As of October 9, the Shanghai World Expo SAIC – General Motors Pavilion has exceeded 200 million visitors. Audiences queuing for hours, as is to see the “direct 2030″ and “leaves” and “EN-V” two new energy future concept car style. Hall also learned that journalists in the car, SAIC provided by the hp pavilion dv9000 battery, hp pavilion dv8000 battery 1100 World Expo electric vehicle demonstration of new energy vehicles, including electric, hybrid, fuel cells and super-power vehicles, more than five months to run in good condition, all vehicles in good condition rate of more than 99%, indicating that the world’s largest commercial operation of new energy vehicles have been the early success.
New energy concept cars at the Expo demonstrates the strong popularity, shows a broad new energy automotive industry, development prospects and opportunities.
Tensions in the global oil resources and environmental issues in the context of an increasingly grim, the future direction of cars become the focus of social concern. Automobile Museum recently held in the “direct 2030″ Sustainable Transport Forum Series, China Electric Power Research Institute Electric Power Research Institute, Superconducting made to well-off, the development of electric vehicles and electric vehicle technology widely used, will also bring opportunities and challenges; electric vehicles in China in 2015 target for 500,000 to 1,000,000, which China will become the world’s largest electric vehicle charging facilities and one of the markets.
The current development of new energy vehicles energy conservation has become a global automotive research and development of science and technology high ground to alternative energy, hybrid dell xps m1530 battery, dell xps m1730 battery, pure electric as the representative of the new energy technologies, showing a trend of rapid development. It is understood that, GM is increasing spending on research and development in hybrids, electric vehicles and fuel cell vehicles such as the electrification of a series of industry-leading technology products. The company launched in North America this year will be the Chevrolet Volt extended range electric vehicle, is the only one can run in any weather conditions, and not run out of battery electric vehicles, the maximum mileage over 500 km can achieve “zero fuel consumption and zero emissions.” In China, the government continued to put good policy, driven by major car manufacturers are actively developing new energy vehicles. Xiao Guo, vice president of SAIC General has revealed that the car companies to develop new energy technology route has been determined, will target the trend of electric vehicle drive, hybrid and electric vehicles to speed up the industrialization and promoting fuel cell vehicle research and development of upgrades. In accordance with the SAIC’s new energy vehicle development goals by 2012 to market the company’s nearly 20,000 to pure electric vehicles and plug-in hybrid vehicles.
To well-off analysis, large-scale application of electric cars is a revolution in the world automobile industry, will the city power grid and electricity infrastructure have a significant impact, while the chemical battery and the new lightweight materials for cars is also a higher matching requirements.
The core of new energy vehicles is the battery technology, the future use of high-performance car batteries, is dell studio 1745 battery, dell studio 1747 battery a world-class science and technology issues, is the first challenge facing the energy storage density, the current battery energy density is still about 100 times lower than the liquid fuel. This area of research and development, must rely on chemical technology breakthrough. The second challenge is the battery pack thermal management system, you need heat in the winter environment, the battery pack to maintain constant temperature, which requires the development of special materials and innovative design. Such as the Volt battery packs, by the GM and LG Chemical Company jointly developed innovative battery cooling system.
This reporter learned that hundreds of domestic enterprises have been competing to develop lithium batteries. Relative to the lead-acid batteries, nickel metal hydride batteries, lithium ion batteries with high energy density, long cycle life, self-discharge rate is small and no memory effect and the green features, but all companies in the lithium battery development, the stage and far in terms sony vgp-bps13 battery, sony vgp-bps21 battery of core technology to master. Shanghai Shen is general manager of technology consulting firm, told reporters Zhang Ding, lithium battery cathode, anode, electrolyte, separator and packing materials and many related to chemicals, which still need to import key materials of the diaphragm, the domestic strength of research should be organized; now on the market the lithium battery case too, have to be addressed. Ding Zhang suggested that the introduction of national standards committee as soon as the battery electric vehicle standards, interface standards and standard charging stations to promote the electric car industry and China’s low-carbon era of green transport.
Bayer MaterialScience Leihuan Li, general manager of China’s auto business, said: “The new energy vehicles currently there are still many problems, such as heavier battery, the battery temperature and the efficiency of their own problems, needs to develop new materials and customized solutions.” It is noted that Bayer Technical Automotive Center in Shanghai, has been in the automotive industry chain to cooperate with car manufacturers in improving vehicle safety under the premise of high-performance plastics and light composite material widely used in automotive interior and exterior parts , bumper, lights and so on. Recently, the center has successfully developed a polycarbonate car windows and high strength, lightweight alloy sheet of plastic body, and to address the new electric vehicle battery casing material problems.
Chemical materials (including tires) account for the production of new energy vehicles up to 70% the proportion of the sony 14870582 keyboard, sony vaio vgn-ns keyboard material. XIAO Guo Pu believes that the current development of new energy vehicles is one of the main obstacles to high costs, therefore, reduce the cost of battery materials, urgent need to intensify research efforts in the chemical industry.
