.
"Okay, let me try."
Song Weiguo was not polite.
After the two exchanged seats, Song Weiguo performed a catapult start. The specific operation was to step on the brake and accelerator at the same time, and the words "rocket start" also appeared on the instrument panel.
Just hearing a "boom", the vehicle sped forward quickly.
As an experienced driver, Song Weiguo was very confident. After running through the closed testing area, he drove directly out of the production industrial park. This made Chen Xing and others confused and quickly reminded them.
"Chief Song, the car doesn't have a license plate!"
"It's not the problem of not having a license plate, it's that there isn't even a 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 ahead: “I already have a certain understanding of this car. Now, while there are no cars in the lane, I can help you test it in advance.”
His bold move not only made Chen Xing and others ashamed, but also Fengtian’s traffic supervision system.
"Captain, captain, come and take a look, there is a car without a license plate waiting for the traffic light."
Fengtian Traffic Control Bureau.
The police from the Sky Eye System shouted quickly.
The captain, who originally wanted to take a nap for a while, immediately became energetic after hearing this, and said at the top of his lungs: "What a fool, whoever dares to drive without a license on my territory will risk their life, right?"
Dang He looked carefully and was stunned. He quickly asked: "What kind of car is this?"
He has been working in the industry for decades and has never seen this model. It looks a bit like a Porsche and a bit like an Audi. It's a bit like a Mercedes-Benz, and it's sharper than their front faces. The tail can also raise the tail wing, so even the traffic control system can't identify 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 it without a license in our jurisdiction."
"What???"
In a flash.
Police from Fengtian Traffic Control 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. It was most likely a modified car.
"Damn, the modified cars are so arrogant, I will send out the team immediately to catch them coming in to drink tea."
Just as the captain was about to set off, his cell phone suddenly rang. It was his immediate boss or the biggest boss. The director called.
"Hello Director."
He answered the phone.
The next second, he immediately changed his face, nodded and said: "Okay, I understand, okay, okay, it turns out that it was our leader Song who joined forces with the Longxing Group to test the car. No wonder he drives so coolly and has great driving skills. So charming."
"By the way, Chief."
The captain asked again: "Should we send a traffic police team to escort us?"
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."
"I understand."
As the call was hung up, the team leader looked at the traffic policemen who were surrounding him, waved his hands and said, "Okay, let's all go back to our posts. It's okay. This is the test run of the Longxing Group, our future pillar company in Fengtian."< br>
“It turns out to be Longxing Group.”
“No wonder I haven’t seen this car before. It turns out to be an internal beta vehicle.”
"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 Rebus."
"Hey, it's true!"
...
Everyone who was still on the road test didn’t know what happened. After Song Weiguo walked around for a while, he drove back to the automobile production factory.
After getting off the car, he couldn't help but admire: "This car is easy to drive. It has plenty of power, quick acceleration, and the key is a long battery life."
Not waiting for Chen Xing and others to say anything. , 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 show off, and smiled and said: "That's what you are thinking. Pilot 001's performance in all aspects is very good. If charging piles can be included in the national infrastructure construction project, you can also You can save a lot of money to continue investing in research and development.”
