The increasing adoption of electric vehicles (EVs) and integration of renewable energy sources present challenges in energy management and trading that require innovative approaches beyond traditional centralized models. This paper examines the efficacy of employing blockchain technology, the InterPlanetary File System (IPFS), and RSA-encrypted Non-Fungible Tokens (NFTs) to create a decentralized energy trading management system for EVs. By leveraging these technologies, the proposed system addresses the lack of transparency and inefficiencies in traditional models by ensuring secure, transparent, and efficient interactions among energy producers, consumers, and grid operators. The financial viability of implementing this system is evaluated by analyzing transaction fees across various Ethereum Virtual Machine (EVM)-compatible platforms including BNB chain, Fantom, Polygon and Celo for stimulating and identifying cost-effective solutions for the integration of these advanced technologies.
