Recently, the group announced the technical details of BMW I hydrogen next hydrogen power system for the first time, and reiterated that the company is systematically and comprehensively promoting the landing of zero emission travel. The maximum power of the system is 125KW (170ps), and the time for refueling is only 3-4 minutes. "BMW I hydrogen next hydrogen power system" and "battery device" the system used by BMW I hydrogen next power system generates chemical reaction between hydrogen and oxygen in the air. Except for water vapor, the vehicle does not emit any exhaust gas, and the maximum power is 125KW (170ps). A DC converter is installed under the fuel cell of the system to match the voltage level of the fuel cell with that of the electric power system and high-power type. High power batteries can not only be charged by fuel cells, but also can use the power generated by braking energy recovery system. The fifth generation Edrive electric drive system vehicle is also equipped with a pair of 700bar (70MPa) hydrogen storage tanks, which can hold a total of 6kg of hydrogen, and the hydrogenation process only takes 3-4 minutes. The fifth generation Edrive electric drive system, which will be used for the first time on the BMW ix3, will also be integrated into the BMW I hydrogen next, with a total power of 275kw (374ps). "BMW I hydrogen next hydrogen fuel cell concept car" in addition, BMW I hydrogen next will be equipped with fuel cells developed by BMW Group in cooperation with automobile companies and fuel cell sets and overall drive systems independently developed by BMW Group. According to the cooperation agreement, both parties will be committed to the research and development of hydrogen fuel cell technology, including fuel cell power system and expandable modular components. Since 2013, BMW Group and Toyota Motor Company have been deepening cooperation to promote the research, development and industrialization of hydrogen fuel cell technology. In addition, the two sides are founding members of the international Hydrogen Energy Commission. "We firmly believe that in the future, multiple power systems will coexist for a long time, because at present, there is not a driving form that can meet all the travel needs of customers around the world," said Fu Lechi, director of research and development of BMW Group. In the long run, hydrogen fuel cell technology is likely to become the fourth pillar of BMW's powertrain portfolio. This technology is particularly suitable for the popular BMW x family of large-scale models. " According to previous reports, BMW Group is expected to launch 25 electric models by 2023, at least 12 of which are models.
