Renewed controversy over the way that electric vehicles are cooled by new energy technologies

There was more than two years of buzz in electric cars and it was still the theme of the 2011 Tianjin International Automobile Forum. However, compared with the momentum of development that you competed for in the past two years, the forum is more of a summary and reflection. "The development of new energy vehicles has become a national strategy and vigorously fostering the R&D industrialization of new energy." Su Bo, Deputy Minister of Industry and Information Technology, affirmed the strategic significance of new energy vehicles on the one hand, and also believed that the current technology of new energy vehicles. It is not yet mature; as a transitional hybrid car, that is, energy-saving cars must also accelerate development. “At present, the ministries and commissions of the country are negotiating to continue to support the development of energy-saving cars, but the indicators for energy conservation should be improved.”

In the end, hybrid power is not in the category of new energy, and it has always been the focus of disputes on the technology path of new energy vehicles. In the draft of the new energy vehicle development plan announced in the middle of last year, hybrid power was classified as an energy-saving vehicle, enjoying only a subsidy of 3,000 yuan, while subsidies for pure electric vehicles and plug-in hybrid vehicles were as high as 50,000 yuan and 60,000 yuan. This caused a heated debate among car manufacturers and industry experts. The majority view is that pure electric vehicle technology is not yet mature. It is not only too costly to invest in it, but it also has the opportunity to miss out on energy saving and environmental protection. Therefore, hybrid power as the most practical and feasible energy-saving method should not be neglected.

Whether or not to focus on the objectives and plans of betting on electric vehicles and new energy vehicles, and whether the electric vehicles are overheated, all kinds of disputes about new energy technology pathways are related to the development plan of energy-saving and new energy vehicles that has yet to be introduced ( 2011 to 2020). Since the draft was announced in June last year, the plan has been delayed for more than a year. Some people think that the delay in the planning is due to differences in the opinions of various ministries and commissions of the country. For example, the Ministry of Science and Technology is a firm supporter of electric vehicles, while the Ministry of Industry and Information Technology emphasizes “grasping both hands” and opposing the overheating of electric vehicles.

In this regard, Su Bo publicly refuted: “The media has recently been biased in planning reports. It is believed that the delay in planning was due to the different opinions of various ministries and commissions of the country. But now I can tell you, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and technology. The Ministry of Finance and the Ministry of Finance have a high degree of agreement on planning.” Zhang Shulin, director advisor of the China Automotive Technology and Research Center, also stated that the delay in planning was due to the fact that after the publication of the draft, car companies and the community made a lot of different opinions, which aroused the State Council. The emphasis is, "There may be an impression on the leaders of the State Department that the technical path is not clear."

The Premier questioned the status quo of new energy development. Premier Wen Jiabao recently published "Several Issues Concerning Science and Technology Work" in the "Qiushi" magazine. Among them, he specifically mentioned the current state of development of new energy vehicles: "Hybrid vehicles now have some progress, but there is still a large gap between the technology and the developed countries. Electric vehicle development has just started, and it is still at the beginning of exploration and tracking. At the foreign technology stage, major equipment and materials are imported."

“To deploy strategic emerging industries, we are almost in synch with the Western developed countries. From this point of view, opportunities are captured. However, from the perspective of progress in implementation, the problems are still relatively prominent. First, disorderly development, some places are keen to shop. Stalls, repeated inputs, and redundant construction; second, lack of core technology, many areas are still at the beginning and tracking imitation of foreign technology stage; third, segmentation, decentralization of science and technology resources, and disconnection of production, learning and research.” Premier Wen pointed out in the article that It is on this point that some outstanding problems in China's system have been exposed, and departments and industries have often been unable to form a unified and divisional cooperation on national goals. Systematic issues are a major obstacle to the development of strategic emerging industries."

It can be said that this is the central leadership’s most critical criticism of the current state of development of new energy vehicles, especially electric vehicles. It is vehemently on the surface and actually does not have the core technology. It is still at a low level of repetition. “What is the direction and ultimate goal of the development? Are the hybrid vehicles and electric vehicles that are currently under development the ultimate product? It is not very clear. The next step in the development of new energy vehicles is to focus on what issues to address, including technical route issues and key core technical issues. , input issues, policy support issues, must be as soon as possible clear.

The Premier's reflection set a "key tone" for the forum. In fact, during the two years of the development of the electric leaps and bounds, the sound of reflection has not stopped, but it has been overwhelmed by the wave of heat waves. “Electric vehicles are essentially cars, but they are just a change of powertrain. Therefore, there is no 'curve overtaking' at all.” Zhao Hang, director of the China Automotive Technology and Research Center, believes that the industrialization of new energy vehicles in China The bottleneck is still the product. If we can't make progress in the quality and technology of traditional automobiles, and we can't make breakthroughs in battery technology, we can't really realize industrialization.

From last year's ambitions to the current multitude, with the development of new energy automotive industry, more and more problems and difficulties are presented to the people. Even if you do not pass the car, how to grasp the direction in the corner and drive carefully is also a subject worthy of study.

New energy vehicles do not mean that electric cars are difficult, so they need to be progressive and require step by step.

“I absolutely do not agree that new energy vehicles are electric vehicles, and new energy vehicles should be diversified.” He Guangyuan, former Minister of Machinery Industry, believes that new energy vehicles should support diversified development paths instead of just supporting electric vehicles. “Electric vehicles are not formed or industrialized, and electric vehicles cannot be swarming. I’m not opposed to electric vehicles. But don’t overspeak electric vehicles, and don’t look at the problems of electric vehicles so easily. The main tasks of energy saving and emission reduction, and the investment of policies will all be directed to electric vehicles."

There are not many experts who share the same attitude with He Guangyuan. “The mileage of electric vehicles is still not long enough and there is still a long way to go from industrialization. Although the government has given huge subsidies, the actual sales performance is far from forming a climate.” Zhang Guobao, Director of the National Energy Administration, believes that regardless of electric vehicles, In research and development, for quite some time to come, or before 2020, the car will mainly rely on fossil energy. "As a result, while we are investigating the issue of automotive energy and vigorously researching and developing electric vehicles, we must not neglect the fuel-saving technologies and oil standards of existing vehicles. This is more important and more realistic."

Energy saving or new energy is not a two-sided coin, but it is considered by many companies as a "single choice." Zhang Jinhua, deputy secretary-general of the China Society of Automotive Engineers, told reporters that in the forthcoming plans, the national ministries and the industry have basically reached a consensus to formulate a dual strategy for energy-saving and new energy vehicles. "Of course, the specific approach to government policy support may be different, such as the upgrading of traditional technologies, may consider more to use regulations, such as the third phase of the fuel consumption regulations will be implemented, on the other hand use fiscal incentives to Promote the application and popularization of energy-saving technologies."

In other words, energy-efficient cars have been upgraded to a new level of development. Previously, both the draft plan and the 12th Five-Year Plan for the electric vehicle industry by the Ministry of Science and Technology have emphasized the development goals of new energy vehicles. The draft plan mentioned that by 2020, the cumulative production and sales volume of new energy vehicles will reach 5 million, and medium-to-heavy hybrid passenger cars will account for more than 50% of the annual sales of passenger cars. The scale of energy-saving and new energy automobile industry will be among the highest in the world. aims. In the electric vehicle planning of the Ministry of Science and Technology, the amount of 1 million vehicles will be maintained in 2015, and by the year 2020 it will achieve an annual output of 10 million electric vehicles. In order to achieve this grand goal, the Ministry of Science and Technology will provide 100 billion yuan to subsidize the development of electric vehicles.

"This number is too radical." Zhang Xiaojiu, vice president of China Federation of Machinery Industry, said that new energy planning will not set quantitative targets, and more attention will be paid to quality indicators. The core of quality indicators is to grasp the core The ability to compete. “The staged sales target may have been cancelled; moreover, the state’s proposal to provide 100 billion support funds will also be blurred. According to the WTO principle, the state investment can only be in terms of basic materials, and the state can’t invest in the production capacity. With regard to what to do if it becomes tainted, it would be a state subsidy and it would violate the WTO plan."

However, contrary to the attitude of the Chinese government authorities and experts, multinational car companies still spared no effort in the battle for the commanding heights of electric vehicles. When interviewed by reporters, Nissan Motor Corporation’s Senior Vice President Shinohara made it clear: “From the perspective of the development of new energy vehicles, Nissan’s view is that it will eventually realize the electrification of the power unit. This goal will not change. However, the development of electric vehicles is related to the market and policies, so the development pace of each area may be different and change, but our overall direction will not change. Nissan Motor also strives to be able to quickly The popularization and development of electric vehicles will not change this point."

After a delay of more than a year in the new energy plan, the electric car fever also began to fade. To a certain extent, it is a rational return of the government authorities and the auto industry. This return has left room and time for the further development of the new energy automotive industry.
