Abstract (en)
This electric tool is provided with: a battery pack (1) that includes a battery cell; and an electric tool main body (3) in which a driving unit (4) is driven by power supplied from the battery pack (1). The electric tool main body (3) is provided with a controller (5) that controls the driving unit (4). The battery pack (1) is provided with: a rated voltage storage unit (12) at which information of a rate voltage of the battery pack is stored; a rated voltage information output unit (13) that outputs the information of the rated voltage stored at the rated voltage storage unit to the controller (5); a battery temperature detection unit (14) that detects the temperature of the battery cell (11); and a detected temperature output unit (15) that outputs the temperature value detected by the battery temperature detection unit (14) to the controller (15). The controller (5) limits the output of the driving unit (4) when the temperature value of the battery cell (11) exceeds a temperature threshold value determined in accordance with the rated voltage.
