Analysis and Evaluation of Methods to Reduce Test Duration and Effort for Second-Life Batteries

The growing demand for sustainable energy solutions highlights the importance of repurposing used lithiumion batteries for second-life applications. However, lengthy and resource-intensive testing processes pose significant challenges to the economic and technical feasibility of these solutions. This study aims to address these issues by systematically compiling, analyzing and comparing existing methods to reduce testing duration and effort for used batteries. The research involves evaluating various approaches to identify the most promising methodologies. Selected methods will be further validated under laboratory conditions to assess their feasibility and scalability for real-world applications. The goal is to develop optimized testing protocols that balance efficiency, accuracy and reliability. By providing insights into the strengths and limitations of current methods, this work seeks to contribute to the advancement of second-life battery markets, enabling more sustainable and resource-efficient energy storage solutions.
