摘要
The invention relates to an electrical stationary storage device (23) for temporarily storing electrical energy in an electrical supply network (10), comprising: at least one electrical storage unit (19), each storage unit (19) being connected by means of a respective DC-DC converter (18 ') to a common DC bus (22) is connected, and a bidirectionally operable AC-DC converter (17 ') for coupling the DC bus (22) to the supply network (10). The invention provides that the stationary storage device (23) for energy exchange with an electrically operable motor vehicle (13) has a charging device (25) having a connection device (14) for connecting the motor vehicle (13) for the energy exchange and a charge control device (15 ) for controlling the energy exchange, wherein a coupling device (K) is provided, which is arranged, the connection device (14) at least for the exchange of energy via one or more than one DC-DC converter (18, 18 ') with the DC -Bus (22) to connect electrically.
