A few days ago, Mr. zipze, chairman of BMW Group, and Mr. Wei Bofan, director in charge of R & D, announced the start of small-scale mass production of hydrogen fuel cells at the BMW hydrogen technology center in Munich. BMW ix5 hydrogen fuel cell vehicle will be put into use at the end of this year for vehicle testing and vehicle display worldwide. With the excellent combination of high-performance fuel cells and high-power power power batteries, BMW has added a new choice for sustainable travel to the luxury car segment, further enriching BMW's new energy product portfolio.

Extension · official introduction

Mr. zipce, chairman of BMW Group, said: "Hydrogen energy, as a versatile energy source, plays an important role in carbon neutralization. As one of the ways to travel in the future, hydrogen powered vehicles are also becoming more and more important. In addition to electric vehicles, we believe that hydrogen powered vehicles have ideal technical advantages and can further enrich BMW's new energy product portfolio. Through the current small-scale mass production of hydrogen fuel cells, BMW has fully demonstrated this drive line The technical maturity of the system and its potential in future travel. "

Mr. Wei Bofan, director in charge of R & D of BMW Group, said: "after years of R & D, we have been able to maximize the use of hydrogen energy technology. In the second generation fuel cell of BMW ix5 hydrogen fuel cell vehicle, we have successfully doubled the continuous output power of the fuel cell, while significantly reducing its weight and size."

New car information

1. Combination of high-performance fuel cell and high-power power power cell

BMW ix5 hydrogen fuel cell vehicle integrates hydrogen fuel cell technology and the fifth generation BMW Edrive electric drive technology. The unique drive system consists of two hydrogen storage tanks, a fuel cell and a motor. The total output power of BMW ix5 hydrogen fuel cell vehicle can reach 275kw (374hp). Among them, the high-performance fuel cell can continuously output 125 kW (170 horsepower) of electrical energy. The combination of high-performance fuel cells and high-power power power cells has brought outstanding performance to BMW ix5 hydrogen fuel cell vehicles, which can not only realize the pure tram type zero emission travel, but also have the same feeling as fuel vehicles. Long distance driving can be filled with fuel only after a short stay, and is not affected by seasonal changes and outdoor temperature.

At the beginning of this year, the BMW ix5 hydrogen fuel cell vehicle has shown extraordinary sports performance and comfortable driving experience in the last round of winter tests in aljeplug, Sweden. Under ultra-low temperature climate conditions, BMW ix5 hydrogen fuel cell vehicle can travel to a maximum range of about 500 kilometers. It only takes 3-4 minutes for the hydrogen storage tank to be full, and its use experience is no less than that of traditional internal combustion engine models.

The excellent test results of the new small-scale mass-produced models are inseparable from the rich experience of BMW Group in hydrogen fuel cell drive technology. Before the advent of the hydrogen fuel cell system, internal combustion engines powered by hydrogen have been applied. As early as 2006, the BMW Hydrogen 7 series concept car appeared in Berlin, marking the birth of the world's first hydrogen powered luxury high-performance car and a milestone of the BMW Group's commitment to sustainable development in the future.

Based on the consideration of efficiency, since 2015, the R & D Department of BMW Group has continuously carried out development work in this field, and launched the BMW 5 Series GT hydrogen fuel cell vehicle based on hydrogen fuel cell technology. Since then, with a large amount of proprietary technology in the field of traditional drive technology and strict standards for all models, BMW's fuel cell technology has been increasingly refined.

2. BMW hydrogen fuel cell system starts production in Munich

BMW Group continues to actively promote hydrogen powered green and sustainable travel in the future. Since 2013, BMW Group and Toyota Motor Company have continuously deepened cooperation. According to the cooperation agreement, both parties will be committed to promoting the research and development of hydrogen fuel cell technology and industrial scale application. BMW group purchases fuel cell units required for manufacturing BMW ix5 hydrogen fuel cell vehicles from Toyota Motor Company.

Traditional internal combustion engines are equipped with technical functions such as air humidifier, air filter, control unit and sensor. On this basis, BMW Group has specially developed hydrogen components for the new hydrogen fuel cell system, such as air compressors and high-pressure cooling pumps.

The manufacturing of a fuel cell system includes two steps. First, the fuel cells are assembled into a fuel cell stack. Fuel cell stack is the place where electrochemical reactions take place and the core part of fuel cell system. Subsequently, the fuel cell stack will be compressed by the machine at a pressure of 5 tons, and the stack shell will be installed for it.

The hydrogen fuel cell drive system explains BMW's accumulation and foresight in the field of electric travel, and will become a new member of the new energy product portfolio of BMW Group to further realize the diversified transformation to zero emission travel. In the future, BMW I brand, which focuses on zero emission travel, will not only provide pure electric vehicles, but also bring hydrogen fuel cell models to meet more diverse customer needs; For example, it is far from charging infrastructure, needs long-distance travel, and pursues personalization.
