In the first battery factory, the people on Master Wang's side have not yet gotten off work.

The previous battery was really a copycat, and it looked exactly the same as Yufeng's classic battery on the outside, but the internal structure was completely different.

The quality is poor, the line is messy, and the most important thing is that if it is not found to be a copycat, it is very likely to cause an explosion if it is short-circuited and discharged in the previous way, which is really a big mistake.

Master Wang wiped his sweat, pondered again, and discussed it with Xiaoyuan.

Only then did he know that Xiao Yuanshan didn't see it from the outside, but he could see the clues from the internal structure after opening it.

She has a natural sensitivity to circuits and wires, and can peek into the leopard and know a little.

Coupled with her professional studies in school, she is more proficient in judging this aspect than Master Wang.

So next, Master Wang handed over all the work of this link to her, but he still stared at her to do it, in case something went wrong.

But from beginning to end, Madoka didn't get carried away because of the heavy responsibility, her eyes were focused, her expression was cautious, and there was even some excitement in her eyes.

Master Wang stood next to him, looked at the battery, then at Xiaoyuan, and shook his head approvingly.

-

Not far away, Sister Hu answered the phone while watching the movement here.

She frowned with some dissatisfaction: "Who told you that Chang Eryuan is not happy here, I think she is very happy like a fish in water." Why, we are not as noble as your R&D center, so what are you arranging people to do here, and don't let people say that you arranged it. ”

What was said over there, Sister Hu smiled. "Okay, I know it all in my heart, the little girl is very smart. But you, how to arrange the dormitory in the first phase, the college students over there will definitely not be able to stand it. ”

In an office of the R&D center in the night, Yu Jinyi frowned slightly, "I don't know about this matter, I'll deal with it." ”

"The little girl didn't complain to me, she just chatted." Sister Hu was quite thorough, and then joked, "I said Yu Gong, your father is older than me and shouts Sister Hu, what about you, a child, you have always called Sister Hu, and you should call Auntie according to your generation." As an elder who watched you grow up, I am qualified to ask you, what is the matter with you and this little girl? Is this a deliberate toss-up? I'm telling you, it's not fun to chase girls. ”

Yu Jinyi was slightly stunned and smiled, "It's not chasing girls, in fact, I don't know her yet." ”

Sister Hu raised her eyebrows.

Yu Jinyi said slowly: "In a few days, maybe I will have to trouble Aunt Hu to introduce me." ”

-

Sister Hu hung up the phone speechlessly, walked to Chang Eryuan, who was about to get off work, and stopped her. "Chang Eryuan."

Chang Eryuan stood still, somewhat flattered to look at Sister Hu who approached her.

Why does she have a supervisor to pick her up and drop off from work, it's embarrassing. However, as soon as Sister Hu opened her mouth, she was stunned. "Chang Eryuan, do you want to go to the R&D center for an internship, I heard that your classmates are all there."

Sister Hu continued: "I have been in the factory for so many years, it has a little relationship, if you want to go, I can just say hello, and it will be regarded as a reward for you to find a copycat battery today." ”

To be honest, if Sister Hu had made this suggestion yesterday, Xiaoyuan might have really cheekily asked someone to help her transfer to the R&D center, but after a day and a half, she had a different idea.

Madoka decisively refused: "No, I think it's good here!" There are a lot of things I've only seen in books before, and the actual contact feels completely different, and there are a lot of things to gain. ”

She has a feeling that she can also find a good dissertation direction here. She seems to have a little clue, but she hasn't quite caught it yet, so she's going to stay!

The corners of Sister Hu's mouth slowly bloomed with a smile: "Then you can continue here, where you can't do learning." Moreover, in our factory, there is an advantage, which is that their R&D center can't catch up. ”

The little round eyes are waiting.

"We have money to dismantle batteries, piecework wages. Less money for dry batteries, more power batteries, more dismantling and more taking. ”

Madoka was a little excited in an instant: "Me, I also have an intern?" ”

Although in the protective suit, Xiaoyuan felt that Sister Hu gave her a roll of the eyes, "I still have this authority." ”

Madoka suppressed her excitement and asked, "Then can I ask...... Market? ”

Sister Hu: "According to your progress and proficiency today, three or four thousand will come down in half a month." ”

Three or four thousand!

Thousands!

That's her living expenses for most of the semester!

-

There is money to take, there is money to take, three or four thousand, three or four thousand, the small round waist is not sore, and the back is not painful, and he ran back to the dormitory happily, and when he pushed the door open, he was still humming a song in his mouth.

Zhang Jun looked at her in surprise, "Why are you so happy?" You got it? ”

Madoka was stunned, "What do you know?" ”

Zhang Jun: "Of course, I know that I will apply for you to be transferred to the R&D center tonight." ”

Shu Wan came in from outside with a laundry tub, and hurriedly explained, "Junjun, don't talk nonsense, I just asked Senior Brother Yu if you can help Xiaoyuan understand the situation." ”

Qiao Zhiyi followed behind Shu Wan, "You didn't see it, Wanwan was nervous at the time." ”

Zhang Jun waved his hand, "Don't be modest in the evening, who are you looking for, Yu Jinyi, who doesn't know that he is Yu Feng's prince, and there are things he can't do?" ”

Xiaoyuan was stunned, and suddenly realized: "Could it be that our supervisor asked me if I wanted to go to the R&D center when he got off work because he asked Senior Brother Yu for the night?" ”

She touched her head and felt that it was wrong, "but she said that she had some connections and could help me go to the R&D center." ”

"Of course it's because it's late! You're a pig, Chang Eryuan! Zhang Jun shouted, "Why should people help you if they are not relatives." And why didn't you say it yesterday, as soon as you say it tonight, people can help you, this is to ask you to admit your feelings. ”

Qiao Zhiyi was a little happy, "Then Xiaoyuan, you can go to work with us." ”

Shu Wan was also a little excited, "Senior Brother Yu actually went to do this right away?" ”

Zhang Jun nodded violently, "Yes, yes, ah, ah, you are wrong, why don't you tell us about changing dormitories by the way, who can stand changing public toilets and public showers, sometimes you have to queue up for taking a bath at night." ”

Shu Wan hesitated a little, "It's hard to say this......"

Zhang Jun grabbed her hand and shook it, "Say it, I really can't stand it, didn't you notice that you have a big face?" Senior Brother Yu is immediately! Right away! to do Chang Eryuan's matter. ”

Shu Wan's face was slightly red, and she nodded without thinking.

In the midst of jubilation, Madoka said a little embarrassed, "Well, Wanwan, I didn't know that you helped me say hello, so I refused." ”

Everyone looked at her.

Zhang Jun blurted out, "Are you sick, Chang Eryuan, is it easy for Shu Wan to open this mouth?" ”

"I really don't know that I'll help me find Senior Brother Yu tonight." Madoka was also a little moved, and said apologetically, "I'm sorry for wasting your feelings." In this way, Wanwan's classmates are so righteous! I have to invite everyone to dinner! ”

"It's okay." Shu Wan didn't seem to care, "The consumption in the canteen here is not low, you still have to save some flowers." ”

"It's okay, it's okay, just order, I just learned today that the interns of our battery recycling center also have salaries, so you can eat with confidence!"

-

Since he boasted that he was going to invite his classmates to dinner, of course he had to work harder.

On the third day of the internship, Xiao Yuan was arranged to work with Master Wang's apprentice Xiao Qi to dismantle the battery, and of course, Master Wang would also stare at it from time to time.

The principle of battery is a compulsory course in the first year of the active major, and all the courses related at that time, the final exam of Xiaoyuan was full score.

Now, all her theoretical knowledge has been combined with the practice in front of her, and the experience that Master Wang taught her yesterday has been completely digested.

One battery after another is disassembled, the battery is swollen, and it is solved; Battery discharge, solved; plastic case, put it here; Metal case, put it over there.

The battery cell was dismantled and put on the conveyor belt, and the roar of the machine came from afar, filling the space all the time, and it was the sound of the battery cell being shattered.

When it was about to get off work, another batch of goods came to the factory, and the whole factory immediately fell into busyness.

This means that they are working overtime again.

-

In the evening, they dismantled a large lithium iron phosphate power battery.

Its plastic shell is slightly worn, but it is still intact, and after dismantling, the metal part inside is even eighty percent new.

Madoka tapped on its surface, a little surprised: "It's so new, it shouldn't have aged much, right?" ”

Master Wang was handling another battery and came over to take a look: "It should be fine." I guess...... About 60%. ”

Xiao Qi asked, "What do you mean?" ”

Xiaoyuan said: "Master Wang is saying that the battery capacity in it, which used to be able to store 100%, is now only 60%. ”

She turned her head again and asked Master Wang, "You can still save 60%, how to deal with it?" ”

"How? Demolish! ”

"Huh? Isn't that a waste? ”

"Or else?"

Master Wang saw that she didn't understand, and explained two sentences.

-

This is a common thing in power batteries.

The amount of power that lithium batteries can store is definitely decreasing, but a major problem with power batteries is the range. After all, no one wants their car to break down in the middle of the drive.

When the battery's storable capacity is reduced to 80%, users will start to get anxious, and below 60%, the battery will most likely be discarded.

The power battery with insufficient battery life is no different from a waste battery.

-

"It's too wasteful to find another use?" Madoka asked.

Master Wang didn't care, and said with a smile: "Then we have to wait for you college students to figure out a way." ”

Madoka's eyes gradually lit up. She seems to have found the direction of her dissertation!

-

Madoka happily changed into her clothes and got off work, planning to go back to the dormitory immediately after a casual meal to start working on the thesis outline. As a result, when I arrived at the door of the cafeteria, I received a strange phone call, and when I picked it up, it was Jiang Yuwei.

"Chang Eryuan."

"Jiang Yuwei?" Madoka stopped and walked to the door.

"It's me."

Then he paused for a few seconds, and Madoka was about to ask a question, but heard him say, "I heard that you refused to come to the R&D center for money?" ”

"Huh?"

"I heard that in order to make more money, you refused Shu Wan's help and refused the invitation to transfer to the R&D center." Jiang Yuwei repeated, and his voice sank.

"Chang Eryuan, on the one hand, I think if you want to stay in the factory, you should make it clear to your classmates, don't go back on your word, waste other people's kindness, and make Shu Wan go to Senior Brother Yu to apologize. On the other hand, I don't think you're making the right choice. ”

Jiang Yuwei's voice was cold and straightforward.

Chang Eryuan calmed down instantly, holding his mobile phone and standing quietly.

Jiang Yuwei didn't care about Xiaoyuan's silence, he just said what he wanted to say.

"Be a man with a long-term vision. You have outstanding talents in your profession, and you should learn more during your internship in school to lay a good foundation for the future. It is not advisable to focus only on short-term small profits in the near future. If you go to a factory for an internship, you will have a greater amount of knowledge than others, and it will be easy to get ahead in a short period of time, and you may have a greater sense of achievement. But it's all false and doesn't get you a real boost. ”

"Finished?"

Jiang Yuwei didn't expect her to be so calm, "It's over." ”

"First, I didn't ask my classmates to help me find a relationship and transfer to the R&D center, I didn't know about this matter in advance, you can ask Shu Wan, but I am very grateful for her kindness and kindness."

"Second, even if I really apply to go to the first battery factory for money, it's nothing. My family situation is not good, and I want to do my best to earn as much money as possible to reduce the burden on my family, which is not ashamed. Moreover, why do you think you can't learn anything in the first battery factory? Why do you think we can be better than those decades old workers in every field? ”

"A factory produces, no, recycles what we learned in the first grade."

"Year 1 is done because they are fundamental. Everything else is an extension of this. We don't learn theoretical science, we don't fall into practical application, and we can never really appreciate all the details. Do you want me to memorize a few famous quotes to you? ”

Madoka read it to him calmly, "It's shallow on paper, and I never know that I have to do it." If you are a threesome, you must have my teacher. ”

“…… You have a point, but I was reckless. Jiang Yuwei was silent for a moment.

"And a third." Madoka asked very politely and calmly on the phone, "What does this matter to you?" ”
