Patent ID: 8018182

Claim:
A method for detecting an overload situation in a battery-powered hand-guided power tool ( 10 ) equipped with an electric motor ( 12 ) and a DC battery pack ( 14 ) for supplying an operating current (I B ) to the electric motor ( 12 ), in particular for a battery-powered hand-guided power tool ( 10 ), in which the operating current (I B ) of the electric motor ( 12 ) is determined, wherein a difference (I D ) between the value of the operating current (I B ) and at least one stored current value (I G ) is determined, in association with a maximum set point duration (t a ), which maximum set point duration (t a ) defines a maximum duration of said overload situation by taking into account an operating temperature (T 0 ) of the hand-guided power tool ( 10 ), particularly at a moment at which the tool is switched on, and based on the difference (I D ), a conclusion is drawn as to whether a thermal overloading of the power tool ( 10 ) is occurring.
