Purpose of the research: This study examines the potential of Vehicle-to-Load (V2L) technology as a practical tool for enhancing grid loadflexibility through decentralized energy support. Special emphasis is placed on the influence of battery characteristics on V2L effectiveness.Methodology: A comprehensive technical and comparative analysis is conducted, focusing on key battery-related parameters that affect V2L performance. These include usable capacity, inverter constraints, thermal regulation, and degradation behavior. The study evaluates three dominant battery chemistries—lithium iron phosphate (LFP), nickel manganese cobalt (NMC), andlithium titanate (LTO)—and three major cell formats (prismatic, pouch, cylindrical) to assess their suitability for real-world V2L use cases.Results: LFP batteries demonstrate the best overall trade-off between safety, durability, and cost-efficiency under partial load conditions typical for V2L. Inverter limitations and thermal management are shown to significantly affect performance and longevity. Among cell formats, pouch cells are more vulnerable to thermal stress, while prismatic cells perform more consistently under moderate cycling regimes.Conclusions: V2L technology offers a viable and increasingly accessible pathway to improve household-level energy autonomy and reduce strain on centralized grids during peak periods. The growing availability of commercial EVs equipped with LFP batteries strengthens the case for integrating V2L into smart grid strategies aimed at increasing load flexibility and resilience.
