V2G Wireless Authentication Solution and Test Framework for
Smart Charging
www.nemo-emobility.eu
Development of WAS capable SECC Association and pairing sequence
Overview
• New draft version of ISO 15118 introduces authentication over WLAN
• Wireless authentication is a novel method for EV authentication
• Challenges in wireless case: association, authentication and authorization
• EV association is a trivial task, if the charging cable is already connected
Wireless Authentication Solution (WAS) and TTCN-3 based test framework have been
developed
• Prototypical implementation of parts of the ISO 15118-2 2nd edition / ISO 15118-8
• Focusing on certificate based authentication
• Runs on embedded system environment
WAS uses standardized messages
• Seamless authentication without driver actions
• Standard for international authentication interoperability
WAS is validated by the independently developed test framework
EV – Electric Vehicle EVCC – Electric Vehicle Communication Controller EVSE – Electric Vehicle Supply Equipment SECC – Supply Equipment Communication Controller
Test framework • ISO 15118-4 contains conformance test cases
for wired charging
• Testing and Test Control Notation version 3 (TTCN-3) based test scripts have been customized
