Abstract (en)

[origin: WO2011151124A1] The invention relates to a power supply, to a controller (5), and to a power element (1), wherein a DC compensation voltage (UL) is present at a first output (OUT1) of the power element (1), to which a load (3) having variable current draw can be connected. A second output (OUT2) of the power element (1) is thereby fed through a current measurement device, wherein a rechargeable battery (4) is connected to the said second output (OUT2). A charging current (IL) or discharge current of the rechargeable battery (4) measured by means of the current measuring device is set by controlling the DC compensating voltage (UL). The charging current or discharge current of the rechargeable battery (4) can thereby be determined even without a dedicated UPS assembly.
