Academician Sun Fengchun has always been very low-key and rarely interviewed. He is currently the director of the National Engineering Laboratory of Electric Vehicles. He was the vice president of Beijing Institute of Technology. After he was elected as an academician of the Chinese Academy of Engineering last year, we invited several interviews to be rejected. This time, I have the opportunity to ask Academician Sun to tell the story of his new energy car since the reform and opening up, which makes us feel extraordinarily precious.
During the 1980s, when Sun Fengchun was studying abroad, he learned that electric vehicles are one of the future development directions of automobiles. Since then, he has become attached to new energy vehicles. After graduating from Germany in 1989, he was 6000 marks in foreign companies (about 28,800 yuan). Between the disparity between the salary of 92 yuan in domestic universities and colleges, he resolutely chose the latter and returned to teach. He said that the purpose of studying abroad is to do something for Chinese cars.
In the following decades, Sun Fengchun adhered to the field of new energy vehicles, leading the team to overcome difficulties and accomplish fruitful results. In 1995, China's first electric bus, Yuanyuan, was built. In 1997, China's first completely independent knowledge was developed. The electric motor electronic control system of the property rights, automatic transmission transmission system. And has completed several demonstration projects of electric vehicles such as the Olympic Games, World Expo, Asian Games and so on.
He has long been committed to the research and development of new energy vehicle integration and drive theory, key technology development and engineering application work, and proposed and created China's electric vehicle, charging / changing power station system, vehicle networking and other systems engineering technology system.
He has published 8 books, more than 200 academic papers, 2 second prizes for national technology inventions, 1 second prize for National Science and Technology Progress Awards, 1 He Liang Heli Award and a number of provincial and ministerial awards. 65 items, successively served as the head of the national new energy vehicle expert group, the chief expert of Beijing, etc.
The following is an oral record of Academician Sun Fengchun:
I have been engaged in cars for nearly 40 years, mainly new energy vehicles.
I was born in a remote mountainous area in Linyi County, Hunan Province. I went to elementary school in 1966 and graduated from high school. I studied for 8 years. I went back to the countryside to work as a farmer, I repaired tractors and pumps, worked as private teachers, and made bricks. Bricklayers and many other things. Later, the development of electric vehicles really benefited from the hands-on ability of repairing tractors in the early years.

After the National Restoration of the College Entrance Examination in 1977, I was admitted to the Department of Applied Mechanics at Hunan University. I enrolled in 1978. Later, when I was a graduate student, I returned to the old bank to work on a tractor—Beijing University of Technology, majoring in vehicle engineering. At that time, I was called a professional automobile tractor. From science. Transferred to engineering majors, I feel that the mathematics exam is too simple. I spent 30 minutes to answer. The main direction of studying vehicle engineering is vibration and noise. In 1987, I went to Germany to study for a doctoral degree and chose the direction of tire dynamics. Academician Guo Konghui is doing the same in the field.
Study abroad and become an electric car
Our generation of people born in the past five years, studying abroad is hoping to return to China to do something. When I was a doctoral thesis in Germany, I told my professor that I would like to go to the three major German car companies for an internship and learn more about foreign car companies. I have been internship for three months in each of the three companies. In these companies, there are two places that are absolutely not allowed to go. One is the design workshop for designing new products; the other is the new concept workshop to study future technologies and models. local.
Although China had opened the door to reform and opening up at that time, the Santana sedan was put into production in China. But at that time, the gap between the Chinese and foreign auto industry was so great that we could not lift our heads. After reading the postdoc, the German Volkswagen Company left me, either in Germany. Work, they need the talents of Sino-German exchange; either go back to China to build the public Beijing office, let me be the director of the preparatory office. I declined the invitation of Volkswagen, because studying abroad is to do something for the Chinese auto industry.
During my Ph.D., I learned that electric vehicles are one of the future development directions, but I don't know the details. Because I have done a lot of projects with professors, for example, his two assistants have done projects that have not been made for five years, I have been working for more than half a year. I did it, and the professor was very good to me. Before I returned to China, I told the professor that I wanted to copy some information and bring it back. He gave me the copy room key and let me use it. So, I found it in the library. A lot of electric car related materials, copied, installed a small container. Other information is not needed, useful in the head. At that time, I feel that electric vehicles are the future development direction, I want to study.This is my first connection with an electric car.
'We made the 'Yuanwang''
The real contact with electric cars was in 1992.
When I returned to China, I worked at Beijing Institute of Technology. At that time, the country's Eighth Five-Year Plan had already been finalized, which meant that I had no projects to do. Later, I applied for a Tire Dynamics Natural Fund Project. At that time, Academician Guo Konghui was very supportive and belonged to the Youth Fund Project. The fund was 50,000 yuan. At that time, it was still a small amount. Later, the Ministry of Education gave me a 30,000 yuan excellent returning personnel fund to do dynamic research. After one year, the project was successfully completed.
Sun Fengchun and 'Yuanwanghao' pure electric bus
In 1992, the US government and the Chinese government jointly converted the military electric drive technology into civilian bus technology. The Chinese side was led by the National Defense Science and Technology Commission. At that time, many institutions and enterprises were involved in the country, such as the National University of Defense Technology. Beijing Institute of Technology, Northwestern Polytechnical University, Shengli Bus Factory, Changan Automobile, etc. During the project investigation, Beijing Institute of Technology went to a vice president of the School of Mechanical Engineering. At that time, no one knew that I knew the electric car. Later, the project needed a foreign language. Knowing the technical translation of the business, the vice president found me.
The project negotiation lasted for two years. On the way back from the first negotiation, Shen Rongjun, the general of the National Defense Science and Technology Commission, said to me: 'Xiao Sun, the technical leader of the Chinese Cooperation Committee is you.' In 1994, it was so beaten, 36 years old. I became the chief engineer of this military-to-civilian electric bus.
At that time, the United States was responsible for providing power systems, motors and controllers, batteries, etc. The Chinese side was responsible for the development of electric vehicle bodies and chassis. At that time, I thought that electric vehicles must be developed in the future. We should be the earliest developing electric vehicles in China.
In 1995, we built China's first pure electric bus 'Yuanwanghao'. The electric bus was beautifully made and the project was successful.
In 1995, China’s first pure electric bus, Yuanyuan No., was developed.
'No core technology gives me a heavy blow'
This is the biggest thing that strikes me. I really feel that there is no core technology. The American company’s sitting price has caused the project to end, which means nothing to do. It feels very bad at that time.
Before joining the China-US electric vehicle project in 1992, I was the director of the Vibration and Noise Laboratory of the Beijing Institute of Technology. At that time, the vibration and noise laboratory was the best laboratory and economically efficient laboratory in the school, because the country’s cars and motorcycles were all Engage in localization. I am also the director of the automobile and motorcycle shock absorber testing center.
However, I resigned after I officially entered the electric vehicle project in 1994. I think that when the official project is found, the laboratory director is not good.
Sun Fengchun in the laboratory
It was a 'clean-up'. I was with a teacher from the School of Automatic Control with two students, borrowing a storage room next to the toilet from the school to do the office. The vice-president who went to the United States for inspection at that time Retired, we invited him to study the electric car. There was nothing at the time. The wall of the storage room near the toilet was full of water. I bought four sets of tables and chairs, a computer and a printer. We started this way. .
After I led the team to complete the Sino-US electric bus project, I suffered a blow from the US company in 1996. After that, we made up our minds to develop our own motors and controllers. After more than a year, we made it. In 1997, Beijing officially established the project, this is China's first completely independent intellectual property rights motor electronic control system, automatic transmission transmission system, and in principle is more advanced than foreign countries, energy efficiency ratio is higher than foreign countries, and later won the second prize of national science and technology invention .
Demonstration operation at the Olympic Games
After that, China began to bid for the Olympic Games. From 1998 to 2000, I was one of the technical members of the Beijing Olympics transportation field. Foreign comments on Beijing's air pollution are serious. In 1999, there was one in the Olympic bid: If the Olympic bid is successful, it must be The Olympic Central District achieved zero emissions from the public transportation system. After the successful bid for the Olympic Games, the new energy vehicle was one of the 12 key special projects for the Olympics. I naturally became the chief expert of this project.
I clearly remember that President Xi, who was then Vice President of the State, said to me during the inspection: 'The car can't go wrong because it is running 24 hours.'
For the Olympics project, we have done a lot of technical research. To realize the electric car running 24 hours a day in more than two months, the challenge is very big. And the technicians can't get into the nest, they can only be outside the venue. monitor.
In 2003, when I knew that technicians couldn't get in, I did remote monitoring and operated the reliability of electric vehicles on the roads in Beijing. This is the predecessor of the Internet of Vehicles we made today. , Achievements We have done car networking very early.
The R&D team overcame many difficulties. Finally, it developed the electric vehicle with completely independent intellectual property rights in China. It was the first to realize large-scale operation during the Olympics. It was a great success. I was very happy. This also caused a sensation at that time. Minister Wan Gang asked me to lead the team to Shanghai to help prepare for the World Expo project. In this way, the electric car projects such as the World Expo, Asian Games and so on were completed.
Later, the country began to do demonstration operations in ten cities. First, there were sanitation vehicles after the bus. After the Olympics, Beijing took the lead in making electric sanitation vehicles. In 2009, more than 1,000 vehicles were used in batches.
Establish national engineering laboratory for electric vehicles and national supervision platform for new energy vehicles
Since the beginning of the four-person research and development team, the team has grown to dozens of people. We have accumulated rich research experience in electric vehicle research, industrialization and demonstration operation, and also won many awards. In January 2010, Beijing Polytechnic was formally established. National Engineering Laboratory for Electric Vehicles. The Beijing Electric Vehicle Collaborative Innovation Center and the National Monitoring and Management Center for New Energy Vehicles have been established.
This is my experience with new energy vehicles.
In the 40 years of reform and opening up, I was most impressed by the fact that in 2010, the country listed energy-saving and new-energy vehicles in one of the seven strategic emerging industries. In 2015, it was included in the key areas of China's manufacturing transformation and upgrading. The policy layer faced me. The biggest touch, for the individual is their own professional direction is not wrong; for the Chinese automotive industry, limited to the dual pressure of environmental protection and energy conservation, the development of new energy vehicles is the general trend, the world's government is new energy vehicles The biggest investment, the support is also the biggest. Objectively speaking, China has played a leading role in the strategic decision-making and technology routes.Compared with traditional fuel vehicles, intelligent network integration is easier and faster to implement on new energy vehicles, so that it can be industrialized well and intelligently make traffic. I think this is the development of China's automobile industry. A basic route is the intelligentization and networking of new energy vehicles. The future will also be the development trend of the world automobile industry.
