Sekisui Chemical Co Ltd released the "Grand Two U V to Heim," a wooden smart house that links an electric vehicle (EV) and a solar power generation system with an output capacity of 10kW or higher in the aim of realizing practical energy self-sufficiency, May 1, 2014.
By appropriately controlling a solar power generation system and the rechargeable battery of an EV, it enables to provide up to 75% of the amount of electricity consumed by the entire house throughout the year.
Conventional "V2H" systems, which provide electricity from an EV to a house, have various limitations. For example, when electricity is supplied from an EV to a house, it is necessary to temporarily cut off electricity from the power grid. On the other hand, to solve such an issue, the Grand Two U V to Heim comes with a grid connection system that also controls an EV and a solar power generation system.
