ABB’s Supply of Traction Converters and Energy Storage Systems

ABB has secured a contract with Stadler to supply traction converters and lithium-ion based energy storage systems for 55 new bi-mode electric multiple units (BEMUs) ordered by Nahverkehrsverbund Schleswig-Holstein (NAH.SH) in northern Germany. These BEMUs represent a significant step towards modernizing regional rail transport. The traction converters, crucial components for converting electrical power for train propulsion, are designed for high efficiency, minimizing energy consumption and maximizing operational range. The integration of lithium-ion battery systems allows for operation on non-electrified lines, enhancing the flexibility and utility of these vehicles. The strategic decision to utilize lithium-ion batteries underscores the ongoing shift towards more sustainable and environmentally friendly power sources in the rail sector. The manufacturing process itself is noteworthy, showcasing ABB’s commitment to automation and efficiency with battery module production in Baden, Switzerland, and final energy storage system assembly in Minden, Germany.

Benefits for NAH.SH and BVG

The deployment of ABB’s technology brings substantial benefits to both NAH.SH and Berliner Verkehrsbetriebe (BVG). For NAH.SH, the new BEMUs provide a significant upgrade in terms of passenger comfort, operational efficiency, and environmental performance. The bi-mode capability extends operational reach beyond electrified lines, improving regional connectivity. For BVG, the implementation of ABB’s latest generation traction converters in over 600 new underground cars represents a complete modernization of their aging fleet. This upgrade will improve reliability, reduce maintenance costs, and enhance the overall passenger experience. The adoption of ABB’s equipment signals a strong commitment by both operators to sustainable and efficient public transport systems.

Technological Advancements and Economic Considerations

This project exemplifies the rapid advancement of battery technology and its increasing integration into railway systems. The use of lithium-ion batteries in BEMUs provides an efficient and reliable solution for extending operational ranges in areas lacking electrification. The high energy density of these batteries enables longer journeys without requiring frequent recharging. From an economic perspective, while the initial investment in advanced technology is substantial, the long-term operational savings from reduced energy consumption and decreased maintenance requirements make this investment economically viable. The semi-automated manufacturing processes employed by ABB contribute further to cost-effectiveness and scalability of the technology.

Environmental Impact and Sustainability

The shift towards electric and bi-mode trains represents a significant step towards reducing the environmental impact of rail transport. The adoption of ABB’s energy-efficient traction converters and lithium-ion batteries directly contributes to decreased greenhouse gas emissions compared to traditional diesel-powered trains. This project contributes to a larger trend in the rail industry towards sustainable practices, demonstrating a commitment to environmental responsibility and a reduction in carbon footprint. The utilization of renewable energy sources to charge the battery systems further enhances the environmental benefits.

Conclusions

The collaboration between ABB and Stadler highlights a significant trend in the railway industry: the increasing adoption of advanced technologies to improve efficiency, sustainability, and passenger experience. The supply of traction converters and energy storage systems for both NAH.SH and BVG showcases the practicality and economic viability of integrating cutting-edge battery technology into rail operations. The success of this project underscores the importance of continued innovation in power electronics and energy storage for achieving sustainable and efficient rail transportation. The use of lithium-ion batteries, along with highly efficient traction converters, demonstrates a commitment to reducing greenhouse gas emissions and improving air quality in urban and regional areas. The scalability and potential for standardization of this technology promise significant long-term benefits for the rail industry globally, paving the way for widespread adoption of similar solutions for modernization and expansion of rail networks worldwide. Furthermore, the success of this collaboration between ABB and Stadler serves as a model for future partnerships in the industry, demonstrating the potential for synergistic innovation and the efficient delivery of sustainable and cost-effective rail solutions.
