Smart managed charging (V1G) field demonstration in KEPCO

Korea Electric Power Corporation (KEPCO) has been leading a project on electric vehicle - power grid Integration (VGI) for smart managed charging (V1G) and bidirectional power transfer (V2G) system development and demonstration as a fast-demand response resource. KEPCO has developed VGI management system(“kVGI”) for V1G and V2G control. To use EV batteries as a useful flexibility resource through V1G, we developed a battery state of charge (SoC) reading device and estimation model for conventional EVs. Also, we developed and installed 100 EV supply equipment (EVSE) for V1G demonstration. In this article, we present some early results of V1G fielddemonstration of more than 100 EVs.
