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 has been planned. Rows of vehicles are parked neatly in the open space with divided parking spaces.
There are at least thirty rows, and there is a passing space in the middle of each row. Many vehicles are parked close to each other. Just one row can accommodate more than three hundred vehicles!
Sitting in the sightseeing car, a group of people could clearly see the many various vehicles in the venue.
Looking 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 also many fuel vehicles!
In addition to four-wheeled vehicles, there are also rows of two-wheeled electric vehicles parked under specially built awnings.
Looking at the scene in front of them, even the old people who had walked through countless factories couldn't help but be moved again.
"There are so many cars here. There are many more cars parked in the parking lots than in the large enterprises I have seen."
"Having more vehicles proves that the welfare benefits are good. Everyone has enough money to buy a car. The employees of Kyushu Automobile seem to be living a very good life."
"You can tell the whole story at a glance. There may not be as many luxury cars parked in some very large enterprises, but the number of vehicles far exceeds those large enterprises."
"I've heard that Jiuzhou Auto's salary is very good. The salary is about one-third higher than elsewhere. The benefits are also very good and the working hours are not long."
"Well, most cars have a little tail plugged in for charging!"
"At least four-fifths of the products in this parking lot are Kyushu Motors products. It seems that Jiuyuan electric vehicles are the most popular, followed by Kyushu low-speed electric vehicles, and then fuel vehicles produced by other car companies."
"There are almost no other brands of low-speed electric vehicles and two-wheeled electric vehicles, which proves that the company's employees recognize Kyushu Motors very much."
Seeing these old people, they were once again shocked by the ordinary scene of Jiuzhou Automobile in front of them, and they all looked like they were sighing.
Xu Yifan's face couldn't help but reveal a little bit of pride. What he saw before him was a scene he had personally created in nearly three years.
Higher benefits, better working environment, visible hard work can lead to higher wages.
And the employees who can stay are basically the talents who have been selected and retained. Maybe some people are not top-notch, but most of them are more pragmatic and hard-working.
“Jiuzhou Automobile cannot be what it is today without the joint efforts of all employees and all R&D personnel.
Naturally, we must repay the employees for their hard work and give everyone better treatment. This is what Kyushu Motors should do! "
After the words fell, several old people looked over and couldn't help but admire this young man who was only in his mid-twenties.
At this age, he has the vision and means that senior managers in their fifties, sixties, or even sixties and seventies do not have, and can manage the company in an orderly manner.
This Mr. Xu should not be underestimated!
The sightseeing vehicle carried everyone and passed through numerous car parking areas before finally arriving at a location deep in the parking lot.
The number of vehicles here is small, and almost all that can be seen are Kyushu Dongting or Kyushu Taishan.
Behind most of these vehicles, there is a charging pile with a charging gun hanging on each.
"This is the charging station in the Jiuzhou Automobile Factory. There are a total of fifty fast charging piles, capable of charging with a maximum power of 80 kilowatts.
It only takes about two hours at the fastest to charge the battery from zero to 100%, and can accommodate fifty vehicles for charging at the same time. "
Jiuzhou Auto's fast charging piles are similar to the semi-finished products that a few old people have seen and imagined.
Regarding these charging piles, after the old man got off the car, he looked around the charging piles carefully.
"At this speed, it can already be used in practice. If it becomes popular, the development speed of electric vehicles will be much faster."
"Two hours, it still feels a bit long, but this is a cruising range of 500 kilometers, and the tram will not completely run out of power, so generally speaking, it will be enough in about an hour and a half."
"I don't know what the construction cost of such a charging station is like. It would be better if it was cheaper. What is the construction cost of such a charging station?"
Xu Yifan replied: “Depending on the size of the charging station, the construction area and location, the distance from the main circuit network, etc., the construction cost will also be different.
For example, the construction cost of this charging station in the Jiuzhou Automobile Factory is about 2 million.
The reason for such a price is mainly because it is relatively close to the circuit network in the factory area.
At the same time, the charging piles produced by ourselves are cheap in civil construction and there is no site rent. Compared with construction in urban areas, it is more convenient to build them at the same time.
If it is in an urban area, the power of the power transformation and distribution system is not enough, the line network needs to be improved, civil construction costs are higher, and there are also site rentals and other reasons, the required price must be at least doubled, or even several times! "
"The cost is two million. In some cities, the price needs to be doubled, which is about four million. It can realize fast charging of fifty cars 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, one or two hundred charging stations in small counties are barely enough.
Slightly larger third- and second-tier cities, based on the city's car market, can accommodate at least 500 vehicles with chargers at the same time. It is possible that if there are more electric vehicles in the future, it may need to accommodate 5,000 vehicles at the same time.
As for first-tier and super-first-tier cities, the number of vehicles reaches more than five million. Even if one-tenth of the vehicles become electric vehicles, the number of basic charging facilities that need to be established will reach a very terrifying amount.
If we want to develop new energy vehicles, the construction of charging piles must be carried out.
It is precisely because of the large number of construction projects and the huge amount of money spent that new energy vehicles will start to attract more people's attention from about 10 years ago.
It was not until 2020, ten years later, that a large number of orders began to explode.
But even before Xu Yifan time travels in the future, most owners of new energy vehicles will choose to buy pure electric vehicles only if they have charging piles installed at home.
According to 2022 data, the number of new energy vehicles nationwide reached 13.1 million, of which 10.45 million were pure electric new energy vehicles. The number of public basic charging piles was approximately 1.8 million, and the number of private basic charging facilities was approximately 3.4 million. tower.
The ratio between the number of new energy vehicles and public charging piles is 7.3:1.
Of course, many of those public charging piles may be slow charging piles, and the construction cost is not comparable to Jiuzhou Automobile's fast charging charging piles, and is much cheaper.
But now, several new energy vehicles sold by Kyushu Automobile support super fast charging. Apart from Kyushu Automobile, there are not many reliable pure electric vehicles on the market.
In such an environment, building slow charging piles is a bit redundant.
If all fast charging piles are built, the number of charging piles does not need to be that many.
But even if the proportion reaches 20 new energy vehicles, they all use one fast charging pile.
According to the number of pure electric new energy vehicles in 2022, if there are 10 million of them, 500,000 fast charging piles will need to be built.
According to the total cost of establishing 50 Jiuzhou automobile fast charging charging stations based on 4 million, a total investment of about 40 billion is required to complete the construction.
This is based on the inventory of 10 million pure electric new energy vehicles.
But what Xu Yifan wants is not just to sell 10 million units, but to make Kyushu Automobile the first choice for consumers to buy cars in China and capture at least eight levels of the market.
The same data for 2022 shows that China's car ownership is 417 million vehicles, and the 80% is about 330 million vehicles.
If the charging mode is simply used, there is still a long way to go before the sales volume of pure electric vehicles can be achieved.
This time, maybe ten, 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 do battery swapping. Charging and battery swapping have their own advantages and disadvantages. Only by combining the two can they improve faster.
Moreover, the current situation is very different from the situation in Xu Yifan's previous life. Not almost all car companies are in their infancy.
Kyushu Automobile has surpassed new energy vehicle products in the next ten years in terms of batteries and motor controllers.
The emergence of Jiuzhou Auto has changed the development process of new energy vehicles. In the early days of new energy construction, there was a car company with very capable technology.
Of course, in addition to pure electricity, you also need to start from other aspects, and hybrid is also a good choice.
The 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."
"But Mr. Xu, what does the battery swap station you just mentioned look like?"
Xu Yifan: "The battery swapping station is not far from here. Please come with us."
No need to get on the sightseeing bus, Xu Yifan led everyone to walk a hundred meters deeper into the parking lot.
Ahead, the R&D personnel are still debugging the functions of this recently completed power swap station facility and collecting more data.
It's said to be a facility, but it's actually just an open space.
Parked nearby was a van loaded with battery packs, and two semi-automatic battery-swapping forklifts on the ground.
The staff of two Jiuzhou Dongting cars took turns replacing the battery packs. After the replacement was completed, they would drive out for a walk and then come back to wait for the battery replacement.
From time to time, staff will climb under the car to check whether the battery pack is securely installed.
Compared with the previous charging piles that required introducing some data and the like, Xu Yifan does not need to introduce too much here. You only need to take a look to understand what is going on.
Under the control of employees, a battery-swapping forklift took out the batteries from the van filled with batteries. It only took about a minute to quickly install the batteries into the bottom of the vehicle in Dongting, Jiuzhou.
"Change the train..."
The old people watched without blinking until the battery was replaced. The vehicle quickly drove aside to check the stability of the battery, and another vehicle filled the gap to replace the battery.
After watching the battery replacement several times, a group of old people gathered together and talked about this battery replacement technology.
“Such a power swap system is very smart. At first glance, the equipment and technology used may seem relatively simple.
But as long as you look carefully, you can find many details that are difficult to achieve.
It is not easy to develop such power-swapping technology. It involves a lot of software and hardware, which is more complicated than fast charging. "
"Jiuzhou Automobile gave us a big surprise again."
"The issue of battery replacement was also discussed before, but in the end it was nothing."
"Lao Li from the power grid also proposed in 2009 that electric new energy vehicles should be based on battery swapping, supplemented by plug-in, centralized charging, and unified distribution business model.
At that time, it was not successful because the conditions were not very mature.
One of them is technology. In the short term, it will be difficult to achieve the extreme speed of the Jiuzhou Automobile battery swap platform seen now.
The second is the cost of battery swapping. First of all, a car cannot be equipped with only one battery. If a battery swap station is built, more batteries need to be reserved for battery swapping.
At least 100 pure electric new energy vehicles require thirty batteries to ensure that the batteries can be replaced at any time. How much will the battery cost of a battery replacement station be?
Third, regarding 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 establish its own battery swap station.
Fourth, the issue of battery ownership, who owns the battery, how to calculate the electricity bill, what to do with private fast charging, what to do with battery upgrades, battery depreciation issues, new batteries and old batteries, etc.
Fifth, if a new energy vehicle malfunctions or spontaneously ignites, how should the final responsibilities be divided? "
"Of course, replacing electricity is not all disadvantages. Replacing electric vehicles is the closest way to replenishing energy like gasoline.
First, the biggest advantage is that energy replenishment is fast and consumers do not need to wait for several hours for charging.
Second, it is highly efficient. A battery swapping station only occupies 4 parking spaces. Compared with dozens of charging stations, dozens of parking spaces have a higher land utilization rate.
Third, the battery swap mode can use the city’s peak and valley power for charging, which has more obvious advantages in power distribution and improves energy utilization efficiency. You must know that the power in some periods may be wasted. "
“According to predictions, when buying new cars, 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 of charging, compared with fuel vehicles, there are still major shortcomings, which many consumers cannot accept. "
"And many consumers who do not have charging facilities at home may never consider new energy electric vehicles if they do not replace their batteries."
A group of old people gathered together to discuss, each analyzing the pros and cons of battery replacement.
However, this is not the first time that such a question has been raised. A clear result has not been obtained before, and there will not be a clear answer even in the next ten years.
In such a short time now, naturally we can't come up with a solution at the moment.
Seeing that no one had a good idea, Mr. Zhou glanced at Xu Yifan next to him and pulled him into the discussion group.
The old man asked: "Mr. Xu, Jiuzhou Automobile Company can be said to be the most powerful new energy vehicle company in China today, and it is also an expert focusing on the path of electric vehicles.
Regarding this issue, I believe you also have some ideas. Can you tell me, is it better to replace the battery or charge it? "
Suddenly entering the big boss chat group, Xu Yifan was a little confused.
However, he had thought about this question carefully and spoke directly without thinking too much.
“Whether it’s charging or replacing batteries, they all have their advantages and disadvantages, and it’s not a matter of choosing one or the other.
I think it is better to leave this issue to consumers. Both technologies must be developed. Those who want to charge can charge, and those who want to swap can just swap. "
Seeing that some of the people wanted to speak, Xu Yifan waved his hand and spoke faster.
"I also have some of my own opinions on the questions you just raised, as well as my thoughts on the future development of Jiuzhou Automobile in terms of charging and battery swapping."
"A few questions about battery replacement.
One of them is technology, the other is the cost of battery replacement, the standard of battery three, the ownership of battery four, and the operation failure of new energy vehicles. "
"I'll answer them one by one."
"Needless to say, the first technical issue is that Kyushu Motor's current semi-automatic battery swapping technology is not perfect, but it can be used for a while."
"The second issue is battery cost. If Jiuzhou Automobile Factory sets up its own battery replacement company in the future, with subsidies for our cars, even one car can have two batteries.
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 Jiuzhou Automobile today has the ability to formulate 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 it produces have also withstood the test of the past two years.
In this regard, it is slightly related to the second question.
I want to set up a separate company, mainly engaged in the battery swapping business of new energy vehicles, to provide battery swapping business 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.
If other car companies want to use battery swapping, as long as their interface standards comply with the interface standards provided by Jiuzhou Automobile, and the chassis can accommodate the battery packs from Hengxin Battery Factory, it will be fine.
Then the car company uses the battery swap service, which specifically charges a portion of the battery reserve fee from the car company.
Or should it be free directly, and the fee will be charged from the power replacement fee later? This issue remains to be discussed. "
Of course, Xu Yifan still had something to say.
In today's new energy market, it is more likely that Kyushu Motor's new energy vehicles 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 and the current Jiuzhou Auto sell? The motor, control system, and battery are all far behind!
Only Jiuzhou Automobile builds its own battery swap station, and the standards must be set by its own company.
“The fourth question is about the ownership of the battery, who owns it, how to calculate the electricity bill, what to do about private fast charging, what to do about battery upgrades, and battery depreciation issues.
My idea is to sell cars, but not batteries.
The battery matched with the vehicle belongs to Kyushu Motors or the newly established energy company.
The batteries are gone, so there is no question of who owns them.
If you calculate the electricity bill, it will definitely be more expensive than charging it at home. After all, it still needs to be operated, so the specific price is.
Of course, if you feel comfortable, there is no problem even using a home charging pile to recharge.
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 about the price of new energy vehicles falling sharply due to battery problems when used cars are sold in the future. "
"Fifth, accidents caused by batteries, etc. If possible, I would like to buy insurance for the battery and count it in the electricity bill or the cost of vehicle purchase."
In fact, Xu Yifan feels that such insurance is almost guaranteed to make a profit!
From the research and development of battery technology to the establishment of Hengxin Battery Factory, Xu Yifan has paid great attention to battery safety issues.
Things like spontaneous combustion, considering that there are now more than 10 million Kyushu low-speed electric vehicles in the country.
There has not been one case, but there have been several, but they all occurred when vehicles were involved in traffic accidents, resulting in violent collisions.
However, even though the battery was almost crushed, there was no violent combustion, allowing the car owner and other nearby vehicles and pedestrians to calmly stay away from the scene.
During normal driving and use, I have almost never encountered any problems with battery stability.
"This is my general idea about the future development of battery replacement technology. Of course, as I said before, I will try my best to take care of all consumers.
The model that combines battery swapping stations and charging stations, and even the hybrid cars that Kyushu Motors will launch in the future, are all designed to retain all consumers so that they can find the vehicle products that suit them among Kyushu Motors' products.
Even if it is a battery swap station, a few more parking spaces can be allocated to build charging stations.
But if there are battery swapping stations, fewer charging piles can be built. "
After Xu Yifan finished speaking, everyone beside him fell into deep thought.
After a long time, an old man exhaled and said.
"Although there are still some minor flaws in the specific details, it is not impossible to achieve."
"In terms of specific details, there are still many things that need to be discussed."
"It is feasible to a certain extent and we can discuss it in detail..."
"Using Kyushu Automobile as a model to formulate domestic new energy vehicle development, maybe this can develop faster."
"Charging stations and battery swapping stations are carried out at the same time, and they can cater to both groups of people."
"However, if the battery is replaced and the battery does not belong to the consumer, how should the issue of new energy subsidies be defined?"
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 battery-storage car can be loaded with one hundred battery packs, which can hold a total of seven thousand kilowatt-hours of electricity.
When charging, you do not need to remove the battery pack from the car. You only need to park it at the recharge station and connect the super charger. Charging is very convenient.
At the same time, these batteries can be charged using off-peak power at night, which is one of its advantages.
After all, as long as the off-peak power is used for charging, it means that the power that may have been charged by the user during the peak power consumption period during the day has become the power used at night.
This also balances the peak and valley electricity.
In addition to the battery cost, its advantage is that the construction cost is very low, there are almost no requirements for the power grid, and the site does not need to be particularly large.
For a minimum of tens of thousands of yuan, the ground can be leveled and the battery swapping station can start working.
The more luxurious one is similar to a gas station, where a place is set up to exchange electricity.
Even if one hundred battery packs are added, the total investment in equipment for a battery swap station will not exceed 6 million yuan. "
After Jiuzhou Automobile's continuous improvement of production technology, the lithium iron phosphate produced by the factory is now a relatively cheap lithium battery. If you only count the cost, you can buy one kilowatt hour of electricity for about 500 yuan.
Of course, it is impossible for Jiuzhou Automobile not to make a little profit. If it cooperates with the government to open a power station business, selling electricity for 800 yuan per kilowatt hour is not too much.
A tram can store 7,000 kilowatt-hours of electricity, which is just over 5 million yuan, which is just a trivial matter to the officials!
And in terms of battery cost, Xu Yifan also has a trump card, which is the second-generation sodium-ion battery currently developed.
As long as this is completed, the cost will be further reduced than that of lithium iron phosphate batteries, and there is no problem if it is doubled!
“In addition to the above-mentioned advantages, this battery car can also discharge large current and voltage.
When the circuit network fails, power can be temporarily provided to residents within a certain range.
Or when power consumption is tight, direct discharge can be used to replenish the power grid.
Even long-distance power transmission is possible, when facing large-scale power outages in cities.
Transport fully charged electricity from power-rich areas to blackout areas to prioritize residents’ electricity needs. "
Xu Yifan explained in detail some of the functions and benefits of tram replacement.
After hearing this, several people couldn't help but sigh.
"Well, after seeing this, we have to think about it carefully."
"I guess we won't be able to go back these days."
"This is a good thing, isn't it? From Jiuzhou Automobile, I see the possibility of rapid development of new energy!"
"We still need to ask Lao Li and the others to come over. There are some things that we need to discuss with them."
"Charging stations and battery swapping stations should work together to unify the standards of battery packs and build a battery swapping network."
"There are still some specific technical aspects that need to be carefully confirmed with Kyushu Motors."
"By the way, let's discuss the new energy subsidy. As long as the intensity remains unchanged, it will be more suitable for Jiuzhou Automobile Factory."
"I saw so many good things today."
"It's getting late in the blink of an eye. I've heard before that the food in the Jiuzhou Auto Canteen is delicious."
