Building madman

Ge Xiaotian grandly received the Biyadi factory delegation in the Auto Trade City.

However, I had just chatted with the other team leader. When I turned to the meeting room, an engineer in the team suddenly ran behind him, "Boss Ge, are you in a wheelchair?"

"What's the matter?" Ge Xiaotian was somewhat inexplicable.

Another engineer leaned forward, observing, and wondering: "Strange, what kind of battery is this, it's in a strange shape!"

"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 and said, "His... 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 worse than that of a single branch. If the temperature continues to rise, it will cause the SEI film on the negative electrode surface of the lithium battery to decompose, which will cause an exothermic reaction!"

"The temperature inside and outside is rising at the same time. With only the protection chip and no battery management system, a fire is very likely to occur..."

"A fire is not terrible. The terrible thing is that so many batteries are piled up and burned and will explode!"

"Fuck!"

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

No wonder!

No wonder the boy Takamatsu mentioned the word "explosion-proof" more than once when he introduced the wheelchair, and even patted his chest to ensure that there would be no explosion!

No wonder every time I sit on this thing, I am always worried!

Mmp!

How about building a toy car?

Press the wheelchair...

Ge Xiaotian looked back at the dismantled battery pack, his mouth twitched, and there were nearly a hundred lithium-ion batteries stacked together!

Nearly a hundred!

If it really explodes, it's almost equivalent to putting firecrackers under the butt...

God is explosion-proof!

In addition, the various lines above are like a mess of wool.

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

What the hell?

"Where is Old Hong?!"

"Boss, Lao Hong ran away!" A certain Tianwei pointed at the old man who ran into the wilderness 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 wrong, when you gave Chen Feng a wheelchair, you hadn't gone abroad yet!"

"..." Old Hong was speechless.

"Come on, give me a Mi-26 for these twenty-five boys, kilometer bungee jumping!"

"Don’t, boss! Physics, junior high school physics! Let’s believe in science!" Old Hong Fei quickly picked up the battery pack. The size is too large in series and four in parallel, preferably two in series and three in parallel, and then two in series and two in parallel, and then form an array, which produces much more capacitance and electric energy than a single battery can provide. Take the simplest example... flashlight ,remote control!"

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

"Power strips, household appliances..."

"Battery example!"

"Um..." Old Hong was dumbfounded.

"Oh, really when I am three years old?"

"No, boss, you have to believe me!" Old Hong leaned forward and whispered 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, as well as the battery pack management system that is rushing to manufacture, and the remote fault handling system!"

"Huh?" Ge Xiaotian sounded familiar.

"It's a pity that we don't have that much money for research and development, otherwise we can install it in a car now..."

Hearing this, Ge Xiaotian's mind flashed.

He thought of the Tesla battery pack.

Of course, there is a gap between the two. Now this one can only be said to be a prototype, and the 18650 is not used.

Simply put, Lao Hong's idea is similar to driving an electric car with rechargeable batteries.

Assuming that the voltage of an ordinary rechargeable battery is 1.2V, 40 cells need to be connected in series to form a string of 48V, and 10 sets in parallel are 700x10=7AH, a total of 400 cells, the capacity is the same as that of a general battery, namely 48V7AH, and the stroke is about 20km.

In addition, in order to avoid problems such as overcharging, overdischarging, and overheating of the battery, Lao Hong added a voltage stabilizer, coolant and so on.

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

As for the cost...

In the new millennium, a rechargeable battery costs two yuan, 400 knots, 800 yuan!

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

The surrounding engineers understood the principle of the battery pack and sighed and shook their heads, "The cost is too high, the charging is too slow, and the stability is too poor. It is not as cost-effective as using lead-acid batteries."

Lao Hong was a little unconvinced, "We have a R&D department. As long as we build a battery pack management system, it can not only control the battery charging and discharging, but also remotely monitor the battery status. Even if the explosion-proof chip and the heat release valve all fail, it can be the first time. Isolate "single-cell" failed batteries to avoid fire. Moreover, the capacity of this type of battery pack far exceeds that of lead-acid batteries, and maintenance costs are extremely low."

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

Facing the dispute between the two parties, Ge Xiaotian didn't care, 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 one mouth could not open N mouth, dozens of scientific researchers were directly attracted.

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

Fighting over and over, even pulled out a remote-controlled aircraft...

In the end, the donkey's head was wrong with the horsetail, and each said its own...

"Lao Hong, let's do it!" Ge Xiaotian stopped the chattering old man, and looked at the factory delegation, "Let you laugh, our company atmosphere is more relaxed, let's go, let's talk inside!"

…………

Stepping into the multifunctional media room, the propaganda manager has prepared the required materials and turned on the projector.

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

After serving tea and coffee, Ge Xiaotian picked up the laser pointer when everyone was seated.

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

"Oh?" All representatives of the Biyadi factory sat up straight.

"I believe everyone is aware of the great oil price shock that occurred at the beginning of this year. I won't say more about the details. Anyway, the less oil is used, the more expensive it is!"

A group of people all nodded.

"This year, Huaxia has vigorously rectified the environmental pollution problem, and has also made corresponding subsidies for new energy."

Everyone continued to nod their heads.

"Electric-powered vehicles first appeared at the end of the last century. Later, they were no different from steam engines and internal combustion engines. Only because of battery technology and cost, they have been dormant until now.

In the early 1990s, car manufacturers have begun to design this field again, such as GM’s impact, Ford’s calcium-sulfur electromagnetic Ecostar, Washima’s Ni-MH battery RAV4LEV, and Renault’s Clio. This year, major car manufacturers The hybrid car was released again.

I feel like an opportunity!"

Hula la...

The purpose of the Biyadi factory delegation is to participate in car building. Now Ge Baiyi's meaning is definitely to seek cooperation!

Good sign!

All applaud.

And 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 made a survey. According to reliable data, in 1998, China’s electric vehicle output was only 50,000, but last year it reached Half a million vehicles, this tenfold growth rate is simply crazy!"

"???" The Biyadi factory delegation all brushed together.

Does China Huaxia Automobile Factory make electric cars?

Why don't we know?

"I have calculated that if we now rely on the production lines of the Tiancheng Chamber of Commerce bicycles, motorcycles, and machinery factories to manufacture frames, plastic parts, shock absorbers, controllers, motors, and your battery technology, we can immediately assemble electric vehicles in batches. In the new millennium, it is not a problem to sell one million vehicles. Next year, it will be easy to sell two million vehicles. It is expected to exceed five million in the next year. After three years, domestic sales and exports will make it not a dream to make 10 billion a year! "

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

"Yes indeed!"

"Not making electric cars?"

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

"amount……"

"How good is a battery car? The energy consumption is only one-eighth of that of a motorcycle, and one-twelfth of that of a car, and it takes up less than one-twentieth of a private car. From the perspective of development trends, motorcycles need Get the license? How about electric bicycles? For office workers, public transportation is not a panacea, and cars can't be bought. An electric bicycle can undoubtedly solve many problems! Moreover, we also need electric three-wheelers for sanitation and property! Wait for us to earn two Years of money will be able to apply electric technology to the public transportation system. We have a public transportation system! After that, will it be difficult to build a new energy private car?"

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

There are men, there are women, there are scooters of old age, there are dump trucks, there are...

The factory representatives were dumbfounded for a long time, and the supervisor stood up again, "Sorry Mr. Ge, you can wait a moment, I'll call the chairman."

………………

The Biyadi factory delegation came quickly and left quickly.

General Manager's Office of Qimao City.

Old 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, China does not currently have a sales market for electric cars! Moreover, our plan is to use their own batteries, can it? Heartbeat?"

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 less than five cars one after another.

If the Biyadi manufacturer can lower the price of the battery and reach a cooperation with the big and small manufacturers of the Tiancheng Chamber of Commerce, relying on his design of several lightweight, simple, or delicate shapes, it will be popular all over the country in one year!

Chamber of Commerce members have new profitable projects. The output of BYD batteries has increased again, and Tianheng Automobile Trading, which is an assembly and sales company, will also have enough funds to feed Tiancheng in just one or two years. No one has a reason to refuse.

"This matter belongs to your Machinery Department and Tianheng Automobile Trading. Go back and ask the Propaganda Department to contact the members of the Chamber of Commerce and make a charter!"

"No problem!" Lao Hong patted his chest, and said, "In fact, for us, the most suitable battery pack is the low maintenance price, high capacity, relatively small size and quality. If you develop a battery management The system, used in construction machinery, is definitely better than lead-acid batteries..."

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

"No!"

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

"Compared with nickel-cadmium batteries?"

"Cadmium? That thing is poisonous!"

"By the way, the boss!" Old Hong seemed to think of something, "Give the battery to Biyadi in advance, let's talk about the remote control system!"

"what happened?"

"The model has been made. As a boss, should you motivate and motivate new employees in the past?"

"Oh? So fast? 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 automobile trade vehicle maintenance department.

The three auto trade cities share the same place, both private cars and agricultural machinery need to be repaired, and the area is naturally very large.

It is connected to Hongtu Automobile Trade in the south and Linyang Tractor Sales Center in the north. It is about one kilometer long and 100 meters wide.

There are maintenance sheds on both sides, and the debugging lane in the middle. Even if the remote control research room is moved over, there are hundreds of holes, and it doesn't appear crowded.

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

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

In addition to North American researchers, there are also the "millennium bug group" and more than a dozen hackers that have been dug up.

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

Turn right to enter the test area, and a rectangular iron cabinet that has been erected comes into view.

On the outward side, the upper half is transparent glass, and the lower half is a throughput box similar to a vending machine. There is a control platform in the middle, and there are two joysticks on the left and right...

Through the glass, there is a...

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

"Huh? Boss, have you met?"

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

Lao Hong was a little excited and didn't think carefully about why the boss was surprised. "The most important thing is the motherboard and the track for moving the paws on it, and the rocker on the bottom. One controls the front, back, left and right directions, and the other controls the rotation..."

"This is just a model of parallel movement. Later, we will add an array camera or a steerable omni-directional camera to the paw, and transplant the joystick into the visual handle."

"After the operator is familiar with the method of controlling the paws with only the handle, the next step is to transplant the paws to the remote control wireless helicopter developed by another department to form a 3D control mode."

"It's very troublesome to say, it needs to add many sensors, gyroscopes, level meters, rangefinders, height limits, range limits, automatic return to home, etc., and the function of the handle will also increase and increase."

"Furthermore, by manufacturing all-terrain mini-track vehicles, submersible vehicles, and climbing vehicles, they can become pipeline detectors, underwater detectors, high-altitude measuring instruments, and so on."

Lao Hong pushed Ge Xiaotian to another experimental area like a treasure. "The study of claws is actually very simple, but we are engaged in engineering. It is difficult to meet the needs of all aspects, so we plan to study semi-automatic robotic arms. , Loading drill bits, crushers, punching machines... Fortunately, there are already many semi-automatic and automatic production lines at home and abroad. If you buy a set of equipment to imitate and improve, you can easily achieve the desired goal.

"When all these technologies are mature, they can be used in construction machinery such as large excavators, bulldozers, rock drills, etc. However, as the operations become more and more complex, we will change the handles to computers."

"In the future, our construction sites, such as diving drill bits, high-voltage leakage area processing cables, high-altitude hoisting manual adjustments, tunnel excavation, and even emergency rescue, can all use this kind of remote control machinery!"

Ge Xiaotian stared at the tin cabinet a little distractedly.

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

Listening to Lao Hong's brief introduction of these, it seems simple, but each step requires a lot of experimentation, and the experiment costs money.

It's good to have results.

No results, project failure, at least a waste of enterprise funds, at worst, the enterprise goes bankrupt.

And if the R&D ends here, turn this tin cabinet into a claw machine...

"Old Hong, I think you can make money with this project now!"

"Ok?"

"Let the manufacturer of dolls make some fun dolls, design a coin-operated device, install a few colorful lights that change with the music inside and outside the tin cabinet, and then paste cats, mice, and magpies on the tin cabinet. Animated wallpapers of Tuman and Sakuragi..."
