Abstract
The invention refers to an exchangeable power-supplying unit (200, 300) arranged to supply electric power to a device (100, 400).

The additional functionality is accomplished by one or several processing units (220, 312, 319) contained in the power-supplying unit (200, 300) for pre-processing information, which is subsequently communicated from the power-supplying unit (200, 300) to the device (100, 400).
