Hydrogen energy is ushering in a spring of development. What are the advantages of SAIC Maxus’ “hydrogen” layout?

At the recent Qingdao International Academician Port Collaborative Innovation Achievements Display and Docking Cooperation Seminar, representatives from the Chinese Academy of Engineering, national R&D institutions, scientific research teams from well-known universities, internationally renowned academicians, and leading, backbone, and characteristic enterprises gathered here to discuss The development plan of hydrogen energy industry. For the first time, SAIC Maxus from Shanghai displayed its brand SAIC Maxus hydrogen fuel cell wide-body light bus FCV80, hydrogen fuel cell MPV G20FC engineering prototype, SAIC Yuejin fuel cell truck FC500 D12 logistics truck and dump truck, relying on technology The advantages demonstrate its leading strength in the field of hydrogen energy. Hao Jingxian, deputy chief engineer of SAIC and general manager of SAIC Maxus Technology Center, shared the development and practice of fuel cells of SAIC. The strength of the fuel cell product camp steals the spotlight. "Hydrogen energy", as a zero-pollution and efficient energy source, is gradually being used in our lives. After the hydrogen fuel reaction, only pure water is produced, which causes zero pollution to urban air during the use stage. There is nothing to be picky about in terms of environmental protection. Therefore, hydrogen energy, which has the two characteristics of "high efficiency" and "clean", is undoubtedly one of the important breakthroughs in the transformation and upgrading of vehicle fuels. However, due to technical reasons, the number of hydrogen fuel cell vehicles launched by major car companies in recent years has been very limited. It is not easy to get across the threshold of hydrogen fuel cell vehicles, and it is even more difficult to put them into production and operation. At present, the only domestic automobile group that has fully implemented the three technical routes of "pure electric, plug-in hybrid, and fuel cell" is SAIC. SAIC is also the first domestic automobile company to invest in and continue to invest in fuel cell vehicles, and it is currently the only domestic automobile group. Enterprises with technology and production capabilities for fuel cell passenger cars and commercial vehicles. While most companies are still busy with technology reserves, SAIC Maxus has made full arrangements in new energy product planning with the strong support of SAIC in terms of funds, research and development, resources, talents and other aspects. The outside world showed its "hydrogen" layout, allowing the guests to experience the green, environmentally friendly, pollution-free and zero-emission advantages of the hydrogen fuel cell wide-body light bus FCV80. It also allowed people to see that the real leading companies in this industry are developing rapidly. . As China's first commercially operated fuel cell wide-body light bus, the first fuel cell light bus model in China to apply new access standards, and the first fuel cell light bus model in the world, SAIC Maxus FCV80 has attracted much attention since its launch. , mainly used in commuter passenger transportation for industry customers. The vehicle uses a dual power source with a fuel cell system as the main system and a power battery as a supplement, with a maximum driving range of up to 500 kilometers. Fuel cells are an important technical route for SAIC Maxus to lead the development of the industry. By 2020, the peak output power of the second-generation stack system independently developed by SAIC Maxus will reach 115kw, and will be the first to be applied to medium and large MPV models. Hydrogenation time In just 3 minutes, the maximum cruising range will exceed 650km, which is almost the same as a fuel vehicle. At this seminar, the SAIC maxus g20fc engineering prototype equipped with the second-generation stack system was unveiled for the first time. The product is expected to be launched by the end of 2020. Compared with electric vehicles on the market that have short battery life, slow charging, and cannot start at low temperatures, the g20fc can achieve cold start at minus 30 degrees Celsius, and the nedc comprehensive operating range is as high as 550 kilometers. In addition to market segments such as light passenger vehicles and MPVs, SAIC Yuejin’s fuel cell trucks should not be underestimated. The SAIC Yuejin fc500 d12 fuel cell logistics vehicle and dump truck on display this time can carry up to 7 tons. It has the characteristics of rapid hydrogenation in 3 minutes, zero emissions, and a strong endurance of 500 kilometers. The energy utilization rate of the entire vehicle is 9% higher than that of pure electric vehicles. It can also meet the vehicle driving needs in the environment of -25℃~55℃. Commercial operation quality inspection As the saying goes, "the carriage and horses have not moved, but the grain and grass go first." Although the development prospects of hydrogen fuel vehicles are promising, they are currently largely restricted by insufficient infrastructure construction. Under various national policies to encourage the development of hydrogen fuel cell vehicles, the construction of hydrogen refueling stations is also gradually underway. This year the Pujiang Innovation Forum released the "Yangtze River Delta Hydrogen Corridor Construction and Development Plan". The Yangtze River Delta plans to have 5,000 hydrogen fuel cell vehicles and 40 hydrogen refueling stations by 2021. Located in the core area of ​​the "Yangtze River Delta Hydrogen Corridor", SAIC Maxus is sparing no effort to support the country's energy transformation and technological innovation, actively promote the integrated development of the hydrogen energy and fuel cell industries in the Yangtze River Delta, and lead the development of the hydrogen energy and fuel cell vehicle industries. and large-scale applications. The commercial operation territory of SAIC maxusfcv80 has been continuously expanded, and the commercial full-scenario application is used to promote the development of the hydrogen energy industry, demonstrating the confidence and strength of SAIC maxus in promoting green development and green lifestyle. In addition to Shanghai, Fushun, Foshan and Wuxi, SAIC maxus fcv80 commercial operation territory has now expanded to Dalian, Liaoning and Changzhi, Shanxi. So far, more than 400 SAIC Maxus vehicles have been demonstrated and operated in 6 cities across the country, with a total operating mileage of 3 million kilometers, which is equivalent to circling the earth 75 times. In the Shanghai Chemical Industry Zone, fcv80 is used as a commuter shuttle to provide enterprises with more convenient and environmentally friendly travel services; in Fushun, Liaoning, fcv80 has launched commercial operations on public roads, including three township small passenger lines and a county-wide tourist charter bus, each The daily driving mileage is more than 100 kilometers, the low-temperature operation time is more than 5 months throughout the year, and it has overcome the extremely cold weather with temperatures of only -20°C to -30°C for 2 months; in Foshan Industrial Park, fcv80 assumes commuting duties and provides services to the park. Provide green travel services and demonstrate environmentally friendly green transportation; fcv80 has also launched official operations on public roads in Wuxi, with high-load operation of 330,000 kilometers per year, which is a test of vehicle performance; in Dalian and Changzhi, fcv80 will serve as a commuter shuttle to provide local green services Travel services. The results of this dedicated effort are reflected in market performance. According to recent statistics on the domestic hydrogen fuel cell bus market based on compulsory traffic insurance data, the cumulative sales of SAIC Maxus FCV80 from January to July this year reached 305 units, ranking first in the industry, with a market share of 53.42%. The eye-catching thing about this number is not only that it ranks first in the industry, but it is also greater than the combined sales of the second to eighth types. Because of their full dedication, when SAIC Maxus’s hydrogen fuel vehicle sales exceed the sum of other companies, people can always sigh in their hearts: the market will reward those companies that really do things down-to-earth. In the field of fuel cells, with the participation of “doers”, the future will no longer be foggy.Column editor: Li Ji Author of this article: Shen Xinhua Text editor: Liao Shiqi
