Abstract (en)
[origin: WO2021121813A1] The invention relates to an electric processing tool, comprising an energy supply device (10) and an open-loop or closed-loop control unit (30), the energy supply device (10) having at least two energy sources (12, 14, 34) which are interconnected, each in a series circuit with an electronic component (18) for ORing the individual current (I1, I2, In) of the electronic component in question, to form a common star point (20), such that a resulting total current (IS) for supplying the electric processing tool (12) results. According to the invention, at least a subset of the energy sources (12, 14, 34), in particular each energy source (12, 14, 34), is assigned a current-measuring unit (26) for measuring the individual current (I1, I2, In) of the energy source (12, 14, 34) in question, the open-loop or closed-loop control unit (30) adapting the total current (IS) to the measured individual currents (I1, I2, In).
