SecondLifeBatteries4Storage
A system for utilizing used batteries of electric vehicles as a stationary energy storage device
This research project has been completed. Access the SecondLifeBatteries4Storage Results Fact Sheet here.
Solutions that make renewable energies more usable and promote decentralised electricity production or electricity and heat storage are just some of the topics that are of great concern to the energy industry and which Green Energy Lab is addressing as part of the Energy Flagship Region initiative.
Objective of the SecondLifeBatteries4Storage project
Recycling batteries from the e-mobility sector – The basic idea behind the “SecondLifeBatteries4Storage” project is to reuse batteries that have already been used in the electromobility sector. These are often discarded when they have only 80% of their capacity left. However, they are still good for further use as electricity storage in stationary applications.
These second-life batteries can be combined into larger, stationary electricity storage systems and used to cover peak loads (“peak shaving”) as well as to optimize own electricity in the industrial sector. They can also be used for grid stabilization or as a blackout reserve. The use of energy storage systems is playing an increasingly important role, particularly for the optimal integration of electricity generated from renewable energy sources and for the cost-effective use of electricity. On the one hand, these storage systems are intended to delay the disposal of batteries with a sufficient state of health (the ratio of available capacity to nominal capacity and the future ageing behavior of batteries) and, on the other hand, to reduce costs for grid provision through lower peak loads.
Approach and methodology of the SecondLifeBatteries4Storage project
Mobile rapid analysis – As part of the project, a mobile rapid analysis device was developed for the rapid and cost-effective assessment of the condition of used batteries, as it is generally not possible to access the stored battery data directly without the vehicle manufacturer and thus determine the state of health. The special feature of this product is its cross-brand functionality for measuring a wide variety of batteries. If the batteries have a sufficiently high state of health, they are installed in stationary accumulator packs. In addition, a software tool was developed to comprehensively determine the residual value, which includes all process steps (first-life, reconditioning, second-life, recycling). For practical application, a so-called automatic storage dimensioning tool is required, which can optimally dimension the storage system for a wide range of applications (peak load coverage, PV self-consumption optimization, etc.). This dimensioning tool was also developed as part of the project.
Outlook
The work programme aims to create optimal conditions for a free market for second-life batteries from the electromobility sector and to realize both ecological and economic benefits by exploiting the potential of used battery systems for storage applications. The project thus made a decisive contribution to implementing affordable and sustainable energy systems.

SecondLifeBatteries project successfully completed
The aim was to enable the continued use of e-car batteries that are no longer suitable for use in vehicles as power storage units in stationary applications. At the same time, special instruments were developed to determine the condition and state of health of the e-car battery. The resulting independence from the battery manufacturer creates the conditions for a free market for second-life batteries.

The SecondLife-Batteries4Storage project is funded by the Climate and Energy Fund and carried out jointly with the Graz Energy Agency as part of the "Green Energy Lab" Flagship Region. The project is about a large-scale electricity storage system that consists entirely of old electric car batteries.

Batteries in electric cars are usually discarded when they only provide 80 percent of their power. Until now, they have had to be disposed of and recycled, but a Graz-based consortium wants to give them a second life. AVL List, AVL DiTEST, Energie Steiermark, Grazer Energieagentur, Saubermacher and Smart Power used the batteries to build a large-scale electricity storage system independent of original equipment manufacturers (OEMs). The project was completed on Tuesday.
