All of the elements that enable this technological leap forward come together in the BMW Energy Master. This central control unit is positioned on the high-voltage battery and provides the interface for high- and low-voltage power supply and for data from the high-voltage battery. It also controls the power supply for the electric motor and vehicle electrical system and ensures the safe and intelligent operation of the high-voltage battery. The BMW Group has filed a whole series of new patent applications for the vehicle electrical system, including its electronic fuses. Both the hardware and software of the Energy Master were developed fully in-house at the BMW Group. This ensures technological developments and updates for vehicles can be implemented independently and in real time via Remote Software Upgrades, providing a particular benefit for customers.
the brain of the high-voltage battery - the energy master.
From Landshut into the world: the BMW Group plant Landshut is the only production site for Energy Masters worldwide. A state-of-the-art production system for the BMW Energy Master is taking shape at Plant Landshut. The plant is currently producing the highly complex control unit in pre-series. Series production on the first production line will begin in August 2025, with a further expansion stage to follow in mid-2026. This is the first time the development and production of this central control unit has taken place in-house at the BMW Group. Around 200 people will be employed in the Energy Master production area at Landshut when production begins, rising to as many as 700 people as it ramps up further. The BMW Group has channelled investment in the high hundreds of millions of euros into the expansion of electric mobility at Plant Landshut since 2020, strengthening both the production facility itself and Germany’s status as an industrial powerhouse for the long term. The modular manufacturing system used to produce the Energy Master was also designed fully in-house by the BMW Group. It is supplied with subcomponents by a supply chain set up by the BMW Group. This extends to the n-tier supply chain for supply-critical components such as semiconductors. The benefits of this set-up can be seen in terms of both costs and supply security. The scalable production system enables the company to respond quickly and flexibly to market requirements. The high degree of automation, involving up to 400 robots in the final expansion stage, maximises efficiency. Comprehensive in-process monitoring, which includes the use of AI-based camera systems, and 100-per-cent end-of-line system checks in a clean-room environment ensure optimum quality.
