At the moment, new energy vehiclesmarketIt is developing rapidly.
From January 15th to January 17th, the China Electric Vehicles Forum (2021) was held in Beijing for the first time online. “If someone tells you, this car can run 1,000 kilometers, can be fully charged in a few minutes, it is safe, and the cost is very low. With the current technology, he must be a liar.” Vice President of China Electric Vehicles Association, Ouyang Minggao, an academician of the Chinese Academy of Sciences, shocked four people at the aforementioned forum.
1000 km cruising range has become the focus of the industry
Recently, 1,000 kilometers of cruising range has become a new energy sourceAutomobile industryThe focus of attention. On January 15, GAC Ion released a poster saying that its models equipped with graphene-based super fast rechargeable batteries can charge 80% in 8 minutes, and the NEDC standard cruising range reaches 1,000 kilometers. On January 13, Zhiji Automobile announced its first Models andNingde eraCarry out cooperation, equipped with “silicon-doped lithium supplement” battery, the maximum cruising range will exceed 1,000 kilometers; January 9,Wei LaiThe car released a 150kWh solid-state battery, claiming that models equipped with this battery have a NEDC battery life of 1,000 kilometers.
Although new energy vehicles have been developed for many years, they still have mileage anxiety. Therefore, the cruising range has become a new energy brand for car companies.productOne of the selling points. But with the current power battery technology, 1,000 kilometers of cruising range, or 80% charging in 8 minutes, can it really become a reality?
On January 16, Ouyang Minggao said at the China Electric Vehicles Forum (2021): “If someone tells you, this car can run 1,000 kilometers, it can be fully charged in a few minutes, it is safe, and the cost is very low. With current technology, he must be a liar.”
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 energy as carriers, and electric vehicles as tools. Electricity is a major technological change in automobile power over the past century, and lithium-ion batteries are a major revolution in energy utilization over the past century.
Ouyang Minggao said that for new energy vehicles, an important breakthrough has been made in the core technology of high-efficiency thermal management systems, which will reduce the cruising range loss in the winter low temperature environment by 2/3 compared with the existing models, and the integration technology of vehicle energy efficiency optimization has also been achieved. A breakthrough, the power consumption of a small pure electric vehicle in NEDC working condition test is close to 10 kWh per 100 kilometers. At the same time, the charging system construction and fast charging technology breakthroughs, in the next 5-10 years, 75% of the electricity can be charged in 15 minutes during the day.
Ouyang MingQualcommAccording to research, among renewable resourcesPVpriceEquivalent to coal power; distributed energy forms a scale; various charging technologies in the charging infrastructure are mature and compatible, and the infrastructure is relatively popular to meet the needs of electric vehicles; energythe InternetV2G mainstream technology and mainstream suitable for China’s national conditionsbusinessThe model is formed and the business format enters the growth period.
“With the help of various technological breakthroughs, new energy vehicles are about to usher in a key turning point for all-round breakthroughs.” Ouyang Minggao said.
In addition,Wei LaiAfter the automobile released the 150kWh solid-state battery, the solid-state battery became a hot topic. There is a view that lithium-ion batteries have reached their limits, and solid-state batteries can inherit the status of lithium-ion batteries.However, due to the existence of solid electrolyte in solid-state batteries, it is difficult to thin and light, rare metalsRaw materialsProblems such as high cost are still a long way from large-scale applications.
“From the current laboratory results, the characteristics of solid-state batteries such as high energy density and good safety can indeed be demonstrated, but there is still a certain distance between laboratory results and commercial products, including factors such as performance, reliability, and cost. .”Xinwangdavice presidentLiang Rui believes that the commercialization of solid-state batteries may have to wait until 2030, and if it goes well, commercialization should be achieved between 2025 and 2030.
Industrial SecuritiesinResearch reportChina also believes that at present, only semi-solid batteries can be used first, that is, the solid electrolyte is added to the liquid electrolyte, the previous electrolyte and separator are retained, and the solid electrolyte is added. It is expected that the cost of the battery will increase by more than 100% .
New energy vehicles enter the dual driving stage of market and policy
Wan Gang, vice chairman of the National Committee of the Chinese People’s Political Consultative Conference and chairman of the China Association for Science and Technology, believes that 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 receiving attention in the capital market. carenterpriseThe rapid growth of output value has promoted cross-border investment in other fields.
National CPPCC EconomyCommitteeDeputy Director Miao Wei also believes that the development of electrification, intelligence, and connectivity of automobiles is the general trend.digital informationcommunication,traffic, Energy and other fields are accelerating integration.industryIt is in a period of strategic opportunities for transformation and upgrading from big to strong.
“The current concerns about the difficulty of charging electric vehicles and the short cruising range will become the past in 5 to 8 years. In the future, the car will benefit the society and profoundly change people’s travel experience is digitization, connectivity and intelligence. This is also the focus of future competition.” said Chen Qingtai, chairman of the China Electric Vehicles Association of 100.
industryXiao Yaqing, minister of the Ministry of Information Technology, believes that looking to the future, how to optimize new energyIndustrial Distribution, Better maintainsupply chainSmoothness has become a key question that the entire industry must answer.Based on this, the Ministry of Industry and Information Technology will work with relevant departments to implement the chain-strengthening action, accelerate key technology research, increase promotion and application, and optimizeIndustrial DevelopmentEnvironment and the five aspects of deepening high-level open cooperationjobs。
“At present, the domestic automobile cycle is more smooth, the market consumption potential is continuously released, and the automobile consumption environment is further optimized. The automobile consumption management is gradually shifted from purchase management to use management. China’s automobile consumption will continue to grow. With the continuous expansion of middle and high income groups, the new foundation Facilities are gradually improved, green and low-carbon life is widely popularized, and consumption of new energy and smart cars will gradually expand.” said Lin Nianxiu, deputy director of the National Development and Reform Commission.
It is worth noting thatBYDLimited sharesthe companyChairman Wang Chuanfu believes that 2021 will be the first year of the rapid development of the popularization of electric vehicles in China. Continue to improve the safety regulations and standards of electric vehicles, enhance the predictability of double-point prices, establish a point pool management mechanism, and electric private cars require plug-in electricity. Problems such as the two-pronged approach of hybrid and pure electric still need to be resolved.
In addition, popularizing the construction of charging facilities and accelerating the expansion of profitability have also become the focus of discussion in this forum. For example, the chairman of BMW Group Liptzer proposed to continue to resolutely promote key projects such as the construction of charging infrastructure;Changan AutomobileChairman Zhu Huarong believes that new energy vehicles urgently need to explore new profit models andbusiness model。
Challenges to achieve “carbon neutrality”
With the gradual tightening of carbon emission policies on a global scale, “carbon neutrality” has become the current hot word.
In this regard, Xiao Yaqing believes that the development of new energy vehicles is the only way for my country from a major automobile country to a powerful automobile country, and is an important part of achieving the goal of carbon neutrality and carbon peaking.
Cai Tuanjie, deputy director of the Department of Transportation Services of the Ministry of Transport, believes that from the general laws of developed countries, the carbon peak time of the transportation industry often lags behind the country’s overall carbon peak time. To this end, the transportation industry will promote green and low-carbon development from the four major aspects of prioritizing the development of urban public transportation, the low-carbonization of freight logistics, the promotion and application of new energy vehicles, and the low-carbon operation of the road network.
At present, in response to carbon emission policies, car companies including Audi and BMW have set targets for reducing carbon dioxide emissions. For example, the BMW Group plans to provide 25 electric models in the global market by 2023, and by 2030, its single-car carbon dioxide emissions will be reduced by at least one third compared with 2019.
Chiptzer stated at the aforementioned forum that BMW will fully support China in achieving its goal of “striving to achieve carbon neutrality by 2060”. “In 2021, the BMW Group plans to sell 100,000 pure electric vehicles worldwide.” In Kiptzer’s view, only whenclientElectric travel can only be successfully promoted when you can enjoy charging services anytime, anywhere.
As of the end of 2020, BMW has deployed 300,000 public charging piles in the Chinese market. At the same time, BMW’s first charging-light-storage integrated energy demonstration station has been completed and put into operation in Beijing.
In addition to China, many countries including Japan and South Korea have recently proposed the latest targets to reduce carbon dioxide emissions.
Faced with the Korean government’s 2050 carbon neutral plan, Li Guangguo, President of Hyundai Motor Group China, said: “Hyundai plans to expand its electric vehicle product lineup in the global market this year. The goal is to launch 23 electric vehicle models by 2025. Reach 1 million; by 2030, it is expected to sell about 500,000 hydrogen fuel cell vehicles and 700,000 hydrogen fuel cells; by 2040, fully electrified.”
Although car companies have already put forward the goal of carbon neutrality, in the view of Xie Feng, executive vice president of strategy and business development of Jaguar Land Rover (China) Investment Co., Ltd., compared with the current new energy applications for bicycles promoted by many car companies, the realization of carbon Neutralization still poses great challenges.
“Achieving carbon emissions targets requires the government to play a greater role. For example, the concept of “smart city” proposed by China solves this problem well, because only when the entire city becomes smarter, the city’s operating facilities become more environmentally friendly. Friendliness, the efforts of bicycles and the efforts of each consumer in travel can truly achieve all carbon emission targets.” Xie Feng believes.
When car companies collectively “decarbonize”, problems will follow. In this regard, Xiao Yaqing believes: “Focusing on the goal of carbon peaking and carbon neutrality, the Ministry of Industry and Information Technology will work with relevant departments to study and formulate a technical roadmap for the implementation of the automotive industry. At the same time, we will resolutely curb blind investment and avoid inefficient duplication. Construction.”
