Methodology:   The study was conducted using an abductive research approach,   employing qualitative methods. The theoretical framework was developed through a systematic literature review of existing literature within the research scope. Data collection involved an  extensive literature review and archival study. Thematic analysis was applied to the data to identify patterns and themes, which were further analyzed to construct a framework.                                                     Conclusion:   The study concludes that integrating industry 4.0 technologies enhances the management and repurposing of EV batteries for second-life applications. These technologies enable effective monitoring, predictive maintenance, and secure data management, which supports ecosystem actors in developing sustainable and economically viable second-life business models.
