Second battery life – TAURON launched an innovative energy storage facility.
TAURON launched the first energy storage facility in Poland, which was created using used batteries from electric buses. The warehouse with a power of 150 kW and a capacity of 150 kWh is located in Jaworzno and already cooperates with the power grid.
Patryk Demski , vice-president of the TAURON Group for strategy and development, said:
Batteries in electric buses lose some of their capacity and efficiency as a result of their use. Batteries with a capacity below 80 percent, which are no longer useful in buses, can become an excellent element of stationary electricity storage.
“The second life of batteries is therefore an extension of their useful life by at least 8 years. During the project implementation, we checked how the warehouse works with an electric vehicle charger and how it affects the parameters of the local power grid. We plan to further analyze the operation of the warehouse and verify the possibility of its integration, for example, with the Group’s production sources”
For several years now, we have been observing an increasing number of electric buses in use on the Polish market. The standard service life of battery modules in an electric bus is 8 to 10 years. Taking into account the development of electromobility in public transport, in the coming years we will observe a significant increase in available second-life battery packs. By using them in a stationary warehouse, the battery life cycle can be extended by up to 8 years. Thanks to this, instead of being disposed of, they will be recycled.
The warehouse is the first industrial Second Life warehouse in Poland using used battery packs. The warehouse is directly connected to the power grid, it is composed of four battery modules with 78 individual battery cells each, each module weighs about 500 kilograms, they come from the first electric bus operating in Jaworzno.
Patryk Demski, explains:
“Energy storage using lithium-ion cells will constitute an important element of intelligent power infrastructure. Small storage facilities are an effective tool for stabilizing the operation of power grids, especially in low-voltage networks, where the share of energy from unstable renewable energy sources is growing dynamically, and are also an important element of the system of microgrids or energy cooperatives . Lithium-ion cells from buses may play a significant role here due to the expected increasing supply of used batteries and lower construction costs compared to classic industrial warehouses.”
The project is co-financed by the European Union from the European Regional Development Fund under the Smart Growth Program. Project implemented as part of the competition of the National Center for Research and Development: Measure 1.2 “Sectoral R&D programs” under Priority Axis I “Support for R&D work by enterprises”. Project called “Development and testing of an adaptive electric energy storage system based on the second life of batteries from electric vehicles.”
