Starting from July 1, the â€œRegulations on the Management of New Energy Vehicle Production Enterprises and Product Accessâ€ (hereinafter referred to as â€œthe Rulesâ€) was formally implemented. The "Regulations" released this time break down the new energy automotive products into three stages according to their technological level: starting period, development period and maturity period, and accordingly limit the scope of their marketization, and also restrict the access of car companies. In the future, mainstream technologies are limited to promote?
In the "New Energy Vehicle Technology Stage Division Table (applicable before December 31, 2010)" attached to the "Regulations," hybrid vehicles using nickel-hydrogen batteries and lead-acid batteries will be included in the mature period. Lithium-ion battery-powered hybrid passenger cars, commercial vehicles and pure electric vehicles are included in the development period. During the development period, products are allowed to be mass-produced, but they can only be sold and used in the approved areas, and real-time monitoring of the operating status of at least 20% of the products; mature products are the same as conventional automotive products and can be sold and used throughout the country. This means that before December 31, 2010, hybrid and electric vehicles equipped with lithium batteries will be limited to sales areas.
Song Jian, deputy dean of the Institute of Automotive Engineering at Tsinghua University, told the media that 99% of the global market share of hybrid batteries is nickel-hydrogen batteries, and the development of nickel-metal hydride batteries in China is also relatively mature. However, nickel is expensive, and nickel-metal hydride batteries are much more expensive to produce than lithium-ion batteries. Compared with nickel-metal hydride batteries, the new generation of lithium batteries will be halved in weight, and the storage capacity will be increased by more than one time. The mileage will be greatly increased after one charge. And the life of nickel-metal hydride batteries will reach the limit in the next 3 to 5 years. In the long run, lithium batteries will become a more important power source for the development of new energy vehicles in the future.
The voice from the international mainstream automotive industry also generally believes that lithium batteries will gradually replace nickel-metal hydride batteries, becoming the mainstream of the future hybrid and electric vehicles technology line. The mainstream status of nickel-metal hydride batteries will continue until 2011, after which lithium batteries will gradually replace nickel-metal hydride batteries.
Why the battery that will become mainstream in the future will be restricted in the â€œRegulationsâ€? Some commentators believe that new energy vehicles launched by large state-owned auto companies, such as Changâ€™an Jiexun and Chery A5, are equipped with nickel-metal hydride batteries. The F3DM dual-mode electric vehicle that was recently listed is using lithium-ion batteries. Its manufacturer is BYD, a privately owned company. State-owned enterprises' new energy vehicles are more likely to be approved as mature products, while lithium-ion car batteries developed by private enterprises are only listed as development products. This cannot be ruled out artificially dividing access products into several grades, thereby giving different subsidy and suspicion of sales treatment. Its purpose is to ensure that state-owned enterprises have a superior position in the competition for new energy auto market.
In this regard, Song Jian said that nickel-metal hydride batteries at the current stage of research and development than lithium-ion battery mature, will be incorporated into mature products, it is understandable. However, restricting the sales area for products that are in the starting and developing stages is not conducive to the promotion of new energy automobile technologies with more development prospects. Since lithium-ion batteries will replace nickel-metal hydride batteries in the foreseeable future and become the mainstream of development, if private enterprises focus on lithium battery technology research and development, they will be able to gain more and more market share. Methanol fuel car "no name on the list"
Regarding the development of new energy vehicles, the industry has always had a voice that there is a lot to do to improve energy efficiency in existing products and to develop alternative energy vehicles. Former Minister of Machinery Industry and Honorary President of the China Association of Automobile Manufacturers He Guangyuan recently wrote in the media: â€œDo not simply equate new energy vehicles with hybrid, pure electric and fuel cell vehicles, and marginalize other alternative energy vehicles. It is understood that by the end of 2008, China's methanol production capacity has reached 20.83 million tons, with a production of 10.61 million tons, and the amount of resources is comparable to other alternative energy sources. He Guangyuan proposed that alternative energy vehicles based on methanol fuel should be taken as one of the priorities for the development of the new energy automotive industry. However, in the â€œRegulationsâ€ issued by the Ministry of Industry and Information Technology, only DME vehicles are listed as the promotion products in the initial stage for alternative energy vehicles, and methanol vehicles are â€œunknownâ€.
In this regard, Song Jian said that although methanol cars are significantly superior to traditional cars in terms of energy conservation and environmental protection, they can be used as alternative energy sources for small-scale promotion. However, in the aspect of energy-saving and environmental protection standards for hybrid, pure electric and fuel cell vehicles, the direct goal is to achieve the lowest energy consumption and zero emissions. This will not be achieved in the foreseeable future, and this is more in line with the national The purpose of developing new energy vehicles. In addition, methanol is a moderately toxic substance. The use of small-scale gasoline and diesel blends will not cause much harm to the environment and human health. However, it must be applied to a large scale, and its toxicity will increase. It is also unpredictable. Therefore, methanol automobiles have little significance for the development of the new energy automobile industry. It is not normal for the "plan" to include them. The "rules" are more limited than previous ideas.
It is understood that in October 2007, the National Development and Reform Commission also promulgated a â€œRegulations on the Management of Production Access for New Energy Vehicles.â€ By comparing these two â€œrulesâ€, the author found that the core contents of the two are basically the same, then, this release What's new in the rules?
In this regard, CIC Advisor Li Shengmao of the new energy automotive industry researcher said that the biggest difference between the "Rule" issued before and after the release is the standard setter and implementer, which was changed from the National Development and Reform Commission to the Ministry of Industry and Information Technology. In June 2008, after the establishment of the Ministry of Industry and Information Technology, part of the management functions of the automotive industry was transferred from the National Development and Reform Commission to the Ministry of Industry and Information Technology, which included the formulation of product access standards.
In 2007, the National Development and Reform Commission issued the "Regulations for the Access Control of New Energy Vehicles Production," which regulated the access management of new energy vehicles, while the Ministry of Industry and Information Technology focused more on products. The standards set by the Ministry of Industry and Information Technology will carry out the new energy vehicle technology phase. Concretization. The highlight is that it has opened three new energy automotive products for the first time, including compliance with safety, environmental protection, energy conservation, and anti-theft standards. It has been tested by the testing agencies designated by the Ministry of Industry and Information Technology and has not infringed the intellectual property rights of others.
The head of the Institute of Electrical Engineering of the Chinese Academy of Electric Power came to Xiaokang and pointed out: â€œThe four standards of 'safety, environmental protection, energy saving, and anti-theft' are closer to the needs of consumers, especially the anti-theft standards, and it is timely. From the current point of view, new energy sources The cost of autos is high, and users will have higher requirements for anti-theft performance than traditional cars after purchase. This is easy to understand.â€
