An E-Clearinghouse for Energy and Infrastructure Services in E-Mobility

Sustainable mobility, based on battery-powered electrical propulsion concepts, has been rediscovered in 2008 through emerging technology developments and enviromental requirements. Since 2009 a charging infrastructure for transportation on the basis of electrified powertrains has been developed all over Europe. Access to the charging stations is monitored by intelligent Triple-A-Systems (AAA - Authentication, Authorisation and Accounting) for reasons of security, customer loyalty and accounting. Similar to roaming in mobile communications, it should be possible for pioneers of e-mobility to have access to public charging stations of different operators. This article describes an efficient and future-oriented architecture of Clearinghouse systems that will provide interoperability and information exchange for e-mobility applications.
