Build Madness

Ge Xiaotian solemnly received the delegation of BYD manufacturers in the Auto Trade City.

However, just after chatting with the other team leader, when he turned to go to the conference room, an engineer in the team suddenly ran behind him, "Boss Ge, what wheelchair do you have?"

"What's wrong?" Ge Xiaotian was a little puzzled.

Another engineer stepped forward, observed, and wondered: "Strange, what kind of battery is this, the shape is so strange!"

"It's not a battery, it should be a battery pack!" Other engineers gathered around.

The engineer who ran up first opened the protective box, "Hiss...it turned out to be an ordinary lithium-ion battery?"

"Not a power battery?!"

"According to this method of use, the heat dissipation is far inferior to that of a single cell. If the temperature continues to rise, it will cause the SEI film on the surface of the negative electrode of the lithium battery to decompose, which will trigger an exothermic reaction!"

"The internal and external temperatures are rising at the same time. There is only a protection chip, and there is no battery pack management system. There is a high possibility of fire..."

"It's not terrible to have a fire. What's terrible is that so many batteries are piled up and burned together, and they will explode!"

"Fuck!"

Hearing a group of people talking, Ge Xiaotian stood up directly.

No wonder!

No wonder that kid Gao Song mentioned the word "explosion-proof" more than once when he introduced the wheelchair, and even patted his chest to promise: it will never explode!

No wonder I always feel nervous every time I sit on this thing!

Mmp!

What about building toy cars?

Press the wheelchair for my grandpa...

Ge Xiaotian looked back at the removed battery pack, the corners of his mouth twitched, there were nearly a hundred lithium-ion batteries piled up together!

Nearly a hundred!

If it really explodes, it is almost equivalent to hanging firecrackers under the buttocks...

God is so explosion-proof!

Moreover, there are all kinds of lines on it, like a mess of wool.

What's even more ridiculous is that there is also a transparent hose like snakeskin. It seems that there is liquid in it!

What the hell?

"Where's Old Hong?!"

"Boss, Lao Hong has run away!" A certain Tianwei pointed to the old man running towards the wilderness in the distance, and replied loudly.

"Catch me back!"

"Boss, I didn't make the wheelchair, really, I was abroad during that time, you know!!!"

"Hehe, if I'm not mistaken, when you gave Chen Feng the wheelchair, you hadn't left the country yet!"

"..." Lao Hong was speechless.

"Come on, send these two or five boys to the Mi-26, a thousand-meter bungee jump!"

"Don't, boss! Physics, junior high school physics! Let's believe in science!" Lao Hong quickly picked up the battery pack, "Increase the voltage in series, increase the current in parallel, combine each other, first in parallel and then in series, or first in series and then in parallel, six Four series in parallel, the size is too large, it is best to use two series in three parallels, and then two series in two parallels, and then form an array, so as to generate capacitance and power far beyond what a single battery can provide. To give the simplest example... a flashlight ,remote control!"

"In addition to this thing in your arms, you can give me another example of the application of parallel batteries on power equipment!"

"Socket strips, household appliances..."

"Battery instance!"

"Eh..." Lao Hong was dumbfounded.

"Heh, do you really think I am a three-year-old child?"

"No, boss, you have to trust me!" Old Hong leaned forward and said quietly, "You still owe me 30 million Franklin, how dare I blow you up?"

"It sounds reasonable, but it always feels weird!"

"You think too much!" Lao Hong pushed Ge Xiaotian aside, "Actually, the battery array is not important, what is important is the coolant in the plastic tube, the battery pack management system, and the remote fault handling system that are being produced!"

"Huh?" Ge Xiaotian sounded familiar.

"It's a pity that we don't have so much money for research and development, otherwise it can be installed on cars now..."

Hearing this, a light flashed in Ge Xiaotian's mind.

He thought of the Tesla battery pack.

Of course, there are some gaps between the two. The one in hand can only be said to be a prototype, and the one used is not 18650.

Simply put, Lao Hong's idea is similar to using rechargeable batteries to drive electric vehicles.

Assuming that the voltage of ordinary rechargeable batteries is 1.2V, 40 batteries need to be connected in series to form a string of 48V, and 10 sets of batteries connected in parallel are 700x10=7AH. There are 400 batteries in total, and the capacity is equal to that of ordinary batteries, that is, 48V7AH.

Moreover, in order to avoid problems such as battery overcharging, overdischarging, and overheating, Lao Hong added voltage stabilizers, coolant, etc. respectively.

However, the most important thing about the battery pack is the battery management system, otherwise his wheelchair would not be able to charge for eight hours, and could only run for half an hour.

As for the cost...

In the millennium, a rechargeable battery costs two yuan, four hundred, eight hundred!

As long as the mind is normal, no one will buy this wheelchair.

The engineers around understood the principle of the battery pack, sighed and shook their heads, "The cost is too high, the charging is too slow, and the stability is too poor. It is better to use lead-acid batteries."

Lao Hong was a little unconvinced, "We have a research and development department. As long as we make a battery pack management system, it can not only control the charging and discharging of the battery, but also remotely monitor the battery status. Isolate 'single-cell' failed batteries to avoid fires. Plus, these battery packs have a much higher capacity than lead-acid batteries and are extremely cheap to repair."

"Development of a battery management system requires funds, and the production of lithium-ion rechargeable batteries is not cheap. If 18650 is used in large quantities and placed in cars...I am afraid that no one can afford it except the rich." Another engineer also shook his head.

Facing the dispute between the two parties, Ge Xiaotian didn't care at all, and sat aside to study hard.

Although Lao Hong's main business is machinery, he is also very good at electrical equipment.

In particular, after knowing that he could not fight N mouths with one mouth, he directly attracted dozens of scientific researchers.

The engineer on the other side talked about the popularization of civilian use, and the old guy yelled at industrial special machinery.

Fighting back and forth, even pulling out a remote control plane...

In the end, the donkey's head was not in line with the ponytail, and everyone said their own things...

"Old Hong, that's enough!" Ge Xiaotian stopped the chattering old man, and looked at the manufacturer's delegation, "I made everyone laugh, our company has a relatively relaxed atmosphere, let's go, let's chat inside!"

…………

Stepping into the multi-functional media room, the manager of the publicity department has prepared the required materials and turned on the projector.

They are all engaged in scientific research, so there is no need to talk too much.

Serving tea and coffee, and waiting for everyone to sit down, Ge Xiaotian picked up the laser pointer.

"I have a plan to make a fortune about new energy sources. I wonder if you are interested?"

"Oh?" The BYD factory representatives all sat up straight.

"I believe everyone is aware of the big oil price shock that occurred at the beginning of this year. I won't go into details about the details. Anyway, oil will definitely be used less and less, and the more it is used, the more expensive it is!"

A group of people all nodded.

"This year, China has made great efforts to rectify the environmental pollution problem, and has also made corresponding subsidies for new energy sources."

Everyone continued to nod.

"Electric vehicles first appeared at the end of the last century, and later they were on par with steam engines and internal combustion engines. Only because of battery technology and cost, they have remained dormant until now.

In the early 1990s, automobile manufacturers have begun to redesign this field, such as GM’s impact, Ford’s calcium-sulfur electromagnetic Ecostar, Wajima’s nickel-metal hydride battery RAV4LEV, and Renault’s Clio. A hybrid was released again.

I feel like an opportunity! "

hula la...

The purpose of the BYAD factory delegation is to participate in car manufacturing. What Ge Baiyi said now must be to seek cooperation!

Good sign!

All applaud.

Feeling that the other party agrees with his point of view, Ge Xiaotian is also very happy, "In order to ensure the profit of our project, I hereby conducted a survey. According to reliable data, in 1998, the output of Huaxia's electric vehicles was only 50,000, but last year it reached 50,000. 500,000 units, this tenfold growth rate is crazy!"

"???" The delegation of the BYD manufacturer froze for a moment.

Does our Huaxia Automobile Factory make electric cars?

Why don't we know?

"I have calculated that if we rely on the production lines of bicycles, motorcycles, and machinery factories of Tiancheng Chamber of Commerce to manufacture frames, plastic parts, shock absorbers, controllers, motors, and add your company's battery technology, we can immediately mass-assemble electric vehicles. Cars, in the millennium, selling one million cars is not a problem. Next year, it will be easy to sell two million cars, and it is expected to break through five million cars in the year after. And after three years, domestic sales plus exports, annual income of tens of billions is not a dream! "

"Wait!" The manufacturer representative stood up directly, "Boss Ge, are you planning to invest in electric bicycles?"

"yes!"

"Not building electric cars?"

"Do you think there is currently a market for electric cars in China?"

"Forehead……"

"How good is the battery car? The energy consumption is only one-eighth of that of a motorcycle, one-twelfth of that of a car, and the space occupied is less than one-twentieth of that of a private car. From the perspective of development trends, motorcycles need What about electric bicycles? For commuters, public transportation is not a panacea, and cars cannot be afforded. An electric bicycle can undoubtedly solve many problems! Moreover, we also need electric three-wheelers for sanitation and property management! Let’s earn two We have the ability to apply electric technology to the public transportation system with only a few years’ money, and we have public transportation in Tiancheng! After that, is it difficult to build a new energy private car after learning to walk and run?”

After Ge Xiaotian finished speaking, he showed the concept map of the battery car he designed.

There are men, there are women, there are elderly scooters, there are dump trucks, there are...

The representatives of the manufacturer were dumbfounded for a long time, and the supervisor stood up again, "I'm sorry Mr. Ge, please wait a moment, I will call the chairman."

………………

The BYAD factory delegation came and left quickly.

Auto Trade City General Manager Office.

Lao Hong was a little skeptical, "Boss, will they agree?"

"Yes, unless they have enough funds to buy a car factory now, and then verify what I said, there is indeed no electric car sales market in China at present! Moreover, our plan uses the batteries produced by their family. Exciting?"

Ge Xiaotian is very confident.

In another time and space, where are there no battery cars in the streets?

Even if he had a car, he replaced no fewer than five cars one after another.

If the BYAD manufacturer can reduce the price of the battery, reach a cooperation with the large and small manufacturers of the Tiancheng Chamber of Commerce, and rely on his design of a few lightweight, simple, or elegant shapes, it will be popular all over the country within a year!

Members of the chamber of commerce have new lucrative projects, BYD battery production has increased again, and Tianheng Auto Trade, which assembles and sells, will have enough funds to repay Tiancheng in just one or two years, and no one has any reason to refuse.

"This matter belongs to your machinery department and Tianheng Automobile Trade. Let the publicity department contact the members of the chamber of commerce and make a charter later!"

"No problem!" Lao Hong patted his chest, and changed his voice, "Actually, for us, the most suitable battery pack is low maintenance price, high capacity, relatively small in size and quality, if we develop a battery management The system, applied in construction machinery, is definitely better than lead-acid batteries..."

"Have you heard of lithium-powered batteries? The one just launched in North America last month!"

"without!"

"Think of a way to buy one and come back for research. I remember the specific name, it should be called lithium iron phosphate battery!"

"Compared to NiCd batteries?"

"Cadmium? That thing is poisonous!"

"By the way, boss!" Lao Hong seemed to think of something, "Leave the battery to BYD in advance, we have to talk about the remote control system!"

"What's wrong?"

"The model has been made. As the boss, shouldn't you motivate the new employees in the past?"

"Oh? So fast? Let's go!"

…………

After the Machinery Department was evacuated from Xingyue Bay, most of the personnel were divided into various projects, and the headquarters was moved to the Auto Trade Vehicle Maintenance Department.

The three auto trade cities share a place where they not only need to repair private cars, but also repair agricultural machinery, so the area is naturally very vast.

It is connected to Hongtu Automobile Trade Center in the south and Linyang Tractor Sales Center in the north, with a length of about one kilometer and a width of up to 100 meters.

There are maintenance sheds on both sides, and the debugging driveway in the middle. Even if the remote control laboratory moves here, there will be hundreds more people, and it will not look crowded.

When I came to the steel structure hall, it had been cleaned up and hundreds of computers were arranged.

On the left is the office area, and on the right is the test area.

In addition to North American researchers, there is also the 'Millennium Bug Team' and a dozen or so hackers dug here.

Some people are typing codes, some are modeling, some are discussing integrated circuits...

Turn right into the test area, and a rectangular iron cabinet standing up comes into view.

On the outward side, the upper part is transparent glass, the lower part is a throughput box similar to a vending machine, and there is a control platform in the middle, which is divided into left and right joysticks...

Through the glass, there is a...

"Fuck, isn't this a claw machine?!"

"Huh? Boss, have you seen it?"

Ge Xiaotian hesitated. Are there claw machines in the world these days?

Lao Hong was a little excited, and didn't think carefully why the boss was surprised. "The most important thing about this thing is the main board and the track for moving the claws on the top, and the joystick on the bottom. One controls the direction of front, rear, left, and right, and the other controls the rotation..."

"This is just a model of parallel movement. In the later stage, we will add an array camera or a steerable omnidirectional camera to the paw, and transplant the joystick into the visual handle."

"When the operator is familiar with the method of controlling the claw with only the handle, the next step is to transplant the claw to a remote-controlled wireless helicopter developed by another department to form a 3D three-dimensional control mode."

"It's very troublesome to say. It needs to add many sensors, gyroscopes, level meters, range finders, altitude restrictions, range restrictions, automatic return, etc., and the handle functions will also increase and increase."

"Going one step further, manufacturing all-terrain miniature crawler vehicles, diving vehicles, and climbing vehicles can become pipeline detectors, underwater detectors, high-altitude measuring instruments, and so on."

Like offering a treasure, Lao Hong pushed Ge Xiaotian to another experimental area, "Researching claws is actually very simple, but we are engaged in engineering, and it is only limited to grasping and releasing, which is difficult to meet various needs, so we plan to study semi-automatic robotic arms. , loading drill bits, pulverizers, punching machines... Fortunately, there are already many semi-automatic and automatic production lines at home and abroad, and it is easy to achieve the desired goal by buying a set of equipment to imitate and improve."

"When all these technologies are mature, they can be applied to construction machinery such as large excavators, bulldozers, rock drills, etc. However, as the operation becomes more and more complicated, we will change the handle to a computer."

"In the future, our construction sites can use this kind of remote control machinery, such as diving to fish for drill bits, handling cables in high-voltage leakage areas, manual adjustment of high-altitude hoisting, tunnel excavation, and even emergency rescue!"

Ge Xiaotian was a little distracted staring at the tin cabinet.

No wonder few companies are willing to engage in research and development.

Listening to what Lao Hong briefly introduced, it seems simple, but in fact every step requires a lot of experiments, and experiments cost money.

It's good to have results.

If there is no result, the project will fail, ranging from waste of corporate funds to corporate bankruptcy.

And if the research and development ends here, make this metal cabinet into a claw machine...

"Old Hong, I think your project can make money now!"

"Um?"

"Let the doll manufacturer make some fun dolls, design a coin acceptor, install a few bright lights that change with the music inside and outside the tin cabinet, and then paste cat and mouse, Ottoman, etc. on the tin cabinet. Animated wallpapers such as Tuman and Sakuragi..."
