Abstract
A stationary storage device temporarily stores electric energy in an electric supply grid, and includes at least one electric storage unit, each electric storage unit being connected to a common DC bus by a respective DC-DC converter. The stationary storage device includes a bidirectionally operated AC-DC converter that couples the common DC bus to the electric supply grid, and a charging device that exchanges energy with an electrically operated motor vehicle. The charging device includes a connection device that connects the electrically operated motor vehicle in order to exchange the energy, and a charge control device that controls the exchange of said energy. A coupling device electrically connects the connection device to the common DC bus via one or more DC-DC converters in order to exchange said energy.
