INTRODUCTIONGrid Integration of Electric Vehicle Infrastructure

Introduction

� Grid integration of electric vehicle infrastructure is a prerequisite of smart charging.

� It must provide:

� the ability for an electric vehicle to integrate into the whole power system in a grid- and user-friendly way.

� must facilitate the security (reliability) of supply while meeting the mobility constraints and requirements of the user.

� To achieve those goals in a safe, secure, reliable, sustainable and efficient manner, information needs to be exchanged between different stakeholders.

Very “simple” and practical example

We talk about what?

� what is the „Electric Vehicle Infrastructure“ and the “Grid”?

� SIMPLE View:

� WHO may charge (access to charging infrastructure)

� WHAT shall be charged (EV Battery SOC, fast/slow/ …)

� WHEN shall be charged (controlled vs. uncontrolled)

� OTHER View:

� Where is the charging spot connected to

� Who is providing the energy

� Who is providing the charging service

� Who is providing the (local) infrastructure

� ICT is THE major part of it and works as „enabler“

� Players / Roles:

Electric Utility

Infrastructure / Hardware

Supplier

Software / IT ProviderSoftware / IT Provider

Summary on „challenges“

� Grid:

� Guarantee stability, quality and availability of an electric power grid

� preferable based on renewable energy

� preferable local/decentralized energy generation (PV) and storage

� Access:

� Enabling a flexible and ubiquitous charging infrastructure for electric vehicles that pay’s off

� Control:

� Substantial energy savings due to on-demand, flexible management of every electric vehicle connected to the grid

� user-friendly, flexible and cost-effective handling of energy brokerage features

� Support a variety of business models inline with national/regional legal regulations
