Tsubakimoto Chain Co., Ltd. has upgraded the Tsubaki eLINK, a vehicle-to-everything (V2X) compatible, vehicle-to-grid (V2G) / electric vehicle supply equipment (EVSE) charge point device that bi-directionally connects electric vehicles (EVs, including PHEVs (plug-in hybrid vehicles), hereafter collectively called EV) with the power grids of public facilities, buildings, factories, and other facilities via a quick charging connector for EVs. The eLINK connection can also be used as a virtual power plant (VPP) to supply power from the EV battery back to an electric grid.
