"New energy vehicles are not only environmentally friendly, but also cost-effective!" Talking about new energy vehicles, Master Zhao, a taxi driver in Guangzhou, praised the vehicles he drove. Next, Master Zhao calculated an account for the reporter of China Electronics News: a new energy vehicle with a mileage of more than 300 kilometers is fully charged, which costs about 50 kilowatt-hours of electricity, and is billed according to 1.6 yuan per kilowatt-hour, which costs less than 100 yuan. The traditional economic fuel car with the same mileage, calculated according to the fuel consumption of about 0.8 yuan / km, costs more than 200 yuan, almost twice that of new energy vehicles.
New energy vehicles travel through the streets and alleys, making the blue sky and white clouds a distinct background color by reducing exhaust emissions. As a new energy-saving industry, new energy vehicles bear the important responsibility of promoting the realization of carbon peaking goals and carbon neutrality visions, and are one of the protagonists of China's "energy conservation and carbon reduction, green development".
It has made great contributions to energy conservation and carbon reduction
New energy vehicles play an important role in the process of transportation energy transformation, are an important part of achieving the dual carbon target, and contribute greatly to the reduction of China's average annual carbon emissions.
"At normal energy consumption levels, the carbon dioxide produced by fuel vehicles per 100 kilometers is about 14.17 kilograms, and new energy vehicles are only 9.75 kilograms." Xie Nan, a researcher at the Post-Moore Research Office of the Integrated Circuit Research Institute of the China Electronics Information Industry Development Research Institute, told the China Electronics News reporter that compared with traditional fuel vehicles, the carbon dioxide emissions of new energy vehicles will be reduced by about 32%. The "New Energy Vehicle Industry Development Plan (2021-2035)" issued by the General Office of the State Council in 2020 makes it clear that by 2025, the sales volume of new energy vehicles will account for 20%. Considering that the carbon dioxide emissions of the automotive industry account for 16% of China's total carbon dioxide emissions, the application of new energy vehicles will reduce the carbon dioxide emissions of the entire automotive industry by 6.4% and reduce the overall carbon dioxide emissions of China by 1.1%.
Compared with conventional fuel vehicles, the carbon dioxide emissions of pure electric vehicles, which are mainly electricity, are almost halved. Yuan Chengyin, director and general manager of the National New Energy Vehicle Technology Innovation Center and secretary general of the China Automotive Chip Industry Innovation Strategic Alliance, told the China Electronics News reporter that the ratio of fuel and electricity consumption in traditional fuel vehicles and pure electric vehicles is about 1:2, that is, 6.5 liters of fuel consumption per 100 kilometers of A-class vehicles, corresponding to about 13 degrees of electricity consumption, but their corresponding carbon dioxide emissions are halved. The carbon dioxide emissions of traditional fuel vehicles per 100 kilometers are about 16 kilograms, while pure electric vehicles are less than 8 kilograms.
The use of new energy technologies to promote and apply new energy vehicles is a necessary way to achieve energy conservation and emission reduction in the transportation field. As far as the technical route is concerned, new energy vehicles can be divided into pure electric and plug-in hybrid vehicles, which have their own advantages.
Xie Nan told the "China Electronics News" reporter that from the perspective of power source, pure electric vehicles are only powered by on-board power supplies, with significant advantages such as "zero emission", low noise, simple structure, and convenient maintenance. Plug-in hybrid vehicles are a type of transition vehicle that combines the typical characteristics of traditional cars and pure electric vehicles, with one more engine than pure electric vehicles, and the advantage is that it can rely on electric driving and can rely on fuel power when power is insufficient.
In contrast, pure electric vehicles are more likely to become the core force dominating the development trend of the industry. Xie Nan told the "China Electronics News" reporter that this is because the new energy of plug-in hybrid vehicles is not complete, while the on-board power supply technology relied on by pure electric vehicles continues to achieve breakthroughs.
Chinese brands deliver eye-catching answers
New energy vehicles have become the mainstay of China's green economy, and Chinese brands have handed over eye-catching answers in this field.
In 2021, China's new energy vehicles will continue to lead the world, and the sales of new energy vehicles will rank first in the world for 7 consecutive years. According to data from the China Association of Automobile Manufacturers, in 2021, the production and sales of new energy vehicles reached 3.545 million units and 3.521 million units, respectively, an increase of 1.6 times year-on-year, and the market share reached 13.4%, maintaining a booming development situation of production and sales throughout the year. In 2021, China's brand new energy passenger vehicles sold 2.476 million units, an increase of 1.7 times year-on-year, accounting for 74.3% of the total sales of new energy passenger vehicles. It is worth noting that the export performance of new energy vehicles is outstanding, with new energy vehicle exports of 310,000 units, an increase of 3 times year-on-year.
As the leading domestic new energy vehicle enterprise, BYD has long been laid out in the field of energy conservation and carbon reduction in the field of transportation. In order to reduce automobile exhaust, BYD has promoted the full electrification of buses, taxis, online ride-hailing vehicles, urban trucks and special vehicles, and accelerated the replacement of fuel vehicles by new energy vehicles in the field of private cars. In 2020, BYD launched a "blade battery", a high-performance silicon carbide chip, and a high-efficiency DM-i super hybrid system to accelerate the electrification process of private cars.
BAIC BJEV has established and improved a green management system for the whole life cycle of products, improving energy efficiency and making transportation greener and more low-carbon. By the end of 2020, BAIC's new energy vehicle ownership has exceeded 500,000, with a total mileage of 18.3 billion kilometers, and a comprehensive energy saving and emission reduction of 1.94 million tons, equivalent to planting 11.37 million trees.
"BAIC BJEV will continue to promote ecological construction in an all-round way, actively build a sound corporate ecosystem, and make greater efforts for carbon peaking and carbon neutrality." The relevant person in charge of Beiqi Blue Valley told the reporter of China Electronics News.
China's new energy vehicle brands continue to move forward on the road of helping double carbon, and they are also making continuous efforts in the industrialization of electric vehicles. In fact, behind the industrialization of electric vehicles are the two major paths of electrification and digitalization. Yuan Chengyin said that from the perspective of vehicle research and development, design, simulation, verification, manufacturing and use, automotive digital technology is conducive to the realization of the double carbon goal. Digital technology can effectively save resource investment in the process of vehicle design, research and development and verification, improve R&D efficiency, reduce R&D costs, and shorten R&D cycles. Under the support of digitalization, technologies such as artificial intelligence will be more effectively integrated into the automotive industry, and digitalization is the center of change that promotes the large-scale application of artificial intelligence and intelligent technology.
In key links such as chips, innovation is still needed to catch up
The number of new energy vehicle models is increasing, and the market size is also expanding, which provides a great boost to the realization of the double carbon target. From the technical level, China's new energy vehicles have basically reached the international advanced level in batteries, motor drives, intelligent networking and other technologies. However, what needs to be seen is that as an emerging industry, new energy vehicles still have some problems in core technology, market promotion and commercial operation.
The first problem is the lack of core technology. Xie Nan told the "China Electronics News" reporter that domestic companies still have a certain gap with foreign companies in battery energy management systems and lithium-ion battery energy density control. The relevant person in charge of Beiqi Blue Valley emphasized the chip link, mentioning that China's new energy automobile industry still needs innovation to catch up in key links of the industrial chain such as chips.
The person in charge told the "China Electronics News" reporter that on the one hand, enterprises should attach importance to the construction of R & D systems, continue to increase R & D investment, and consolidate their leading advantages in three electric technologies; on the other hand, they should explore and complement each other with other companies in terms of vehicle architecture, intelligent network connection, intelligent driving, etc., to create a cross-industry chain automotive ecosystem and form a convergence effect.
The second problem is the imperfection of the charging infrastructure. With the continuous growth of the number of new energy vehicles, the problem of insufficient structural supply of charging infrastructure in China has become increasingly prominent, and the overall scale is still lagging behind. The number of public charging piles planned for construction in 2020 is about 500,000, but it still does not match the development scale of new energy vehicles in the same period. In addition, the layout of charging facilities is not reasonable enough, the utilization rate of public charging piles is low, the sustainable commercial development model has not yet been formed, and there is a two-way contradiction between the profitability of operating enterprises and the high price of consumer charging.
Based on this, Xie Nan believes that it is necessary to increase the construction of fast charging piles and increase the application of silicon carbide power devices in electric drive systems and charging piles. It is also necessary to actively introduce intelligent management modules to optimize the charging order, and attach importance to the construction of community charging piles and private charging piles.
The third problem is that the aftermarket circulation service system needs to be improved. The person in charge of Beiqi Blue Valley told the "China Electronics News" reporter that in terms of after-sales service, the quality assurance content of different brands of new energy vehicles is uneven, the policy of replacing the battery with the old is not the same, and the after-sales service supporting system is lagging behind, which has a certain negative impact on the cultivation of the consumer market. At the same time, the lack of evaluation standards for the second-hand car market for new energy vehicles, the imperfect circulation system, and the low retention rate of vehicles will affect the long-term development of the market.
"This requires OEMs to strengthen the importance of service after-sales and establish the concept of 'user-oriented'." It is also necessary to establish industry norms as soon as possible, conduct correct value assessment of used cars, and promote the healthy and sustainable development of the industry. The person in charge told reporters.
