China releases “Technology Roadmap for Energy-saving and New Energy Vehicles” In 2030, the amount of aluminum used in bicycles exceeds 350kg and the amount of magnesium is 45kg.

On November 14th, a large-scale joint research project -- the energy-saving and new energy vehicle technology roadmap -- commissioned by the National Strategy Committee for Manufacturing Strong Power Construction, commissioned by the Ministry of Industry and Information Technology, led by the China Automotive Engineering Society, and 500 experts completed in one year was released in Shanghai. According to the automotive technology roadmap, magnesium alloy materials will be vigorously promoted in China's auto industry. The specific targets for the magnesium content of bicycles are: 15kg in 2020; 25kg in 2025; and 45kg in 2030.

The overall framework of the roadmap adopts the “1+7” roadmap, which mainly includes: overall technology roadmap, energy-saving automotive technology roadmap, pure electric and plug-in hybrid vehicle technology roadmap, hydrogen fuel cell vehicle technology roadmap, intelligent network Alliance Automotive Technology Roadmap, Automotive Manufacturing Technology Roadmap, Automotive Power Battery Technology Roadmap, Automotive Lightweight Technology Roadmap.

This technical roadmap describes the development blueprint of China's automotive industry technology in the next 15 years. One of the overall goals of the future development of the energy-saving and new-energy automotive technology roadmap is that new energy vehicles will gradually become mainstream products, and the automobile industry will initially realize the transformation of electrification.

Overall objective

The overall goal of the road map blueprint is: By 2020, 2025, and 2030, the annual sales of new energy vehicles in China are expected to reach 2.1 million, 5 million, and 15 million vehicles respectively. The average fuel consumption per 100 kilometers of an energy-saving automobile passenger vehicle is 4 liters in 2025 and 3.2 litres in 2030.

By 2030, the total carbon emissions from the automotive industry will precede the national commitment of “2030 peaks” and the scale of the auto industry will peak before peaking in 2028; new energy vehicles will gradually become mainstream products, and the auto industry will initially realize Electric transformation; Intelligent network-linked technology produces a series of original scientific and technological achievements, and achieves effective popularization and application; the technological innovation system is basically mature and has international competitiveness.

Major milestones

By 2020, the average fuel consumption of new passenger cars will be 5.0 litres/hundred kilometers, and the new car fuel consumption of commercial vehicles will approach the international advanced level. The sales of new energy vehicles will account for more than 7% of the total sales of automobiles, and the market share of driving assistance/partially-automated driving vehicles It reaches 50%. By 2025, the average fuel consumption of new passenger cars will be 4.0 litres/hundred kilometers, and the new car fuel consumption of commercial vehicles will reach the international advanced level. The sales of new energy vehicles will account for more than 20% of the total sales of automobiles, and the market share of highly autonomous vehicles will reach about 15 percent. %. By 2030, passenger car consumption will be 3.2 liters per 100 kilometers. The consumption of commercial vehicles will be synchronized to the international advanced level. The sales of new energy vehicles will account for more than 40% of the total sales of automobiles, and the market share of fully automated vehicles will be close to 10%.

Technical roadmap for each segment:

Under the guidance of the above major goals, the roadmap further consolidates key technologies and clears the way. New energy vehicles and intelligent grid-linked vehicles are the major breakthroughs. The focus is on the optimization and upgrading of energy and power systems, and the improvement of the level of intelligence is the main line, with advanced manufacturing. Supported by common technologies such as lightweighting, it fully promotes the low carbon, information, intelligence, and high quality of the automotive industry. On this basis, the roadmap further proposes seven fields: energy-saving automobiles, pure electric vehicles and plug-in hybrid vehicles, hydrogen fuel cell vehicles, intelligent network-linked vehicles, power batteries, vehicle weight reduction, and automobile manufacturing. Formed a technical roadmap for their respective subdivisions.

Lightweight technology goals

The overall thinking is 2016 to 2020 as the first phase, focusing on the development of ultra-high strength steel and advanced high-strength steel technology, including material performance development, lightweight design methods, molding technology, welding technology, and test evaluation methods to achieve high strength The proportion of steel in automotive applications reaches more than 50%. From 2021 to 2025 as the second stage, the third generation of automotive steel and aluminum alloy technology as the main line, to achieve a mixture of steel and aluminum and other materials, a wide range of aluminum body applications, to achieve aluminum alloy cover and aluminum alloy zero With the mass production and industrial application of components, the proportion of the third-generation automotive steel applications has reached 30% of the body weight. From 2026 to 2030 is the third stage, focusing on the development of magnesium alloy and carbon fiber composite materials technology, solving the problem of recycling of magnesium alloys and composite materials, achieving a wide range of application of carbon fiber composite material hybrid car body and carbon fiber components, and breaking through the complex parts molding Technology and dissimilar part connection technology.

Automotive Manufacturing Technology Target

The overall thinking: First, “green manufacturing, intelligent manufacturing, high-quality manufacturing, and rapid manufacturing” is the main line for development, comprehensively improving quality and efficiency, and reducing consumption. Second, focusing on aluminum, magnesium alloys, and carbon fiber composite materials, and gradually grasping lightweight materials. Manufacturing technology; third is the powertrain and new energy automotive electric drive system as a breakthrough, significantly improve the shaft and other processing and manufacturing technology, to achieve the digitization and intelligence of manufacturing equipment.
