Siemens Germany Battery Factory: Rail Innovation & Sustainability

“`html

Introduction

Siemens Mobility has commenced construction of a new facility in Luhe-Wildenau, Bavaria, Germany, with a total investment of approximately €35 million ($41 million) to manufacture battery systems for rail vehicles.

Construction and Investment

Siemens Mobility is investing around €22 million in the new facility in Luhe-Wildenau. The Free State of Bavaria is contributing €2.7 million through state funding programs. The facility will occupy approximately 20,000 m².

Battery System Development

Siemens Mobility’s investment will support the development of a modular battery family and a new battery management system (BMS). The BMS is being built in collaboration with Stercom, a Munich-based company. Additional funds are directed toward production and automation technologies, including welding processes. The factory is scheduled to be completed in spring 2027, with series production planned to begin in October 2027. The facility is planned to employ up to 200 people.

Production and Capacity

The facility will produce battery systems for Siemens Mobility’s regional trains, locomotives, and external customers. Upon full operation, the factory aims to reach an annual output of up to 120MW of battery capacity with three-shift operations. Battery cells for the systems will be supplied by external companies such as Toshiba. Siemens Mobility will integrate these cells into the final systems. Pre-assembly of battery systems already occurs at the Luhe-Wildenau location.

Project Collaboration and Additional Projects

The development of the site involves cooperation with Dirnberger Real Estate and DIMONDA Projektbau, who are responsible for site management and project delivery. In August this year, Siemens Mobility secured a contract with the Regie Autonome des Transports Parisiens (RATP) to fully automate Paris Metro Line 13 using its advanced CBTC GoA4 technology.

Conclusion

The new Siemens Mobility facility in Luhe-Wildenau, Germany, represents a €35 million investment aimed at producing battery systems for rail vehicles. The factory is scheduled for completion in spring 2027 and will have a capacity of up to 120MW annually.
