Black technology: I can decompose everything

Chapter 35 Powerful Performance
The switch has not been powered off since it was added, and the power supply is still 200V transformed from 48V through a transformer, plus a current close to 10A.

It can be said that since the motor started running, there has been no change in current and voltage, and the motor has always been in the best output state.

The speed of the motor on the screen is still increasing slowly, and the speed has been increased to 55000 rpm before it begins to decay, and finally until the speed stabilizes at around 53800 rpm.

Seeing the hub motor running into a stable stage, he understood that this is the best running effect of this motor.

Of course, the motor will increase its speed when the current is overloaded to adjust, but that operation is not the most economical, it just increases the speed, and the use of electric energy is actually a waste.

After extremely detailed and rigorous testing, the in-wheel motor he produced now has a final power of 400W, which is 0.6 horsepower when converted into horsepower.

Such a hub motor is enough to handle all electric bicycles in the future, even if it is used on electric motorcycles, this power is enough.

Moreover, if this motor is used in future electric bicycles, it must be weakened to a certain extent, and the final speed of the electric bicycle should be controlled at around 35km/h, which is the most suitable for electric bicycles at this stage.

After obtaining these basic data, the next step is some more detailed tests, such as running at the maximum output power and how long it can run at the maximum. These are all follow-up tests.

And he didn't continue to participate in these. With the basic data of the motor, the energy he invested in the motor can be transferred to other aspects.

The next thing he wants to solve is the battery problem. He needs to find a suitable battery before the product is finalized. Now the most suitable battery for electric bicycles on the market is still lead-acid battery.

The voltage of each section of this battery is 12V. If four sections are installed, it can reach the working voltage of the hub motor he developed, so an electric bicycle needs four sections.

This is the most economical and popular battery at the same time. Although it has various defects, it is still the first choice for electric bicycles.

However, the appearance and specifications of these lead-acid batteries currently on the market do not conform to his design, which requires him to find a partner in advance, and let the partner and him jointly develop a battery that is suitable for electric vehicles.

In fact, he already had an idea in his mind. What he was looking at were the three domestic battery manufacturers that hadn't fully taken off yet, Chaowei, Tianneng, and Camel.

The first two are located in Jiangsu and Zhejiang, which are relatively close to him, but the Luotuo family is located in Jingchu, which is relatively far away geographically. He plans to wait until he can check the results of the college entrance examination. After checking the results, he will take Zhang Dong on the journey.

First go to Jiangsu and Zhejiang to investigate, and then go to Jingchu. In fact, he is inclined to choose camels psychologically, because compared with the three companies, camels are easier to win.

While he was still waiting for the time to check his grades, the phone in his father's office was about to ring off the hook. All the calls were teachers from the admissions offices of various colleges.

In addition to these teachers, the county education director also called him. In fact, they all said one thing, that is, congratulations to his son, that is, Li Zhenhua, for his good grades.

When Li Min'an first received the call, he was actually in a state of confusion. If anyone asked him to tell him something as soon as he came up, they would get no benefit.

This means that phone scams are not popular in this day and age, otherwise he would have to check it out. Of course, as he received more calls later, he also knew the ins and outs of the matter.

In fact, these colleges and universities compete for the source of students every year, especially for the top students, and they spare no effort!

Li Min'an, who had been on the phone all morning, finally felt a little more relaxed at noon, and immediately wanted to escape in front of the phone. He had been eating at the bureau's cafeteria at noon, so he chose to go directly to the factory to find Zhou Meiqin.

When Li Min'an came to the factory, Li Zhenhua and Zhou Meiqin's wife were eating deliciously, and they were puzzled when they saw Li Min'an running away sweating.

"What's wrong with you, there's a tiger chasing you from behind!"

Li Min'an talked all morning, didn't even have time to take a sip of water, picked up Zhou Meiqin's water glass and drank, waited until the water was poured into his stomach, and then answered.

"What kind of tiger is chasing you? There are teachers who are more powerful than tigers, and Xu Bureau of our county education bureau. Our political commissar and director are all looking for me!"

Li Zhenhua was still stuffing stir-fried vegetables into his mouth, but when he heard this, he also looked at Li Min'an curiously.

"Whatever you look at, it's all thanks to you. I haven't done anything serious this morning, and you still have the nerve to sit here and eat?"

Seeing him like this, Li Min'an was very angry and funny, although he said that, but he was very happy in his heart.

His father was addicted to his mouth, but he was handsome for only three seconds, and he was immediately suppressed by Zhou Meiqin. "What's the matter, why are you playing charades with me? If you don't talk about it, you will live in the office tonight!"

Li Min'an immediately wilted like a frost-beaten eggplant, and honestly told Zhou Meiqin what happened in the morning.

Li Zhenhua, who was listening on the sidelines, felt bad. Teachers from various colleges and universities were about to arrive on the battlefield. If his main goal was not to run away, he would be annoyed to death by these teachers later.

Although he still doesn't know how his grades are in the exam, but he knows that his grades will definitely not be bad, so he can have an explanation in front of the old couple.

Run, run now, run immediately, this was the only thought in his mind, and while his parents were still talking, he quietly retreated from the office.

When they came to the purchasing office, they called Zhang Dong who was still eating, and the two went straight to the coach station.

Zhang Dong didn't have enough to eat, so he didn't know, so he took his ID card and the two left according to his instructions.

It wasn't until the two of them got on the long-distance bus to Quancheng that Zhang Dong reacted and asked him: "Manager Li, where are we going? Why did we buy a ticket to Quancheng? The pickup at home can still be used. Let’s drive, let’s drive to Quancheng!”

"Where are we going? Let's go to Jiangsu, Zhejiang, and Jingchu to find suitable batteries there, and strive to take down the battery supply chain on this trip!"

After hearing what he said, Zhang Dong's doubts disappeared a little, but he always felt that this matter was done in a hurry, how could anyone drag him away while he was still eating.

"Okay, but why can't we leave in the afternoon? Is it necessary to leave so hastily? You take me out, does the factory manager know?"

Looking at Li Zhenhua who had a mean smile on his face while speaking, his expression was not good.

"Don't tell me, kid, you dragged me out without telling your mother!"
