Global new energy vehicle technology upgrade accelerates the rapid increase of power battery energy density

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 investigate the development of new energy automobile industry and technology in Zhejiang Province and asked for the diagnosis of the new energy automobile industry.

Li Jun, an academician of the Chinese Academy of Engineering and chairman of the China Automotive Engineering Society, said that in recent years, global new energy vehicle technology upgrades have accelerated, and automobile complete vehicles and key component technologies have developed rapidly, showing a platform-oriented, modular and lightweight trend. For example, the energy density of power batteries is rapidly increasing. The energy density of mass-produced power batteries is basically 230-260 watt-hours/kg, and the technical reserve of 300 watt-hours/kg of power batteries is completed, and the cost of single-cell batteries is greatly reduced.

According to experts, the current world automotive industry's electrification strategy is becoming clearer, and major countries have stepped up their efforts to electrify cloth. Norway, the Netherlands, Germany, and other countries are even planning a comprehensive electrification schedule. Major global automobile manufacturers have also announced new development plans for new energy vehicles.

With the deepening of the new round of scientific and technological revolution, automobile technology and the Internet, big data, artificial intelligence and other accelerated integration, while the car is electrified, it also presents the development trend of intelligence, network, and sharing. Li Jun believes that "smart shared mobile travel is expected to become the future development direction, and may reshape the automobile industry ecology and competition."

In Zhejiang Province, a large number of enterprises such as Geely, Zotye, and Wanxiang have entered the field of new energy vehicles. Some Internet companies have also entered the automobile industry, which has driven the development of the ecological chain of new energy vehicles. In 2017, the new energy vehicles in Zhejiang Province The output is about 82,000, accounting for 10.3% of the country, and the output is among the highest in the country. The industrial chain covers key components such as new energy vehicles, key components such as power batteries, core basic materials, and charging facilities, and has made many explorations in the intelligent sharing of new energy vehicles and business models.

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

Under the wave of digital transformation in the automotive industry, auto companies are gradually shifting from single-supply to automotive products to travel services. Li Jun believes that intelligent new energy vehicles are expected to become the basic unit of intelligent transportation and smart cities. It is recommended that Zhejiang Province actively promote the integration of automotive electrification, intelligence, and sharing, and to intelligently share the behavior platform in the future, to drive the Internet, big data. , cloud computing, artificial intelligence, and other travel services and new industries related to passenger economy.

In 2018, it was defined by the industry as the “kinetic energy conversion year” for the development of new energy vehicles in China. Experts said that in the future, the country will adjust the industrial structure of the whole vehicle and power battery. This means that there will be a process of survival of the fittest, and relevant enterprises should pre-empt the situation and see the direction. Private enterprises in Zhejiang are very active in the field of new energy vehicles. If they want to avoid being eliminated by the market and industry, they must rely on the characteristics to win in the market.
