The development of China's automobile industry is the pride of China's industrial development and the challenge of China's automobile industry. In 2013, China’s car ownership exceeded 137 million, while China’s total oil consumption reached 520 million tons, of which 310 million tons were imported. At the same time, the pollution of Chinese cities is getting worse. Wan Gang believes that the automobile industry should contribute to this aspect. 130 million vehicles are equivalent to one car for every ten people. In Germany, there are now seven cars for every ten people, eight in the United States, and even nine cars, that is, It is said that the demand for cars in people's lives is obvious. What kind of car do we provide, how can we get into a process of coordinated development of industry, environment and energy, and move in this direction, which is what we should discuss now. This is an opportunity for the automotive industry and a challenge for Chinese cars. Seizing the opportunities and winning the challenges, our development direction will remain vigorous. Adjust energy structure to ensure automotive energy supply Wan Gang introduced that the Chinese government attaches great importance to the adjustment of the energy structure. China has introduced a series of policies in various aspects such as wind power and solar energy. While strengthening basic research and enhancing industrial development, it has also established the world's largest demonstration project for wind and gas storage and transportation. In order to make intermittent power generation. In 2015, the cumulative installed capacity of wind power in China was 129GW, the cumulative installed capacity of photovoltaics was 43GW, and the wind power and photovoltaic power generation capacity was 222.5TWh, which ranked first in the world. However, if we follow the promise of China at the Paris summit, that is to say, by 2030, non-fossil energy will account for 20% of the total energy. In order to achieve this goal, we need to turn these "world first" into two. This is our challenge and opportunity. Wan Gang estimates that the current use of 500,000 electric vehicles in China is less than 3% of the total electricity generated by wind and light. In Wanlian's view, the change in energy structure provides a guarantee for the development of Chinese automobiles and the supply of automotive energy. From the perspective of changes in automobile energy consumption regulations in various countries around the world, energy consumption is rapidly decreasing. According to the requirements of the Chinese government, between 2020 and 5L, the new energy should reach 4.5L or less. The amount of China's annual decline is still quite large compared with other countries in the world. At the same time, the implementation of Euro 6 emissions, Beijing is now Beijing 6 emissions, the remaining gap. China's auto industry has to make great efforts in energy consumption and emissions. In the testing process, Europe has changed from static testing to dynamic testing to high dynamic testing. The new test conditions in Japan have increased from 12 accelerations and 12 decelerations to 26 accelerations and 26 decelerations. The Chinese government has also commissioned the China Automotive Technology Center to study and test the corresponding evolution. The test method has changed, especially the acceleration frequency is increased, the oscillation intensity is large, and the working time is accelerated. New energy vehicles use motor drive, idle stop, automatic energy recovery, and have the inherent advantages of energy saving and emission reduction. Regardless of energy, environmental protection, and the development of the automobile industry, they all point to the development path of new energy. "Three vertical and three horizontal" China's development of new energy vehicle technology roadmap When researching new energy vehicles more than a decade ago, it made a plan for pure electric, hybrid, and fuel cells, identifying key technologies and key assemblies for future development, as well as key vehicle power systems. We refer to the power system as the main core technology consisting of battery and management systems, motors and drive systems, multi-energy systems, as well as hybrid engines and fuel cell engines. These key technologies have been ranked in a key technology on three technical routes. That is what we call the "three vertical and three horizontal" arrangement. From now on, hybrid power is moving from heavy mixing to plug-in and incremental programming in the past, and generators will become power generation systems. Fuel cells have also appeared in two directions, one with a fuel cell as the main power and the other with a fuel cell as an extended-range electric and electric hybrid power source. These three routes eventually become a motor-driven, composed of power generation and storage systems. The technical route, its development can concentrate the greatest strength to overcome the most critical technology, as the government also needs to strengthen the application of infrastructure, research incentives, standard testing, legal regulations and so on. Under such a system, the most important thing is basic research. The most important thing for electric vehicles is power storage batteries. In scientific research, from the basics, we have made great efforts to study the exchange membrane exchange mechanism, the application of nanotechnology, the whole battery failure principle and the temperature field distribution, and the battery group technology and control. Technology has also been invested. It is these inputs that support the development of China's power battery. In 2015, compared with 2011, the unit energy density of the battery has doubled. At the same time, manufacturing costs have been reduced by 50%. In the future, we will strengthen research on basic technologies, continue to consolidate scientific issues in the development process, find scientific solutions, and solve common technical problems. Wan Gang proposed that in the next five years, efforts should be made to double the unit energy density of the battery and reduce the manufacturing cost by another 50%. When it reaches more than 300 watts, the cost will drop below one yuan, and new energy vehicles will have stronger market competitiveness. In terms of driving motors, different key technologies are overcome according to different stages. For example, start-stop generators are now basically used as a series of inputs. Hybrid generators, especially buses, have been well promoted. Especially recently, the development of dual motor drives has become closer to people's needs. The biggest characteristic of electric drive is that there is maximum torque at zero speed, which is good for starting acceleration, but there are certain difficulties for secondary acceleration. Therefore, some companies have developed a direct drive system with dual motors, which varies from low speed to high torque and secondary acceleration. Wangang said without hesitation: "We have short boards on the basic components of electric drives, such as power electronics, electromagnetic interference research, protection and safety, etc., which we must continue to strengthen during the 13th Five-Year Plan period. Important work." Do you need an engine in the era of electric vehicles? Wan Gang believes that we not only need but also strengthen research in this area. Small, lightweight, and electronic will be the future of the engine. For a long time, we need special extensions and special engines. We should work harder in this area. By reducing the displacement and size of the engine by, for example, hybrid power and turbocharging, this adds space for the arrangement of the motor and plays a larger role in the long distance. The cooperation between the engine and the motor is a very important form. The generator is equipped with a generator. How does this generator keep up with the response speed of the battery? This requires a smoother power. After expert discussion, cleaning, high efficiency, small size and light weight will be the trend of the engine. In this case, Chinese companies have also developed plug-in hybrids with a minimum requirement of 50 kilometers. Most Chinese automotive industries use 70 kilometers or 75 kilometers. This is because we have been observing more than 4,000 electric vehicles for many years. It is concluded that about 75% of the cars are under 50 kilometers and 90% are under 75 kilometers. If you can charge every day, more than 90% of plug-in can use pure electric, and achieve zero emissions in urban areas. This is the direction we will develop in the future. Chinese brand cars have also emerged some good products, such as the new energy vehicles of BAIC, BYD and JAC, which are now more and more popular among consumers. Mainly in the cost performance has a great advantage, of course, we have to work hard on high-end models. Fuel cells are also entering the market. Compared with pure electric vehicles, fuel cells may have a longer market path and more waiting. Since the development of the first fuel cell in 2003, research has continued on the basis of the development of colleges and universities and the gradual entry into the enterprise. Last year, SAIC completed fuel cell vehicles in China from south to north, from low to high, to the test of the Qinghai-Tibet Plateau, fuel cell vehicles are gradually moving to the market. Plug-in hybrid vehicles now have some emissions. In the future, fuel cells can be used to supplement short plates. We have combined these technologies in a development direction to make innovation investment more concentrated and efficient. When talking about the safety of electric vehicles, Wan Gang believes that safety is the most critical factor in the development of electric vehicles, and it should be a great deal of work in this regard. On the safety of the battery, the safety of the whole group, the safety of the arrangement, and the safety of the electric vehicle must be ensured under unexpected circumstances. In addition, the security of the Internet era should be the latest technology, which is full-time real-time control. All the buses have been fully controlled at all times. That is to say, during the operation of all buses, every battery is monitored. If there is overheating, it will automatically alarm, so that the safety can be guaranteed. Only in this way can we ensure the safety of the driving height of the car in the new era. Another development is the integration of electric vehicles, smart grids and vehicle networks. Electric vehicles are not only used as energy storage terminals, but they can even blend in the energy Internet, vehicle networking and information interconnection. This will provide a better supply for the new business model. For example, when you rent a car, you can know what kind of car you can rent around, and you can find the electric car in real time, including the location of charging. These are also comprehensive researches in the 13th Five-Year Plan, and have gradually entered the integrated transportation system. Support the internationalization of new energy vehicle development From the growth of China's new energy vehicle production, it is seen that the development of new energy vehicles has adopted the operation of public transportation and gradually entered the mode of family operation. In 2011, there were less than 5,000 new energy vehicles, and it was only 85,000 vehicles in 2014. At that time, it was difficult to reach the 500,000 indicators. But last year it reached more than 370,000. But here is a point to tell us that the promotion of new energy vehicles is not only a matter of research and development, but also the support of the whole society. For the new energy vehicles to cancel the lottery, cancel the restrictions, ensure priority parking, can give policy force, comprehensive innovation, can truly make the new energy vehicle industry develop. At the end of 2015, the global electric vehicle production exceeded 1.45 million units. In 2008-2014, the global EVI 16 member countries increased their investment in new energy vehicles. "This year's Paris Climate Summit I have the honor to participate in the joint action plan for the energy mission. We will work with more than 20 countries to double the investment in clean energy in the next five years. So this will also be our electric vehicle, new energy. The car is also a focus of research and development in the energy mission in the future.†Wan Gang said. At the same time, China has carried out international cooperation in the research and development of new energy vehicles, and established the China and Germany electric vehicle research centers, as well as the clean car alliances between China and the United States. The biggest feature is the so-called "2+2" mode. The combination of production and research between the Chinese and foreign parties has promoted the joint efforts of basic research and policy research. “I am very pleased to see that Chinese auto companies and international auto companies are merging. Last year, I spent some time personally driving the cars jointly developed by Daimler-Benz and BYD. Such joint research and development vehicles also received all the preferential policies. We have repeatedly said that China's new energy vehicles are open, and they will treat each other equally in the Chinese market. From this perspective, we are more supportive of the internationalization of new energy vehicle development," Wan Gang said. As the development of the industry, there are still great challenges in the future. The core technology research and development needs to continue to deepen, and the development of batteries, motors, basic research, core technologies and common technologies should continue to be strengthened. Vehicle abilities, integration capabilities, and especially security also require us to take advantage of new technologies and new forms to enhance them. The demand for new energy automobile industry and market is very strong. It is necessary to firmly grasp the development direction of automobile electrification, light weight and intelligent, and continuously innovate the business model of the automobile market. Electric vehicles in China are a promising and prosperous sunrise industry, an industry that carries responsibility and mission, and the focus of technological innovation in the future.
