The recently released "Energy Saving and New Energy Vehicle Industry Development Plan (2012-2020)" (hereinafter referred to as "Planning") has caused a strong response in the industry. This "Planning" has been revised many times over the course of a year and a half, and it has been postponed repeatedly, which shows that the government is very cautious about it. Of course, it also reflects the arduous process of unifying the opinions of all parties concerned on the issue of energy conservation and the development of the new energy vehicle industry.
The technical route of the "Plan" is to use pure electric drives as the main strategic orientation for the development of new energy vehicles and the transformation of the automotive industry. At present, the focus is to promote the industrialization of pure electric vehicles and plug-in hybrid vehicles, and promote the popularization of non-plug-in hybrid vehicles. 1. Energy-saving internal combustion engine vehicles, to enhance the overall technical level of China's automobile industry.
The announcement of the "Planning" seems to have reconciled the development route.
"Key Promotion" and "Promotion and Popularization"
In the technical route of the "Planning", the "pure electric vehicle and plug-in hybrid electric vehicle industrialization" is to "focus on promoting", and the "non-plug-in hybrid electric vehicle and energy-saving internal combustion engine car" is to "promote popularization" ". At first glance, the two go hand in hand, without distinction. So, what is the difference between "focusing on promotion" and "promotion"?
Comparing the text of the "Planning" and the solicitation draft that were officially released this time may solve the above-mentioned doubts. "Planning" deleted the words "recently focus on hybrid electric vehicles" and "moderate / heavy hybrid passenger vehicles account for more than 50% of annual passenger car sales" in the consultation draft, which avoids directly stating that hybrid vehicles The controversy that may be caused by the focus of electric vehicles has avoided the high target that medium / heavy hybrid passenger vehicles account for more than 50% of the annual production and sales of passenger vehicles.
After a little scrutiny, it is understandable that "focusing on promotion" is because the technology is difficult, so we have to push it; "promotion and popularization" is a relatively ready-made technology that can be popularized as long as it is promoted. Obviously, "Planning" has "significant advancement" of the industrialization of pure electric vehicles and plug-in hybrid vehicles, and "promotion and popularization" of non-plug-in hybrid vehicles and energy-saving internal combustion engine vehicles. The difference-hybrid electric vehicles have become "an unspecified focus."
Should focus on promoting "additional program"
After the lithium-ion battery pure electric vehicle caught fire, our government departments did not directly intervene in investigations like foreign highway administration departments, nor did they identify an agency responsible for managing the matter. The current situation is that the cause of the problem is mainly left to the parties' complaint and cannot be ascertained realistically; because there is no accident reporting system, more incidents are "covered"; improving safety basically stays on the call required by the principle , And did not make earnest efforts to transform "bad things" into "good things."
Therefore, in countless cases of the crux of the problem, officials will simply think that "pure electric vehicles are not yet mature", placing hybrid vehicles first in order to "promote popularization", while pure electric drives are only Main strategic orientation rather than main tactical actions.
The author believes that as long as there is a market, hybrid electric vehicles can also develop. However, everything should be analyzed and compared. Moderate hybrid cars do not save much fuel-the average fuel saving rate of the 2010 China (Hangzhou) Bus Classic is 14.63%; the 2011 China (Kunming) Bus Classic is 15.61%. "Promotion" is far less beneficial to the country The extended range of pure fuel-electric electric vehicles with a fuel-saving rate of more than 50%, but the "extended range" in the "Planning" did not mention anything.
Although the fuel economy of heavy hybrid vehicles (such as Japan's Prius) can reach 30% to 40%, the technology is besieged by a large number of Japanese patents. China's gearbox foundation is particularly weak, so why bother to do this thankless job?
Therefore, the author believes that China should vigorously develop an extended range pure electric drive electric vehicle with high safety and fuel saving rate. This technology has a good foundation in China and should become a priority vehicle type for China. The government should not only focus on Promote, and popularize.
To prevent "flavoring"
"Plan" proposes to "actively play the role of international cooperation", its content is: to support automotive companies, universities and scientific research institutions to carry out international cooperative research in the field of energy-saving and new energy vehicles basic and cutting-edge technology, to conduct global R & D service outsourcing, overseas Establish R & D institutions, conduct joint R & D and submit patent applications abroad. Actively create conditions to carry out various forms of technical exchanges and cooperation, learn from and draw on advanced foreign technologies and experiences.
It can be seen that the "Planning" clearly defines the international cooperation research and technical exchange and cooperation in the fields of energy-saving and new energy vehicle foundation and cutting-edge technology, but does not propose industrialized international cooperation.
Recently, an official has made a high-profile suggestion that "accelerating the industrialization of electric vehicles is inseparable from international cooperation." This sentence can be understood as the elaboration and interpretation of "Planning", but it also seems to include "accelerating the promotion of international cooperation in the industrialization of electric vehicles". Therefore, the author is concerned that the "actively play the role of international cooperation" in the "Planning" is in danger of changing its flavor.
Now, the assembly of various domestic electric vehicles with foreign components has become an open "secret shortcut". The big factories that have tasted some sweetness on the joint venture road, really don't want to go back to the old road of "market for technology" like fuel cars? Are their determination and enthusiasm for independent innovation so high as the party and government demand?
The author believes that government officials should not send vague signals to these enterprises, but to prevent the cramming of "industrialized international cooperation" private goods under the name of "technical international cooperation," and to prevent relying on such as "Pres localization". The move to "support the scene" is to prevent foreign capital from taking away the main part of profits and eating leftovers. Such "industrialized international cooperation" is obviously not something that the Chinese people are happy to comment on.
This is a more important development route issue than the technical route.
