Nexus' solution for protecting vehicle-to-grid communication (V2G) with PKI certificates is compliant with common standards and used in plug & charge applications. 

Plug & charge use case

The plug & charge functionality has the following goals: 

  • E-roaming: any e-vehicle with a contract from any mobility operator can charge at any charge point
  • Usability: effortless, cashless and transparent payment without the need for RFID or mobile identification
  • Smart tariffs, bill signing: the mobility operator signs bills - with dynamic tariffs - on behalf of the consumer
  • Smart charge control: charging profile can be prepared according to grid status

Roles 

The goal of V2G PKI is that the following parties can trust each others’ certificates and contracts:

  • Vehicle manufacturers (OEMs) provide IDs for e-vehicles (EVCCs) with plug & charge functionality.
  • Charge point operators (CPO) provide IDs for charge points (SECCs) with plug & charge functionality.
  • Mobility operator (MO) close contracts with consumers and provide signed electronic contracts for the e-vehicle, which are presented to the charge point for charging.
