Battery leasing, which allows electric vehicle (EV) users to lease batteries independently of vehicle ownership, has emerged as a promising strategy to reduce upfront costs and accelerate EV adoption, particularly in emerging economies. This study seeks to identify and validate the critical enablers that can facilitate the implementation of battery leasing models within India’s evolving EV ecosystem. An initial pool of 48 enablers was derived through a comprehensive literature review and subsequently refined to 29 through frequency mapping. To systematically validate these enablers under expert uncertainty, the Fuzzy Delphi Method (FDM) was employed, engaging a panel of experts from both academia and industry with domain-specific knowledge in EV battery systems, energy policy, and mobility solutions. Based on consensus thresholds and defuzzification, nine enablers were confirmed as most influential, including targeted leasing policies, optimized charging modes, integrated leasing platforms, and circularity integration. The findings offer strategic insights for policymakers, EV manufacturers, and infrastructure developers. The study also outlines key limitations and suggests future research directions focused on empirical validation and implementation modeling.
