Abstract
Power management () for controlling a delivery of a DC-power to a device () operable in an accepting operational state or a non-accepting operational state with respect to receiving the DC-power comprises: receiving DC input power; providing an indication that the DC-power supply device () operates in a powered-device detection mode and not in an powered-device operation mode; connecting, when the DC-power supply device () is in the powered-device detection mode, the power to an energy storage unit (); storing electrical energy currently received; determining, whether the power-acceptance criterion is fulfilled and, in case it is fulfilled, providing an instruction to operate in the accepting operational state; connecting the energy storage unit () and a power interface unit () when the external DC-power supply device () is currently operating in the powered-device operation mode. This reduces DC-power consumption of a DC-powered device () by reducing or eliminating its DC-power consumption while it is operating in the non-accepting operational state.
