This paper explores the implementation of blockchain technology in managing energy transactions for electric vehicles (EVs), addressing the inefficiencies of traditional energy systems. Through a detailed examination of various encryption algorithms and EVM-compatible blockchain platforms, we assess the potential of blockchain to enhance the transparency, efficiency, and security of energy trading. Our analysis focuses on the attributes of blockchain technology such as decentralization, immutability, and transparency, which are essential in environments lacking centralized oversight. The study also evaluates the economic feasibility of blockchain applications in the energy sector by examining transaction fees across different platforms. By integrating blockchain with advanced cryptographic techniques and decentralized data storage solutions like the IPFS, we propose a framework that could significantly improve the management of energy transactions, reduce operational costs, and enhance the reliability and integrity of the energy market for EVs.
