Blockchain Based Management of Electricity Delivery

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a blockchain-based system for managing the delivery and payment of electricity at electric vehicle (EV) charging stations. It enables operators of charging stations to authenticate users, authorize charging requests, and manage accounting via a decentralized blockchain network using smart contracts. The system allows interoperability among different charging station operators, so users can charge their vehicles at any station with a single registration, while ensuring secure transactions and privacy using, for example, zero-knowledge proofs.

Use CasesContent extracted from patent full text and abstract with AI.

• Allowing EV owners to charge at any compatible charging station using a single account, regardless of the operator network.
• Streamlining authentication and payment processes at EV charging stations without the need for multiple contracts or roaming agreements.
• Secure and privacy-preserving verification of user credentials and payment information at charging stations.
• Automating inter-operator settlements and payments for cross-network EV charging sessions.
• Implementing decentralized, tamper-resistant user and transaction records for electricity delivery and billing.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables seamless charging for users across different operator networks with a single contract, improving convenience.
• Eliminates the need for centralized clearing houses or complex roaming agreements, reducing administrative overhead.
• Accelerates authentication and authorization at the point of charging by providing instant access to user data via blockchain nodes.
• Enhances security and trust through decentralized, tamper-proof transaction logs and the use of smart contracts.
• Preserves user privacy with mechanisms like zero-knowledge proofs, avoiding unnecessary sharing of sensitive data.
• Reduces transaction processing times and operational costs compared to current centralized or manual settlement methods.
