The whole process is 1262 kilometers, with an average one-way fast charging station every 50 kilometers. The electric car can be filled in as fast as 30 minutes. According to the State Grid, the full-line rapid charging system of Beijing-Shanghai Expressway has been completed and will be opened soon.
On the morning of January 11, five electric vehicles departed from Shanghai to Beijing to start the long-distance "breaking ice" journey of electric vehicles. According to media reports, according to the average 150-200 km charging calculation, the electric car only needs to be charged 6 to 7 times, and each time it is charged 30 degrees, it can be opened from Shanghai to Beijing; the price of electricity is 0.65-0.8 yuan per degree, and the whole charging cost is not To 400 yuan, the same mileage electricity expenses are only half of the fuel vehicles.
"Construction of charging and replacing facilities is a key factor in accelerating the development of the electric vehicle industry." Zhang Jinhua, executive vice president and secretary general of the China Automotive Engineering Society and secretary general of the Strategic Alliance for Electric Vehicle Industry Technology Innovation, said in an interview with the Science and Technology Daily reporter that Beijing The completion of the fast-charging system of the Shanghai Expressway has brought good news to the production and sales of electric vehicles. "With the fast-filling stations along the expressway, electric vehicles can also come to the trip of 'go away and go'."
The automotive industry is not sustainable without changing the energy consumption structure
On January 12, the China Automobile Industry Association released data showing that in 2014, China's automobile production and sales both exceeded 23 million, a record high in the world, and ranked first in the world for six consecutive years.
"At present, the annual production and sales volume of China's automobiles will continue to grow at a rate of 6% to 10% within 15 years." Zhang Jinhua said that for developed countries in Europe and America, automobile production has become saturated. With the development of automobile technology, The energy consumption level is declining, and the energy consumption brought by automobile production and use in China has the characteristics of high total and rapid growth, which affects the country's energy security.
"Automobiles are consumer goods that are inseparable from everyone in modern society. From the perspective of social economy, the automobile industry has contributed a huge amount of output value, and at the same time, the driving effect on related industries is also very obvious." Zhang Jinhua believes that "in the face of energy, Environmental constraints, simple 'limited production' 'restricted' does not solve the problem."
On the one hand, the status of the pillar industry is unshakable, and on the other hand, the pressure on the energy environment is unbearable. "If you do not change the energy consumption structure of the car, the automotive industry will not be sustainable." Zhang Jinhua said, "For China, the urgency of this change is stronger than any other country."
World-class market, more world-class technology
"Using electric vehicles, or new energy vehicles as a technical route, to solve the problems faced by the development of the automotive industry is an international consensus." Zhang Jinhua said in an interview with the Science and Technology Daily reporter that as the world's largest and the first to start the electric vehicle market, China's Development affects the trends and patterns of the world's electric vehicle industry.
In 2001, the National 863 Program launched a major special project for electric vehicles, and technology first opened the prelude to the development of China's electric vehicle industry. After more than ten years of hard work, the domestic sales of new energy vehicles reached 74,800 units in 2014. China will surpass Japan, the second largest in the world, for the first time, becoming the world's second largest new energy vehicle market. In the first 11 months of the year, the sales of pure electric vehicles reached 29,060 units, a year-on-year increase of 7 times; the plug-in hybrid vehicles sold 23,884 units, a year-on-year increase of 25 times.
Faced with the technological development of electric vehicles and the current market achievements, Zhang Jinhua believes that this benefits from the "up and down emphasis", but it is undeniable: "Because of the weak industrial base and insufficient investment in innovation, China's electric vehicle industry as a whole There is still a large technological gap in the world's advanced level."
At the end of 2010, the Strategic Alliance for Technology Innovation of the Electric Vehicle Industry (hereinafter referred to as the “Allianceâ€) was established. “All along, the domestic electric vehicle industry is constantly carrying out low-level 'repetitive labor'.†As the Secretary-General of the Alliance, Zhang Jinhua believes that “the establishment of alliances is to concentrate on superior resources and form a joint effort to tackle common problems in order to shorten our industrial technology. difference."
Serving the whole vehicle enterprise as the core, common demand-oriented
In order to shorten the technological gap in the electric vehicle industry, the alliance has targeted the entire vehicle enterprise. In 2010, SAIC, FAW, Changan, Chery, Geely, and Jianghuai became the core members of the alliance to discuss the agreed technical needs. In the first phase of the alliance, each invested 3 million yuan in research and development funds. Refining has become a scientific research subject, supported by corporate investment and funding from relevant national projects, organized corresponding research and development institutions to carry out research, and shared six innovation achievements.
"The core task of the alliance is to serve the whole vehicle enterprise. We will place orders according to the needs of the whole vehicle enterprise." Unlike many alliances, the electric vehicle alliance chooses the technical research and development commitment, not limited to alliance members, Zhang Jinhua explained. "The Alliance adheres to the principle of openness and optimization, and concentrates on the most advantageous resources in the industry to carry out technical research."
This cooperative R&D mechanism of “common demand-oriented, joint investment, and shared results†was affirmed in the acceptance of the 863 program “Research and Development of the Next Generation High-Performance Pure Electric Car Power System Technology Platform†undertaken by the Alliance. The acceptance expert group put forward this topic to take the electric vehicle industry technology innovation strategic alliance as the main body, explore the formation of cooperative research and development mechanism, build a resource sharing platform within the alliance and cross-industry cooperation research platform, and promote cooperation and research in production, education and research. R&D efficiency and accelerated technological breakthroughs have played an important role.
In the new round of research and development cycle that will begin this year, this cooperation mechanism will continue to move forward. Zhang Jinhua told the Science and Technology Daily reporter that for the whole vehicle and platform units of the alliance, it is still necessary to promise 3 million yuan for the joint technology research of the alliance during 2015-2017. The specific research topics will be started according to the actual needs; The key component projects aiming at industrialization must be promised to return to the alliance from the industrialization income within 50% of the industrialization income within 5 years after the completion of the project, for the follow-up common technology research of the alliance. "The rate of return will increase in the future." Zhang Jinhua said.
Platform prototypes, key components and research and development go hand in hand
At present, the Alliance has completed two platforms for centralized drive and distributed drive. According to reports, the centralized drive platform prototype undertaken by Tianjin Qingyuan Electric Vehicle Co., Ltd. integrates braking energy recovery, heat pump air conditioning system, cruising range estimation and other technologies, achieving an acceleration of less than 11 seconds per 100 kilometers, ECE urban conditions The power consumption of 13.9kWh is 100 kilometers.
The more forward-looking model of the distributed drive technology platform was undertaken by China Automotive Engineering Research Institute Co., Ltd., using the structure of the front wheel motor and the rear hub motor to complete the test of the stability and smoothness of the hub motor to the vehicle. the study.
"For China's entire automotive industry, the parts system is a weakness, and electric vehicles are no exception." Zhang Jinhua said that the alliance has locked in a number of key components and common technology development research, and made important progress. Among them, a ternary material power battery cell researched and developed by BAK International (Tianjin) Co., Ltd. has an energy density of 180Wh/kg; a motor developed by Jingjin Electric Technology (Beijing) Co., Ltd. has a power density of 4.3kW/ Kg, the speed reaches 12000rpm, the highest efficiency reaches 96%. “These technical indicators have reached the domestic advanced level.â€
Zhang Jinhua introduced that from 2014 to 2017, the alliance will collect the technical difficulties of each member unit, combine the difficulties of technology development, comprehensively consider the positioning of the alliance and the applicability of technology, and plan to raise funds of 550 million yuan to carry out the alliance. The second-stage research and development work will focus on breaking through the energy-saving key components of brake energy recovery, heat pump air conditioning systems, special automatic transmissions, and industrialization, and develop a new competitive A-class electric vehicle with international competitiveness. The high-performance B-class pure electric car prototype has established a common basic technology platform based on vehicle-to-standard analysis and patent analysis.
Cross-industry integration, integration into the Internet begins with technology
While paying attention to the technical needs of electric vehicle manufacturers and radiating the technological development of the industry, the alliance will also look beyond the scope and carry out cross-industry cooperation research.
According to reports, the Alliance and the Shanghai Fire Research Institute of the Ministry of Public Security jointly carried out research on the technical specifications of electric vehicle fire safety, and comprehensively combed the existing standard specifications for power battery production and storage, charging and replacing power stations, and electric vehicle use at home and abroad. The outstanding problems affecting the fire safety of electric vehicles were analyzed, and the system framework of electric vehicle fire safety technical specifications was compiled to make up for the blank of electric vehicles.
In addition, in cooperation with the power grid, the Alliance carried out research on the charging mode of coordinated development of electric vehicles and power grids. Zhang Jinhua said: “Electric vehicles are generally charged at night, and when they are not on the road during the day, they can use extra power to access the Internet. The coordinated development of the charging model will be piloted in domestic cities in the near future."
Due to the success of Tesla, "we are also considering the integration with the Internet." Zhang Jinhua told the Science and Technology Daily reporter that Tesla's biggest bright spot is not the breakthrough in electric vehicle technology, but the success of using Internet thinking in market operations.
Earlier, some people in the industry said that electric vehicles have Internet genes, which can apply early innovations such as car networking and cloud services to lead the car to the Internet.
Last year, the Alliance organized a closed-door meeting of domestic automotive and related technology companies in the Internet. "I think the integration with the Internet should start with technology first," Zhang Jinhua said.
