Recently, Song Dongxian, Vice President of Technology of Great Wall Motors, said when talking about hydrogen energy that this is a very important energy supplement in the future. The advantage of hydrogen lies in storage, while the storage of electricity is a relatively big problem. , hydrogen will play a pivotal role in the future energy society.
Song Dongxian revealed that Great Wall Motors’ first-generation hydrogen fuel cell prototype will be launched in 2021, with a range of about 900 kilometers and an acceleration of about 9 seconds. The second-generation fuel cell system will be released in 2023, with a range of 1,100 kilometers and an acceleration time of 5 seconds.
In addition, according to previous plans, Great Wall Motors will display a fleet of fuel cell passenger cars during the 2022 Beijing-Zhangjiakou Winter Olympics, and will launch a relatively mature mass-produced hydrogen fuel cell passenger car in 2023. .
Faced with more intense competition in the auto market in the future, Song Dongxian said that in the future, Great Wall Motors will refine and create a unique technological ecosystem unique to the company, compete from an ecological perspective, and build leadership strength.
Great Wall Motors, one of the representatives of independent brand car companies, has been continuously increasing its deployment in the field of hydrogen energy in recent years.
As early as 2016, Great Wall Motors began to formally deploy hydrogen energy. Great Wall Holding Group established the "XEV" project to start FCEV research and development. It was led by an authoritative expert team in the international hydrogen energy industry and officially entered hydrogen energy and hydrogen fuel. Battery core components field.
In 2017, Great Wall Motors also officially joined the International Hydrogen Fuel Cell Association.
In February 2018, it joined the China Hydrogen Energy and Fuel Cell Industry Innovation Strategic Alliance.
In March 2018, it joined the International Hydrogen Council (Hydrogen Council) and is currently the only Chinese car company to join the committee.
In June 2018, Great Wall Motors established a hydrogen technology center in Baoding. This is the first hydrogen technology center in China with a full set of testing and trial production equipment, and the first 105MPa high-pressure hydrogen cycle test bed in China. , the first domestic 6-axis hydrogen storage bottle winding machine, the first domestic fuel cell power system test bench and the first domestic liquid hydrogen storage and refueling station, etc.
In August 2018, Great Wall Motors acquired 51% stake in Shanghai Fuel Cell Vehicle Power System Co., Ltd. (hereinafter referred to as Shangsha Power) (100% of Shangsha Power was held in April 2019).
In 2019, Great Wall Motors invested 450 million yuan to establish Weishi Energy Technology Co., Ltd., which is positioned as a high-tech enterprise focusing on the market-oriented operation of hydrogen fuel cell technology. It is mainly engaged in the research and development of hydrogen fuel cell products. Production and sales. At the Shanghai Auto Show in the same year, Weishi Energy exhibited products such as an 85KW fuel cell system and IV-type hydrogen storage bottles.
It is understood that Great Wall Motors has been conducting research and development of hydrogen fuel cells for more than four years. At present, the entire R&D team has more than 300 people, including people from Germany, the United Kingdom, Canada, the United States, Japan, South Korea, India, etc. There are more than 50 foreign experts from China. In addition to the domestic R&D center, a R&D center has also been established in Munich, Germany.
It is worth mentioning that in June this year, the first 70MPa automotive high-pressure bottle valve independently developed by Weishi Energy Technology Co., Ltd. entered the final testing stage before mass production, and the production and manufacturing work has also initially started. , and plans to officially launch it on a large scale in the second half of 2020.
It is reported that this 70MPa automotive high-pressure bottle valve combines high safety, high integration, high cost performance, high stability, lightweight, miniaturization, low power consumption, long life, and low cost. and other technical advantages, the total number of parts is 49, which is more than 20 fewer than the current mainstream products in the market. At the same time, through the redundant design of electromagnetic force and valve body strength, the product cycle filling life is ≥15,000 times, and the solenoid valve opens and closes. The service life is ≥75,000 times. The overall weight of the bottle valve is only 500g. It has completely independent intellectual property rights and has applied for more than ten national patents.
