In the electrical laboratory of the Anhe School of Materials, Qin Hai muttered with a smile after listening to the information introduced by Xu Xiaoqi that Ninzuka Chemical suffered huge losses due to blindly launching a graphene device.
"If you don't blame you, who do you blame?" The person who rebutted him with a smile was Zhang Daiwei, an automotive expert who was invited to the School of Materials. He is now the chief engineer of Hongyuan Automobile Group, and the Hongyuan Automobile designed by him has already been
It has become a representative of domestic brand cars.
"Although I didn't cheat Xinzhong, Xinzhong was cheated because of me." Qin Hai made nonsense of an ancient poem, and then said: "Xinzhong Chemical fell down, and it will take a year and a half to get up again.
It is enough for us to make all the profits we should make from the graphene project. With this money, Mr. Zhang, we will have the capital to develop new energy vehicles."
Zhang Daiwei didn't know much about the secret fight between Daqin Group and Ninzuka Chemical. He just heard Qin Hai talk about it at the dinner table, so he made a casual conversation to adjust the atmosphere. Qin Hai brought the topic back.
He turned his attention back to new energy vehicles.
"Mr. Qin, when I come to Hongze this time, the first thing I want to report to you is the testing of permanent magnet motors. The permanent magnet motors produced by our Anhe Motor Factory have proven to have excellent performance after long-term extreme testing in our experimental workshop.
It fully meets the automotive requirements and is not inferior to similar products in Europe and the United States. It also has an absolute advantage in cost. This means that we have mastered this key technology and no longer have to rely on others." Zhang Daiwei said with excitement.
said with an expression.
A few years ago, Qin Hai and Zhang Daiwei met for the first time. When Zhang Daiwei talked about the idea of new energy vehicles, he felt that it was somewhat related to several directions he was working on. The two parties hit it off immediately and established a strategic cooperation to jointly develop new energy vehicles.
intention.
After that, Zhang Daiwei left Beidian Automobile Group, where he originally worked, and went to Hongyuan Automobile Group. While presiding over the design and production of Hongyuan cars, he also carried out technical reserves for new energy vehicles, waiting for Qin Hai to achieve several things.
With breakthroughs in material technology, the research and development of new energy vehicles can begin.
At present, there are two main categories of new energy vehicles that are feasible for development. One is a vehicle that uses hydrogen as fuel. Its power system is the same as that of a traditional vehicle, which is an internal combustion engine. The only difference is that the fuel used is hydrogen. The advantages of hydrogen energy vehicles are
Environmentally friendly. Because hydrogen only produces water after combustion, without any waste gas. The key to developing 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 are divided into solar vehicles, fuel cell vehicles and battery storage vehicles according to the source of electrical energy.
The new energy vehicles discussed by Zhang Daiwei and Qin Hai are limited to electric storage vehicles, which are the most mature type of technology. Zhang Daiwei proposed to Qin Hai that new energy vehicles using electric storage methods. Technical key points include motors.
, power storage device and power control system. To develop new energy vehicles, these technical problems must be solved.
Motor technology was the first to make breakthroughs. After defeating Ohara Corporation and gaining ownership of the Anhe Motor Factory, Qin Hai invested in a comprehensive technical transformation of the motor factory. Chief engineer Hu Zhizhong and permanent magnet material experts from the Anhe Institute of Materials
Sun Yuzhi led the team to jointly tackle the problem and soon developed several motors based on yttrium-based rare earth permanent magnet materials 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 vehicle motor technology with Hu Zhizhong, Sun Yuzhi and others. He does not know how many times it has undergone technical improvements.
.The automotive permanent magnet motors produced by Anhe Electric Machinery Factory have finally reached the international advanced level and can fully meet the needs of new energy vehicle production.
Since Daqin Group does not have experience in automobile production and marketing, Qin Hai decided from the very beginning that the production of new energy vehicles would be jointly completed by Daqin Group and Hongyuan Automobile Group, and both parties would each hold half of the shares in this project. This
project
Once started, Zhang Daiwei is the general manager who does his duty, which 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 that Daqin Group is regarded as a family
means.
"There is also good news in the development of power control systems." Qin Hai said, "The igbt production line we introduced from the UK has been fully installed and debugged a few months ago, and the first batch of high-quality igbt chips have been produced.
.Gong Zhou promised me to arrange a team to develop an automotive power control system based on domestic IGBT chips for us. I believe there will be results soon."
The Zhou Gong Qin Hai was talking about was the military's aircraft carrier expert Zhou Linlei. Qin Hai used a trick to buy a set of IGBT production equipment from the British Nice Company. The main reason was because the aircraft carrier's electromagnetic ejection system needed an IGBT chip as a
Energy control devices. This set of products
The property rights of the production equipment are owned by Daqin Group, but the production process is under the management of the military. This is Qin Hai’s contribution to the military. However, the production capacity of this production equipment is large enough, and it is impossible for the military to completely digest it.
For products, most 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 vehicle. There are a large number of technical experts in the national defense industry, and the electric energy control system sounds quite interesting.
Although it is advanced, it is trivial for the military industry sector. The flight control system and fire control system that people usually develop are several orders of magnitude more difficult than this. If we leave this technology to them, Qin Hai is
You can absolutely rest assured.
When Zhang Daiwei was at Beidian Automobile Group, he had contact with the military because of the design and production of military vehicles and knew the military's technical strength. After hearing Qin Hai's introduction, he nodded with pleasure and said, "This is too great.
Well, I have confidence in what the science and engineering system has come up with."
"I have already told Zhou Gong that the results must be produced before three months, otherwise don't ask me for help with military affairs in the future." Qin Hainiu said warmly.
Zhang Daiwei laughed and said: "Mr. Qin is really confident and dares to threaten the troops. I think there is no need to be so anxious. Work slowly and carefully. Our new energy vehicles are not in such a hurry."
"Who says there's no rush?" Qin Hai said with wide eyes, "I hope to see a prototype before July next year, 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 Materials
The college has been doing research on power storage technology, which Zhang Daiwei knew. This time Qin Hai specifically called him over from Hongyuan and vowed to see a prototype before July next year. Obviously, the power storage technology has
A decisive breakthrough.
"Hearing is false, seeing is believing." Qin Hai pretended to be a ghost and said, "Let's ask Mr. Zhang to see an experiment first."
After that, Qin Hai shouted to the back of the laboratory: "Mr. Ka'an, are you ready?"
Qin Hai spoke in English. Before he finished speaking, Zhang Daiwei saw a foreigner with a tall nose walking out of the back room, followed by two young Chinese assistants. The foreigner bowed slightly to Qin Hai and Zhang Daiwei.
He turned around and said in blunt Chinese: "Mr. Qin, Mr. Zhang, hello."
"Hello, hello, ho_are_tempt..." Zhang Daiwei replied in a mixture of Chinese and English.
"This is Mr. Ka'an, a foreign scientist hired by our School of Materials Materials." Qin Hai introduced to Zhang Daiwei.
While he was talking, Ka'an had already directed two assistants to set up the experimental device. The experimental device was actually quite simple. It was just an ordinary electric fan, a current inverter, and a soap-sized battery box in the middle.
The wires are connected. Zhang Daiwei is a knowledgeable person and knows
The principle of this experiment is that the battery in the battery box emits DC power, which is converted into AC power through the inverter, and then boosted to drive an electric fan. The power of the electric fan is calculated as 100W. A set of currently common nickel-cadmium rechargeable batteries is about
Can support 5 minutes of operation.
"Can we start?" After seeing the assistants setting up the device, Ka'an asked Qin Hai for instructions.
"Let's get started." Qin Hai said.
Ka'an made a gesture to his assistant, who closed the switch. Just as Zhang Daiwei knew in advance, the electric fan began to rotate at high speed, making a whirring sound. Another assistant of Ka'an pressed a timer on the table.
button, the LCD numbers on the timer beat rhythmically, showing the fan running time.
"The power output is not bad." Zhang Daiwei commented that in addition to capacity, a very important indicator for battery performance evaluation is the ultimate output power. The motor in an electric vehicle is very powerful, and the output power of the battery is very high.
The requirement. The battery box in front of me is only the size of a soap bar, but it can make an electric fan run at full capacity, which is satisfactory at least in terms of output power.
The assistant translated Zhang Daiwei's comments to Ka'an, who said proudly: "This is just a small idea. Theoretically, it can output 10 times more power than now. If you want to see the experiment, we can get one
Let’s try the electric stove.”
"Well, there's no need for that yet." Zhang Daiwei shrugged. He wanted to complain to Qin Hai, saying that some people in Ka'an were crazy, but since Ka'an was right in front of him, he couldn't say it directly. With Zhang Dai
Based on Wei's experience, it is already very good that the existing battery technology can achieve the power output we see now. If it can be improved by 10 times... Is Ka'an's brain okay? (To be continued.)
