At the Third Green Industry Conference held in Guangzhou, Su Bo, Vice Minister of the Ministry of Industry and Information Technology, stated that he will start with the five aspects of new energy vehicle industrialization, accelerate the development of energy-saving and environmental protection industries, and promote the development of green industry. Among them, the country will continue to promote the demonstration project of new energy vehicles and the specific implementation plan is being formulated.
At the same time, the automotive industry has also repeatedly urged the acceleration of the popularity of hybrid vehicles in the near future. A number of foreign automakers have also deployed industrial hybrid vehicles.
Continue to promote new energy vehicle demonstration project
Su Bo said that in order to develop energy-saving and environmental protection industries, the demonstration and industrialization of new energy vehicles should be accelerated. He introduced that the country has already implemented 25 new energy vehicle industry technology innovation projects, arranged central government subsidy funds of 4 billion yuan, focusing on supporting pure electric passenger cars and plug-in passenger cars, pure electric commercial vehicles and plug-in Commercial vehicle, fuel cell passenger car, power battery and other items.
By the end of 2012, the country has demonstrated and promoted 27,432 kinds of energy-saving and new-energy vehicles, and the central government has subsidized funds of 5.7 billion yuan. In 25 pilot cities, 174 charging and replacing stations and more than 8,000 charging piles have been built. In the next step, the country will continue to promote the demonstration project of new energy vehicles and the specific implementation plan is being formulated.
In the central government's subsidy program for new energy vehicles introduced in September this year, the principle that the central government will directly subsidize car enterprises has been established to promote the breaking of local protectionism. The promotion of new energy vehicles will continue to rely on cities to promote demonstration operations, especially in megacities. The focus will be on selecting mega-prosperous cities or urban agglomerations with high enthusiasm for energy conservation and emission reduction tasks in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta. This is the first time that a central city has been introduced to promote the promotion of surrounding city groups.
The new policy also focuses on increasing the promotion of new energy vehicles in areas such as government agencies, public institutions, and public transportation, and requires that vehicle purchases in government agencies and public institutions in model cities be tilted toward new energy vehicles, and new or updated public transportation, public affairs, and The proportion of new energy vehicles in logistics and sanitation vehicles shall not be less than 30%.
It is expected that major cities and urban agglomerations are currently working out plans for the promotion and application of new energy, so as to strive for a new round of demonstration and promotion cities. According to the policy, the central government will arrange funds to give comprehensive incentives to the demonstration cities. The award funds will be mainly used for the construction of charging facilities, etc. The demonstration city charging facilities will be given financial incentives according to a certain percentage of their investment in construction to encourage and guide social forces. Participate in the construction and operation of charging facilities.
It is difficult to enjoy special subsidies for hybrid vehicles
In the field of energy-saving vehicle promotion, the automotive industry has gradually formed a consensus that it must speed up the promotion and popularization of ordinary hybrid vehicles. This is because if the hybrid technology is not popular, traditional fuel passenger vehicles will not be able to achieve the "2020 average fuel consumption to 100 liters 5 liters" policy requirements. In addition, accelerating the industrialization of hybrid vehicles will also accumulate technology and market base for plug-in hybrid vehicles and pure electric vehicles.
According to the official website of the China Association of Automobile Manufacturers, at the end of September this year, the association had hosted a seminar on hybrid vehicle technology and promotion. A consensus was reached among government officials and auto industry professionals that hybrid vehicles, as one of the most important and advanced energy-saving technologies, can effectively reduce vehicle fuel consumption and accelerate the promotion of popularization. This is of great significance to promoting the upgrading of the automotive industry. Earlier, Minister of Science and Technology Wan Gang also said that it should accelerate the popularity of hybrid vehicles.
Recently, people in the auto industry have also repeatedly appealed that the policy side should separate the hybrid vehicle from the energy-saving vehicle subsidy program, implement special subsidies, and increase the subsidy. However, because multinational car companies such as Toyota and Honda have absolute advantages in hybrid vehicle technology, they will have more subsidies if they implement public subsidy policies. This, to a certain extent, affected the introduction of the subsidy policy for hybrid vehicles.
At the above seminar, officials from the Ministry of Industry and Information Technology emphasized that "hybrid technology is the focus of the development of automotive energy-saving technologies at this stage." According to the NDRC, "The hybrid vehicle has better energy-saving effects, and domestic vehicle manufacturers are promoting the use of hybrid power. Cars should be brave enough to play.†This statement or means that the promotion of ordinary hybrid vehicles will still rely more on car companies and the market itself.
It is understood that Toyota, Honda, etc. are accelerating the localization of hybrid vehicles and core components. Major domestic groups such as FAW, SAIC, Dongfeng, Chang'an, and GAC have also already deployed the hybrid vehicle market. Among them, the Changan Automobile's Yat-Italy hybrid car will soon be on the market.
“Regardless of whether the country has policies or not, hybrid vehicles are to be industrialized and commercialized. It is based on this judgment that Chang’an has so far introduced four hybrid models and second-generation technologies.†General Manager of Chang’an New Energy Vehicle Yong told reporters from the Nanfang Daily that if it is guided by current laws and regulations, it is expected that by 2018, the sales volume of hybrid vehicles will be very large. Therefore, car companies should firmly deploy hybrid vehicles. Even if they are developed now, they will not be able to meet the requirements of market scale.
Expert perspective
Plug-in hybrids will be able to sell well
The Federation Secretary General Rao Da said recently that BYD’s upcoming "Qin" and other plug-in hybrid vehicles will become the best-selling new energy vehicles.
Rao Da thinks that when the plug-in hybrid vehicle accelerates rapidly, the motor and the engine work at the same time, and the power is particularly good. Compared with the hybrid vehicle, the motor is large, the energy recovered during braking is large, and the power for charging the battery during the operation of the engine is large. In the purely electric driving state, the driving mileage is long, so it is more fuel efficient than a hybrid vehicle in traffic jam, and the fuel saving rate is higher when there are charging conditions. In particular, when the commuter is running below 50 kilometers per day, as long as it is fully charged at night, Can not consume gas. Therefore, plug-in hybrid vehicles are superior to hybrid vehicles in energy saving and power performance.
“The plug-in hybrid vehicle is the best transitional model from the transition from fuel-fuel vehicles to electric vehicles, and electric passenger cars can replace PHV for at least 20 years, while electric heavy-duty trucks take longer to replace PHV.†Said.
The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
