Diamond Electric Holdings Co., Ltd. is installing a Stellantis' electric vehicle equipped with DE's V2X AC capable On-Board Charger (V2X OBC) in California to
demonstrate its V2X capabilities, including charging, discharging, and supporting grid through the V2X OBC. In July 2021, DE reached an agreement with Stellantis to participate
in a demonstration of Vehicle-to-everything using Alternative Current (V2X AC), then in August 2022, DE developed a V2X AC capable On-Board Charger (V2X OBC). As electric vehicles (xEVs) and distributed energy resources (DERs) become more prevalent, there are concerns about grid instability due to excessive electricity demand from recharging
xEV and over/under generation of renewable energy. Therefore, V2G (Vehicle-to-Grid) is expected as a next-generation technology to stabilize the power grid by discharging
electricity from the storage batteries of xEVs into the grid. In addition, V2H (Vehicle-to-Home, electricity backup for a house), which utilizes the batteries of xEVs as a backup power source in the event of a power outage, and V2X, which collectively refers to V2G, V2H, etc., is drawing increasing attention. In V2X AC, one of the V2X systems, the OBC installed in the xEV charges and discharges, stabilizes the grid through its grid support functions, and provides backup electricity in case of power outages. Therefore, the OBC is required to operate as an inverter and have functions required by grid interconnection rules.
