Interface description Version DOC_DATE
Plug&Charge(PnC) Ecosystems enable EV OEMs, Mobility Operators and Charge Point Operators to use the ISO 15118 standard for the Plug&Charge functionalitie. PnC-Ecosystems manage certificates from V2G-, OEM- and MO PKIs. It manages the publication in pools and offers signing services for trusted data. V2G Root CAs like the the Hubject V2G Root CAs are the trust anchor for all participants of ISO 15118. The V2G-, OEM- and MO-CAs are published in the Root Certificate Pools of a Plug&Charge Ecosystem. It is possible to operate also parts like just a RCP, PCP, CPS, CCP or PKI Signing Services
The interfaces of the OPCP are fully compatible with ISO 15118-2: 2014 and the VDE application rule (“VDE Anwendungsregel”). It is also fully interoperable for all relaying parties. The specific implementation/description is based on international best practices, security of communication and protection of data.
The Ecosystem components can be divided into two main categories:
- The Plug&Charge Certificate pools and Certificate Provisioning Service
- The Plug&Charge PKI Services
- The Plug&Charge Callback Service
Plug&Charge PKI Services are managed service of V2G Root Operators like Hubject (Europe & North America), to provide all necessary certificates for EV OEMs, Mobility Operators, Certificate Provisioning Services and Charge Point Operators.
The Certificate pools and Certificate Provisioning Service are for publishing certificates and contracts between all ISO 15118 involved backends.
