After several years of preparation BMW i Hydrogen NEXT, BMW will eventually begin testing a close-to-standard FCEV fleet under daily conditions on European roads.
The Bavarian car manufacturer will study how carbon dioxide-free drivetrains, specific vehicle chassis technology and vehicle electronic systems work together effectively under real-world conditions.As you know, the prototype car is based on G05 X5, BMW plans to release it as a small series at the end of 2022.
For those unfamiliar with fuel cell electric vehicles, it is essentially an all-electric vehicle that is powered by mixing hydrogen and oxygen.In i Hydrogen NEXT, this chemical reaction Generates 125 kW (170 PS) of powerAfter a series of voltage adjustments, all of these are sent to the motor.
Unused energy is stored in high-performance buffer batteries (smaller and lighter than pure electric vehicles), providing short-term explosive power for overtaking. At this stage, the total output power of the system is 275 kW, or 374 PS. Batteries are not the main energy source required for propulsion. Hydrogen is.
Like the fuel tanks of ordinary models, the hydrogen tank of BMW i Hydrogen NEXT can be filled up within three to four minutes. Regardless of the weather, a single pump can almost guarantee a cruising range of hundreds of kilometers.
But unlike the fuel tanks of ordinary cars, fuel cell cars store hydrogen in high-pressure tanks. In the case of i Hydrogen NEXT, it has two 700 bar tanks made of lightweight carbon fiber reinforced plastic, capable of storing 6 kg of hydrogen. Water vapor is the only emission produced by this transmission system.
BMW said that hydrogen fuel cell technology has the long-term potential to complement internal combustion engines, plug-in hybrid power systems and pure electric vehicles (BEV). For customers who do not have access to the charging network or who often drive long distances, it may be an attractive alternative to BEV.Jaguar Land Rover Also echoed this sentiment.
“Hydrogen fuel cell technology can be an attractive option for sustainable powertrains-especially in the larger vehicle category,” said Frank Weber, a member of the BMW board responsible for development. “This is why the use of hydrogen fuel cell drive systems to conduct road tests on vehicles that are close to standards is an important milestone in our research and development work.”
Extensive road testing will help development engineers verify the efficiency, safety, convenience and reliability of all components. BMW also needs to fine-tune the driving characteristics of the car, because no matter what the power source is, BMW should drive like a BMW.If you forget, the fuel cell system in i Hydrogen NEXT is BMW and Toyota’s long-term partnership.
