Abstract
A charging device, for charging a battery pack, can be combined with other charging devices to form a multi-charger. The charging device has an input-side contact element for a power cable or an additional charging device connection. Internally, the charging device has conductors for the electrically conductive connection of the input-side contact element to an output-side contact element and for looping through a power supply voltage in contact with the input-side contact element. A charging device circuit of the charging device is internally connected to the looped-through supply voltage. The charging device circuit includes an input side voltage converter and a charging controller for charging a battery pack. The supply voltage can be converted by the voltage converter into a supply voltage for feeding the charging controller.
