Traveling through 70's wine

Chapter 180 Battery

Wen Qing walked all the way to the top of the mountain. On the way, she met the orchard keeper, Lao Li, who was weeding. Wen Qing took the initiative to greet him, "Uncle Li, good morning!"

Old Li didn't expect to meet Wen Qing so early, and quickly replied: "Xiao Wen, good morning!"

Wen Qing looked at the lush orchard and felt very happy. She waved to Lao Li and continued to climb to the top of the mountain.

The feed factory could be seen after crossing the hill, so Wen Qing quickened his pace.

The feed factory's factory building has been half built and the foundation has been laid. The four walls and the middle pillars of the factory building are all made of steel bars and cement. The factory roads have also been tidied up, and the general situation of the factory can be seen.

Wen Qing found the construction team leader Shen Wei to learn about the progress of the project. According to him, the factory would not be completed until the end of August.

The subscription funds of the feed factory shareholders have all been deposited into the account, and she went to find Xu Shengli to find out how the funds were used.

Together, they found Lao Tian, ​​the accountant of the feed factory. They had spent 30 yuan on building the factory, 80 yuan on purchasing equipment, and 11 yuan on daily expenses for several months. There was still 86 yuan in the account, and then they had to pay 35 yuan in construction costs. In fact, funds were very tight.

Seeing Wen Qing frowning, Xu Shengli said confidently, "Xiao Wen, I have already told the people in the credit department of ICBC that they are very interested in our feed factory and basically agree to lend us money. We just need you to go there once so that we can talk face to face."

Wen Qing had worked in the Sifeng District Industrial Bureau and knew that enterprises could develop faster with the use of loans. She nodded and asked him to contact the bank and they would meet tomorrow.

The feed factory had buildings and land, sufficient capital, and support from the commune, so the loan negotiations went relatively smoothly. Wen Qing mortgaged 30 acres of land and borrowed 50 yuan as working capital.

In order to support the development of the collective economy, the bank gave them certain preferential treatment. The loan interest rate was only around 5%. Wen Qing thought it was reasonable and went through the loan procedures.

After the funds arrived, Wen Qing went to the school-run factory to check out the production of the mixers and granulators. Director Li said that there would be no problem for them to complete the equipment production on schedule.

Their mixers can not only mix various crushed raw grains, but also add various solid and liquid additives. Their pelletizers can also produce puffed pellets of different specifications.

Wen Qing also commissioned the school-run factory to process some pipes. Wen Qing: "Director Li, our new factory can be completed in August. You must deliver on time."

Director Li patted his chest and said, "Xiao Wen, I guarantee that the delivery will be on time and I will never delay your work."

After leaving the school-run factory, seeing that it was still early, Wen Qing went to the Schindler Bicycle Shop to check the financial statements for the previous quarter. This was something everyone had agreed on before, that as a shareholder, Wen Qing would not participate in the company's daily operations, but would have voting and supervisory rights.

When they arrived at the store, Fang Yuan was the only one there. Seeing Wen Qing coming, he said a little embarrassedly, "Sister Wen is here?"

Wen Qing smiled and said, "Are you the only one looking after the store?" The two chatted about the company's business situation.

The sales of mountain bikes, road bikes, and city bikes designed by Wen Qing are rising steadily. Fang Yuan said, "Sister Wen, your designs are definitely at the forefront of the market."

Wen Qing smiled but said nothing. Now she was just a shareholder of Xunda.

Wen Qing asked Fang Yuan to take out the financial statements of Schindler Store and Bicycle Factory and gave them to her. She glanced at them and said, "Can you give me these financial statements? I want to take them home and read them."

Fang Yuan said, "No problem, take it back and have a look."

Wen Qing did not return to Erxia Village, but returned to Huashuijing Lane. She took out the design drawings of the electric bicycle. This design had been delayed for half a year. She thought that bicycles could still be made for 2 or 3 years, and then it would be the era of electric vehicles.

She first designed the electric bicycle, then found a factory to make a sample, and then launched it directly to seize the market.

She devoted all her energy to the design, striving to complete the battery transformation as quickly as possible, and did not even have time to eat dinner.

Although electric bicycles are bicycles, they have batteries as their power source and an electrical system more than bicycles, including batteries, motors, controllers, and braking systems. The mechanical parts of the bicycles have also been optimized, such as the front and rear shock absorbers, handlebars, flywheels, and wheels.

In order to reduce costs, Wen Qing did not make a dashboard. Instead, he used indicator lights to display the battery power and directly controlled the turning lights with buttons on the handlebars.

It was not until dawn that Wen Qing put down her pen, quickly washed her face, and went to bed.

Although her power increased after the upgrade, sleeping is a habit and is also conducive to mental relaxation.

She and Zhuang Xien are divorced, so she is not going to sell the electric bicycle to Schindler Bicycle Factory anymore and is looking for someone else to cooperate with.

The battery is the core of the electric vehicle. In her previous life, the electric bicycles Wen Qing had seen all used lithium batteries, and she didn't know much about lead-acid batteries. In order to design a good battery, she thought of many ways. Fortunately, she had taken a minor in chemistry and consulted a lot of information. The battery of the electric bicycle she designed used lead-acid batteries.

She used lead powder, sulfuric acid, red lead and other additives as positive electrode lead paste, and lead powder, sulfuric acid, barium sulfate and expander as negative electrode lead paste. Other metals were added to the lead-calcium alloy for the coated plate grid to make the current distribution more uniform. She used dilute sulfuric acid solution as the electrolyte. The battery she designed has higher energy efficiency and smaller size than existing batteries.

In order to extend the battery life, Wen Qing used tubular plates, which extended the battery life. She also designed a battery charging device to ensure that the battery charging time is short and safer.

In order to maintain a longer mileage for the electric bicycle, Wen Qing used 6 batteries in series. Based on a daily mileage of 20 kilometers, this electric bicycle can be charged once every three days, which is in line with the usage habits of most people.

Suddenly, she thought that she could also find a manufacturer to cooperate with for this lead-acid battery.

Today's cars also use lead-acid batteries, so there are many battery manufacturers on the market. She looked up the telephone directory and called them one by one.

After making seven or eight phone calls, Wen Qing explained her design ideas on the phone. A manufacturer on the southeast coast expressed its willingness to cooperate with her and asked Wen Qing to go to their factory for detailed discussions.

Wen Qing asked for the address, which was Xiyang, a city in the northeastern part of Vietnam Province. She immediately bought a train ticket, packed her luggage, said goodbye to Liu Quan and Xu Shengli, and set off.

From Pingjing to Xiayang in Vietnam Province, one needs to change trains in Xiamen, and even if one takes the express train it will take a day and a night.

Wen Qing arrived in Xieyang City the next night. Xieyang City is a famous hometown of overseas Chinese and also a water city. It has three major water towns, namely Rongjiang, Longjiang and Lianjiang, and is known as the "Lotus on the Water".

Mid-May was the rainy season. It was drizzling when Wen Qing walked out of the train station. She took out her umbrella and walked out of the station carrying her bag.

There were many tricycles soliciting passengers outside the train station. Wen Qing found a man who looked honest and told him the address of the Changfeng Battery Factory. The man told her the price. Wen Qing nodded and got on the tricycle.

Xieyang City is not big, and the man rode for more than 20 minutes to get there. Wen Qing got off the bike, gave the money, and walked along the street to a hotel not far from the Changfeng Battery Factory, where they stayed.
