At the Guangzhou Auto Show opened on November 21st, new energy vehicles have once again become the focus of attention in the industry. Whether it is a foreign brand, an independent brand, or a joint-venture independent brand, almost all new energy models are introduced at this year's auto show. According to industry figures, around 2015, the Chinese automobile market is expected to usher in the climax of energy-saving new energy technologies represented by hybrid technologies. The development of new energy vehicles puts higher requirements on automotive steel.
New energy vehicles become the highlight of the auto show
At this auto show, a variety of new energy vehicles were unveiled and attracted the attention of many visitors.
In the showroom where BYD, the independent brand, is located, a glittering model is particularly noticeable. This is the "Qin" dual-mode hybrid sedan from BYD. The vehicle's comprehensive fuel consumption of only 2.0 liters per 100 kilometers has attracted a lot of attention. It accelerates from 0 to 100 kilometers per hour in 5.9 seconds and consumes only 1.6 liters per 100 kilometers. . BYD's staff told the reporter: "This is also the main product of our exhibition."
At the SAIC Group booth, staff members briefed reporters on the Roewe 550 plug-in hybrid car. "This is the first mass-produced three-core plug-in hybrid vehicle in China and has passed stringent tests at home and abroad in battery safety and body safety."
The Great Wall Group’s H7 hybrid SUV and the Chang’an Group’s Yat Dynamic Hybrid sedan also attracted the attention of a large number of visitors. Nearly every worker has two or three visitors “surrounded†and is busy answering the visitors’ requests. The various related issues.
In addition to its own brand cars, foreign brands also have new energy vehicles. For example, in the Japanese brand, Toyota Motor brought NS4 plug-in rechargeable hybrid sports concept car, Yundong Shuangqing II concept car, FT-EVIII concept car, as well as hybrid models PRIUS Prius, CAMRY Camry · Zunrui, etc. . In addition to Toyota, Honda, Kia, and Volkswagen also exhibited with new energy vehicles.
The luxury car at the auto show has always been a key goal for visitors. At this auto show, these luxury car brands are also involved in new energy vehicles. In the just-released hybrid model Infiniti Q50Hhybrid booth, Lexus world premiere new hybrid CT200h booth, Mercedes-Benz domestic new generation E400L hybrid sedan booth gathered a large number of visitors.
Foreign brand auto companies have “grabbed†the domestic new energy auto market, bringing certain pressure to independent brands. Cui Dongshu, deputy secretary-general of the National Passenger Vehicle Market Information Association, was more optimistic about this. He believes that at this stage the European car companies are only trying out the market, the Japanese brand focuses on the low-end car, and BYD and other independent brand products have gradually matured, this pattern is conducive to independent brands continue to occupy a dominant position.
Developing new energy vehicles is a trend
In recent years, the environmental protection requirements faced by the automotive industry have become increasingly stringent. Traditional vehicles have been referred to as one of the major sources of pollution in the urban atmosphere, and it is imperative to manage vehicle exhaust. In this situation, the development of new energy vehicles has become the choice of many automotive companies. China has also introduced a number of related policies to promote the development and use of new energy vehicles. For example, in the “Notice on Continuing the Promotion and Application of New Energy Vehicles†promulgated jointly by the Ministry of Industry and Information, Ministry of Finance, Ministry of Science and Technology and National Development and Reform Commission on September 17, the pure electric vehicles, plug-in hybrid vehicles and fuel cells will be Automobiles are included in the scope of central government subsidies. According to this notice, mega-prosperous cities or urban agglomerations will, in the next two years, accumulate a total of no less than 10,000 new energy vehicles.
In addition to the support of the national level, many local governments in China that restrict purchases and restrictions also have relatively loose regulations for new energy vehicles. This has become an important reason why various auto companies recommend new energy vehicles to consumers at this auto show.
Although both countries and enterprises have high hopes for new energy vehicles, the current level of development of new energy vehicles in China is still far from the expected goal.
According to the data, as of the end of 2012, a total of 39,000 new energy vehicles were modeled and promoted across the country. In the first half of 2013, the production and sales volume of new energy vehicles was only 16,381 vehicles. China's “Energy Conservation and New Energy Vehicle Industry Development Plan (2012~2020)†puts forward: “The cumulative production and sales volume of pure electric vehicles and plug-in hybrid electric vehicles will reach 500,000 units by 2015, and by 2020 pure electric vehicles. The production capacity of automobiles and plug-in hybrid vehicles reached 2 million, and the cumulative production and sales volume exceeded 5 million.†Compared to this goal, China's auto industry still has a long way to go.
Industry analysts believe that although the popularity of new energy vehicles is still a long time away, it is not difficult to see from the auto companies' emphasis on the 2013 Guangzhou Auto Show that new energy vehicles will shift from simple display to large-scale production. The technology that is likely to achieve industrialization is hybrid technology.
New energy vehicles make higher demands on steel
In the future, automotive technology will take the direction of safety, energy conservation, environmental protection, and intelligence as its development direction. New energy vehicles, one of the most important directions for the development of the automobile in the future, will also have higher safety performance requirements for automobiles, and will promote the application of automotive steel products. Bigger challenge.
Kang Yonglin, a professor at the School of Materials Science and Technology at Beijing University of Science and Technology, said that new energy vehicles value the weight of the car more. To achieve lightweight, high-strength, ultra-high-strength steel and aluminum composite lightweight materials can be adopted, and the entire vehicle structure can also be optimized in terms of design. In recent years, the application of thermoformed steel in automobiles has gradually increased. For example, hot-formed steel can be used for anti-collision parts of automobiles and side beams of automobiles. The advantages of thermoformed steel are its simple metallurgical composition, low cost, and ultra-high strength. . In the future, automobile steels still have great potential for development in terms of strength, stiffness, impact resistance, and formability, etc., through the comprehensive use of modern metallurgy, materials science and engineering, and computer simulation techniques.
He Wei, an expert from the Institute of Automobile Industry and Technology at Tsinghua University, also stated that the improvement of material properties is especially important for weight reduction. The use of high-strength steel is an effective measure to reduce weight, and appropriate materials are used in suitable locations and prepared by appropriate processes. The optimal structure.
This point has already been reflected in new energy vehicles. It is reported that at the auto show, the high-strength and ultra-high-strength Steel Plate has reached 67% of the 750 plug-in hybrid sedan body of SAIC Motor Co., Ltd. The body strength level of a luxury car.
According to industry insiders, the future automobile steel still has great advantages in terms of safety, light weight, cost, material life cycle, and green manufacturing. It is still the most important material for automobile manufacturing. In the future, automotive steel will be combined with innovative advanced molding and manufacturing technologies, combined with lightweight materials such as aluminum alloys, so that the weight and emissions of automobiles can meet the requirements of higher standards.
In the future, automotive steel will also use modern computing design techniques to optimize the components and the overall structure, and provide overall solutions to achieve development and continuously improve competitiveness.
