Ge Xiaotian ceremoniously 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, your wheelchair?"

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

Another engineer stepped forward and wondered as he observed, "Strange, what kind of battery is this, what kind of shape is it!"

"It's not a battery, it's a battery pack!" other engineers gathered around.

The engineer who ran up first opened the protective box and "hissed...... It's an ordinary lithium-ion battery?"

"Not a power battery?!"

"According to this method of use, the heat dissipation is far less than that of a single one, and if the temperature continues to rise, it will cause the SEI film on the surface of the lithium battery anode to decompose, which will cause an exothermic reaction!"

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

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

"it!"

Listening to a group of people discussing, Ge Xiaotian stood up directly.

No wonder!

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

No wonder I'm always scared every time I sit on this thing!

Mmp！

What about building toy cars?

Press the ...... for the master's wheelchair

Ge Xiaotian looked back at the battery pack that had been removed, the corners of his mouth twitched, and there were nearly 100 lithium-ion batteries piled together!

Nearly a hundred!

If it does explode, it's almost the equivalent of hanging a firecracker under your butt......

God is explosion-proof!

Moreover, there are various horizontal and vertical lines on it, like a mess of wool.

What's more, there is also a transparent hose like snakeskin, which looks like there is liquid in it!

What the hell?

"Where's Lao Hong?!"

"Boss, Lao Hong has run away!" a certain Tianwei replied loudly, pointing to the old man running into the wilderness in the distance.

"Get 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 sent Chen Feng a wheelchair, you hadn't gone abroad yet!"

"......" Lao Hong was speechless.

"Come on, send me these two or five boys to Mi-26, a kilometer bungee jump!"

"Don't, boss! Physics, junior high school physics! Let's believe in science!" Lao Hong quickly picked up the battery pack, "series connection increases voltage, parallel connection increases current, combine with each other, first parallel and then series, or first series and then parallel, six strings and four parallel, the size is too large, it is best to be two strings and three parallel, and then two strings and two parallels, and then form an array, so as to produce capacitance and electrical energy far beyond the single battery can provide, to take the simplest example...... 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!"

"Sockets, Household Appliances ......"

"Battery instance!"

"Uh......" Lao Hong was dumbfounded.

"Heh, really be my three-year-old?"

"No, boss, you have to believe me!" Lao Hong stepped forward and whispered, "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 to the side, "Actually, the battery array is not important, what matters is the coolant in the plastic tube, the battery pack management system that is being manufactured, and the remote fault handling system!"

"Huh?" Ge Xiaotian sounded a little familiar.

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

Hearing this, Ge Xiaotian's mind flashed.

He thought of the Tesla battery pack.

Of course, there is a gap between the two, and now this one in my hand can only be said to be a prototype, and it is not 18650.

To put it simply, 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 cells need to be connected in series into a string of 48V, and 10 groups in parallel are 700x10=7AH, a total of 400 batteries, and the capacity is equal to the capacity of ordinary batteries, that is, 48V7AH, with a range of about 20km.

In addition, in order to avoid problems such as overcharge, overdischarge, and overheating of the battery, Lao Hong added voltage stabilizers, coolants, and so on.

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

As for the cost......

Millennium, two dollars for a rechargeable battery, four hundred knots, eight hundred!

As long as the brain is normal, it is estimated that 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, so it is better to use lead-acid batteries." ”

Lao Hong was a little unconvinced, "We have a R&D department, as long as we make a battery pack management system, we can not only control the battery charging and discharging, but also remotely monitor the battery status, even if the explosion-proof chip and exothermic valve all fail, we can also isolate the 'single' failed battery at the first time to avoid fire." Moreover, the capacity of this type of battery pack far exceeds that of lead-acid batteries, and the maintenance cost is extremely low. ”

"It takes money to develop a battery management system, and it's not cheap to produce lithium-ion rechargeable batteries. If the 18650 is taken in large quantities and put on the car...... I'm afraid that except for the rich, no one can afford it at all. The other engineer shook his head in the same way.

In the face of the argument between the two parties, Ge Xiaotian didn't care at all, and sat aside to study carefully.

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

In particular, after knowing that he couldn't fight N mouths with one mouth, he directly brought in dozens of scientific researchers.

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

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

In the end, the donkey's head is not the horse's tail, and each says its own ......

"Lao Hong, it's okay!" Stopping the gushing old man, Ge Xiaotian looked at the manufacturer's delegation, "Let everyone laugh, the atmosphere of our company is relatively relaxed, let's talk!"

............

Stepping into the multi-purpose media room, the Publicity Manager has prepared the required materials and turned on the projector.

It's all about scientific research, so there's no need to dwell too much.

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

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

"Oh?" the representatives of the Beate manufacturers all sat up straight.

"I believe everyone knows that the oil price shock occurred at the beginning of this year, and we won't say more about the details, anyway, oil will definitely be used less and less, and the more expensive it is!"

The crowd all nodded.

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

The crowd continued to nod.

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

In the early 90s, automakers began to redesign the field, such as GM's impact, Ford's calcium-sulfur electromagnetic Ecostar, Wajima's nickel-metal hydride battery RAV4LEV, and Renault's Clio, and this year major automakers have released hybrids again.

I feel like it's an opportunity!"

Hulala......

The purpose of the delegation of Beatty manufacturers is to participate in the construction of cars, and now Ge 10 billion said that he must want to seek cooperation!

Good signs!

All applauded.

And feeling that the other party agrees with his own point of view, Ge Xiaotian is also very happy, "In order to ensure the profit of our project, I hereby did a survey, according to reliable data, in 98 years, the production of electric vehicles in Huaxia was only 50,000 units, and last year it reached 500,000 units, this ten-fold growth rate is simply crazy!"

The delegation of "???" Beati manufacturers was stunned.

Does our Huaxia Automobile Factory build electric cars?

Why don't we know?

"I have calculated, if we now rely on the production line of Tiancheng Chamber of Commerce bicycles, motorcycles, machinery factories, manufacturing frames, plastic parts, shock absorption, controllers, motors, plus your battery technology, you can immediately assemble electric vehicles in batches, millennium, sales of one million is not a problem, next year, sales of two million is very easy, the year after next is expected to exceed five million, and wait until three years later, domestic sales plus exports, annual income of 10 billion is not a dream!"

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

"That's right!"

"Aren't you building an electric car?"

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

"Forehead ......"

"How good is the battery car? The energy consumption is only one-eighth of that of a motorcycle, one-twelfth of a car, and it occupies less than one-twentieth of a private car, and then from the perspective of the development trend, the motorcycle needs to be licensed? What about electric bicycles? For office workers, public transportation is not omnipotent, and cars cannot afford to buy, an electric bicycle can undoubtedly solve many problems! Moreover, we sanitation and property also need electric three-wheelers! When we make money for two years, we have the ability to apply electric technology to the public transportation system, and we have a natural bus! After that, is it still difficult to learn to walk and run, and build new energy private cars?"

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

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

The representatives of the manufacturer were stunned for a long time, and the supervisor stood up again, "I'm sorry Mr. Ge, wait a minute, I'll make a call to the chairman." ”

..................

The delegation of BYD manufacturers came and went quickly.

The general manager's office of the Auto Trade City.

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

"Yes, unless they have enough funds to buy the car factory now, and then verify what I said, there is indeed no sales market for electric cars in Huaxia at present!

Ge Xiaotian is very confident.

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

Even he, with a car, has replaced no less than five cars one after another.

If the BYD manufacturers can reduce the price of the battery, reach cooperation with the large and small manufacturers of the Tiancheng Chamber of Commerce, and rely on a few lightweight, honest, or delicate shapes designed by him, it will be popular all over the country in a year!

The members of the Chamber of Commerce have new projects to make money, the output of BYD batteries has increased again, and Tianheng Auto Trade, which is assembled and sold, will also have enough funds to feed 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, go back and let the Propaganda Department contact the members of the Chamber of Commerce and make a charter!"

"No problem!" Lao Hong patted his chest and turned his voice, "In fact, for us, the most suitable is the battery pack, the maintenance price is low, the electric capacity is high, the volume and quality are relatively small, if the battery management system is developed, it is definitely ...... than the lead-acid battery when applied in construction machinery."

"Have you heard of lithium power batteries? The one that was just launched in North America last month!"

"Nope!"

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

"Compared to nickel-cadmium batteries?"

"Cadmium, that thing is poisonous!"

"That's right, boss!" Lao Hong seemed to think of something, "The battery will be handed over to Beati in advance, and we have to talk about the remote control system!"

"What's wrong?"

"Now that the model has been made, should you, as the boss, go over and motivate the new employees?"

"Oh, so fast, go!"

............

After the mechanical 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 common place, which requires both private cars and agricultural machinery to be repaired, and the area is naturally very vast.

It is connected to Hongtu Automobile Trade in the south and Linyang tractor sales center in the north, with a length of about 100 meters and a width of 100 meters.

There are maintenance sheds on both sides, and a debugging lane in the middle, so even if the remote control research room is moved over, there are hundreds of more people, and it does not seem crowded.

Coming to the steel structure hall, it has been cleaned up and hundreds of computers have been 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 hackers who have been poached.

Some people are typing code, 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 half is made of transparent glass, the lower half is a vending machine-like throughput box, and there is a control platform in the middle, which is divided into two joysticks......

Through the glass, there is a ...... inside

"Damn, isn't this a crane machine?!"

"Huh, boss, have you seen that?"

Ge Xiaotian hesitated, these days, is there a crane machine in the world?

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

"It's just a parallel moving model, and later we're going to add an array camera or a steerable omnidirectional camera to the paws and transplant the joystick into the viewable controller. ”

Once the operator is familiar with how to control the claw with just the handle, the next step is to transplant the claw to a remote-controlled wireless helicopter developed by another department to form a 3D stereo control mode. ”

"It's a hassle to say, you need to add a lot of sensors, gyroscopes, spirit levels, rangefinders, altitude restrictions, range restrictions, automatic return to home, etc., and the handle function will also increase and increase. ”

"Taking it a step further, the manufacture of all-terrain miniature tracked vehicles, diving vehicles, and climbing vehicles can become pipeline detectors, underwater detectors, aerial measuring instruments, and so on. ”

Lao Hong pushed Ge Xiaotian to another experimental area as if offering a treasure, "It is actually very simple to study claws, but we are engaged in engineering, only grasping and releasing them, and it is difficult to meet the needs of all aspects, so we plan to study semi-automatic robotic arms, loading drills, crushers, and punching machines...... Fortunately, there are many semi-automatic and automatic production lines at home and abroad, and it is easy to achieve the expected goals by buying a set of equipment imitation and improvement. ”

"When all these technologies are mature, they can be applied to large excavators, bulldozers, rock drills and other construction machinery, but because the operation is becoming more and more complicated, we will change the handle to a computer. ”

"In the future, our construction site, such as the diving drill bit, the high-voltage leakage area processing line, the high-altitude hoisting manual adjustment, the tunnel excavation, and even the emergency rescue, can use this kind of remote control machinery!"

Ge Xiaotian stared at the iron cabinet a little distracted.

It's no wonder that few companies are willing to engage in R&D.

Listening to Lao Hong's brief introduction, it seems simple, but in fact, each step costs a lot of experiments, and experiments cost money.

It's good that there are results.

If there is no result, the project fails, and the company's funds are wasted, and the company goes bankrupt.

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

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

"Huh?"

"Let the manufacturer of rag dolls make some fun puppets, design a coin dispenser, and then install a few colorful lights that follow the changes of the music inside and outside the tin cabinet, and use animated wallpapers such as cat and mouse, Okuman, etc., and ......"
