| 摘要 |
The invention relates to a charging device (100) for charging a battery pack (190), comprising a power unit (150) that can be connected to an input voltage source (105) for creating an electric output voltage (UOUT) for charging the battery pack (190), wherein the power unit (150) is associated to a display element (199) for displaying an electrically conductive connection between the power unit (150) and the input voltage source (105). A switching unit (180) is provided, which is designed to turn off the display element (199) when the established electrically conductive connection between the power part (150) and the input voltage source (105) is interrupted. |
