BMW Group strengthens battery expertise as part of the European Battery Innovation initiative.

 

The BMW Group is accelerating its development for the battery technology of the future, thereby supporting the ramp-up of a European cell and battery value chain. 

In this context, Oliver Zipse, Chairman of the Board of Management of BMW AG, received a grant decision from the Federal Minister of Economics and Energy, Peter Altmaier, as well as from the Bavarian Minister of State for Economic Affairs, Regional Development and Energy, Hubert Aiwanger, in support of the BMW Group's battery projects within the framework of the battery IPCEI (Important Project of Common European Interest).

For the BMW Group, it is clear that high-performance and sustainable energy storage systems are the key success factor for the individual mobility of the future. The development of highly innovative and sustainable battery cells is therefore one key element of a high-performance European cell and battery value chain. This aspiration is reflected in the Neue Klasse, which the BMW Group first presented at its annual conference in March. This new generation of vehicles, which will be launched by the middle of this decade, will be uncompromisingly electric, digital, circular – and clearly focused on all-electric drivetrains.

For the Neue Klasse, the BMW Group is developing the next generation of its battery technology – combined with a clear aspiration: "With the Neue Klasse, we will make a big leap in technology in electric drive," said Oliver Zipse, Chairman of the Board of Management of BMW AG, in Munich on Monday. "We want to significantly increase the energy density of the cells and reduce the costs of material use and production at the same time. We will also significantly reduce the use of primary material to ensure a truly 'green' battery."

 With the Neue Klasse, the BMW Group aims at the level of state-of-the-art internal combustion engines in terms of range and manufacturing costs. For example, electric mobility "engineered by BMW" is intended to appeal to and convince new groups of buyers worldwide. For this sixth generation of BMW e-drive technology, the company evaluates correspondingly different cell formats, cell chemistry and also cell modules in the current development phase. A key goal is to create truly green, low-carbon and recyclable batteries.

Solid-state battery for serial use – demonstrator vehicle well before 2025. However, the BMW Group is already planning further into the future beyond this next generation: By the end of the decade, the energy density of battery cells is expected to increase by at least a mid-double-digit percentage range – from an already high level today.

Frank Weber, Member of the Board of Management of BMW AG, Development: "The greenest electric car in the world will be a BMW – sustainable from the initial idea to recycling after its use phase. We are developing the battery cell of the future: it will be powerful, safe, cost-effective, and recyclable - from material selection to recyclability after the use in the vehicle. All of this will be created in a European value chain." Weber continues: "We are doing intensive research on solid-state battery technology. By the end of the decade, we will be implementing an automotive-compatible solid-state battery for series production. We plan to show a first demonstrator vehicle featuring this technology well before 2025."

The BMW Group has had extensive in-house expertise in the complete value chain of electric drive for years and has optimized its battery cell technology from generation to generation. Cell chemistry has also been consistently further developed: for example, the proportion of cobalt in cathode material in the transition from Gen3 from the BMW i3 to Gen5, which was introduced in 2020 with the BMW iX3, was significantly reduced from 33 percent to 10 percent – at the same time, the nickel content rose to around 80 percent. In order to minimize the consumption of primary resources, up to 50 percent recycled nickel is already used in the high-voltage battery pack of the new BMW iX.

Thanks to intelligent vehicle architectures and a highly flexible production network, the BMW Group will have around a dozen all-electric models on the road as early as 2023. In addition to the BMW i3, MINI Cooper SE and BMW iX3, which are already on the market, two key innovation drivers, the BMW i4 and the BMW iX will be put on the road this year– the BMW i4 even three months earlier than originally planned. In the coming years, all-electric versions of the high-volume BMW 5 Series and the BMW X1 will follow. In addition, there will be an all-electric BMW 7 Series as well as the successor to the MINI Countryman and other models. As early as 2023, the BMW Group will have at least one all-electric model on the road in around 90 percent of its current market segments.

Based on current market expectations, the BMW Group is planning that by 2030 at least 50 percent of its global sales will consist of all-electric vehicles. In total, the company will bring about ten million all-electric vehicles onto the road over the approximately next ten years. This also means that the BMW Group is strategically on target of achieving the EU's ambitious CO2 reduction targets in 2025 and 2030.

The BMW Group is more involved in the research, development and industrialization of battery value chains in Germany than any other vehicle manufacturer. The research results achieved by the BMW Group and the partners involved in the IPCEI project strengthen the development of an integrated European battery value chain. In addition, various concepts for solid-state batteries are being researched together with European R&D partners and the most promising prototype is being implemented. In doing so, the company is paving the way for successful battery cell development and production in Europe.
