Energy storage systems and traction converters for trains in Germany

ABB has won orders from Swiss rail vehicle manufacturer Stadler for propulsion technologies that will provide energy-efficient and sustainable transport solutions for the Schleswig-Holstein public transport network (NAH.SH) in northern Germany and the Berlin public transport company (BVG) in the German capital. The scope of supply includes energy-efficient traction converters and on-board energy storage systems based on high-performance lithium-ion battery cells.

"We are very pleased to be the partner of choice for Stadler Germany. We thank the company for its confidence in ABB's innovative traction equipment, with which we are making an important contribution to more sustainable mobility," said Edgar Keller, head of ABB's Traction division. "Our energy storage systems and our portfolio of high-efficiency traction inverters complement each other perfectly. We combine our many years of experience in the battery sector with extensive expertise in drive technology to develop innovative solutions for our customers."

ABB's traction converters and lithium-ion-based energy storage systems will be installed in 55 new battery electric multiple units (BEMU) for the Schleswig-Holstein public transport network. This is the largest single order for BEMU worldwide to date. The battery modules will be manufactured at ABB's state-of-the-art module production facility in Baden, Switzerland, and integrated into energy storage systems at ABB's drive technology plant in Minden.

The new trains will run on a partially electrified network, the longest non-electrified section of which is 80 kilometres long. So far, diesel-powered trains have been used in this network. The use of powerful and durable energy storage systems with high inherent safety ensures the same performance in all operating modes of the vehicles and increases safety. The charging of the traction batteries takes place on the electrified sections and at selected points on the line. In addition, the energy storage system can be charged at 400 volts or 1,000 volts via the depot supply. Thanks to ABB's unique traction converter architecture, all operating and charging modes can be implemented with the same power electronics that AC electric multiple units (EMUs) require anyway.

In Berlin, the latest generation of traction converters will be installed in more than 600 underground cars operated by Berliner Verkehrsbetriebe (BVG). The 30-year-old fleet is being replaced by modern vehicles with customised ABB technology to ensure more reliable and efficient operation and to cope with increasing passenger numbers. ABB's traction technology has proven to be extremely reliable in Stadler's IK series metro trains, which are already in service for BVG.

ABB has been supplying the rail sector with innovative and energy-efficient technologies for many years. The company manufactures and maintains components and subsystems used in rail vehicles and infrastructure for mass transit, mainline and high-speed lines. ABB also provides lifecycle services, including maintenance and retrofit, for its extensive global installed base.
