ABB officially opened a new plant for energy storage systems for mobility applications today in Baden, Switzerland. The energy storage systems will be used in railways, e-buses/trolleybuses and e-trucks. The facility represents an important investment in Switzerland as a production location.
ABB has already received orders for energy storage systems from several vehicle manufacturers from different countries. Among other applications, they will be used in new trolleybuses in the Swiss cities of Zürich, Lausanne and Fribourg.
Energy storage systems are a key technology for the future of sustainable mobility and play an important role in the field of electrification and decarbonization of road and rail transport: Efficient energy stores are essential for the operation of electric buses and e-trucks and allow, for example, the braking energy generated by recuperation to be stored. Moreover, the energy storage systems increase the flexibility of trolleybuses as they can drive long distances without overhead lines thanks to this technology.
Unlike in Switzerland, many other European countries still have countless non-electrified railway lines. Integration of energy storage systems makes it possible to convert diesel trainsets into diesel hybrid vehicles, thus cutting CO2 emissions by 30% with the possibility of achieving significant energy savings through recuperation. Energy storage systems offer transport operators many options to retrofit their vehicle fleets for a more sustainable mobility.
Battery cells are assembled into standardized battery modules in production. These are combined into energy storage systems and configured according to the specific application. The products utilize the latest lithium-ion technology and are characterized by their high energy and power density as well as their long service life even under high loads. They are designed to be safe and highly energy-efficient.
Two ABB robots are used in the production process to ensure that high safety and quality requirements are met: one places the battery cells in the module housing and the other joins them by means of a highly precise laser welding process. All data in the production process is recorded digitally on a continuous basis.
ABB has many years of experience in energy storage systems for a wide variety of applications such as in power grids or solar systems. Baden was selected as the production location for different reasons including its proximity to the ABB Center of Excellence for Traction Converters in Turgi and to the ABB Corporate Research Center in Dättwil.
