After more than a week of market research, the R&D center has investigated the current situation of electric vehicles in China quite clearly. Pen & Fun & Pavilion www.biquge.info

This is especially true for products that have already been put into use.

Although the development of domestic automobile battery technology is slower than that in the time and space before Li Fanyu, because of the special situation in some parts of China, the development of electric buses is not bad.

However, the electric car mentioned here is not a car driven by a battery like BYD, but a supercapacitor bus.

The name supercapacitor is cool, but it's not a new thing. In the seventies and eighties of the last century, this new type of energy storage device has been developed.

But this thing is not actually a "battery" in the traditional sense, but a power supply with special properties between a capacitor and a battery.

The principle is to use the electric double-layer structure composed of activated carbon porous electrode and electrolyte to obtain ultra-large capacity.

The reason why it is called "super" is because the energy is stored in the charge separated from the supercapacitor, and the larger the area used to store the charge, the denser the separated charge, and the larger the capacitance.

Awesome, right?

Actually, it's not great at all.

This thing performs very well in electricity, but it has a fatal heel.

That's ......

It can be big, but not small!

The larger the area where the charge is stored, the denser the separated charge means, which means that the bigger and stronger the thing, but if it is smaller, it will not work.

In short, the stored charge area of a supercapacitor rises, and its capacitance increases exponentially. Conversely, while the stored charge decreases, the capacitance decreases geometrically. At a certain point, the ability to separate charges is not even as good as the volume of lithium batteries.

Another fatal problem is the structure of the electric double layer, which works like a vat with only one side open.

It's easy to pour water in, but it's easier to pour water out!

In other words, a supercapacitor can only be used as a carrier. It can accumulate a large amount of electric charge, but its own power storage capacity is very urgent.

In short, it's very powerful, it's very powerful, but it's very short.

Anthropomorphize it like a muscle coil, the kung fu in bed is top-notch, and you can feel the impact like never before, but it can only last for thirty seconds.

That's right, premature ejaculation is a fatal injury.

If you want to get a sustained pleasure, you can only put a box of kidney treasures next to him. Thirty seconds over, one bottle, thirty seconds over, another bottle......

If you can tolerate this interruption, then it's actually a good bubbler.

That's what it is.

Therefore, the volume requirements of supercapacitors determine that this thing can only be used in large-scale electrical equipment such as buses. And like a smaller car, an electric car, or a mobile phone, don't even think about it.

The limitation of its power storage capacity determines that it is very unfriendly to the irregular, or lack of fixed charging facilities.

That's where the constraints of this thing lie.

However, in the past few years, a city with very developed old trams like Pushi Qingdao faced the problem of difficulty in renovating old tram lines.

The government has asked social enterprises for solutions to this problem.

In this context, the supercapacitor bus came into being.

Because the bus route station is fixed, and the vehicle runs relatively smoothly. Coupled with the large size, it meets all the limitations and requirements of supercapacitors.

Although supercapacitors have fatal shortcomings, they also have many advantages: long life, short charging time, no pollution caused by chemical prescriptions and memory problems of Asahi lithium batteries. In addition, the power released is large due to the large capacitance.

These features are still very suitable for bus use.

At present, some companies on the market, such as Pushi Aowei and Qingdao Bosheng's supercapacitor bus products, have achieved good performance in application.

In fact, the operating methods of these two companies are similar to Li Fanyu's idea of the future infrastructure of Internet vehicles.

Because it was born to solve the difficulty of renovating the old tram line, the two companies, together with the Pushi and Qingdao governments, have made a series of infrastructure improvements.

Based on the renovation of the old tram lines in the past, charging piles are set up every few kilometers to carry out node-type charging with the characteristics of the short charging time of supercapacitor buses.

The old tram lines are fully utilized, and the waste is turned into treasure.

But that's about it.

In other cities where the old tram network is not well developed, it is not worth it, or even thankless, to build electric piles specifically for supercapacitor buses.

Such an environment has limited the development of supercapacitor buses.

When he saw these materials and understood the market situation thoroughly, Li Fanyu was embarrassed.

ay

Think about the time and space before, the BYD......

The progress of society still needs to be driven by strong enterprises.

Without the guy who lost the slag of the car mark, it can be said that the development degree of electric vehicles in this time and space is still a little worse than that of China in the previous time and space.

That's hard.

"Brother Fan, what should we do at this stage? Do we make an electric concept car first, or start the research and development of battery technology first?"

Xu Fufang asked.

Li Fan pondered slightly, and said: "It's better to cooperate with Huawei first and study battery technology." A concept car without technical support is a castle in the air and has no practical significance. Even if we achieve phased results, we can estimate and then apply them according to the technical progress, right?"

Xu Fufang nodded in agreement.

"Also, I will tell the group to allocate a research and development fund. In the past, your group went directly with funds, and we didn't have much foundation in battery technology, so we couldn't let outsiders laugh at us for swinging on cooperative R&D projects. Li Fanyu explained.

Xu Fufang smiled: "Well, okay." ”

After the matter was preliminarily settled, Li Fanyu announced the dismissal of the meeting, and he came to the office of the R&D center.

Locking the doors and windows, he entered the X space directly without saying a word, opened the system panel, and tuned to the lottery page.

"Do you want to use the system right away? Yes/No. ”

Well?

It wasn't until he opened the system panel that he sensed something was wrong.

This lottery is not the same as the previous lottery with the system upgrade!

The previous draw was similar to roulette. It starts with five slots on it, and each time you level up, you get one more.

But now this big draw is what it looks like a slot machine!

In terms of styling alone, it looks a little more high-end than before!

Li Fanyu was a little excited.

I clapped my hands and muttered a word winner, winner, chicken-dinner, and went directly to the start option on the system panel!

With a frantic turn, Li Fanyu's mood was like skipping school to go to an Internet café in junior high school - he could even hear his heart beating in his chest!

As the "slot machine" slowly slowed down, he clenched his fists.

"Come on, come on, come on, come on!"

He is like a gambler who doesn't know what he will get if he wins, and only wants to usher in an unknown surprise.

Finally, under his gaze through the autumn water, the "slot machine" stopped.

"Hint: Congratulations to the current user for obtaining a special item [Random Boost Technology Progress], note: After using this item, you can immediately upgrade the current user's production class and technology class X option, regardless of the level, and directly upgrade to the next technology stage. Is it for immediate use?Yes/No. ”

"Yes!" Li Fan was unaware.

"Hint: The scientific and technological process of the energy laboratory has been upgraded to the third stage, opening up the field of electricity. ”

"it!"
