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.

Key

1 Scope of ISO 15118-2

2 Message definition considers use cases defined for communication between SECC to SA

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.

This document defines the requirements and operation of the on-board vehicle equipment that enables magnetic field wireless power transfer (MF-WPT) for traction battery charging of electric vehicles. It is intended to be used for passenger cars and light duty vehicles.

This document addresses the following aspects for an EV device:

— functionality with associated off-board systems under various conditions and independent from manufacturer;

— transferred power and power transfer efficiency;

— ground clearance and positioning of the EV;

— safety requirements;

— test procedures.

EV devices that fulfil the requirements in this document are intended to operate with supply devices that fulfil the requirements in the IEC 61980 series.

NOTE 1 This edition covers stationary applications (vehicle is not in motion).

NOTE 2 Reversed power transfer is not considered in this edition.
