As part of the move toward series production, prototypes of the BMW iX5 Hydrogen are currently undergoing a testing program. The primary focus is on validating the entire system under various environmental and operating conditions.

The development teams ensure that all components function properly within the vehicle system and optimize the complex control of the systems, even under heavy loads. The goal is to ensure the full performance of the powertrain at all times while further optimizing the driving dynamics of the fuel cell vehicle.

The current testing is intended to demonstrate that the fuel cell system, electric motor, high-voltage battery, hydrogen storage tank, and Energy Master work together seamlessly. The high-voltage battery and the Energy Master—which serves as the central control unit for the high-voltage system—enable higher regenerative braking performance and, according to the manufacturer, thereby increase the efficiency of the overall system. At the same time, the development aims for performance on par with the iX5, including a target acceleration time of under five seconds from 0 to 100 km/h (0 to 62 mph).

Fuel Cell System Enters Next Phase of Construction

In addition, BMW is launching the next prototype development phase for the new fuel cell system at its Hydrogen Competence Center in Munich. The focus is on finalizing and validating the testing methodology, as well as continuing preparations for industrialization. The previous prototype phase concentrated on the manufacturability of the components and the basic capabilities of the suppliers. The upcoming process steps will lay the groundwork for efficient manufacturing processes and thus make an important contribution to future series production. Series production of the fuel cell systems will take place at the Steyr plant in the future.

Test Benches at the Steyr Plant

With the start of the new construction phase, the project is taking another step forward on the path to industrialization. To this end, the first test benches and production facilities have already been set up in Steyr, and employees have been trained. The insights gained from this process form the basis for the next steps in industrialization and the subsequent ramp-up of production.

To ensure that hydrogen, in addition to electric powertrains for trucks, becomes more widely adopted as an alternative propulsion option, several major companies are now collaborating. Here’s who they are and what exactly this is all about ... (Image:AI-generated)
