electric bicycle?
There was a hint of clarity in Li Changhong's eyes. Someone had mentioned this thing and wanted to study it.
But battery life safety has always been a problem. Can this problem be overcome in a short time?
If the battery problem is solved for electric bicycles, can the same principle be used for mobile phone batteries?
The batteries used by mobile phones on the market today are nickel-cadmium batteries. This kind of battery is large and takes up a lot of space. If you want to reduce the size of your mobile phone, you have to optimize the battery.
The topic they are currently researching is nickel-metal hydride batteries. If the research yields results, it will be able to solve the problem of the size of mobile phones.
So far, there has been some progress.
If it is an electric bicycle, what kind of battery is used?
Electric vehicles are different from mobile phones, and nickel metal hydride seems to work too.
It's just that besides the battery problems that need to be solved, he can think of many things at this moment, such as motors, chargers, controllers, etc.
Su Mingruan heard Li Changhong's words and said directly: "The battery can be a lead-acid battery."
Her words made Li Changhong a little more surprised.
"Lead acid?" He had doubts in his eyes.
The battery research he knows about mainly uses lead-acid batteries in electric vehicles.
As for lead acid...
Su Mingruan nodded: "It's my idea. You can try to see if it can be made. Then I will go back and write a proposal and you can try it out."
"Okay." Li Changhong nodded.
He didn't want to waste his energy on using electric cars.
But he was curious about batteries.
Su Mingruan left school.
After returning home, I took out the patent documents of various components of electric vehicles in the space to find out the changes in batteries and how to optimize them.
There are better batteries than lead-acid in the file, lithium batteries.
Lithium batteries can be used not only in electric vehicles but also in mobile phones.
However, lithium is difficult to obtain and the cost is extremely high. It is not suitable for her to make a profit and have a say in a short period of time.
The steps must be steady and steady, and you cannot expect to reach the destination in one step.
After she transcribed the key points.
Received a call from Su Zhanxi.
Su Zhanxi said that grandma also came to Beijing, and the old man was worried that this would be the last time he saw her.
In the hospital right now.
Asked her if it was convenient, he could bring grandma here.
When grandma comes, she must go there. How can we let the old man run back and forth?
Su Mingruan handed the written plan to the servant sister and asked her to deliver it to Li Changhong.
The plan contains a rough theory of how to make lead-acid batteries.
Not every detailed process has been written down.
She thought that even if Li Changhong couldn't make a battery according to the plan, then Li Changhong's strong friend would definitely be able to.
After all, good people surround themselves with good friends.
He believed that Li Changhong could figure it out.
She sat in the car and closed her eyes to rest, but her mind kept racing.
She couldn't help but wonder if there was any evidence to prove that Lu Jingzhou did this.
After finding the evidence, they arrested Lu Jingzhou and Zhong Manqing.
If Zhong Manqing made some small moves and said some unpleasant words, which only caused her to lose some money, she would not want to deal with the person.
But now she actually wants her father's life.
Now it’s a car accident. If it’s not resolved, what’s the next step?
Did you hire some law-abiding people to kidnap people in broad daylight?
The law is a line, the bottom line of people's hearts. If it is not crossed, she can treat it as a small fight for the sake of Zhou Jibei's and Grandpa Zhong's face.
But that step has been taken.
It must be dealt with promptly.
Also, why did Zhong Manqing pretend to be her and go to the inspection gate late at night?
She couldn't figure it out.
My head hurt from thinking too much, so I quickly stopped my thoughts and forced myself to close my eyes and rest.
The car came to the hospital.
She opened her eyes, the pain in her head lessening slightly.
She got out of the car and walked to the hospital, where she saw old Mrs. Xu Aihua holding a cane outside the ward.
It had just been a while since I last saw her. Grandma’s eye sockets were sunken, her hair was no longer neat, and she looked much older.
That's right, for an old man, the most difficult thing in the world to accept is not whether he will die or not.
Instead, the white-haired person sends the black-haired person.
Dad has been in the hospital for so long. Although my cousin often calls home to reassure the family, I still miss him when I don’t see people alive with my own eyes!
Su Mingruan walked to Xu Aihua: "Grandma, are you hungry? There is a canteen in the hospital. I will take you to eat something."
"If you're not hungry, you can eat in the car." Old Mrs. Xu Aihua was a little restrained.
The hospitals in Beijing are different from those in Yishui.
There are more people here, and the people coming and going seem very busy.
"Let's have something to drink." Su Mingruan looked at Su Zhanxi, who went to the cafeteria to get food.
Su Mingruan took the old lady to the hospital bathroom.
There are so many people on the train that it must be difficult to go to the bathroom.
After going to the bathroom, I took the old man to wash his hands and face, and combed his hair before walking outside the ward.
Su Zhanxi had already made soy milk.
Su Mingruan took it and added a drop of spiritual spring water into it while no one was paying attention.
Then he handed the soy milk to the old lady and said, "Grandma, please drink some. Dad will wake up soon. When he sees you, he will definitely ask if you have eaten or not."
Hearing what Su Mingruan said, Xu Aihua cheered up.
Drink the soy milk in the bowl.
Not a drop was left.
Su Mingruan felt relieved.
Soon, the nurse came out and the patient woke up and could visit.
Xu Aihua and Su Mingruan went in together.
Saw the person lying on the hospital bed.
Her nose was sore.
Su Jianguo's eyes flashed with surprise when he saw Xu Aihua, and then he wanted to sit up and speak.
Seeing this, Su Mingruan quickly pressed the person down: "Don't move around just after the operation. Your injury is not light, so don't cause secondary injuries."
Only then did Su Jianguo calm down.
He looked at the old lady sitting on the edge of the bed.
She couldn't help but comfort the old lady who had traveled all the way to Beijing: "My son is fine, don't worry."
The old lady looked at the doctor who was doing rounds: "Doctor, my son won't die!"
The doctor was very gentle and said with a smile: "The operation was successful. If there are no accidents, there will be no problems. However, it will take a hundred days to break the muscles and bones. This injury will require hospitalization for at least a month. However, don't go too far in a short time." It’s best to rent a house near the hospital, stay there for at least three months, and then go back after multiple re-examinations to make sure everything is OK.”
When Xu Aihua heard this, he finally felt more energetic.
My son will not die!
Just don't die.
God knows how scary it was for her to see Jianguo's bloody appearance in the county hospital.
She didn't sleep well for several days at home.
No matter how bad or confused her son is, she doesn't want her son to die!
The stone hanging in her heart fell to the ground, and she looked at the person on the hospital bed: "Jianguo, take good care of your injuries and take advantage of this time to have a good rest. It has been hard for you to run around all these years. You will go home when you are completely recovered. "
Su Jianguo nodded dullly.
Having experienced life and death, what I valued in the past does not seem to be that important.
But I really understand how to live.
The old lady said a few words to Su Jianguo and found that the man lying on the bed was in low spirits, so she said, "Get a good rest."
After Su Jianguo fell asleep, Su Mingruan took the old lady out of the ward.
She just helped the old lady sit on the chair.
Then he saw Lu Jingzhou's sneaky figure outside.
She couldn't help but think of what she had heard from the detective. Dad's car accident was caused by Lu Jingzhou's car.
Because he didn't kill anyone, Zhong Manqing asked him to hit him again.
It is a pity that the tape recorder did not record these words, otherwise Zhong Manqing and Lu Jingzhou could have been convicted based on the recording.
She looked at Su Zhanxi and asked him to look after the old lady while she followed Lu Jingzhou.
