Now all countries are vigorously developing fuel-powered 18650 li ion rechargeable battery passenger cars, and some domestic experts have called for strengthening the support for fuel-powered lithium batteries. So, where is the breakthrough point of my country's fuel-powered 18650 li ion rechargeable battery vehicles? The following is the content about the breakthrough point of my country's fuel-powered 18650 li ion rechargeable battery vehicles brought by the editor, hoping to make everyone gain something!

Fuel-powered 18650 li ion rechargeable battery vehicles in Europe and the United States attach importance to the development of fuel-powered 18650 li ion rechargeable battery passenger cars, especially the recent news that the Japanese government has vigorously developed hydrogen energy has attracted widespread attention. After seeing this news, some domestic experts have called for strengthening the support for fuel-powered lithium batteries. As the commanding heights of future automobile development, where is the breakthrough point of my country's fuel-powered 18650 li ion rechargeable battery vehicles? Some experts believe that my country should start with commercial vehicles, and the current route of vigorously developing fuel-powered 18650 li ion rechargeable battery buses is in line with my country's reality.

my country attaches great importance to the development of fuel-powered 18650 li ion rechargeable battery vehicles and gives high subsidies to fuel-powered 18650 li ion rechargeable battery vehicles. Under the general trend of declining subsidies for electric vehicles, subsidies for fuel-powered lithium batteries have not been affected and the original subsidy intensity has been maintained.

"Made in my country 2025" clearly proposes to support the development of fuel-powered 18650 li ion rechargeable battery vehicles and promote the development strategy of self-owned brand energy-saving and new energy vehicles to meet the international advanced level. It plans three development stages: the first is to gradually realize the localization of key materials and components; the second is to gradually improve the performance of fuel-powered lithium batteries and battery stacks; the third is to achieve the expansion of the operating scale of fuel-powered 18650 li ion rechargeable battery vehicles to 1,000 vehicles in 2020, and the basic completion of supporting infrastructure such as hydrogen production and hydrogenation by 2025.

Chen Linxin, senior consultant of the National Hydrogen Energy Standard Technical Committee, said that my country's hydrogen energy development has gone through the "conceptual" stage and entered the stage of industrialization.

Recently, the research results of the Western Securities team also confirmed Chen Linxin's point of view. Shen Wei, an automotive industry analyst at Western Securities, said: "Recently, we have visited my country's fuel power 18650 li ion rechargeable battery industry chain again. Compared with the past, the products have stepped out of the laboratory and entered the demonstration operation stage."

On August 25, 2017, SinoHytec's first hydrogen fuel power 18650 li ion rechargeable battery engine was officially launched at the Zhangjiakou hydrogen fuel power 18650 li ion rechargeable battery engine production base, marking the official launch of my country's first self-developed automated hydrogen fuel power 18650 li ion rechargeable battery engine mass production line.

At the end of 2017, SAIC Motor launched the 6-meter FCV80 and began commercial operation in Shanghai and Fushun, Liaoning, with a scale of about 100 vehicles. This is the first truly commercial fuel power 18650 li ion rechargeable battery product, marking that fuel power 18650 li ion rechargeable battery products have stepped out of the laboratory and entered the industrialization stage.

In order to promote the development of fuel power lithium batteries, the Ministry of Science and Technology has also actively promoted the industrialization of fuel power 18650 li ion rechargeable battery vehicles. Wan Gang, Minister of Science and Technology, has repeatedly pointed out that in the field of automotive energy, fuel power 18650 li ion rechargeable battery engines will become an important direction for the future transformation of automotive power electrification.

The Ministry of Science and Technology has recently set a goal to support the development of fuel-powered lithium batteries, striving to build a 100,000-set fuel-powered 18650 li ion rechargeable battery industrial base by 2022, realize the application of 10,000-set fuel-powered 18650 li ion rechargeable battery engines, and complete the promotion and application of 1,000-level vehicles. In terms of organizational form, the government will guide, the company will participate, and the investment will be diversified. It is estimated that the total R&D cost of hydrogen fuel-powered 18650 li ion rechargeable battery electric vehicles will exceed 5 billion yuan.

Europe and the United States attach importance to the development of fuel-powered 18650 li ion rechargeable battery passenger cars. How should my country seek breakthroughs? Qian Wei, deputy general manager of Chunhua Hydrogen Energy, said that starting from my country's actual situation, starting from the commercial vehicle field, we should seek breakthrough opportunities.

The power of Toyota Mirai is 115 kilowatts, and the technical level of my country's fuel-powered 18650 li ion rechargeable battery stacks has not reached such a high level. Qian Wei said: "If the domestic fuel-powered 18650 li ion rechargeable battery stack reaches 115 kilowatts, the volume is relatively large and cannot be accommodated in passenger cars. Commercial vehicles are less sensitive to the volume of fuel-powered 18650 li ion rechargeable battery stacks. Under current technical conditions, it is more suitable for my country to promote fuel-powered 18650 li ion rechargeable battery vehicles from commercial vehicles."

The popularity of traditional fuel vehicles has a lot to do with the dense distribution of gas stations. The promotion of fuel-powered 18650 li ion rechargeable battery vehicles is inseparable from the construction of hydrogen refueling stations. However, the construction of domestic hydrogen refueling stations faces two difficulties. One is that people do not have enough understanding of the safety of hydrogen; the other is that it is difficult to find land for the construction of hydrogen refueling stations in cities.

In recent years, news of children being injured by hydrogen balloons has been reported frequently in newspapers, making people very worried about the safety of hydrogen. This phenomenon exists not only among citizens, but also among many local leaders. Mao Zongqiang, vice chairman of the International Hydrogen Energy Association and professor at Tsinghua University, said: "As long as it is properly operated, hydrogen is not dangerous. In addition, the specific gravity of hydrogen is very small and it is extremely volatile. If there is a slight leak at a hydrogen refueling station, it will immediately evaporate into the atmosphere and will not gather at the hydrogen refueling station to explode."

Gas stations are densely distributed in every corner of the city. Passenger car owners are accustomed to refueling nearby. However, urban land resources are very tight, especially in large cities. There is no extra land available for the construction of hydrogen refueling stations. In addition, in order to meet safety standards, the area of hydrogen refueling stations must be large, and it is even more difficult to find such land in the city. "If hydrogen refueling cannot be done nearby, fuel-powered 18650 li ion rechargeable battery passenger car owners will feel very inconvenient, which greatly reduces their enthusiasm for purchasing." Qian Wei said, "Building hydrogen refueling stations in the suburbs will solve the problem of insufficient understanding of hydrogen safety and land resources."

Most of the parking lots for urban buses in my country are in the suburbs. If hydrogen refueling stations are built in the suburbs, fuel-powered 18650 li ion rechargeable battery buses can refuel nearby. In addition, freight vehicles running around all over the country pass through the outskirts of the city, and building hydrogen refueling stations in the suburbs will also facilitate the refueling of fuel-powered 18650 li ion rechargeable battery freight vehicles.

Another industry expert said that the power characteristics of fuel-powered lithium batteries are relatively good and can supply energy to vehicles for a long time. This characteristic is destined to be more suitable for large commercial vehicles.

The cleanliness of hydrogen energy is self-evident. All countries want to gain a leading advantage, and starting with commercial vehicles is more in line with my country's actual situation.
