The BMW iX5 Hydrogen is currently undergoing a demanding test program under particularly challenging weather conditions. The vehicle is thus undergoing its final winter testing on public roads and at the BMW Group's test center in Arjeplog in northern Sweden. The integrated functional testing and validation of the fuel cell system, the hydrogen tanks, the power buffer battery and the central vehicle control unit makes it clear that this additional option for CO2-free mobility can reliably ensure sustainable driving pleasure with a high level of comfort and unrestricted performance, even in extreme minus temperatures.
BMW iX5 Hydrogen
With the road tests in the Arctic Circle, the BMW Group is continuing the development process for the BMW iX5 Hydrogen and will produce a small series of this model later this year. At the same time, the company is committed to expanding the network of hydrogen filling stations. “Winter testing under extreme conditions clearly shows that the BMW iX5 Hydrogen offers full performance even at temperatures of minus 20 degrees and is therefore a valid alternative to the BEV. In order to be able to make our customers an attractive offer for sustainable mobility with a fuel cell, an adequate hydrogen infrastructure is also required,” says Frank Weber, Member of the Board of Management of BMW AG for Development.
BMW iX5 Hydrogen: typical BMW driving dynamics, range and suitability for everyday use in every season.
During the test drives on ice and snow in the region around Arjeplog, the BMW iX5 Hydrogen shows how reliable, comfortable and powerful the hydrogen fuel cell drive can already cover the mobility requirements in everyday use. There, after hundreds of test runs on test benches and intensive practical testing on the road, it is now completing a further development step.
This shows that the hydrogen fuel cell drive has the same suitability for everyday use as a conventional combustion engine, especially at very low temperatures. The full system performance is available shortly after the start. The range of the drive system remains unrestricted in the freezing cold. In addition, filling up the hydrogen tanks only takes three to four minutes, even in the depths of winter. "Regardless of the time of year and outside temperatures, the hydrogen fuel cell drive combines the best of both drive worlds: the locally emission-free mobility of an electric vehicle and the unrestricted suitability for everyday use, including short refueling stops, as is known from models with combustion engines," says Jürgen Guldner, Head of BMW Group Hydrogen Fuel Cell Technology and Vehicle Projects.
The drive system of the BMW iX5 Hydrogen combines fuel cell technology with a Electric motor from the fifth generation of BMW eDrive technology. Hydrogen, which is stored in two 700 bar tanks made of carbon fiber reinforced plastic (CFRP), serves as the energy source. The fuel cell converts the hydrogen into electricity and generates an output of 125 kW/170 hp. In addition, the electric motor can use the energy stored in a power battery. This is charged either by recuperation or the fuel cell. As a result, one stands for particularly dynamic driving situations System output of 275 kW/374 hp to disposal. The fuel cell releases water vapor as the only emission. Your waste heat is used in a particularly efficient way to heat up the interior.
unique drive system for every need
All drive, energy storage and control systems pass their ultimate endurance test in the winter landscape of Lapland. In addition, specially prepared ice surfaces and snow-covered roads offer ideal conditions for the integrated application of all drive and chassis systems. This also applies to the steering, suspension and damping, the chassis control systems and the interaction between the friction brake and the deceleration by means of recuperation. Here, too, the BMW iX5 Hydrogen can demonstrate its advantages, since the vehicle weight is lower than that of a comparable battery-electric model.
With the combination of fuel cell and power buffer battery, the BMW iX5 Hydrogen has a worldwide unique drive system. Its technology has the potential to become another pillar in the BMW Group's drive portfolio for local CO2- to form free mobility. The BMW i brand, which is completely geared towards locally emission-free mobility, could in future also offer vehicles with hydrogen fuel cell drives in addition to battery-electric models. In this way, the mobility requirements of customers who do not have their own access to an electric charging infrastructure, who often travel long distances or who want a high level of flexibility can be met.
BMW Group supports the creation of a nationwide hydrogen infrastructure.
An important prerequisite for sustainable individual mobility in the form of fuel cell vehicles, in addition to the generation of hydrogen using regenerative energy, is a comprehensive supply infrastructure. “As the BMW Group, we therefore support the efforts of the EU Commission to implement the AFIR (Alternative Fuels Infrastructure Regulation) to the parallel Development of hydrogen filling stations and an electrical charging infrastructure", says Juergen Guldner. "We would like to see an even more ambitious design and earlier implementation." As part of the Green Deal legislative package "Fit for 55", the European Commission is striving to create a binding basic infrastructure. With the implementation of the AFIR draft, 700-bar hydrogen filling stations are to be set up in all member states of Europe at a maximum distance of 150 kilometers from each other along the main roads. The BMW Group welcomes this initiative and calls for the distances to be reduced to 2027 kilometers by 100.
The BMW Group also welcomes and supports current activities to promote innovations in Germany and Europe that serve to build up a hydrogen economy and promote the production of green hydrogen. These include in particular those in the IPCEI (Important Projects of Common European Interest) combined large-scale hydrogen projects. The European Union initiative, which is funded in Germany by the Federal Ministry of Economics and Transport and the federal states, covers the entire value chain with its projects - from hydrogen production and transport to various applications in the areas of building heating, energy supply, industry and mobility. The BMW Group already expressed its interest in participating in this initiative in 2021. As part of IPCEI, the company could significantly advance the development of fuel cell and tank systems and thus take an important step on the way to the industrialization of hydrogen technology for individual mobility.
