Grid Integration of Electric Vehicle Infrastructure INTRODUCTION

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 Example of building architecture with EV charging infrastructure Building Gateway (BG Building Energy Manager (BEM Internet Solar Panel Smart Appliance Manager (SAM Power Distribution Smart Home DC/AC INVERTER 3phase AC Inverter ECU Smart Meter EV Supply Environment (1phase AC, 11kW Storage Rack Identification Unit 1phase AC AC/DC INVERTER DC/DC EVSE Comm. Unit Ethernet Inverter ECU BMS

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 Provider OEM POI / Navigation Service Provider
