Innovation Project - DEFev

Werenode is committed to advancing electric vehicle (EV) charging technologies and decentralized energy solutions by developing innovative components that leverage blockchain, IoT, decentralized identity, and cutting-edge user interfaces. This document highlights one of our key innovation projects: DEFev, DLT Ecosystem For Electric Vehicle Charging. We have also developed several other Web3.0 systems: DID-IMP, IOTPAY, DECO developed in collaboration with OP Mobility and SII, the Alexa Speech HMI version of Werenode, developed in collaboration with Renault's ElectroShaker Lab, and the LG Web OS version of our application, developed in collaboration with LG Nova.

DEFev - Decentralized EV Charging Management​

DEFev is a fully decentralized web application designed to provide a seamless user experience for managing EV charging using blockchain technology. DEFev aims to empower users with complete control over their EV charging transactions and data.

Key Features:​

  • Blockchain Payments: DEFev allows users to directly manage payments for charging using blockchain-based wallets, such as MetaMask. This ensures a secure and decentralized payment solution without intermediaries.
  • Web3 Integration: DEFev leverages Web3.js to directly interact with the blockchain, enabling users to connect their wallets and interact with Werenode's smart contracts for EV charging.
  • User Autonomy: The decentralized architecture means users have full control over their payments and transactions, with all interactions being transparent and recorded on the blockchain.
  • Multi-Chain Support: DEFev supports both Tezos and Binance Smart Chain tokens—Werecoin (WRC) and BWRC, respectively—providing flexibility for users.

Architecture & Protocol​

The architecture of DEFev comprises several core components:

1) Public Blockchain Network: Serves as the foundational layer, ensuring transparency and security. 2) Smart Contracts: Automate the management of the charging session and its payment. 3) Decentralized Wallet: DEFev is fully Web3.0 and utilizes Metamask. 4) User Interface: A web application to locate and identify the ev charging equipement, to trigger or interrupt the sessions, with additional features.

A simplified overview of DEFev architecture is showed below:

Collaboration:​

DEFev was developed within the NGI Ontochain framework. DEFev received funding for this: Grant Agreement Number 957338.

Benefits:​

  • Full Transparency: Transactions are recorded on-chain, ensuring full transparency for both charging station operators and EV drivers.
  • Secure Payments: By using blockchain wallets like MetaMask, DEFev eliminates the risk of intermediaries, ensuring fast and secure transactions.
  • Seamless User Experience: With the Plug&Charge feature, users can enjoy a simplified charging process, requiring minimal interaction to initiate a charging session.
