Claim:
1. A charging device, comprising: a power element to produce a charge voltage for charging a battery pack from an input voltage provided by an input voltage source to an input of the power element; a separator, the power element and the input voltage source being capable of being connected to one another in electrically conductive fashion via the separator; an allocated energy storage device; a control unit, the separator being controllable by the control unit, wherein the control unit is connected to the allocated energy storage device, at least for standby power supply, the separator configured to produce, in an allocated switching mode, an electrically conductive connection between the power element and the input voltage source and, in an allocated separating mode, to separate the electrically conductive connection and the control unit is configured to control the separator during transition from a charge operating mode to a standby operating mode of the charging device to change the separator over from the switching mode to the separating mode, wherein in the standby operating mode a supply of power to the control unit is provided by the energy storage device; and a housing in which are situated the power element, the separator, the energy storage device, and the control unit, wherein the power element transmits power outside of the housing by transmitting power to the battery pack located outside of the housing.
