Road vehicles - Vehicle to grid Communication interface - Part 3: Physical and data link layer requirements (ISO 15118-3:2015)

ISO 15118-3:2015 specifies the requirements of the physical and data link layer for a high-level communication, directly between battery electric vehicles (BEV) or plug-in hybrid electric vehicles (PHEV), termed as EV (electric vehicle) [ISO-1], based on a wired communication technology and the fixed electrical charging installation [Electric Vehicle Supply Equipment (EVSE)] used in addition to the basic signalling, as defined in [IEC-1].
It covers the overall information exchange between all actors involved in the electrical energy exchange. ISO 15118 (all parts) is applicable for manually connected conductive charging.
Only "[IEC-1] modes 3 and 4" EVSEs, with a high-level communication module, are covered by this part of ISO 15118.

Introduction

The pending energy crisis and the necessity to reduce greenhouse gas emissions has led the vehicle

manufacturers to a very significant effort to reduce the energy consumption of their vehicles. They

are presently developing vehicles partly or completly propelled by electric energy. Thus, vehicles will

reduce the dependency on oil, improve the global energy efficiency, and reduce the total CO emissions

for road transportation if the electricity is produced from renewable sources. To charge the batteries of

such vehicles, specific charging infrastructure is required.

Much of the standardization work on dimensional and electrical specifications of the charging

infrastructure and the vehicle interface is already treated in the relevant ISO or IEC groups. However,

the question of information transfer between the vehicle and the grid has not been treated sufficiently.

Such communication is beneficial for the optimization of energy resources and energy production

systems as vehicles can recharge at the most economic or most energy-efficient instants.

It is also required to develop efficient and convenient payment systems in order to cover the resulting

micro-payments. The necessary communication channel might serve in the future to contribute to the

stabilization of the electrical grid, as well as to support additional information services required to

operate electric vehicles efficiently.
