A few days ago, 2011 new energy vehicles were put into the Universiade to help achieve the goal of "Green Games." With the advancement of science and technology and economic development, new energy vehicles are gradually entering people's lives. However, what is the new energy vehicle and how far is it from ordinary people?
It is understood that after repeated demonstrations by various departments such as the Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the National Development and Reform Commission, the scope of new energy vehicles has been clarified. Plug-in hybrid vehicles, pure electric vehicles, and fuel cell vehicles are classified as new energy vehicles and will be unplugged. The type of ordinary hybrid car is classified as an energy-saving car.
Zhang Xiaoyu, vice chairman of the China Federation of Machinery Industry and director of the China Association of Automotive Engineers, told the author that the competition in the quality and technology level of automotive products will become more intense in the future, and it is imperative for China’s auto industry to improve its independent innovation capabilities and achieve transformation and upgrading.
It is understood that in the international arena, the new round of international industrial competition with the focus on energy-saving and new energy vehicles has been fully launched. On the one hand, major auto-producing countries adopt concepts such as “low-carbon cars†and “green cars†through stricter fuel consumption and CO2 emission standards and regulations, actively develop and apply advanced automotive energy-saving technologies, consolidate their leading edge in technology, and further strengthen technical barriers. On the other hand, it will promote the development of new energy vehicles as a national strategy, vigorously support the research and development of new energy vehicles, and promote industrialization.
“The transformation of the automotive power system electrification has become an inevitable trend in the development of automotive technology.†The relevant person in charge of the Ministry of Industry and Information Technology stated that new energy vehicles are still in the initial development stage of R&D and industrialization globally. Our country must seize the opportunity and gradually cultivate and form a strategic emerging industry.
However, there are also industry insiders questioning the fuel cell of new energy vehicles. The current automotive battery is mainly based on lithium iron phosphate, lithium manganese oxide as the cathode material, its performance, life expectancy and other indicators are not enough to make pure electric vehicles completely replace the fuel car. "Currently, China's power batteries have a certain gap with the international advanced level in terms of life, reliability, charge and discharge capabilities, energy management and thermal management. After all, research and production related to domestic batteries has only just begun." Ministry of Industry and Information Technology Relevant person in charge said that this also requires the country's long-term stable capital and talent input, and conduct forward-looking and basic research and development.
China's urban residential buildings are mainly based on multi-storey apartment houses. New energy vehicles must enter into millions of households. The problems with charging facilities cannot be evaded. Plus, China's current distribution network is basically fully loaded, and whether multiple electric vehicles are charging at the same time feasible?
“Charging facility construction is not a day's work, but also face many technical problems.†Industry sources pointed out that when it comes to the advantages of electric vehicles, some people may say that electric vehicles and smart grid integration, vehicle power battery can be used as mobile energy storage unit , Through the charging facilities to achieve the "load peaking and valley filling" of electricity load, and improve the power system's ability to accept renewable energy such as wind power and solar energy. However, these analyses are still only theoretical and have not been tested in practice.
“Currently, the smart grid needs a lot of investment in upgrading and upgrading, so it is necessary to fully estimate the difficulty of building charging facilities.†The person in charge of the Ministry of Industry and Information Technology said that in the initial stage of development, charging facilities should be built with the focus on pilot cities, and charging facilities should be integrated into the city’s comprehensive transportation system. In the system planning and urban construction-related industry planning, scientifically determine the construction scale and site distribution, and adapt to advance the construction of charging facilities.
The author has learned that at present, the Ministry of Industry and Information Technology and the Energy Administration are stepping up the development of 15 national and industry standards for charging, involving charging interfaces, communication protocols, energy metering, technical conditions of charging equipment, and safety of charging stations. Aspects. In Beijing, Shanghai, and other areas of urban public transport, government shuttles, and environmental sanitation, the energy-saving vehicles that are independently developed by China and represented by “double electric†pure electric vehicles have been put into daily use.
