Global new energy vehicle technology upgrades are accelerating, and the energy density of power lithium batteries is rapidly increasing

　　New energy vehicles have become the choice of more and more people to buy cars, and their industrial development has also entered the fast lane. A few days ago, the China Association for Science and Technology organized experts to Zhejiang Province to investigate the development of the new energy automobile industry and technology, and to gauge the development of the new energy automobile industry.

　　Li Jun, academician of the Chinese Academy of Engineering and chairman of the China Society of Automotive Engineers, said that in recent years, global new energy vehicle technology upgrades have accelerated, and vehicle and key component technology has developed rapidly, showing trends in platformization, modularization, and lightweighting. For example, the energy density of power batteries has increased rapidly. The energy density of mass-produced power batteries has basically reached 230-260 Wh/kg, and the technical reserve of 300 Wh/kg power batteries has been completed. The cost of single batteries has dropped significantly.

　　According to experts, the current electrification strategy of the world's automobile industry is becoming increasingly clear, and major countries have strengthened their electrification layout. Norway, the Netherlands, Germany and other countries are even preparing a timetable for full electrification. Major global automobile manufacturers have also successively released new new energy vehicle development plans.

　　With the deepening of the new round of technological revolution, the integration of automotive technology with the Internet, big data, artificial intelligence, etc. is accelerating. While cars are becoming electrified, they are also showing a development trend of intelligence, networking, and sharing. Li Jun believes that "smart shared mobility is expected to become the future development direction and may reshape the automotive industry ecology and competition landscape."

　　In Zhejiang Province, a large number of companies such as Geely, Zotye, and Wanxiang have entered the field of new energy vehicles, and some Internet companies have also entered the automobile industry, driving the development of the new energy vehicle industry ecological chain. In 2017, Zhejiang Province produced about 82,000 new energy vehicles, accounting for 10.3% of the country's total, and its output ranks among the top in the country. The industrial chain covers new energy vehicles, key components such as power batteries, core basic materials, charging facilities and other key links, and has made a lot of explorations in new energy vehicle intelligent sharing and business models.

　　In Li Jun's view, fuel cells are the commanding heights of future technological competition in the automotive industry. However, Zhejiang Province lags behind in the research and development, demonstration and promotion of hydrogen fuel cell vehicle technology, and it is recommended to strengthen the strategic layout of the fuel cell industry. On the one hand, we will strengthen support for the research and development of hydrogen fuel cell vehicles and cultivate the industrial chain; on the other hand, we will jointly promote the construction of the Yangtze River Delta hydrogen corridor and the development of hydrogen fuel cell vehicles by launching demonstration and promotion work for fuel cell vehicles and forming regional linkages with Shanghai, Jiangsu and other provinces and cities. Economic Integration.

　　Under the wave of digital transformation in the automobile industry, automobile companies are gradually transforming from solely providing automobile products to traveling services. Li Jun believes that smart new energy vehicles are expected to become the basic unit of smart transportation and smart cities. He recommends that Zhejiang Province actively promotes the integration of vehicle electrification, intelligence, and sharing, and uses future smart shared travel as a platform to drive the Internet and big data. , cloud computing, artificial intelligence and other new industries related to travel services and passenger economy.

　　2018 is defined by the industry as the "Year of Momentum Conversion" for the development of new energy vehicles in China. Experts said that in the future, the country will adjust the industrial structure of complete vehicles, power batteries, etc., which means there will be a process of survival of the fittest, and relevant companies should make arrangements in advance and see the direction clearly. Private enterprises in Zhejiang are very active in investing in the field of new energy vehicles. If they want to avoid being eliminated by the market and industry, they must rely on their characteristics to win in the market.
