As the next generation power system, hydrogen fuel cell came to us in a blink of an eye. On the afternoon of September 13, at the conference of "Seeing the Hydrogen Core" of SAIC Chase MAXUS, the highly self-developed SAIC hydrogen fuel cell power system and the world's first hydrogen-powered MPV model-SAIC Chase MAXUS? EUNIQ7 was officially unveiled. After carefully studying the history and technical parameters of SAIC hydrogen power research and development, I can't help but say: hydrogen, are you there? !
The origin of 20 years ago
Perhaps more people's understanding of hydrogen fuel cell technology will focus on Hyundai and Toyota brands, and SAIC has actually become attached to this ultimate technology that points to clean energy in the future as early as 20 years ago.
200 1, as the earliest automobile enterprise in China to develop fuel cell technology, SAIC started the "Phoenix No.1" fuel cell vehicle project.
Over the past 20 years, SAIC has continuously invested in tackling key problems in a down-to-earth manner, and accumulated research and development expenses have exceeded 3 billion yuan. Up to now, it has obtained the fuel cell related patent 5 1 1, and actively participated in the formulation of the national fuel cell standard 15. SAIC's "Key Technology Research and Development and Industrialization Project of Fuel Cell Vehicle" won the special prize of "China Automobile Industry Science and Technology Progress Award" in 20 19.
In the field of core technology "stack", SAIC has also incubated the listed company He Jie Science and Technology-from the core components of stack (bipolar plate, membrane electrode), stack integration and fuel cell system integration to the research and development of power system integration and vehicle integration, with completely independent intellectual property rights. It launched PROME? P390 fuel cell system, power, power density and low-temperature start-up are comparable to the world's top level represented by Toyota and Hyundai. PROME, the core component of fuel cell system? M3H reactor is completely independently designed and developed, and all 58 first-class components are localized, with the degree of autonomy and localization rate reaching 100%.
Until September 13, 2020, the world's first hydrogen-powered MPV EniQ 7 launched by SAIC Chase MAXUS was actually equipped with the third generation technology of SAIC hydrogen fuel cell. Compared with the hydrogen-powered passenger cars launched by competitors, this technology has actually surpassed a generation, "reaching the next generation technology level being developed by Japanese and Korean car companies".
SAIC's "Ten, Hundred, Thousand, Ten Thousand" Hydrogen Energy Strategy
Compared with the world premiere of SAIC Chase Unik, SAIC's hydrogen strategy is more ambitious. On the same day, Wang Xiaoqiu, President of SAIC, officially released the hydrogen strategy that SAIC will strive to achieve "10,10 billion, 10000 vehicles" in the next five years.
According to this strategy, in the next five years, SAIC will strive to achieve the four goals of "ten, one hundred, one thousand and ten thousand": at least "ten" fuel cell vehicle products will be launched by 2025;
Jiehydrogen technology has reached a market value of "100" billion;
Establish a fuel cell R&D and operation team with more than 1000 people;
The production and sales scale of "10,000" class fuel cells has been formed, and the market share is above 10%.
By 2025, SAIC's self-developed fuel cell system will achieve cumulative sales of more than 30,000 sets, becoming the leader of domestic independent fuel cell systems. By 2030, SAIC will become a fuel cell vehicle manufacturer with completely independent intellectual property rights and global competitiveness!
This ambitious strategy of SAIC has a deep realistic foundation: SAIC is the only enterprise in the global industry that has commercialized a variety of fuel cell vehicles, with a total mileage of nearly 5 million kilometers and accumulated carbon emission reduction of more than 600 tons, equivalent to planting 6,543,800+2,000 trees.
20 14, roewe 750? The fuel cell vehicle became the first fuel cell vehicle in China to realize the announcement.
In 20 16, roewe 950 fuel cell vehicle became the first fuel cell vehicle published, sold and licensed in China.
In 20 17, Datong FCV80 fuel cell light bus became the earliest and only commercialized fuel cell wide-body light bus in China.
In 20 18, Roewe 950 fuel cell car and Shenwo fuel cell bus were selected as the designated vehicles of "United Nations Development Programme (UNDP) Promoting the Commercialization Project of Fuel Cell Vehicles in China", and Shenwo fuel cell bus started commercial operation in Jiading 1 14 at the end of 20 18.
In 2020, SAIC Yuejin Fuel Cell Logistics Vehicle and Fuel Cell Special Vehicle were announced by the Ministry of Industry and Information Technology.
In June 2020, the world's first fuel cell MPV SAIC· Chase? Max? EUNIQ7 officially went offline and will be listed soon this year.
Among them, 407 SAIC Chase Max? The FCV80 fuel cell light bus has been operated in seven cities, including Shanghai, Fushun, Foshan, Dalian, Wuxi, Changzhi (Shanxi) and Qingdao, with a cumulative mileage of over 4 million kilometers. Vehicles in Fushun area encounter extremely cold weather for two months throughout the year, with the average minimum temperature below -20℃ and the extreme minimum temperature even reaching -30℃. The FCV80 fuel cell light bus runs well in general. On 20 19, FCV80 fuel cell light passengers started the operation of Wuxi Airport shuttle bus line. At present, the total mileage of vehicles exceeds160,000 km, and the passenger load rate reaches over 80%.
Is hydrogen power reliable?
Before the official press conference, the media first visited the SAIC Hydrogen Fuel Cell Technology Corridor. Here, the cycle model from the "stack" and its components, hydrogen storage equipment to the vehicle-mounted platform is complete, and each part is equipped with a dedicated person for in-depth technical explanation and question and answer.
This technology has not only passed the rigorous and durable road test and weather resistance experiment with a total mileage of more than 6.5438+00,000 kilometers and 25 laps around the earth, but also carried out various technical verifications such as collision. Through these verifications, people can rest assured of this technology.
In terms of power performance, taking EUNIQ7 as an example, this car adopts 130kW fuel cell and 70Mpa hydrogen storage system, matching high-performance three-in-one electric drive axle and domestic leading high-rate power battery. NEDC has a cruising range of 605 kilometers, and can be started at a low temperature of -30 degrees Celsius without any low temperature loss.
The hydrogen storage equipment is designed with three layers of materials and pressure relief valves, which can withstand the strength of 70mpa equivalent to that of a 7000m deep-sea submarine, while the pressure resistance of the same type of products is only half of that of-35 MPa at present.
On the other hand, EUNIQ? It also has many technical advantages, such as 3 minutes full of hydrogen fuel, low use cost of 0.4 yuan /km, and the average noise inside the car is only 53.9 decibels, which completely meets the applicable scenarios.
Red dot observation
Hydrogen fuel cell technology is called clean energy in the true sense, that is, the whole process from the generation to the use of hydrogen is completely clean. With regard to this technology, although Hyundai and Toyota respectively launched passenger car products and achieved sales of more than 3,000 units, there are still some problems in the domestic use environment, such as hydrogen refueling stations, so it is estimated that the initial output and sales will not be too large. On the other hand, people from Shanghai Science and Technology Commission who attended the conference said that there are more than a dozen hydrogen refueling stations under construction and planning in Shanghai, and this year, hydrogen refueling stations will be gradually extended to the central and inner rings of Shanghai. At the same time, Beijing has also released the "Beijing Hydrogen Fuel Cell Automobile Industry Development Plan (2020-2025)"-it can be seen that hydrogen fuel cell technology is developing at an unimaginable speed, and it is believed that hydrogen power has become the next vent of automobile enterprise technology competition, and this day seems to arrive about 5 years earlier than expected!
