Automotive Black Technology Chapter 878: : Three-stage X energy laboratory!

www.lnmao.org, the fastest update to the latest chapter of automotive black technology!

After more than a week of market research, the R&D center has clearly examined the current situation of electric vehicles in China.

Especially for products that have been put into application stage.

Although the development of domestic car battery technology is slower than in Li Fanyu's previous time and space, due to the special circumstances in some parts of China, electric buses are developing quite well.

But the electric ones mentioned here are not BYD's battery-driven vehicles, but supercapacitor buses.

Although the name supercapacitor is cool, it is actually nothing new. This new type of energy storage device has been developed in the 1970s and 1980s.

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

The principle is to use a double-layer structure composed of activated carbon porous electrodes and electrolytes to obtain ultra-large capacity.

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

Are you awesome?

Actually, it's not great at all.

The electrical performance of this thing is very good, but it has a fatal weakness.

That's it...

It can be big or small!

The larger the area where charges are stored, the denser the separated charges will be. This means that the bigger the thing is, the more powerful it will be. However, making it smaller will not work.

In short, as the charge storage area of ​​a supercapacitor increases, its capacitance increases exponentially. On the contrary, as the stored charge decreases, the capacitance decreases geometrically. To a certain extent, the ability to separate charges is not even as large as a lithium battery.

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

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

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

In short, it is very powerful, very powerful, but very short.

Anthropomorphizing him is like a strong man with criss-crossed muscles and excellent skills in bed, who can make you feel an unprecedented impact, but can only last for thirty seconds.

Yes, premature **** is a fatal injury.

If you want to get continuous pleasure, you can only place a box of kidney treasures next to him. Thirty seconds is over, one bottle. Thirty seconds is over, one more bottle...

If you can tolerate the interruption, it's actually a good companion.

That's it.

Therefore, the volume requirements of supercapacitors determine that this thing can only be used in large electrical equipment such as buses. As for smaller cars, electric cars, or mobile phones, just don't think about it.

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

This is the limitation of this thing.

However, in the past few years, cities like Ura City Qingdao, where old trams are very developed, faced the problem of difficulty in reconstructing old tram lines.

The government once solicited solutions from social enterprises for this matter.

In this context, supercapacitor buses came into being.

Because the bus routes and stops are fixed and the vehicles run relatively smoothly. Coupled with its 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, and no pollution caused by chemical reactions and memory problems of Asahi lithium batteries. Coupled with the large capacitance, the released power is large.

These features are still very suitable for buses.

Some companies on the market now, such as Pushi Aowei and Qingdao Bosheng's supercapacitor bus products, have already achieved good performance in applications.

In fact, the operating methods of these two companies are similar to Li Fanyu’s ideas about the future Internet car infrastructure.

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

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

Make full use of the old tram lines and turn waste into treasure.

But that’s all.

In other cities where the old tram network is underdeveloped, building electric piles specifically for supercapacitor buses is not worthwhile, or even a thankless task.

Such a general environment has restricted the development of supercapacitor buses.

After seeing this information and having a thorough understanding of the market situation, Li Fanyu sighed.

Hey,

Thinking back to the time and space before, that BYD...

Social progress still needs to be driven by strong enterprises,

Without the guy with the dirty car logo, it can be said that the development level of electric vehicles in this time and space is still a bit worse than that in China in the previous time and space.

This is difficult to do.

"Brother Fan, what should we do at this stage? Should we build an electric concept car first, or should we start developing battery technology first?"

Xu Fufang asked.

Li Fanyu pondered for a moment and then said: "Let's cooperate with Huawei first to study battery technology. A concept car without technical support is just a castle in the air and has no practical significance. Even if we achieve phased results, we can still follow the instructions Technical progress estimation and then application is not? ”

Xu Fufang nodded in agreement.

"Also, I'll tell the group later to allocate a R&D fund. Your group went directly with the funds. We don't have much foundation in battery technology, and we can't let outsiders laugh at us for swinging on a cooperative R&D project. ." Li Fanyu explained.

Xu Fufang smiled: "Yeah, okay."

After initially settling the matter, Li Fanyu announced the adjournment of the meeting and went to the office of the R&D center.

After locking the doors and windows, he entered the X space without saying a word, opened the system panel, and switched to the lottery page.

"Do you want to use the system lottery immediately? Yes/No."

Hmm?

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

This lottery is different from those in previous system upgrades!

The previous lottery was similar to a roulette wheel. There are five grids on it at the beginning, and with each upgrade, the grid increases by one.

But the current big draw looks like a slot machine!

Just in terms of styling, it looks more high-end than before!

Li Fanyu was a little excited.

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

With a burst of crazy rotation, Li Fanyu's mood was like skipping school and going to an Internet cafe in junior high school - he could even hear his heart making a drum-like sound in his chest!

His fists clenched as the slot machine slowed down.

"Come on and do something good! Come on and do something good!"

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

Finally, under his piercing eyes, the "slot machine" stopped.

"Tip: Congratulations to the current user for obtaining the special prop [Random upgrade of technology process]. Description: After using this prop, the current user's production class and technology class X options can be directly upgraded to the next technology, regardless of the level. Stage. Use immediately? ”

"Yes!" Li Fanyu didn't know what to say.

"Tip: The energy laboratory's scientific and technological process has been upgraded to the third stage, opening up the power field."

"Holy shit!"
