V2G PKI

Also called: Plug & Charge PKI, Public Key Infrastructure V2G PKI is the certificate and trust infrastructure used by ISO 15118 Plug & Charge to authenticate participating vehicles, contracts and charging systems. It provides the chain of trust behind the automatic authorisation seen by the driver. Contract certificates identify the charging contract presented by the vehicle. Other certificates are used within the wider system so that software can verify who issued a certificate and whether it should be trusted. CharIN maintains certificate policies for first-generation PKI aligned with ISO 15118-2 and second-generation PKI aligned with ISO 15118-20. The PKI is part of the implementation around Plug & Charge, rather than the charging connector itself.
