Tsubaki’s upgraded eLINK® is now a V2X-compatible virtual power plant / EV charging station
Smoothly Connecting EV and PHEV with a Network of Power and Information
Can be used as a virtual power plant (VPP) resource or an emergency power supply in the event of power failure
Tsubakimoto Chain Co. (President: Yasushi Ohara, Headquarters: Kita-ku, Osaka) 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”) EVs with the powerids of public facilities, buildings, factories, and other facilities via a quick charging connector for EVs electric vehiclesction can also be used as a virtual power plant (VPP) to supply power from the EV battery back to an electric grid.
The Tsubaki eLINK, originally released in 2013, has been utilized mainly at public facilities as a combination vehicle-to-building (V2B)-compatible power supply and EV charging station used for emergency power supply in the event of a power outage and to reduce regular power consumption when electrical demands are at their highest (peak hours).
This new eLINK model functions as a SiC-based bi-directional inverter for power conversion from EVs. In addition, it has improved outdoor visibility and user-friendliness thanks to the design innovation of the main unit and touch screen. This V2X-compliant product for business applications integrates the company’s experience and technology, including years of connection records from the energy management systems of buildings, and participation in Japan’s first demonstration of the use of EVs as a VPP source.
