CO2-freier Personen- & Güterverkehr auch ohne Oberleitung.

Wide variety of customised solutions for emergency power and traction applications in the rail sector.


We offer you a wide range of applications

Spurs and secondary lines are often not electrified. Our rail traction solutions allow you to bridge sections of the track where there are no overhead lines or to open up spur lines. By using battery-based rail traction systems you can utilise the full performance of electrically powered trains even on these sections of the rail network. At stations that are only partially electrified, emission-free and low-noise shunting can even be carried out on secondary lines.

Our batteries can also be used for tunnel rescue locomotives. Because of the environment in which these trains operate, they must be emission-free.Get quote »  

By using our innovative rail traction products, you will be reducing the amount you spend on costly fuels, such as diesel. Depending on the vehicle type, you can save several tens of thousand litres of diesel a year.

Railway vehicles with diesel engines account for approximately 1 % of traffic-related black-carbon emissions. Although only a relatively small number of these diesel trains are in use, and usually just for shorter distances, the advanced age of these locomotives and their long hours of operation mean that they are responsible for high levels of emissions in urban areas. This applies to railway stations, for instance, especially to low-level stations such as Stuttgart 21, and in locomotive sheds. By opting for an alternative power source, such as our rail traction batteries, you will be looking after the environment by reducing CO2 emissions – and saving money as well.

Diesel-powered passenger trains are responsible for massive noise pollution in an urban environment. Battery-powered trains significantly reduce the noise nuisance in cities and especially at railway stations.
Diesel-powered railway vehicles, such as specialist and track-laying machines, OLE or tunnel maintenance vehicles, generate noise while they are working. By using our lithium-ion-based battery systems you can achieve an enormous reduction in the noise nuisance caused by the operation of these vehicles.

In passenger trains, underground trains and trams our batteries are used for diesel/electric hybrids, solely battery-operated vehicles and fuel-cell hybrids.

Why should you choose us?


Maximum performance guaranteed

Unsere Lithium-Ionen-Batteriesysteme lassen sich durch Auswahl unserer High-Energy- oder High-Power-Module flexibel im Hinblick auf eine hohe Reichweite oder eine hohe Leistungsfähigkeit optimieren. Unsere Systeme sind modular aufgebaut und werden für Ihr Fahrzeug individuell entwickelt. Hierbei greifen wir auch auf bewährte Konstruktionsprinzipien und Module aus unserem Baukasten zurück.

Large lithium-ion batteries represent a potential risk for people and for the environment. We have developed a safe battery system on the basis of extensive risk analyses. In doing so, we have taken not only active measures, such as safe operation of the battery system by implementing the Battery Management System, but also passive safety measures, such as fire-proof battery enclosures. Furthermore we have a filter system that binds the toxic substances released if the battery system is damaged.

Our systems meets all of these normative requirements applicable to a railway traction battery system. Independent, accredited laboratories have established and officially verified our compliance with all the safety-relevant norms and standards.


You can depend on us


It all fits

We offer you tailor-made solutions
Your satisfaction as a result of our customised solutions is of prime importance to us. Due to the modular design of our systems, there are no limits regarding your requirements. Together we can develop a solution that is tailor-made for you.

Our lithium batteries are low-maintenance. Apart from the annual safety check, only the air-conditioning unit required to ensure optimum operation of the battery system must be serviced once a year.


Focus on more important matters


So you can keep track

Wir ermöglichen Ihnen smartes Daten-Monitoring und Batterieüberwachung auf höchstem Niveau. Mit unseren fortschrittlichen Tools haben Sie auch bei größten Datenmengen immer den Überblick. 

Sollte doch einmal etwas nicht wie vorgesehen funktionieren, so beginnen unsere Techniker schon im Vorfeld eines Service-Einsatzes mit der Fehleranalyse durch die Analyse der Batteriedaten. Anhand der Batteriedaten können wir Sie bestens beim Einsatz der Fahrzeuge beraten und Ihnen durch ein angepasstes Betriebsregime maximale Energieeinsparungen und einen optimalen Betrieb des Batteriesystems ermöglichen.
