Last week, Zpark Energy Systems, Einride, Chalmers University of Technology, and RISE gathered at Zpark’s R&D facility in Luleå to conclude their joint research project on sustainable energy storage. Launched in 2022, the project has explored how second-life batteries from electric vehicles can be reused as stationary energy storage systems for charging heavy electric trucks. The aim has been to develop circular business models and technical solutions that reduce strain on the power grid while improving the cost-efficiency of electrified transport systems.
During the final demo in Luleå, the partners presented the project’s results and demonstrated the R&D prototype developed within the collaboration showing how repurposed batteries can provide efficient, sustainable energy storage to support heavy transport charging.
"This project has demonstrated that it is technically possible to integrate second-life batteries into charging infrastructure for heavy transport. The insights we’ve gained will guide our continued development of circular and scalable energy systems", Jimmy Abrahamsson says, CEO of Zpark Energy Systems.
"The project transformed our ideas into real-world know-how. Working with second-life batteries helped us build the models, insights, and expertise needed to make repurposed truck batteries a powerful, sustainable alternative. Proud of what we achieved with our amazing partners", Louise Söderlind de Ridder says, Public Funding & Policy Manager, Einride.
From the academic research community, Chalmers emphasizes the scientific value of the work:
"The project fills an important gap in research by focusing on a closed-loop repurposing case for used truck batteries and empirically investigating the feasibility of such a system", Patricia van Loon says, Associate Professor, Chalmers University of Technology.
RISE highlights the role of experimental research in advancing circular battery solutions:
"Experimental research initiatives such as this project are key to unlocking circular battery solutions, showcasing both the possibilities and challenges ahead, and driving sustainable, collaborative business ecosystems", Sara Fallahi says, Director for Strategic Research, RISE.
A foundation for circular and scalable energy systems
The successful completion of the project marks the end of a multi-year collaboration. The findings will be used to inform future research and potential commercial applications aimed at developing circular, cost-effective, and grid-supporting energy storage solutions for heavy transport.
About the project
The project is funded by FFI (Strategic Vehicle Research and Innovation) a collaboration between Vinnova, the Swedish Energy Agency, and the Swedish Transport Administration, together with the Swedish automotive industry. It is conducted by Zpark Energy Systems in collaboration with Einride, Chalmers University of Technology, and RISE.
