We learned from official sources that the BMW iX5 Hydrogen fuel cell vehicle has entered the late research and development stage before mass production, and the small-scale mass production model will be officially put into production in the second half of this year. The vehicle is currently undergoing a rigorous extreme cold endurance test at the BMW Group Winter Test Center in Arjeplug, Sweden.
In extremely cold environments, the BMW iX5 Hydrogen fuel cell vehicle is capable of driving up to a maximum range of approximately 500 km. The hydrogen storage tank takes only 3-4 minutes to fill, and it is not affected in the cold winter.
Julgen Guldner, Head of the HYDROGEN Fuel Cell Technology and Automotive Project at the BMW Group, said: "Hydrogen fuel cell drive systems combine the advantages of both drive systems and are not affected by seasonal variations and outdoor temperatures. It can not only achieve zero-emission travel of pure electric models, but also feel the same as fuel vehicles in terms of use, and long-distance driving only needs a short stay to be full of fuel. ”
It is understood that the drive system equipped with the BMW iX5 Hydrogen fuel cell vehicle integrates hydrogen fuel cell technology and the fifth generation BMW eDrive electric drive technology, and the maximum total power of the system can reach 275 kilowatts. In addition, the hydrogen required to supply the fuel cell is stored in two 700 bar pressure tanks made of carbon fiber reinforced composite materials, which chemically react with oxygen to provide 125 kilowatts of electrical energy to the rear axle-mounted electric motor.
The high-power battery located above the motor can not only be charged by the fuel cell, but also use the electricity generated by the braking energy recovery system. When overtaking or accelerating, the battery injects extra power into the vehicle. The vehicle does not emit any exhaust gases except water vapor, and the excess heat generated can be efficiently recovered for heating the cockpit.
