"If someone tells you that this car can run 1000 kilometers, it can be fully charged in a few minutes, it's very safe, and the cost is very low. In terms of current technology, he must be a liar. " Vice chairman of China electric vehicle 100 people association, academician of Chinese Academy of Sciences < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E6%AC%A7%E9%98%B3%E6%98%8E%E9%AB%98 "> Ouyang Minggao < / a > shocked four people at the above forum. < / P > < p > < strong > 1000 km driving range has become the focus of the industry < / strong > < / P > < p > recently, 1000 km driving range has become the focus of the new energy vehicle industry. On January 15, GAC e'an released a poster saying that its model equipped with graphene based super fast charging battery can charge 80% in 8 minutes, and NEDC standard driving range reaches 1000 km; on January 13, Zhiji automobile announced that its first model will cooperate with Ningde times, carrying "silicon doped lithium" battery, and the maximum driving range will exceed 1000 km; on January 9, Weilai automobile released 150kwh solid-state battery State battery, said the car equipped with the battery, NEDC range can reach 1000 km. < / P > < p > after years of development, new energy vehicles still have mileage anxiety, so driving range has become a selling point of new energy products. But with the current power battery technology, can 1000 km range or 80% charging in 8 minutes really become a reality? < p > < p > January 16, in China < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E7%94%B5%E5%8A%A8%E8%BD%A6 "> electric car < / a > on the forum of 100 people's Congress (2021), Ouyang Minggao said:" if someone tells you that this car can run 1000 kilometers, can be fully charged in a few minutes, is very safe, and the cost is very low. In terms of current technology, he must be a liar. " < p > < p > Ouyang Minggao believes that the current human society is in the third energy revolution with batteries as the core, renewable energy as the main body, electricity and hydrogen as the carrier, and electric vehicles as tools. Electrification is a major technological change of automobile power in the past century, and lithium-ion battery is a major revolution of energy utilization in the past century. Ouyang Minggao said that for new energy vehicles, the core technology of high-efficiency thermal management system has made an important breakthrough, which will reduce the mileage loss by 2 / 3 compared with the existing models in low temperature environment in winter, and the energy efficiency optimization and integration technology of the whole vehicle has also made a breakthrough, and the power consumption of small pure electric motor cars is close to 10 kwh in NEDC condition test. At the same time, the construction of charging system and the breakthrough of fast charging technology, in the next 5-10 years, the day can use 15 minutes to fill 75% of the electricity. According to Ouyang Minggao's research, the price of photovoltaic power generation in renewable resources is equivalent to that of coal-fired power; the scale of distributed energy is formed; various charging technologies in charging infrastructure are mature and compatible, and the infrastructure is relatively popular to meet the demand of electric vehicles; the V2G mainstream technology and mainstream business model suitable for China's national conditions in energy Internet are formed, and the business form has entered a growth period. < / P > < p > "with the help of various technological breakthroughs, new energy vehicles are about to usher in a key turning point of all-round breakthroughs." Ouyang Minggao said. < / P > < p > in addition, after Weilai automobile released 150kwh solid-state battery, solid-state battery has become a hot topic. Some people think that lithium-ion batteries have reached the limit, and solid-state batteries can inherit the status of lithium-ion batteries. However, due to the problems of hard to thin solid electrolyte and high cost of rare metal raw materials, solid-state batteries are still far from large-scale application. < / P > < p > "from the current laboratory results, the characteristics of solid-state battery such as high energy density and good safety can be demonstrated, but there is still a certain distance between laboratory results and commercial products, including performance, reliability, cost and other factors." Liang Rui, vice president of xinwanda, believes that the commercialization of solid-state batteries may need to wait until 2030. If it is successful, it should be commercialized between 2025 and 2030. < p > < p > in the research report, industrial securities also believes that at present, only semi-solid battery can be used first, that is, adding the composition of solid electrolyte in the liquid electrolyte, retaining the previous electrolyte and diaphragm, and adding the composition of solid electrolyte at the same time. It is estimated that the cost of the battery will increase by more than 100%. According to Wan Gang, vice chairman of the Chinese people's Political Consultative Conference and chairman of the China Association for science and technology, new energy vehicles have entered a new stage driven by both market and policy. The new energy vehicle market is becoming more and more diversified. At the same time, new energy vehicles are also concerned in the capital market, and the output value of new energy vehicle enterprises is growing rapidly And promote cross-border investment in other fields. < / P > < p > Miao Wei, deputy director of the Economic Committee of the National Committee of the Chinese people's Political Consultative Conference, also believes that the development of automobile electrification, intelligence and networking is the general trend. The integration of automobile, electronic information communication, transportation, energy and other fields is accelerating, and the automobile industry is in the strategic opportunity period of transformation and upgrading from big to strong. < / P > < p > "at present, the problems that people worry about, such as difficult charging and short driving range of electric vehicles, will become the past in five to eight years. In the future, what will benefit the society and deeply change people's travel experience is digitization, networking and intelligence, which is also the focus of future competition. " Chen Qingtai, chairman of China electric vehicle 100 people association, said. < p > < p > Xiao Yaqing, Minister of the Ministry of industry and information technology, believes that looking forward to the future, how to optimize the layout of the new energy industry and better maintain the smooth supply chain has become a key question that the whole industry must answer. Based on this, the Ministry of industry and information technology, together with relevant departments, will do a good job in the following five aspects: implementing the action of strengthening and supplementing the chain, speeding up the tackling of key problems of core technology, increasing the promotion and application, optimizing the industrial development environment, and deepening high-level open cooperation.
