· China's new energy bus sales have exceeded 70,000

In the past 2015, the development of China's new energy vehicles is almost "crazy". The production and sales exceeded 330,000 units, and the cumulative promotion of nearly 500,000 units has become the world's largest new energy vehicle market. According to statistics, four of the world's top 10 new energy vehicle manufacturers with an annual output of over 10,000 vehicles are Chinese companies.
In the face of such a hot new energy vehicle market, the emergence of such words as “beyond” and “the most systematic and comprehensive in the world” shows that some people are complacent in the face of achievements.
However, the competent authorities of the government and well-known experts in the industry still maintain a clear understanding of the situation. On January 23, at the "China Electric Vehicles 100 People's Forum" held in Beijing, the Minister of Science and Technology Wan Gang said that the development of key energy technologies in new energy vehicles is not original enough, especially in power batteries, electric drives and fuel cells. etc. Our basic technology and principle research and development need to be strengthened. For the mastery of the core technology of new energy vehicles, Finance Minister Lou Jiwei also said very frankly that China's new energy vehicle industry is not too late to start development. Now there are still major breakthroughs in high-end products and core technologies. One of the important reasons is that enterprises Over-reliance on government subsidy policies, lacking the resilience and innovative spirit of a decade of hard work. Xin Guobin, deputy minister of the Ministry of Industry and Information Technology, also pointed out that the promotion and application of new energy vehicles still rely mainly on government policies, and the mature and fully competitive market structure has not yet been formed. The common vehicle technology development capability is still not strong, and the vehicle quality is advanced with foreign developed countries. There is still a big gap compared to the level.
The scale of the new energy automobile industry has come out, but how to independently master the core technology and achieve the occupation of the world's automobile commanding heights is the core of national and social concern.
A few days ago, Yutong Bus won the second prize of the 2015 National Science Progress Award. Wan Xinming, vice president of China Automotive Engineering Research Institute, commented on the project of Yutong's “Key Technology R&D and Industrialization of Energy-saving and New Energy Bus” project, which broke through the three technical problems that have long restricted the development of energy-saving and new-energy bus, which is conducive to realization. Large-scale promotion and application of pure electric, plug-in and hybrid three-class passenger cars.
The awarding of the highest scientific and technological level of China to Yutong is undoubtedly a positive signal. In the economic transformation of the country, enterprises in the emerging areas without any reference system, insist on independent research and development, bold innovation, master the key technologies, and seize the commanding heights of the future world bus. The state has awarded honors to Yutong. In fact, in a certain sense, it is setting a benchmark for the upgrading of the new energy automobile industry.
At the "China Electric Vehicle Hundred People's Association", Ouyang Minggao, Executive Vice President of the 100-member Association, pointed out: "In the technological innovation of new energy commercial vehicles, a number of internationally leading innovative technologies have emerged. Yutong's pure electric bus integrated vehicle integration technology In the aspects of low energy consumption, light weight, safety, etc., we have a series of internationally advanced technologies, and won the National Science and Technology Progress Award, and the sales volume is also very good."
In fact, it is the emergence of energy-saving and new-energy bus companies represented by Yutong. Chinese bus has reached a new height in the world of new energy buses.
As early as a few years ago, China was already the world's largest new energy bus market. In 2015, China's new energy buses were far ahead of the world, with sales reaching around 70,000 units. In the 10 new energy vehicle manufacturers with a global output of more than 10,000 vehicles, Yutong has sold more than 20,000 vehicles.
Wang Binggang, a special expert on the major technology of electric vehicles in the 863 Program of the Ministry of Science and Technology, pointed out: "In the Yutong award-winning project, the three technologies of energy saving and control, high-voltage isolated power conversion, and high-density electric drive control are not only leading in the country, but also in the international It is also leading. It is understood that most of the international new energy buses are doing moderate hybrid power, and China's new energy buses have added plug-in mode on the basis of deep mixing. On pure electric buses, China The advantages are more obvious. The foreign pure electric buses are only in the stage of sporadic trial operation, and China's new energy buses have not only reached the official operation stage, but also formed a trend to replace the traditional buses. Last year, new energy buses accounted for the whole. More than half of the bus market."
Wang Binggang said: "The new energy vehicles in the passenger car industry, although the production and sales of the first, but the technical level is not good enough to say more than the wind and Tesla. It can be said with certainty that the new energy bus represented by Yutong has fully achieved its technology. The international advanced level."
As the academic leader of key technologies for electric vehicles and hybrid vehicles, Professor Wang Qingnian from the School of Automotive Engineering of Jilin University agrees with Wang Binggang. He believes: "These three technologies are common technologies that must be possessed by new energy buses. "Advanced level" he said, "The formation of these three technologies is the result of Yutong system matching, integrated design, and integrated control. Some companies' relationship with suppliers is simply to match. Yutong is different, Yutong is from supply. Chain start, collaborative development, coordinating the development of products that meet special needs from the efficiency and response characteristics. Therefore, its technology can reach the efficiency that others can't reach. The 12-meter pure electric bus, under urban conditions, only needs 0.63 kWh. New energy buses in the United States and Europe do not reach this level. This is not only a breakthrough in three technologies, but also a breakthrough in lightweight and battery-integrated management technology.
Wang Binggang agreed with this, Wang Binggang said: "Based on system considerations, Yutong's energy management has been extremely successful. During the driving process, the engine working time is only about 1/3, reaching the level of the Toyota Prius. 12-meter bus 0.63 kWh / 100 km, 45% fuel economy, there is no report above this level."
Wang Binggang also emphasized: "The safety of new energy buses is a big problem at present, and its safety is related to the development of new energy buses. The power battery box developed in the Yutong project to achieve IP67 protection level has solved the wading safety and high cold. Regional adaptation challenges, which do have a major impact on passenger car safety."
It is also obvious that the 330,000 vehicles produced and sold by new energy vehicles in 2015 were mainly the result of government subsidies. If there is no subsidy, whether China's independent auto companies can still stabilize their own market, the answer may be answered like this - like Yutong It is not so difficult for passenger cars to adhere to technological innovation and develop independently and reach and exceed the world's advanced level.
