Vehicle-to-Grid for Renewable Energy Integration in Bangladesh: A Degradation-Aware Critical Review and Future Research Framework

This paper presents a degradation-aware critical review of Vehicle-to-Grid (V2G) technology for renewable energy integration in Bangladesh. The study systematically synthesizes recent evidence using PRISMA 2020 and SALSA frameworks, identifying key challenges related to battery degradation, EV mobility, renewable variability, distribution-grid constraints, economics, aggregation, and cybersecurity. The paper highlights Bangladesh-specific research gaps and proposes an integrated future research framework that combines renewable generation, battery health, EV availability, grid limitations, and techno-economic considerations for sustainable V2G deployment.
