BMW begins everyday testing of hydrogen fuel cell drive train

BMW i NEXT

BMW Group is beginning to test near-standard vehicles with a hydrogen fuel cell drive train in everyday conditions on European roads.

Prototypes of the BMW i Hydrogen NEXT, a pure electric vehicle that uses hydrogen as fuel by converting it into electricity in a fuel cell, will examine how effectively the CO2-free drive train, model-specific chassis technology and vehicle electronics systems work together under real-life conditions.

The recently launched testing programme will pave the way for the BMW Group to present a small-series model with this sustainable drive technology, developed on the basis of the BMW X5, in late 2022. Extensive field testing of these vehicles will provide practical experience in the use of this sustainable drive technology.

Frank Weber, member of the Board of Management of BMW AG responsible for Development, commented: “Hydrogen fuel cell technology can be an attractive option for sustainable drive trains – especially in larger vehicle classes. That is why road testing of near-standard vehicles with a hydrogen fuel cell drive train is an important milestone in our research and development efforts.”

Like the fuel tank of a conventional combustion-engine model, the hydrogen tank of the BMW i Hydrogen NEXT can also be filled within three to four minutes with a fuel that ensures a range of several hundred kilometres in all weather conditions.

A central element of the BMW i Hydrogen NEXT road tests now underway is fine-tuning the software that controls all driving and operating functions. The fuel cell system, hydrogen tanks, performance buffer battery and central vehicle control unit have all previously been tested individually and together in hundreds of test runs conducted on test benches.

This functional testing is now being followed with field testing on the roads. The intensive programme, which is conducted under everyday conditions, with thousands of kilometres driven in real traffic situations, helps development engineers validate the efficiency, safety, convenience and reliability of all components.

The BMW i Hydrogen NEXT uses fuel cells from the product development cooperation with the Toyota Motor Corporation. The individual cells come from Toyota, while the fuel cell stack and complete drive system are original BMW Group developments. The cooperation established in 2013 seeks to optimise the everyday practicality and scalability of hydrogen fuel cell technology for use in each company’s respective production vehicles through the intensive exchange of experience.
