Material Empire

Blame me?

In the electrical laboratory of Anhe College of Materials, Qin Hai grumbled after hearing the information introduced by Xu Xiaoqi that Xinzuka Chemical had suffered huge losses due to the blind launch of graphene devices.

Don't blame you, who do you blame? The one who also refuted him with a smile was Zhang Daiwei, an automobile expert who was invited to the School of Materials as a guest. He is now the chief engineer of Hongyuan Automobile Group, and the Hongyuan Automobile designed by him has already It seems to have become a representative of domestic brand cars.

Although I didn't cheat Xinzhong, Xinzhong was cheated because of me. Qin Hai babbled a sentence of ancient Chinese, and then said: Xinzhong Chemical has fallen, and it will take a year and a half to get back up. It is enough for us to earn all the profits we should have made on the graphene project. With this money, Mr. Zhang, we have the capital to develop new energy vehicles.

Zhang Daiwei didn't know much about the secret struggle between Daqin Group and Xinzuka Chemicals, but he just heard Qin Hai talk about it at the dinner table, so he casually said something to adjust the atmosphere. Hearing that Qin Hai brought the topic back to new energy vehicles, he also turned his attention back.

Mr. Qin, when I come to Hongze this time, the first thing I want to report to you is the test of the permanent magnet motor. The permanent magnet motor produced by our Anhe Electric Factory has passed the long-term limit test in our experimental workshop and proved to have excellent performance. It fully meets the requirements of vehicles, and is not inferior to similar products in Europe and the United States, and has an absolute advantage in cost. This means that we have mastered this key technology and do not need to rely on others. Zhang Daiwei was excited. said with an expression.

A few years ago, Qin Hai and Zhang Daiwei met for the first time. Hearing Zhang Daiwei talk about the idea of ​​new energy vehicles, he felt that it was quite related to the several directions he was working on. The two sides hit it off immediately and determined the strategic cooperation intention to jointly develop new energy vehicles.

After that, Zhang Daiwei left Beidian Automobile Group, where he worked, and joined Hongyuan Automobile Group. While he is in charge of the design and production of Hongyuan sedan, he is also making technical reserves for new energy vehicles. He only needs to wait for Qin Hai to achieve a few breakthroughs in material technology before starting the research and development of new energy vehicles.

At present, there are two main categories of new energy vehicles that are feasible to develop. One type is a vehicle that uses hydrogen as fuel, and its power system is the same as that of a traditional vehicle, which is an internal combustion engine, except that the fuel used is hydrogen. The advantage of hydrogen energy vehicles is that it is environmentally friendly, because hydrogen will only produce water after combustion, without any waste gas. The key to the development of hydrogen energy vehicles lies in the storage of hydrogen, which involves the development of hydrogen storage materials.

Another type of new energy vehicles is electric vehicles, which can be divided into solar vehicles, fuel cell vehicles and storage vehicles according to the source of electric energy.

The new energy vehicles discussed by Zhang Daiwei and Qin Hai are limited to electric storage vehicles, which is the most mature type of technology. Zhang Daiwei proposed to Qin Hai that the technical points of new energy vehicles using power storage methods include motors, power storage devices and power control systems. To develop new energy vehicles, these technical problems must be solved.

Motor technology was the first to break through. After defeating Xiaoyuan Club and obtaining the ownership of Anhe Electric Machinery Factory, Qin Hai invested in a comprehensive technical transformation of the electric machinery factory. The chief engineer Hu Zhizhong and Sun Yuzhi, an expert in permanent magnet materials from Anhe Materials College, led the team to jointly tackle key problems, and soon Several motors based on yttrium-based rare earth permanent magnet materials have been developed and entered the international market.

Among these motors, there are several models specially prepared for new energy vehicles. Zhang Daiwei went to Anhe Motor Factory many times to discuss the technology of vehicle motors with Hu Zhizhong, Sun Yuzhi and others. I don't know how many times of technical improvement, the permanent magnet motor for vehicles produced by Anhe Electric Factory has finally reached the international advanced level, which can fully meet the needs of new energy vehicle production.

Since Daqin Group has no experience in automobile production and marketing, from the very beginning, Qin Hai decided that the production of new energy vehicles will be jointly completed by Daqin Group and Hongyuan Automobile Group, and the two parties will each hold half of the shares in this project. Once this project is launched, Zhang Daiwei will be the general manager who will do his part, and this has been recognized by the decision-makers of both parties. When Zhang Daiwei talks about new energy vehicles, he always uses the term we, which means treating Daqin Group as a family.

There is also good news for the development of the power control system. Qin Hai said, The IGBT production line we imported from the UK has been fully installed and debugged a few months ago, and the first batch of high-quality IGBT chips has been produced. Mr. Zhou promised me that he would specially arrange a team to develop an automotive power control system based on domestic IGBT chips for us, and I believe there will be results soon.”

The Zhou Gong Qin Hai mentioned was Zhou Linlei, an aircraft carrier expert in the military. Qin Hai used a trick to buy a set of IGBT production equipment from the British Nice company. The main reason was that the electromagnetic ejection system of the aircraft carrier needed IGBT chips as energy control devices. The property rights of this set of production equipment belong to Daqin Group, but the production process is under the management of the military, which can be regarded as Qin Hai's contribution to the military. However, the production capacity of this set of production equipment is large enough that it is impossible for the military to completely digest these products. Most of the chips will eventually be used in the civilian field.

In order to thank Qin Hai for his help, Zhou Linlei specially arranged an electronic technology team to develop an electric energy control system for Qin Hai's new energy vehicles. There are a large number of technical talents concentrated in the field of defense industry. The power control system sounds quite advanced, but for the military industry department, it is trivial. The flight control system and fire control system that people usually make are several orders of magnitude more difficult than this. Qin Hai can rest assured that he will entrust this technology to them.

When Zhang Daiwei was in Beidian Automobile Group, because of the design and production of military vehicles, he also had contact with the military and knew the technical strength of the military. Hearing Qin Hai's introduction, he nodded in relief and said, This is great. I have confidence in the things produced by the science and engineering system.

I've already told Zhou Gong that the results must be presented three months ago, otherwise you won't be able to ask me for help in military affairs in the future. Qin Hainiu said in a confident manner.

Zhang Daiwei laughed, and said: Boss Qin really has the confidence to threaten the troops. I don't think there is any need to be so anxious. Work slowly and carefully. Our new energy vehicles are not so urgent.

Who says there's no rush? Qin Hai stared and said, I hope to see the prototype before next July, and no later than the end of next year. Our new energy vehicles will be launched on the market.

You mean, you have solved the power storage technology? Zhang Daiwei heard some clues from Qin Hai's words. Because after the motor technology and power control system are solved, the only obstacle is the power storage technology. Anhe School of Materials has been doing research on power storage technology, which Zhang Daiwei knows. This time Qin Hai specially called him over from Hongyuan, and vowed that he would see a prototype before July next year, obviously a decisive breakthrough in power storage technology.

Hearing is believing, seeing is believing. Qin Hai pretended to be delusional and said, Let's ask Mr. Zhang to watch an experiment first.

After finishing speaking, Qin Hai called out to the inside of the laboratory: Mr. Ka'an, are you ready?

Qin Hai spoke English, and before he finished speaking, Zhang Daiwei saw a foreigner with a high nose coming out of the back room, followed by two young Chinese assistants. The foreigner bowed slightly to Qin Hai and Zhang Daiwei, and said in blunt Chinese: Mr. Qin, Mr. Zhang, hello.

Hello, how_are_you... Zhang Daiwei replied in a mixture of Chinese and English.

This is Mr. Ka'an, a foreign scientist hired by our School of Materials. Qin Hai introduced to Zhang Daiwei.

While speaking, Ka'an had directed two assistants to set up the experimental device. This experimental device is actually quite simple, it is an ordinary electric fan, a current inverter, and a battery box the size of soap, connected by wires in the middle. Zhang Daiwei is a knowledgeable person. He knows that the principle of this experiment is that the battery in the battery box generates direct current, which is converted into alternating current by an inverter, and then boosted to drive an electric fan. The power of the electric fan is calculated at 100W, and a set of common nickel-cadmium rechargeable batteries can support the operation for about 5 minutes.

Can we start? Ka'an asked Qin Hai for instructions after seeing the assistants setting up the device.

Let's start. Qin Hai said.

Ka'an gestured to the assistant, and the assistant turned on the electric switch. As Zhang Daiwei knew in advance, the electric fan began to spin at high speed, making a whistling sound. Another of Kaan's assistants pressed the button of a timer on the table, and the LCD numbers on the timer jumped rhythmically, showing the running time of the fan.

The power output is not bad. Zhang Daiwei commented that in addition to the capacity, there is another very important indicator for the performance evaluation of the battery, which is the limit output power. The motors in electric vehicles are very powerful and have high requirements for the output power of the battery. The battery box in front of me is only the size of soap, but it can run an electric fan at full capacity, at least in terms of output power.

The assistant translated Zhang Daiwei's evaluation to Ka'an, and Ka'an said proudly: This is just a small idea. In theory, it can output 10 times more power than it is now. If you want to see the experiment, we can take a Let’s try the electric stove.”

Uh, don't need it for now. Zhang Daiwei shrugged. He wanted to complain to Qin Hai, saying that this Ka'an was crazy, but since Ka'an was right in front of him, he couldn't say it directly. Based on Zhang Daiwei's experience, it is already very good that the current battery technology can reach the current power output, and it can be increased by 10 times... Is Kaan's brain okay?
