Abstract

This paper presents a smart DC micro-grid system for plug-in electric vehicle charging and discharging. This DC microgrid integrates the plug-in battery electric vehicles (BEVs) & plug-in hybrid electric vehicles (HEVs) together with the AC supply module, storage energy module, and intelligent control module. By connecting with the AC power source and the storage energy module, this grid can offer three types of DC bidirectional interfaces for the plug-in EV charging and discharging. Hence, according to the commands from the intelligent control module, the power in the grid can smartly distribute to the desired plug-in EVs. The system configuration and the testing model are discussed and analyzed.
