A real world technology testbed for electric vehicle smart charging systems and PEV-EVSE interoperability evaluation

Global sales of electric vehicles passed the 1 million unit mark in 2015. These grid-sourced electric vehicles operators require reliable access to seamless delivery of electricity to their vehicles for dependable transportation. Electrical utilities and other electrical distribution infrastructure owner/operators require the electrical vehicles using their services to be non-disruptive with reasonable return on investment revenues. Standards Defining Organization (SDO) committees are composed of subject matter experts that formalize requirements for the respective standards topic, based on needs of the stakeholders. Validation of standards, component-system compliance to standards, and interoperability of systems between standards requires testing. This testing can be simulation or model based as well as component and system level evaluation. This paper describes requirements and challenges to build a real-world testbed for EV-smartgrid interoperability assessment. AC, DC, and Wireless charging methods are addressed as well of balance of system topic such as grid impacts, metrology, dispatch of resources, and vehicle-infrastructure communication.
