"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 range of more than 300 kilometers will consume more than 50 kwh of electricity. It costs less than 100 yuan according to 1.6 yuan per kWh. The traditional fuel economy car with the same mileage costs more than 200 yuan according to the fuel consumption of about 0.8 yuan / km, almost twice that of new energy vehicles.
New energy vehicles travel through the streets and alleys, making the blue sky and white clouds a bright background by reducing exhaust emissions. As a new energy-saving industry, new energy vehicles bear the important responsibility of promoting the realization of the goal of carbon peak and the vision of carbon neutralization. They are one of the protagonists of China's "energy conservation, carbon reduction and green development".
Make great contributions to energy conservation and carbon reduction
New energy vehicles play an important role in the process of transportation energy transformation. They are an important part in achieving the dual carbon goal and have contributed a great deal to the reduction of China's total annual carbon emissions.
"Under the normal energy consumption level, the carbon dioxide produced by fuel vehicles per 100 kilometers is about 14.17 kg, and that of new energy vehicles is only 9.75 kg." Xie Nan, a researcher at houmoore Research Office of integrated circuit Research Institute of China Electronic Information Industry Development Research Institute, told China Electronics News that compared with traditional fuel vehicles, the carbon dioxide emission 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 clearly stipulates that the sales volume of new energy vehicles will account for 20% by 2025. Considering that the carbon dioxide emissions of the automobile 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 whole automobile industry by 6.4% and China's overall carbon dioxide emissions by 1.1%.
Compared with traditional fuel vehicles, carbon dioxide emissions of pure electric vehicles dominated by electricity are almost halved. Yuan Chengyin, director and general manager of the national new energy vehicle technology innovation center and Secretary General of China Automotive chip industry innovation strategic alliance, told China Electronics News that the proportion of fuel and power consumption of traditional fuel vehicles and pure electric vehicles is about 1:2, that is, class a vehicles with a fuel consumption of 6.5 liters per 100 kilometers correspond to a power consumption of about 13 kwh, But their corresponding carbon dioxide emissions are halved. The carbon dioxide emission of 100 kilometers of traditional fuel vehicles is about 16 kg, while that of pure electric vehicles is less than 8 kg.
Using new energy technology to promote and apply new energy vehicles is a necessary way to achieve energy conservation and emission reduction in the transportation field. In terms of technical route, new energy vehicles can be divided into pure electric vehicles and plug-in hybrid vehicles, both of which have their own advantages.
Xie Nan told China Electronics News that from the perspective of power source, pure electric vehicle is a vehicle powered only by on-board power supply, which has significant advantages such as "zero emission", low noise, simple structure and convenient maintenance. Plug in hybrid vehicle is a kind of transition vehicle with the typical characteristics of traditional vehicle and pure electric vehicle. It has one more engine than pure electric vehicle. Its advantage is that it can not only rely on electric drive, but also rely on fuel power when power is insufficient.
In contrast, pure electric vehicles are more likely to become the core force dominating the industrial development trend. Xie Nan told China Electronics News 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 hand over bright answers
New energy vehicles have become the mainstay of China's green economy, and Chinese brands have given brilliant answers in this field.
In 2021, China Shanxi Guoxin Energy Corporation Limited(600617) automobile continued to lead the world, and the sales of new energy vehicles ranked first in the world for seven consecutive years. According to the data of China Automobile Industry Association, in 2021, the production and sales of new energy vehicles were 3.545 million and 3.521 million respectively, an increase of 1.6 times year-on-year, and the market share reached 13.4%. The development situation of both production and sales was maintained throughout the year. In 2021, the sales of Chinese brand new energy passenger vehicles were 2.476 million, a year-on-year increase of 1.7 times, accounting for 74.3% of the total sales of new energy passenger vehicles. It is noteworthy that the export performance of new energy vehicles is outstanding, with the export of 310000 new energy vehicles, a year-on-year increase of 3 times.
As a Shanxi Guoxin Energy Corporation Limited(600617) automobile head enterprise, Byd Company Limited(002594) has long had a layout in energy conservation and carbon reduction in the field of transportation. In order to reduce automobile exhaust, Byd Company Limited(002594) promote the comprehensive electrification of public transport, taxi, online car hailing, urban trucks and special vehicles, and accelerate the substitution of new energy vehicles for fuel vehicles in the field of private cars. In 2020, Byd Company Limited(002594) launched "blade battery", high-performance silicon carbide chip and high-efficiency DM-I super hybrid system to accelerate the electrification process of private cars.
BAIC new energy has established and improved the green management system for the whole product life cycle, improved energy utilization efficiency, and made transportation greener and low-carbon. By the end of 2020, BAIC had more than 500000 new energy vehicles, with a total mileage of 18.3 billion kilometers, comprehensive energy conservation and emission reduction of 1.94 million tons, equivalent to planting 11.37 million trees.
"BAIC new energy will continue to promote ecological construction in an all-round way, actively build a perfect enterprise ecosystem, and make greater efforts for carbon peak and carbon neutralization." The relevant person in charge told the reporter of China Electronics News.
The Shanxi Guoxin Energy Corporation Limited(600617) automobile brand is constantly moving forward on the road of helping double carbon, and is also making continuous efforts in the industrialization of electric vehicles. In fact, behind the industrialization of electric vehicles are the two paths of electrification and digitization. Yuan Chengyin said that from the aspects of vehicle R & D, design, simulation, verification, manufacturing and use, automotive digital technology is conducive to the realization of the dual carbon goal. Digital technology can effectively save resource investment in vehicle design, R & D and verification, improve R & D efficiency, reduce R & D cost and shorten R & D cycle. With the support of digitization, artificial intelligence and other technologies will be more effectively integrated into the automotive industry, and digitization is the reform center to promote the large-scale application of artificial intelligence and intelligent technology.
Innovation is still needed to catch up in key links such as chips
The increasing number of new energy vehicle models and the expanding market scale provide great help for the realization of the dual carbon goal. In terms of technical level, China Shanxi Guoxin Energy Corporation Limited(600617) automobile has basically reached the international advanced level in battery, motor drive, intelligent network connection and other technologies. However, 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 China Electronics News that Chinese enterprises still have a certain gap with foreign enterprises in battery energy management system and lithium-ion battery energy density control. The relevant person in charge of Baic Bluepark New Energy Technology Co.Ltd(600733) emphasized the chip link and mentioned that the Shanxi Guoxin Energy Corporation Limited(600617) automobile industry still needs to innovate and catch up in the key links of the chip and other industrial chains.
The person in charge told the reporter of China Electronics News that on the one hand, enterprises should pay attention to the construction of R & D system, continue to increase R & D investment and consolidate their leading advantages in three electricity technology; On the other hand, we should explore and complement each other with other companies in vehicle architecture, intelligent networking and intelligent driving, so as to create a cross industry chain automobile ecosystem and form an aggregation effect.
The second problem is the imperfect 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 still lags behind. In 2020, it is planned to build about 500000 public charging piles, 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, the utilization rate of public charging piles is low, the sustainable business development model has not been formed, and there is a two-way contradiction between the profitability of operating enterprises and the high charging price of consumers.
Based on this, Xie Nan believes that it is necessary to strengthen the construction of fast charging pile and increase the application of silicon carbide power devices in electric drive system and charging pile. We should also actively introduce intelligent management module, optimize charging order, and pay attention to the construction of community charging piles and private charging piles.
The third problem is that the post market circulation service system needs to be improved. The person in charge of Baic Bluepark New Energy Technology Co.Ltd(600733) told the reporter of China Electronics News that in terms of after-sales service, the warranty contents of new energy vehicles of different brands are uneven, the policy of replacing old batteries with new ones is also different, and the supporting system of after-sales service lags behind, which has a certain negative impact on cultivating the consumer market. At the same time, the lack of evaluation standards for the used car market of new energy vehicles, imperfect circulation system and low vehicle maintenance rate will affect the long-term development of the market.
"This requires the main engine factory to pay more attention to after-sales service and establish the concept of \'household enterprise\'. It also needs to establish industry norms as soon as possible, correctly evaluate the value of second-hand cars and promote the healthy and sustainable development of the industry." The person in charge told reporters.
