Road vehicles - Vehicle to grid communication interface - Part 2: Network and application protocol requirements
|Publication Date:||10 September 2018|
|ICS Code (Electric road vehicles):||43.120|
This international standard specifies the communication between the electric vehicle (EV), including battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV), and the EV supply equipment. The application layer message sets defined in this revision of ISO 15118-2 are designed to support the electricity power transfer between an EV and an EV supply equipment.
The bidirectional electricity power transfer, use case of that was already included in edition 1.0 of part 1 but not included in part 2, was officially added to the scope of this standard. Herein edition 2.0 of part 2 defines the communication messages and sequence requirements for bidirectional power transfer.
Also the scope is widely extended in this revision, requirements of wireless communication for both conductive charging and wireless charging are defined. Additionally, requirements of communication for automatic connection device and information services about charging and control status are defined in this revision.
The purpose of this part 2 of ISO 15118 is to detail the communication between an electric vehicle communication controller (EVCC) and supply equipment communication controller (SECC). Aspects are specified to detect a vehicle in a communication network and enable an Internet Protocol (IP) based communication between EVCC and SECC.
This part 2 defines messages, data model, XML/EXI based data representation format, usage of V2GTP, TLS, TCP and IPv6. These requirements belong to the area of from 3rd to 7th OSI layer model. In addition the document describes main service sequences of conductive charging, wireless power transfer and bidirectional power transfer, and how data link layer services can be accessed from a layer 3 perspective. The data link layer and physical layer functionality for wired communication is described in part 3 of this standard, and those of wireless communication are described in part 8 of this standard.
