ABOUT THE PROJECT

DEFev: DLT Ecosystem For Electric Vehicle Charging 

Leveraging the blockchain technology, we build an ecosystem that allows anyone to share his EV charging station. Thanks to a mobile app and smart contracts, you can get compensated when you give access to any other EV user to your own charging equipment. Hence we open a disintermediated marketplace to foster the EV charging network development. Our framework allows also a simplified path towards new services development (Plug&Charge, Smart Charge, V2G, Green electricity branding...) and EV charging station fleet management.

Use Case

 

 

 

Motivation for the project:

The DEFev project is building a blockchain framework to fully integrate the electric vehicle charging networks in the ONTOCHAIN ecosystem. Thanks to this, we develop a decentralized Peer-to-Peer EV charging solution.

Generic use case description:

A new member of the network wants to share his charging station. To register his plug, he declares a set of required information for the creation of the station record on the blockchain. He also chooses an EVSE manager for this new station, which will fully control each charging session, starting and stopping it. Each EV driver will now be able to use this charging station thanks to the Mobile App.

Essential functionalities:

EV charging session triggering and control through a Mobile App and a smart contract.
Payment of the charging session with a cryptocurrency.
Interoperable digitalization of the charging stations on the blockchain.

How these functionalities can be integrated within the software ecosystem:

These functionalities will be integrated in the Ontochain ecosystem through a Bellecour EVSE ledger smart contract and a dedicated traceability and payment token. Furthermore, DEFev will use some Ontochain tools like the identification application Gimly.  

Gap being addressed:

In a nutshell, we bring EV charging on-to-chain; thanks to this, we are able to uberize the EV charging business. Indeed, DEFev brings a new real-life application to the Ontochain framework.

Expected benefits achieved with the novel technology building blocks:

DEFev project resolves interoperability issues by providing a common infrastructure that integrates different parties into one unified ecosystem. The charging stations have digital twins in the blockchain, allowing to manage a micro charging operator as easily as a user, opening the path to seamless P2P charging.

Potential demonstration scenario:

An EV driver locates a compliant and available charging point that he wants to use thanks to the Mobile App providing the compatible charging points. The customer plugs his vehicle and charges. The connected station delivers the charging service during the expected amount of time.
