BMW Group is building on its leading position in the world of electric mobility and has pooled its many years of experience with battery cells and extensive knowledge in the field in a new Competence Centre. The purpose of the facility in Munich is to advance battery cell technology and carefully dissect the production processes

The BMW Group today presented its new high-tech Competence Centre to media representatives from around the world in the presence of Bavarian state premier Dr Markus Söder, revealing state-of-the-art labs, research facilities and prototype systems.

The BMW Group is developing future generations of battery cells at the new Competence Centre, focusing on customer-relevant aspects, such as improving energy density, available peak output, service life, safety, charging characteristics and performance at varying temperatures, and reducing battery costs. The BMW Group’s aim of developing the best battery cells for its models was formulated with these specifications at the forefront, reflecting the company’s commitment to giving electrified vehicle owners the very best cells for the vehicle concept at hand.

Selecting the right materials from the beginning is crucial if these high standards are to be met. For this reason, the experts at the Competence Centre are constantly investigating innovative materials and systematically comparing them with one another. This leads to the creation of new material sets for the battery cell’s individual elements: the anode, cathode, electrolyte and separator. The way in which the various materials interact – the cell chemistry, in other words – is another fundamental factor in the evolution of the cell design.

To guarantee access to the latest developments and knowledge at all times, the BMW Group works together with renowned worldwide partners throughout the value chain. These partners range from scientific institutions and universities to established companies and start-ups. And that enables the company to acquire know-how, ensures it is not dependent on individual developments and means it can create synergies and ultimately shorten development times. Working with a network of partners allows the BMW Group to consolidate its in-depth understanding of this cutting-edge technology and exploit the potential and opportunities of future innovations.
