This paper presents the implementation design of a blockchain-based decentralized wallet system for electric vehicle (EV) charging stations with comprehensive feasibility analysis and performance projections. The system addresses key challenges in the EV charging ecosystem, including payment fragmentation, high transaction fees, security concerns, and lack of interoperability. We propose a solution using Ethereum blockchain technology that enables seamless cross-network payments, transparent billing, and peer-to-peer energy trading. Our implementation approach incorporates wallet management, authentication using decentralized identities, automated payment processing, and real time monitoring capabilities. The feasibility analysis demonstrates potential transaction cost reduction of 65-80%, settlement time improvement from 2-3 days to 15-30 seconds, and security enhancement through cryptographic protocols. Performance projections indicate the system can handle 10,000+ concurrent charging sessions with 99.9% uptime. The proposed implementation provides a viable and economically feasible model for addressing interoperability challenges in EV charging infrastructure while enhancing user convenience and reducing operational costs.
