Coexisting V2G PLC between G3 and HomePlug GP using Dual PHY

Broad-Band PLC like as HomePlug Green PHY (GP) and the other Narrow-Band PLC like as G3 are candidates of V2G PLC standard. These PLC candidates are different bandwidth, so they cannot coexist at the same network. Therefore, it is needed to support coexistence technology for PLC. In this paper we propose “G3-GP Dual PHY” which can be used with different bandwidth G3 and HomePlug GP (HPGP). G3 and HPGP, each representative charging method of different bandwidth, can coexist in a single EVSE using G3-GP Dual PHY.
