"Blame me?"

In the electrical laboratory of Anhe Institute of Materials, Qin Hai muttered with a smile after listening to the information introduced by Xu Xiaoqi that Shintsuka Chemical had suffered huge losses due to blindly launching graphene devices.

"Who don't blame you?" Also refuted with a smile is Zhang Daiwei, an automotive expert who was invited to the School of Materials, who is now the chief engineer of Hongyuan Automobile Group, and the Hongyuan Automobile designed by him has become a representative of domestic brand cars.

"Although I don't pit the new mound, the new mound is pitted because of me." Qin Hai nonsense, and then said: "Xinzuka Chemical has fallen on its heels, and it will take a year and a half to get up again, which is enough for us to make all the profits we should make on the graphene project." With this money, Mr. Zhang, we will have capital for new energy vehicles. ”

Zhang Daiwei didn't know much about the secret fight between Daqin Group and Xinzuka Chemical, but he heard Qin Hai say a rough idea at the dinner table, so he casually said something to adjust the atmosphere. Hearing Qin Hai bring the topic back to new energy vehicles, he turned his attention back.

"Mr. Qin, when I came to Hongze this time, I would like to report to you first about the test of permanent magnet motors. The permanent magnet motor produced by our Anhe Electric Machinery Factory has been tested by our experimental workshop for a long time, and has proved that the performance is excellent, fully in line with the requirements of the vehicle, and compared with similar products in Europe and the United States, it is not inferior, and there is an absolute advantage in cost. This means that we have mastered this key technology, and we don't have to rely on others. Zhang Daiwei said with an excited look.

A few years ago, Qin Hai and Zhang Daiwei met for the first time, and when they heard Zhang Daiwei talk about the idea of new energy vehicles, they felt that they had something to do with the direction they were doing. The two sides hit it off and determined the strategic cooperation intention to jointly develop new energy vehicles.

After that, Zhang Daiwei left the Beidian Automobile Group, where he originally worked. to Hongyuan Automobile Group. On the one hand, he presided over the design and production of Hongyuan cars, and on the other hand, he carried out the technical reserve of new energy vehicles, and only waited for Qinhai to achieve several 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 is a car that uses hydrogen as a fuel, and its powertrain is an internal combustion engine, just like a conventional car. It's just that the fuel used is hydrogen. The advantage of hydrogen vehicles is that they are environmentally friendly, because only water is produced after hydrogen is burned, and there are no exhaust gases. The key to the development of hydrogen energy vehicle technology lies in the storage of hydrogen, which involves the development of hydrogen storage materials.

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

Motor technology was the first to break through. After defeating the Ohara company and obtaining the ownership of the Anhe Electric Machinery Factory, Qin Hai invested money to carry out a comprehensive technical transformation of the electric motor factory, and the chief engineer Hu Zhizhong and the permanent magnet material expert Sun Yuzhi of the Anhe Institute of Materials led the team to tackle key problems, and soon developed a number of motors based on yttrium-based rare earth permanent magnet materials, and entered the international market.

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

Since Daqin Group does not have 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 both parties will each have half of the shares in this project. Once the project was launched, Zhang Daiwei was the undisputed general manager. This point has also been recognized by the decision-makers of both sides. When Zhang Daiwei talks about new energy vehicles, he always uses the word "we", which means that Daqin Group is regarded as a family.

"There is also good news in the development of the power control system." Qin Hai said, "We imported the IGBT production line from the UK. A few months ago, all the IGBT chips were installed and commissioned, and the first high-quality IGBT chips have been produced. Zhou Gong promised me to arrange a special team to develop an automotive power control system based on domestic IGBT chips for us, and I believe that there will be results soon. ”

The Zhou Gong that Qin Hai said was Zhou Linlei, an aircraft carrier expert in the military. Qin Hai bought back a set of IGBT production equipment from the British Nice company with a trick, the main reason is that the electromagnetic catapult system of the aircraft carrier needs an IGBT chip as an energy control device. 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 production equipment is large enough that it is impossible for the military to completely digest these products, and 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 a team engaged in electronic technology 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, and the power control system sounds quite profound, but for the military industry, it is trivial. What flight control system and fire control system people usually do are several orders of magnitude more difficult than this. Leaving this technology to them, Qin Hai can rest assured.

When Zhang Daiwei was in the Beidian Automobile Group, he also had contact with the military because of the design and production of military vehicles, and knew the military's technical strength. Hearing Qin Hai's introduction, he nodded with satisfaction and said, "This is great, I am confident in the things that have been made by the science and industry system." ”

"I have already told Zhou Gong that the results must be produced before three months, otherwise the military will not ask me for help in the future." Qin Hainiu said dryly.

Zhang Daiwei laughed and said, "Mr. Qin is really confident and dares to blackmail the troops." I think there is no need to be in such a hurry, slow work and meticulous work, and our new energy vehicles are not so urgent. ”

"Who says it's not in a hurry?" Qin Hai glared and said, "I hope to be able to see the prototype car before July next year, and at the latest by the end of next year, our new energy vehicles will be launched to the market." ”

"You mean, you've solved the power storage technology?" Zhang Daiwei heard some clues from Qin Hai's words. Because after the motor technology and electric energy control system are solved, the only obstacle is the power storage technology. Anhe Institute 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 to see the prototype car before July next year, which is obviously a decisive breakthrough in power storage technology.

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

With that, Qin Hai shouted to the inside of the laboratory, "Mr. Ka'an, are you ready?" ”

Qin Hai was speaking English, and before he could finish speaking, Zhang Daiwei saw a high-nosed foreigner come out of the inner room, followed by two young Chinese assistants. The foreigner bowed slightly to Qin Hai and Zhang Daiwei, and said in stiff Chinese: "Mr. Qin, Mr. Zhang, hello." ”

"Hello, hello, How_are_you......," Zhang Daiwei replied in a mixture of Chinese and English.

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

As he spoke, Caan had already instructed his two assistants to set up the experimental setup. This experimental device is actually quite simple, just an ordinary electric fan, a current inverter, and a soap-sized battery box, connected by wires in the middle. Zhang Daiwei is a knowledgeable person, and knows that the principle of this experiment is that the battery in the battery box emits direct current, which is converted into alternating current by the inverter, and then boosted to drive the electric fan. The power of the electric fan is calculated at 100W, and a set of currently common nickel-cadmium rechargeable batteries can support about 5 minutes of operation.

"Can I start?" After seeing the assistants set up the devices, Ka'an asked Qin Hai for instructions.

"Let's get started." Qin Haidao.

Ka'an gestured to his assistant, who closed the electric switch, and as Zhang Daiwei knew in advance, the electric fan began to spin at high speed, making a whirring sound of wind. Another of Kaan's assistants pressed the button of a timer on the table, and the LCD number on the timer danced rhythmically, showing the time the fan was running.

"The power output is not bad." Zhang Daiwei commented that in addition to the capacity, there is also a very important indicator for the performance evaluation of the battery is the ultimate output power. The motor in an electric vehicle has a lot of power and has high requirements for the output power of the battery. The battery box in front of me is only the size of soap, but it is capable of running an electric fan at full capacity, at least in terms of power output.

The assistant translated Zhang Daiwei's evaluation to Ka'an, who said proudly: "This is just a small meaning, theoretically speaking, it can output 10 times more power than now, if you want to see the experiment, we can take an electric stove to try." ”

"Well, I don't have to." Zhang Daiwei shrugged his shoulders, he had the heart to complain to Qin Hai, saying that some people in this Ka'an were crazy, but because Ka'an was in front of him, he couldn't say it directly. Based on Zhang Daiwei's experience, it is already very good that the existing battery technology can achieve the current power output, and it will be increased by 10 times...... Is Kaan's brain okay?
