“With the
new battery system production facility in Luhe-Wildenau, we are making a clear
commitment to Germany as a production and innovation hub. We are investing
specifically in key technologies, creating high-quality jobs in the region, and
strengthening the competitiveness of the domestic rail industry. At the same
time, we are making an important contribution to the mobility transition and
sending a strong signal for the future viability of Germany as a business
location,” said Karl Blaim, CFO of Siemens Mobility.
“This
project will drive Bavaria forward, both technologically and economically. The
production of state-of-the-art train batteries is a key, future-oriented field
that will benefit not only Luhe-Wildenau and the Upper Palatinate, but Bavaria
as a whole. Siemens Mobility is developing battery systems here that combine
strong acceleration performance with high energy capacity for long-distance
travel, so we can look forward to more powerful and efficient trains. At the
same time, many high-quality jobs will be created in the region. This project
will therefore strengthen our business location in the long term,” said Hubert
Aiwanger, Bavarian Minister of State for Economic Affairs.
Battery systems – key technology for decarbonization
Since
2017, Siemens Mobility has been the market leader in battery-electric regional
trains and is also planning to build battery-electric locomotives for freight
transport. The foundation for this is the key technology of the battery system,
which must meet significantly higher requirements for robustness and durability
than comparable solutions in the automotive sector. Typical storage capacities
are around 500 kilowatt-hours for regional trains and up to 2,000
kilowatt-hours for locomotives.
In Luhe-Wildenau, Siemens Mobility will in the future produce complete battery systems, including an innovative Battery Management System (BMS), developed together with Munich-based company Stercom. The BMS monitors and controls the battery, ensures safe operation, and maximizes efficiency and service life. The battery cells are sourced from external suppliers such as Toshiba, while system integration is carried out by Siemens Mobility.
Site advantage and investment in the future
Battery
system pre-assembly already takes place today in Luhe-Wildenau. Building on
this long-standing expertise, Siemens Mobility is now establishing full-scale
system production at the site. In the future, the plant will be able to produce
up to 120 megawatt-hours of battery capacity per year in three-shift operation.
Siemens Mobility is investing around €22
million in the development of a modular battery family and an innovative
battery management system (BMS). Another part of the investment is going into
production and automation technologies, including state-of-the-art welding
processes. The Free State of Bavaria is supporting the project with €2.7
million from state funding programs. The site was developed in cooperation with
regional project developer and construction company Dirnberger Real Estate GmbH
and DIMONDA Projektbau GmbH. These companies act as investors and landlords of
the site and are responsible for the management and realization of the project.
With the new battery system production
facility, Siemens Mobility is not only strengthening Luhe-Wildenau as a
future-proof industrial location but also sending a clear signal for the
competitiveness and innovative strength of Germany as a business hub.
