On September 13, a super conference with the theme "Extreme Technology•Reliable Power" was held online. Weishi Energy, a subsidiary of Great Wall Holding Group, has released a 95kW passenger car fuel cell system engine, a platform fuel cell stack that can be expanded to a maximum of 150kW, and a 70MPa high-pressure hydrogen storage cylinder valve and reducer. Core products such as pressure valves. The press conference officially announced that Weishi Energy Hydrogen’s “joint fleet” will go out and the Great Wall Hydrogen’s strategic layout will be further advanced.

"Extreme Technology•Reliable Power" Super Conference

363 patents, 1,045 rigorously tested the potential for energy to break through the core key technology of hydrogen energy. Since the beginning of 2016, Great Wall Holdings Group has listed the development of hydrogen fuel cells as a key project of the group, aiming at the world’s frontier key technology fields of hydrogen fuel cells, for passenger cars, The commercial vehicle market has carried out platform-based component design. Up to now, it has invested a total of 1.57 billion yuan in its own funds for product development. Weishi Energy, a subsidiary of Great Wall Holdings, focuses on the R&D, manufacturing and sales of hydrogen energy technology. It has a professional R&D team, a hydrogen energy test base, a fuel cell trial production center, a hydrogen production and liquefaction plant, and a supporting vehicle test field, environmental storage and other high-quality Resources. After five years of exploration, Weishi Energy successfully applied for 363 core key technology patents in the field of hydrogen energy and fuel cells. In the research and development process, while strictly following the product development V process, all products have undergone 1045 rigorous tests to create products with super reliability from the source of design and development. Zhang Jinhua, secretary-general of the Chinese Society of Automotive Engineering, stated at the press conference that Weishi Energy invested heavily in the development of hydrogen energy and fuel cell vehicle business, and mastered core key technologies, which is the embodiment of Great Wall’s focus and professionalism, and hopes Weishi Energy will become a national brand in the industry. Flag, make persistent efforts and lead the industry's technological innovation. Wu Zhixin, deputy general manager of the China Automotive Technology Research Center, praised: “Weishe has put forward the wisdom of its own brand by throwing out solutions to problems, and has provided excellent cases for industry enterprises.”

Core technical parameters of 95kW passenger car fuel cell system engine

The 95kW fuel cell engine launched by Weishi Energy has undergone component testing, module testing, system testing, powertrain testing, and vehicle testing. There are thousands of rigorous tests on 5 levels, and it is equipped with a "proportional solenoid valve". +Single ejector" hydrogen circulation module, compared with the hydrogen circulation module using a hydrogen circulation pump, save 100% of the cost.

Platform fuel cell stack that can be expanded up to 150kW

The 150kW platform fuel cell stack has achieved a comprehensive breakthrough in the high power of the fuel cell stack and the uniformity of the single cell voltage of the stack. With the help of the five “killers” of bipolar plate design, membrane electrode development, overall uniformity simulation of the stack, stacking process control, and single cell drainage performance; and the “NODS system” developed by Weishi Energy, remote online diagnosis and upgrade system, Through real-time monitoring of the fuel cell's operating status, remote fault diagnosis and cloud upgrades are realized, and corresponding control strategies are continuously adjusted, the life of the fuel cell stack is effectively extended by more than 20%.

70MPa high pressure bottle valve

The 70MPa high-pressure hydrogen storage cylinder valve and the two-stage pressure reducing valve have completed the mainstream design of high-pressure hydrogen storage valve with high integration, light weight and low power consumption. The complete set of hydrogen storage coordination is achieved only by the hydrogenation port-bottle valve-hydrogen bottle- The process layout of the pressure reducing valve group-combustion power system reduces the hidden danger of leakage from the root cause. The total number of bottle valve parts is reduced by more than 20% compared to mainstream products in the current market. The pressure reducing valve group integrates a one-way valve, a bipolar filter unit, and a high-pressure shunt unit. The overall weight of the two valves is equivalent to 1/3 of the current market mainstream products. In terms of safety and tightness, the leakage rate of hydrogen leakage test is far less than domestic and foreign standards. Great Wall Motor’s first fuel cell SUV will be mass-produced in 2021. Among the three fuel cell core components released by Weishi Energy, the 95kW passenger car fuel cell system engine has been successfully equipped with Great Wall Motor’s first fuel cell to be launched. SUV, which will be mass-produced in 2021. At the same time, based on its position as an automotive hydrogen energy expert, Weishi Energy adopts a two-legged strategy of "commercial and multiplier". Shangran Power, a subsidiary of Weishi Energy, is positioned as an important strategic support point for the research and development of domestic commercial vehicle fuel cell systems. Together with Dayun Motors, it launched a fuel cell heavy-duty truck model equipped with a self-developed 100kW commercial fuel cell engine --- surpassing 300E and breaking the service life 10,000 hours, the whole vehicle's one-time cruising range can reach 1,100 kilometers.

Vehicle-level working condition test station

Both the 70MPa hydrogen storage cylinder valve and the pressure reducing valve have reached mass production, and the 70MPa IV hydrogen storage cylinder will be officially launched in 2021.

Weishi Energy's 1000 independent high-power stack production line

The 150kW high-power independent stack production line with an annual capacity of 1,000 sets was put into service in July of this year, and the product will be officially launched on the market in 2021.
