Technology overlord starts with new energy vehicles

The low-speed electric vehicle quickly arrived at the parking lot in the factory area.

This is a very large parking area, covering a huge area. The road is a cement road, and it has been planned. Rows of vehicles are neatly parked in the open space that divides the parking spaces.

There are at least 30 rows, and there is a space for traffic in the middle of each row. Many vehicles are parked next to each other, and more than 300 vehicles can be parked in just one row!

A group of people sitting in the sightseeing car can clearly see the many vehicles in the venue.

From a distance, there are at least four to five thousand cars parked in this parking lot, like a sea of ​​cars!

Kyushu low-speed electric vehicles, Kyushu Taishan, Kyushu Dongting, and in addition to electric vehicles, there are many fuel vehicles!

In addition to the four-wheeled carts and small cars, there are rows of two-wheeled electric cars parked under the specially built canopy.

Looking at the scene in front of them, even the old people who have walked past countless factories couldn't help being moved again.

"There are quite a lot of cars here, much more than those parked in the parking lots of those large enterprises I have seen."

"The large number of vehicles proves that the benefits are good. Everyone has spare money to buy a car. The employees of Kyushu Automobile seem to have a very good life."

"You can see the whole picture at a glance. Maybe there are not as many luxury cars parked in some super-large enterprises, but the number of vehicles is far more than those large enterprises."

"I heard before that Kyushu Auto's salary is very good. Compared with other places, the salary is about one-third higher, and the benefits are also very good, and the working hours are not long."

"Well, most of the cars have a small tail plugged in to charge!"

"In this parking lot, at least four-fifths are products of Kyushu Automobile. It seems that Kyushu electric vehicles have the most, followed by Kyushu low-speed electric vehicles, and then fuel vehicles produced by other car companies."

"Low-speed electric vehicles and two-wheeled electric vehicles, there are almost no other brands, which proves that the employees of the company agree with Kyushu Automobile very much."

Seeing these old people, they were once again shocked by the ordinary scene of Kyushu Automobile in front of them, and they all looked like sighing.

Xu Yifan's face could not help showing a little bit of pride. The scenes in front of him were created by him in nearly three years.

Higher benefits, a better working environment, and visible hard work can lead to higher wages.

And the employees who can stay are basically the talents left after selection. Maybe some people are not top-notch, but most of them are more pragmatic and hard-working.

"Jiuzhou Automobile cannot exist today without the joint efforts of all employees and all R\u0026D personnel.

Naturally, it is also necessary to repay the hard work of the employees and give everyone better treatment. This is what Kyushu Automobile should do! "

After the words fell, several old people looked over, and couldn't help admiring this young man who was only in his mid-twenties.

At this age, he has the vision and means that senior managers in their 50s, 60s, or even 60s and 70s don't have, and can manage the company in an orderly manner.

Mr. Xu is not to be underestimated!

The sightseeing vehicles carried the crowd, passed through a large number of car parking areas, and finally came to a location deep in the parking lot.

The number of vehicles here is small, and what can be seen is almost all Kyushu Dongting or Kyushu Taishan.

Behind these vehicles, most of them have a charging pile with a charging gun hanging on each of them.

"This is the charging station in Kyushu Automobile Factory. There are a total of 50 fast charging piles, capable of charging with a maximum power of 80 kilowatts.

It only takes about two hours for the battery to go from zero percent to one hundred percent, and it can accommodate 50 vehicles for charging at the same time. "

The fast charging pile of Kyushu Automobile is similar to the semi-finished products and imagined scenes that several old people have seen.

For these charging piles, after the old man got off the car, he carefully looked around the charging piles.

"This speed can already be used in practice. If it is popularized, the development speed of electric vehicles will be much faster."

"Two hours, I still feel a little bit, but this is a cruising range of 500 kilometers, and the tram will not run out of power, so generally speaking, it will take about one and a half hours."

"I don't know how about the construction cost of such a charging station. It would be better if it was cheaper. How about the construction cost of such a charging station?"

Xu Yifan replied: "Depending on the scale of the charging station, the area and location of the construction, the distance from the main circuit network, etc., the construction cost will also be different.

For example, the charging station in the Jiuzhou Automobile Factory has a construction cost of about two million yuan.

Such a price can be achieved mainly because it is relatively close to the circuit network in the factory area.

At the same time, the self-manufactured charging piles are cheap for civil construction, there is no site rent, and it is more convenient to build at the same time than the construction in the urban area.

If it is in an urban area, the power of the substation and distribution system is not enough, the line network needs to be improved, the cost of civil construction is higher, and the rent of the site, etc., the price needs to be at least doubled, or even several times! "

"The cost is two million, and in some cities the price needs to be doubled, which is about four million, which can realize fast charging of fifty vehicles at the same time."

This price is similar to what these old people have known before, and it is a very huge expense.

A city can satisfy consumers with more than just one charging station. Depending on the size of the city, a charging station with about one or two hundred charging positions in a small county is barely enough.

And slightly larger third-tier and second-tier cities, according to the city's car market, can accommodate at least 500 cars and chargers at the same time. If there are more electric cars in the future, it may be possible to accommodate 5,000 cars at the same time.

As for the first-tier and super-first-tier cities, the vehicle population reaches more than 5 million. Even if one-tenth of the vehicles become electric vehicles, the basic charging facilities that need to be established will reach a very scary amount.

If you want to develop new energy vehicles, the construction of charging piles has to be carried out.

It is precisely because of the large number of constructions that need to be built and the huge amount of money spent that new energy vehicles will start to attract more people's attention from around 2010.

It was not until after 2020, ten years later, that a large number of orders began to break out.

But even before Xu Yifan travels in the future, most of the owners who buy new energy vehicles will choose to buy pure electric vehicles only if they have the conditions to install charging piles at home.

According to the data in 2022, the number of new energy vehicles in the country reached 13.1 million, of which the number of pure electric new energy vehicles was 10.45 million, the number of public basic charging piles was about 1.8 million, and the number of private basic charging facilities was about 3.4 million tower.

The ratio between the number of new energy vehicles and public charging piles reached 7.3:1.

Of course, among those public charging piles, many of them may be slow charging piles, and the construction cost is not comparable to Kyushu's fast charging piles, which are much, much cheaper.

But now several new energy vehicles sold by Kyushu Automobile all support super fast charging. Apart from Kyushu Automobile, there are not many reliable pure electric vehicles on the market.

In such an environment, it is a bit redundant to build slow charging piles.

If all fast charging piles are built, the number of charging piles does not need to be so many.

But even if the ratio reaches 20 new energy vehicles, a fast charging pile will be used together.

According to the pure electric new energy vehicles in 2022, with a population of 10 million, it is necessary to build 500,000 fast charging piles.

According to 4 million to build 50 fast-charging charging stations for Kyushu cars, it will cost a total of funds, and a total of about 40 billion will be invested to complete the construction.

This is based on the ownership of 10 million pure electric new energy vehicles.

But what Xu Yifan wants is not only to sell 10 million units, but to make Kyushu Automobile the first choice for consumers to buy cars in China, and occupy at least eight floors of the market.

According to the same data in 2022, the number of cars in China is 417 million, and it is likely to be about 330 million.

If the charging mode is simply adopted, there is a long way to go for the sales of pure electric vehicles.

At this time, maybe ten years, maybe twenty years later, with the construction and improvement of charging facilities, there will be such an effect.

This is also one of the reasons why Xu Yifan wants to change the battery. Charging and battery replacement have their own advantages and disadvantages, and the combination of the two can improve faster.

Moreover, the current situation is very different from Xu Yifan's previous life. Not all car companies are in their infancy.

Kyushu Automobile, in terms of batteries and motor controllers, has surpassed the new energy vehicle products in the next decade or so.

The emergence of Kyushu Automobile has changed the development process of new energy vehicles. In the early stage of new energy construction, there was a car company with very good technology.

Of course, in addition to pure electricity, you need to start from other aspects, and hybrid is also a good choice.

A group of people looked around the charging pile, and learned more data related to the charging pile with Xu Yifan and others.

After half an hour, he said with satisfaction.

"This charging station is very well built."

"However, Mr. Xu, what does the replacement of the power station you mentioned just now look like?"

Xu Yifan: "It's not far from here to replace the power station, everyone please come with us."

Without even needing to get on the sightseeing bus, Xu Yifan led everyone to walk another hundred meters to the depths of the parking lot.

Ahead, the R\u0026D personnel are still performing functional debugging and collecting more data on this power station facility that has just been developed.

It is said that it is a facility, but it is actually an open space.

A van loaded with battery packs was parked around, and two semi-automatic battery replacement forklifts were placed on the ground.

The staff of the two Kyushu Dongting vehicles took turns to replace the battery packs. After the replacement was completed, they would drive out for a walk and come back to continue waiting for the battery replacement.

From time to time, staff will climb under the car from time to time to check whether the battery pack is installed securely.

Compared with the previous charging piles, some data and the like need to be introduced. Here, Xu Yifan does not need to introduce too much. You only need to look at it to understand what happened.

The van full of batteries, under the control of the staff, the forklift forklift took the battery out of the compartment, and it only took about a minute to quickly install the battery to the bottom of the car in Dongting, Kyushu.

"Change the tram..."

A group of old people watched without blinking until the battery was replaced. The vehicle quickly drove aside to check the stability of the battery, and another car filled the vacant space to replace the battery.

After seeing the battery replacement several times, a group of old people got together and talked about this battery replacement technology.

"Such a power swap system is very smart, perhaps at first glance, the equipment and technology used are relatively simple.

But as long as you observe carefully, you can find many details that are difficult to achieve.

It is not easy to develop such a battery replacement technology, which involves a lot of software and hardware cooperation, which is more complicated than fast charging. "

"Kyushu Automobile has once again given us a big surprise."

"The issue of battery replacement was also discussed before, but in the end it was nothing."

"Grid Li also proposed in 2009 last year that electric new energy vehicles should be based on battery replacement, supplemented by plugging in, centralized charging, and a business model of unified distribution.

At that time, because the conditions were not very mature, it was not successful.

One of them is technology. In the short term, it is difficult to achieve the extreme speed of the Kyushu car battery replacement platform seen now.

The second is the cost of battery replacement. First of all, a car cannot be equipped with only one battery. If a battery replacement station is built, more batteries need to be reserved for battery replacement.

At least 100 pure electric new energy vehicles need 30 batteries to ensure that the batteries can be replaced at any time. How much will the cost of battery replacement be?

Third, the standardization of batteries. The battery models of various car companies are not uniform, and the models cannot be uniformly adapted. It is impossible for every car company to build its own power station.

Fourth, the issue of battery ownership, who owns the battery, how to calculate the electricity bill, how to do private fast charging, how to do battery upgrades, battery depreciation issues, new batteries and old batteries, etc.

Fifth, how to divide the final responsibility for new energy vehicles malfunctioning or spontaneous combustion. "

"Of course, battery replacement is not all disadvantages, and battery replacement is the closest way to replenish energy like gasoline.

First, the biggest advantage is that the energy replenishment is fast, and consumers do not need to wait for several hours for charging.

The second one is high efficiency. One battery swapping station covers an area of ​​4 parking spaces. Compared with a dozen charging stations, the land utilization rate of dozens of parking spaces is higher.

Third, the power swap mode can use the city’s peak and valley power for charging, and the advantages of power distribution are more obvious, improving energy utilization efficiency. It is important to know that power in some periods of time may be wasted in vain. "

"According to predictions, when buying a new car, many people will give up buying electric cars because of charging problems.

Even if super fast charging only takes two hours or even one hour, compared with fuel vehicles, it still has great disadvantages, which is unacceptable to many consumers. "

"And many consumers who do not have charging conditions in their homes may never consider new energy electric vehicles if they do not change their batteries."

A group of old people gathered together to discuss the advantages and disadvantages of battery replacement.

However, this is not the first time such a question has been raised, and no clear result has been drawn before, and there will not even be a clear answer in the next ten years or so.

With such a short time now, naturally there is no reason to discuss for a while.

Seeing that no one had a good idea, Elder Zhou glanced at Xu Yifan next to him, and pulled him into the discussion group.

The old man asked: "Mr. Xu, Kyushu Automobile Company can be said to be the most powerful new energy car company in China today, and it is also an expert focusing on the road of electric vehicles.

Regarding this question, I believe you also have some ideas. Tell me, is it better to replace the battery or charge it? "

Suddenly entering the boss chat group, Xu Yifan was a little confused.

However, he had thought about this question carefully, and said it directly without thinking too much about it.

"Whether it's charging or changing the battery, both have their advantages and disadvantages, and it's not a choice between the two.

I think it is better to leave this issue to consumers to choose. Both technologies must be developed. If you want to charge, you can charge, and if you want to change the battery, just change the battery. "

Seeing that some of them wanted to speak, Xu Yifan waved his hand and said faster.

"I also have some of my own views on the few questions you raised just now, as well as my thoughts on the future development of Kyushu's charging and battery replacement."

"A few questions about battery replacement.

One of them is technology, the other is the cost of battery replacement, the third is the battery standard, the fourth is the ownership of the battery, and the fifth is the operation failure of new energy vehicles. "

"Let me answer them one by one."

"Needless to say the first technical problem, Kyushu Automobile's current semi-automatic battery replacement technology, although not perfect, can still be used barely."

"The second issue is the cost of batteries. If the Kyushu Automobile Factory establishes its own battery replacement company in the future, we will add subsidies to our cars, even if we prepare two batteries for one car.

However, if other car companies want to use our batteries for battery replacement, they may have to pay a battery fee. "

"The third issue is battery standards. I think Kyushu Motors has the ability to set industry standards.

Hengxin Battery Factory can be said to be the company with the best lithium iron phosphate battery technology in the world. The safety and durability of the batteries produced have also withstood the test of nearly two years.

In this regard, it is also somewhat related to the second question.

I want to set up a separate company, which is mainly engaged in the battery replacement business of new energy vehicles, and provides battery replacement services for new energy vehicles manufactured by our company or other car companies.

Of course, if PetroChina, Sinopec, or the power grid are interested, we can also work together to establish an energy company.

Other car companies want to use battery replacement, as long as their interface standards follow the interface standards provided by Kyushu Automobile, and the chassis can accommodate battery packs from Hengxin Battery Factory.

Then the car companies use the battery replacement service, specifically charging a part of the battery reserve fee from the car companies.

It is still free of charge directly, and the fee will be charged from the electricity replacement fee later. This issue is still to be discussed. "

Of course, Xu Yifan still had some things to say.

In today's new energy market, it is more likely that the new energy vehicles of Kyushu Automobile will occupy the absolute mainstream of the market in a short period of time, and there is no need to consider the problems of other new energy vehicle companies.

What other cars, can BYD have the current Kyushu cars? The motor, control system, and battery are all far behind!

Only the Kyushu Motors family builds and replaces power stations at their own home, and the standards must be formulated by their own home.

"The fourth issue is the ownership of the battery, who owns it, how to calculate the electricity bill, how to do private fast charging, how to do battery upgrades, and battery depreciation.

My idea is to sell the car, but not the battery.

The battery that goes with the vehicle belongs to Kyushu Motors, or that newly established energy company.

The battery is gone, so there is no question of who owns it.

In terms of electricity bills, it must be more expensive than charging at home. After all, the operation will continue, and the specific price.

Of course, if you feel like it, there is no problem even using a home charging pile to replenish energy.

Battery depreciation, the battery does not belong to the buyer, so naturally there is no need to worry about depreciation.

In this way, consumers don't have to worry that when new energy vehicles are released in the future, the price will drop sharply due to battery problems. "

"Fifth, accidents caused by batteries, etc. If possible in this regard, I want to buy insurance for batteries, which will be included in the electricity bill, or in the cost of vehicle purchase."

In fact, Xu Yifan feels that such an insurance is almost guaranteed to make money!

From the research and development of battery technology to the establishment of Hengxin Battery Factory, Xu Yifan has always paid great attention to battery safety.

Things like spontaneous combustion, based on the number of more than 10 million Kyushu low-speed electric vehicles in the country today.

Not to mention that there is no case, and there have been several times, but they all occurred in the case of a vehicle accident that caused a violent collision.

However, even though the battery was about to be crushed, there was no violent combustion, allowing the car owner and other nearby vehicles and pedestrians to stay away from the scene calmly.

In normal driving and use, the battery stability has hardly encountered any problems.

"This is my general idea on the development of battery replacement technology in the future. Of course, as I said before, try to take care of all consumers.

The model of replacing power stations and charging stations, and even the hybrid vehicles that Kyushu Auto will have in the future, are all aimed at retaining all consumers, so that they can find suitable vehicle products among Kyushu Auto's products.

Even if it is to replace the power station, a few more parking spaces can be given to build charging stations.

It's just that if there is a replacement power station, fewer charging piles can be built. "

After Xu Yifan's voice fell, the people beside him fell into deep thought for a while.

After a long time, an old man exhaled and said.

"Although there are still some small flaws in the specific details, it is not impossible to do it."

"In terms of specific details, there is still a lot to discuss."

"It is feasible to a certain extent, we can discuss it in detail..."

"Using Kyushu Automobile as a blueprint to formulate the development of domestic new energy vehicles, maybe this can develop faster."

"The charging station and the power station are carried out at the same time, which can take care of two kinds of people at the same time."

"However, if the battery is replaced, the battery does not belong to the consumer, so how to define the issue of new energy subsidies?"

Seeing that everyone was very interested in this method, Xu Yifan smiled and continued.

"By the way, let's talk about a few more advantages. This kind of storage battery can be used to replace electric vehicles. One hundred battery packs can be loaded inside, which can hold a total of 7,000 kilowatt-hours of electricity.

It is not necessary to remove the battery pack from the car when charging, just stop at the charging station and connect the super charging cable, which is very convenient for charging.

At the same time, these batteries can be charged with the valley power at night, which is also one of its advantages.

After all, as long as the valley power is used for charging, it means that the power that may have been charged during the peak power consumption of the user during the day has become the power consumption at night.

This also balances the peak and valley electricity.

In addition to the cost of the battery, its advantage is that the construction cost is very low. There is almost no requirement for the power grid, and the site does not need a particularly large place.

It costs at least tens of thousands of dollars to level the ground, and then the power station can be replaced.

More luxurious, that is, like a gas station, set up a venue for battery replacement.

Even with the addition of a hundred battery packs, the investment in a replacement power station equipment will not exceed six million yuan in total. "

After continuous improvement of the production process of Kyushu Automobile, the lithium iron phosphate produced by the factory is already a relatively cheap lithium battery. If only the cost is counted, about 500 yuan can buy a kilowatt-hour of electricity.

Of course, it is impossible for Kyushu Motors not to make a little money. If it cooperates with the government to open the power station business, it is not too much to sell 800 yuan per kilowatt-hour.

A replacement tram can store 7,000 kilowatt-hours of electricity, which is just over 5 million yuan, which is just a trivial matter for the official!

And in terms of battery cost, Xu Yifan also has a trump card, which is the second-generation sodium-ion battery that is currently being developed.

As long as it is completed, the cost will be further compressed than the lithium iron phosphate battery, and there is no problem in reducing it by double!

"In addition to the above-mentioned advantages, this battery car can also discharge large current and voltage.

When the circuit network fails, it can temporarily supply power to residents within a certain range.

Or when the power consumption is tight, the direction discharge can supplement the power grid.

Even long-distance power transmission is possible, when facing large-scale power outages in cities.

Transport the fully charged electricity from power-rich areas to power outage areas, and prioritize the protection of residents' electricity needs. "

Xu Yifan explained some functions and benefits of changing trams in detail.

After hearing it, several people couldn't help sighing.

"Well, we have to think about it after seeing it."

"It is estimated that we will not be able to go back in the recent period of time."

"This is a good thing, isn't it? From Kyushu Automobile, I see the possibility of rapid development of new energy!"

"I still have to let Lao Li and the others come over, some things need to be discussed with them."

"The charging station and the replacement station should be carried out together, the standard of the battery pack will be unified, and the construction of the replacement network will be established."

"There are still some specific technical aspects that need to be carefully confirmed with Kyushu Automobile."

"By the way, let's discuss the matter of new energy subsidies again. If the intensity remains the same, it is more suitable for Kyushu Automobile Factory."

"Today, I saw too many good things."

"It's getting late in the blink of an eye. I've heard about it before. The food in Kyushu Auto Canteen is delicious."
